  • jQuery or CSS - How do you make a link in a table row appear underlined even when the cursor is in a

    - by adam
    I have a table of 3-4 columns, the central one being task names that are also links(yet another todo app..groan). Im trying to make it so that whenever the mouse hovers over any part of the table row - not just the link itself - the link will appear underlined. Its a small detail but its been annoying me like hell and i refuse to let it get the better of me now. At first i tried jQuery with a (forgive the obvious syntax errors but this is the jist) $('#row_in_question').hover( function(){ $(this).find(...the link..).toggleClass("highlighted") }, function(){ $(this).find(...the link..).toggleClass("highlighted") } ); with this as a styling for the a element in general .highlighted { text-decoration: underlined; } and it did indeed toggle the highlighted class on that link - however css inheritance got in the way and no visual changes made. Since i previously styled that link to have no underline when not hovered it wouldnt change the style. So how do i go about this? I dont want the whole row to become clickable, I just want the text to become underlined.

  • C++ Constructor initialization list strangeness

    - by Andy
    I have always been a good boy when writing my classes, prefixing all member variables with m_: class Test { int m_int1; int m_int2; public: Test(int int1, int int2) : m_int1(int int1), m_int2(int int2) {} }; void main() { Test t(10, 20); // Just an example } However, recently I forgot to do that and ended up writing: class Test { int int1; int int2; public: // Very questionable, but of course I meant to assign ::int1 to this->int1! Test(int int1, int int2) : int1(int1), int2(int2) {} }; Believe it or not, the code compiled with no errors/warnings and the assignments took place correctly! It was only when doing the final check before checking in my code when I realised what I had done. My question is: why did my code compile? Is something like that allowed in the C++ standard, or is it simply a case of the compiler being clever? In case you were wondering, I was using Visual Studio 2008 Thank you.

  • How can I refactor these script tags?

    - by Shpigford
    I have the following script tags in the <head> so that they don't prompt any security errors when going back and forth between SSL and non-SSL pages. But it just looks hairy. Any way I can combine them or reduce some of the code? <script type="text/javascript">document.write(["\<script src='",("https:" == document.location.protocol) ? "https://" : "http://","ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js' type='text/javascript'>\<\/script>"].join(''));</script> <script type="text/javascript">document.write(["\<script src='",("https:" == document.location.protocol) ?

  • MySQL developer here -- Nesting with select * finicky in Oracle 10g?

    - by John Sullivan
    I'm writing a simple diagnostic query then attempting to execute it in the Oracle 10g SQL Scratchpad. EDIT: It will not be used in code. I'm nesting a simple "Select *" and it's giving me errors. In the SQL Scratchpad for Oracle 10g Enterprise Manager Console, this statement runs fine. SELECT * FROM v$session sess, v$sql sql WHERE sql.sql_id(+) = sess.sql_id and sql.sql_text <> ' ' If I try to wrap that up in Select * from () tb2 I get an error, "ORA-00918: Column Ambiguously Defined". I didn't think that could ever happen with this kind of statement so I am a bit confused. select * from (SELECT * FROM v$session sess, v$sql sql WHERE sql.sql_id(+) = sess.sql_id and sql.sql_text <> ' ') tb2 You should always be able to select * from the result set of another select * statement using this structure as far as I'm aware... right? Is Oracle/10g/the scratchpad trying to force me to accept a certain syntactic structure to prevent excessive nesting? Is this a bug in scratchpad or something about how oracle works?

  • problem finding a header with a c++ makefile

    - by Max
    Hi. I've started working with my first makefile. I'm writing a roguelike in C++ using the libtcod library, and have the following hello world program to test if my environment's up and running: #include "libtcod.hpp" int main() { TCODConsole::initRoot(80, 50, "PartyHack"); TCODConsole::root->printCenter(40, 25, TCOD_BKGND_NONE, "Hello World"); TCODConsole::flush(); TCODConsole::waitForKeypress(true); } My project directory structure looks like this: /CppPartyHack ----/libtcod-1.5.1 # this is the libtcod root folder --------/include ------------libtcod.hpp ----/PartyHack --------makefile --------partyhack.cpp # the above code (while we're here, how do I do proper indentation? Using those dashes is silly.) and here's my makefile: SRCDIR = . INCDIR = ../libtcod-1.5.1/include CFLAGS = $(FLAGS) -I$(INCDIR) -I$(SRCDIR) -Wall CC = gcc CPP = g++ .SUFFIXES: .o .h .c .hpp .cpp $(TEMP)/%.o : $(SRCDIR)/%.cpp $(CPP) $(CFLAGS) -o $@ -c $< $(TEMP)/%.o : $(SRCDIR)/%.c $(CC) $(CFLAGS) -o $@ -c $< CPP_OBJS = $(TEMP)partyhack.o all : partyhack partyhack : $(CPP_OBJS) $(CPP) $(CPP_OBJS) -o $@ -L../libtcod-1.5.1 -ltcod -ltcod++ -Wl,-rpath,. clean : \rm -f $(CPP_OBJS) partyhack I'm using Ubuntu, and my terminal gives me the following errors: max@max-desktop:~/Desktop/Development/CppPartyhack/PartyHack$ make g++ -c -o partyhack.o partyhack.cpp partyhack.cpp:1:23: error: libtcod.hpp: No such file or directory partyhack.cpp: In function ‘int main()’: partyhack.cpp:5: error: ‘TCODConsole’ has not been declared partyhack.cpp:6: error: ‘TCODConsole’ has not been declared partyhack.cpp:6: error: ‘TCOD_BKGND_NONE’ was not declared in this scope partyhack.cpp:7: error: ‘TCODConsole’ has not been declared partyhack.cpp:8: error: ‘TCODConsole’ has not been declared make: * [partyhack.o] Error 1 So obviously, the makefile can't find libtcod.hpp. I've double checked and I'm sure the relative path to libtcod.hpp in INCDIR is correct, but as I'm just starting out with makefiles, I'm uncertain what else could be wrong. My makefile is based off a template that the libtcod designers provided along with the library itself, and while I've looked at a few online makefile tutorials, the code in this makefile is a good bit more complicated than any of the examples the tutorials showed, so I'm assuming I screwed up something basic in the conversion. Thanks for any help.

  • JavaScript audio not playing outside of jQuery function

    - by user1814016
    I know the question title doesn't make much sense, but I can't think of a better way to put it. I am a newbie to jQuery and I'm using this code to fade in a <div> and play a sound: $(document).ready(function(){ $('#speech').fadeIn('medium', function() { play('msg_appear'); var sptx = $('<p class="stext">').text('There is nothing here.'); $('#speech').append(sptx); $('.stext').typeOut({marker: '', delay: 22}); }); }); This code runs fine however the sound plays after the fade-in is complete. I wanted it to play while it was fading in, so I tried placing the play() call outside of the fade-in function like this: $(document).ready(function(){ play('msg_appear'); $('#speech').fadeIn('medium', function() { However, now it's not playing at all. There's no errors on the JavaScript console so I'm unsure if it's a syntax error, and probably something obvious, but I don't know what. play() is a function I found to play audio, here it is if it matters at all. I placed it in the same file the above code is; right above the $(document).ready(). function play(sound) { if (window.HTMLAudioElement) { var snd = new Audio(''); if(snd.canPlayType('audio/ogg')) { snd = new Audio(sound + '.ogg'); } else if(snd.canPlayType('audio/mp3')) { snd = new Audio(sound + '.mp3'); } snd.play(); } else { alert('HTML5 Audio is not supported by your browser!'); } }

  • Converting Source ASCII Files to JPEGs

    - by CommonsWare
    I publish technical books, in print, PDF, and Kindle/MOBI, with EPUB on the way. The Kindle does not support monospace fonts, which are kinda useful for source code listings. The only way to do monospace fonts is to convert the text (Java source, HTML, XML, etc.) into JPEG images. More specifically, due to pagination issues, a given input ASCII file needs to be split into slices of ~6 lines each, with each slice turned into a JPEG, so listings can span a screen. This is a royal pain. My current mechanism to do that involves: Running expand to set a consistent 2-space tab size, which pipes to... a2ps, which pipes to... A small Perl snippet to add a "%%LanguageLevel: 3\n" line, which pipes to... ImageMagick's convert, to take the (E)PS and make a JPEG out it, with an appropriate background, cropped to 575x148+5+28, etc. That used to work 100% of the time. It now works 95% of the time. The rest of the time, I get convert: geometry does not contain image errors, which I cannot seem to get rid of, in part because I don't understand what the problem is. Before this process, I used to use a pretty-print engine (source-highlight) to get HTML out of the source code...but then the only thing I could find to convert the HTML into JPEGs was to automate screen-grabs from an embedded Gecko engine. Reliability stank, which is why I switched to my current mechanism. So, if you were you, and you needed to turn source listings into JPEG images, in an automated fashion, how would you do it? Bonus points if it offers some sort of pretty-print process (e.g., bolded keywords)! Or, if you know what typically causes convert: geometry does not contain image, that might help. My current process is ugly, but if I could get it back to 100% reliability, that'd be just fine for now. Thanks in advance!

  • Please help with C++ syntax for const accessor by reference.

    - by Hamish Grubijan
    Right not my implementation returns the thing by value. The member m_MyObj itself is not const - it's value changes depending on what the user selects with a Combo Box. I am no C++ guru, but I want to do this right. If I simply stick a & in front of GetChosenSourceSystem in both decl. and impl., I get one sort of compiler error. If I do one but not another - another error. If I do return &m_MyObj;. I will not list the errors here for now, unless there is a strong demand for it. I assume that an experienced C++ coder can tell what is going on here. I could omit constness or reference, but I want to make it tight and learn in the process as well. Thanks! // In header file MyObj GetChosenThingy() const; // In Implementation file. MyObj MyDlg::GetChosenThingy() const { return m_MyObj; }

  • OCaml delimiters and scopes

    - by Jack
    Hello! I'm learning OCaml and although I have years of experience with imperative programming languages (C, C++, Java) I'm getting some problems with delimiters between declarations or expressions in OCaml syntax. Basically I understood that I have to use ; to concatenate expressions and the value returned by the sequence will be the one of last expression used, so for example if I have exp1; exp2; exp3 it will be considered as an expression that returns the value of exp3. Starting from this I could use let t = something in exp1; exp2; exp3 and it should be ok, right? When am I supposed to use the double semicol ;;? What does it exactly mean? Are there other delimiters that I must use to avoid syntax errors? I'll give you an example: let rec satisfy dtmc state pformula = match (state, pformula) with (state, `Next sformula) -> let s = satisfy_each dtmc sformula and adder a state = let p = 0.; for i = 0 to dtmc.matrix.rows do p <- p +. get dtmc.matrix i state.index done; a +. p in List.fold_left adder 0. s | _ -> [] It gives me syntax error on | but I don't get why.. what am I missing? This is a problem that occurs often and I have to try many different solutions until it suddently works :/ A side question: declaring with let instead that let .. in will define a var binding that lasts whenever after it has been defined? What I basically ask is: what are the delimiters I have to use and when I have to use them. In addition are there differences I should consider while using the interpreter ocaml instead that the compiler ocamlc? Thanks in advance!

  • IndexOutOfRangeException when a stream is a multiple of the buffer size

    - by dnord
    I don't have a lot of experience with streams and buffers, but I'm having to do it for a project, and I'm stuck on an exception being thrown when the stream I'm reading is a multiple of the buffer size I've chosen. Let me show you: My code starts by reading bufferSize (100, let's say) bytes from the stream: numberOfBytesRead = DataReader.GetBytes(0, index, output, 0, bufferSize); Then, I loop through a while loop: while (numberOfBytesRead == bufferSize) { BufferWriter.Write(output); BufferWriter.Flush(); index += bufferSize; numberOfBytesRead = DataReader.GetBytes(0, index, output, 0, bufferSize); } ... and, once we get to a non-bufferSize read, we know we've hit the end of the stream and can move on. But if the bufferSize is 100, and the stream is 200, we'll read positions 0-99, 100-199, and then the attempt to read 200-299 errors out. I'd like it if it returned 0, but it throws an error. What I'm doing to handle that is, well, a try-catch: catch (System.IndexOutOfRangeException) numberOfBytesRead = 0; ...which ends the loop, and successfully finishes the thing, but we all know I don't want to control code flow with error handling. Is there a better (more standard?) way to handle stream reading when the stream length is unknown? This seems like a small wrinkle in a fairly reasonable strategy for reading streams, but I just don't know if I've got it wrong or what. The specifics of this (which I've cleaned up a little bit for posting) are a MySqlDataReader hitting a LARGEBLOB column. It's working whenever the buffer is larger than the number of returned bytes, or when the number of returned bytes is not a multiple of bufferSize. Because we don't, in that case, throw an IndexOutOfRangeException.

  • Inline function v. Macro in C -- What's the Overhead (Memory/Speed)?

    - by Jason R. Mick
    I searched Stack Overflow for the pros/cons of function-like macros v. inline functions. I found the following discussion: Pros and Cons of Different macro function / inline methods in C ...but it didn't answer my primary burning question. Namely, what is the overhead in c of using a macro function (with variables, possibly other function calls) v. an inline function, in terms of memory usage and execution speed? Are there any compiler-dependent differences in overhead? I have both icc and gcc at my disposal. My code snippet I'm modularizing is: double AttractiveTerm = pow(SigmaSquared/RadialDistanceSquared,3); double RepulsiveTerm = AttractiveTerm * AttractiveTerm; EnergyContribution += 4 * Epsilon * (RepulsiveTerm - AttractiveTerm); My reason for turning it into an inline function/macro is so I can drop it into a c file and then conditionally compile other similar, but slightly different functions/macros. e.g.: double AttractiveTerm = pow(SigmaSquared/RadialDistanceSquared,3); double RepulsiveTerm = pow(SigmaSquared/RadialDistanceSquared,9); EnergyContribution += 4 * Epsilon * (RepulsiveTerm - AttractiveTerm); (note the difference in the second line...) This function is a central one to my code and gets called thousands of times per step in my program and my program performs millions of steps. Thus I want to have the LEAST overhead possible, hence why I'm wasting time worrying about the overhead of inlining v. transforming the code into a macro. Based on the prior discussion I already realize other pros/cons (type independence and resulting errors from that) of macros... but what I want to know most, and don't currently know is the PERFORMANCE. I know some of you C veterans will have some great insight for me!!

  • avoiding code duplication in Rails 3 models

    - by Dustin Frazier
    I'm working on a Rails 3.1 application where there are a number of different enum-like models that are stored in the database. There is a lot of identical code in these models, as well as in the associated controllers and views. I've solved the code duplication for the controllers and views via a shared parent controller class and the new view/layout inheritance that's part of Rails 3. Now I'm trying to solve the code duplication in the models, and I'm stuck. An example of one of my enum models is as follows: class Format < ActiveRecord::Base has_and_belongs_to_many :videos attr_accessible :name validates :name, presence: true, length: { maximum: 20 } before_destroy :verify_no_linked_videos def verify_no_linked_videos unless self.videos.empty? self.errors[:base] << "Couldn't delete format with associated videos." raise ActiveRecord::RecordInvalid.new self end end end I have four or five other classes with nearly identical code (the association declaration being the only difference). I've tried creating a module with the shared code that they all include (which seems like the Ruby Way), but much of the duplicate code relies on ActiveRecord, so the methods I'm trying to use in the module (validate, attr_accessible, etc.) aren't available. I know about ActiveModel, but that doesn't get me all the way there. I've also tried creating a common, non-persistent parent class that subclasses ActiveRecord::Base, but all of the code I've seen to accomplish this assumes that you won't have subclasses of your non-persistent class that do persist. Any suggestions for how best to avoid duplicating these identical lines of code across many different enum models?

  • How To Include Transitive Dependencies

    - by Brad Rhoads
    I have 2 gradle projects: an Android app and a RoboSpock test. My build.gradle for the Android app has . . . dependencies { compile fileTree(dir: 'libs', include: '*.jar') compile ('com.actionbarsherlock:actionbarsherlock:4.4.0@aar') { exclude module: 'support-v4' } } . . . and builds correctly by itself, e.g assembleRelease works. I'm stuck getting the test to work. I gets lots of errors such as: package com.google.zxing does not exist Those seem to indicate that the .jar files aren't being picked up. Here's my build.gradle for the test project: buildscript { repositories { mavenLocal() mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:0.9.+' classpath 'org.robospock:robospock-plugin:0.4.0' } } repositories { mavenLocal() mavenCentral() } apply plugin: 'groovy' dependencies { compile "org.codehaus.groovy:groovy-all:1.8.6" compile 'org.robospock:robospock:0.4.4' } dependencies { compile fileTree(dir: ':android:libs', include: '*.jar') compile (project(':estanteApp')) { transitive = true } } sourceSets.test.java.srcDirs = ['../android/src/', '../android/build/source/r/debug'] test { testLogging { lifecycle { exceptionFormat "full" } } } project.ext { robospock = ":estanteApp" // project to test } apply plugin: 'robospock' As that shows, I've tried adding transitive = true and including the .jar files explicitly. But no matter what I try, I end up with the package does not exist error.

  • Why are we getting a WCF "Framing error" on some machines but not others

    - by Ian Ringrose
    We have just found we are getting “framing errors” (as reported by the WCF logs) when running our system on some customer test machine. It all works ok on our development machines. We have an abstract base class, with KnownType attributes for all its sub classes. One of it’s subclass is missing it’s DataContract attribute. However it all worked on our test machine! On the customers test machine, we got “framing error” showing up the WCF logs, this is not the error message I have seen in the past when missing a DataContract attribute, or a KnownType attribute. I wish to get to the bottom of this, as we can no longer have confidence in our ability to test the system before giving it to the customer until we can make our machines behave the some as the customer’s machines. Code that try to show what I am talking about, (not the real code) [DataContract()] [KnownType(typeof(SubClass1))] [KnownType(typeof(SubClass2))] // other subclasses with data members public abstract class Base { [DataMember] public int LotsMoreItemsThenThisInRealLife; } /// <summary> /// This works on some machines (not not others) when passed to Contract::DoIt, /// note the missing [DataContract()] /// </summary> public class SubClass1 : Base { // has no data members } /// <summary> /// This works in all cases when passed to Contract::DoIt /// </summary> [DataContract()] public class SubClass2 : Base { // has no data members } public interface IContract { void DoIt(Base[] items); } public static class MyProgram { public static IContract ConntectToServerOverWCF() { // lots of code ... return null; } public static void Startup() { IContract server = ConntectToServerOverWCF(); // this works all of the time server.DoIt(new Base[]{new SubClass2(){LotsMoreItemsThenThisInRealLife=2}}); // this works "in develperment" e.g. on our machines, but not on the customer's test machines! server.DoIt(new Base[] { new SubClass1() { LotsMoreItemsThenThisInRealLife = 2 } }); } }

  • Any reason why my $.ajax success callback is not executed in Jquery?

    - by arma
    Hello, Today i discovered that my dev version of my website do not execute success callback, but all other javascript and jquery code is running good. Even my ajax request is performed and i can see response in firebug. $('#login').submit(function(){ var email = $('#l_email').val(); var pass = $('#l_pass').val(); if(email && pass != ''){ var str = decodeURIComponent($(this).serialize()); $.ajax({ type: "POST", url: "login.php", data: str, success: function(msg){ if(msg == 'OK'){ window.location = 'index.php' }else if (msg == 'NOT_OK'){ if(lang == 'lv'){ alert(message); }else if(lang == 'ru'){ alert(message); } }else if (msg == 'EMAIL_NOT_VALID'){ if(lang == 'lv'){ alert(message); }else if(lang == 'ru'){ alert(message); } } } }); }else{ alert('That form is empty.'); } return false; }); The thing is $.ajax part executes fine and i can see response in firebug "OK". But redirect is not happening and even if i replace that redirect with something like alert or console.log nothing comes up. What could cause this? It's really hard to track since firebug gives no errors.

    - by user1902509
    I am fairly new to the whole programming thing, so forgive me if this is a stupid question. It seems odd that I haven't run into it before. I am trying to make an order form for a cake. You fill out the form, submit it, and it will then display the order in a new window, where you then hit "submit," and upload it to the Database. I have a series of If Statements to check for errors in the form before submitting it. Here is a simplified version of the code. Writing means any writing you want on the cake, Name is your name, and cake is what type of cake you want (the default is "None"). try { $name = trim($params->name); $cake = trim($params->cake); $writing = trim($params->writing); if (strlen($name) < 3){ throw new Exception("Please enter Your name."); } if ($cake = "None") { throw new Exception("Please select a Cake" } if ($cake = "Caramel Apple Pie" or $cake = "Pumpkin Pie" or $cake = "Eggnog Pie" and strlen($writing) > 1) { throw new Exception("We are sorry, but you can't write on any of our specialty pies."); } } catch(Exception $x) { $error = $x->getmessage(); } So what is happening is that when I go and hit submit the first time, the correct cake type comes up, but when you submit it the second time, the error comes up saying that I have "None" selected. All the other values are there and remain the same. I think the problem is that the first "IF" statement (Where it says "If($cake = "None")) is automatically changing $cake to "None" because I have tried commenting just that statement out, and it will then change the cake to be "Caramel Apple Pie," which is in the top of the next IF statement. Anyone know why it is doing this? And how to fix it?

  • Reflection for a Field going wrong

    - by TiGer
    Hi, I have been trying to use reflection for a specifiec Field in the android.os.build class, the MANUFACTURER field... I have tried by using this code : try { Class myBuildClass = android.os.Build.class; Field m1 = Build.class.getDeclaredField("MANUFACTURER"); validField = true; manufacturer = Build.MANUFACTURER; } catch(Exception ex) { manufacturer = Build.PRODUCT; System.err.println("getDeviceSpecifics, got an exception during getting Field : " + ex.toString()); } I am gettign the following errors : 06-01 11:26:37.639: WARN/dalvikvm(7342): VFY: unable to resolve static field 2 (MANUFACTURER) in Landroid/os/Build; 06-01 11:26:37.639: WARN/dalvikvm(7342): VFY: rejecting opcode 0x62 at 0x0048 06-01 11:26:37.639: WARN/dalvikvm(7342): VFY: rejected Lmobilaria/android/managementModule/Management;.getDeviceSpecifics ()V 06-01 11:26:37.639: WARN/dalvikvm(7342): Verifier rejected class Lmobilaria/android/managementModule/Management; And when debugging I noticed that InvocationtargetException is continuesly thrown, so I am guessing I haven't been implementing the whole Reflection principle correctly... Any idea where things are going wrong or otherwise on how to implement Refelction for a single Field correctly ?

  • "Invalid Object Format Name" in Crystal Reports

    - by cmays90
    When working with Crystal Report Field Objects and attempting to set "EnableSuppress" to False or alter the position or width of a field object is generating an "Invalid Object Format Name" error. The debugger shows all my code running without error until attempting to actually load the report. At that point, it will run the first couple without problem, then it fails when messing with a field object, and none of the rest will run. The code is shown below. Everything that generates an error is a FieldObject, but not all fieldObjects generate errors. In the code below, everything in Section2 is a TextObject and everything in Section3 is a FieldObject. If condition = True Then 'Lines marked as runs ok, only run when a line that generates an error is not present before it. Report.Section2.ReportObjects("Text7").Left = 7830 'Runs ok Report.Section3.ReportObjects("Field4").Left = 8085 'Runs ok Report.Section2.ReportObjects("Text13").ObjectFormat.EnableSuppress = False 'Runs ok Report.Section3.ReportObjects("Field28").ObjectFormat.EnableSuppress = False 'error Report.Section2.ReportObjects("Text9").Left = 10830 'Runs ok Report.Section3.ReportObjects("Field23").Left = 10830 'error Report.Section3.ReportObjects("Field23").Width = 615 'error Report.Section2.ReportObjects("Text10").Left = 11445 'Runs ok Report.Section3.ReportObjects("Field25").Left = 11445 'Runs ok End If

  • Redirect requests only if the file is not found?

    - by ZenBlender
    I'm hoping there is a way to do this with mod_rewrite and Apache, but maybe there is another way to consider too. On my site, I have directories set up for re-skinned versions of the site for clients. If the web root is /home/blah/www, a client directory would be /home/blah/www/clients/abc. When you access the client directory via a web browser, I want it to use any requested files in the client directory if they exist. Otherwise, I want it to use the file in the web root. For example, let's say the client does not need their own index.html. Therefore, some code would determine that there is no index.html in /home/blah/www/clients/abc and will instead use the one in /home/blah/www. Keep in mind that I don't want to redirect the client to the web root at any time, I just want to use the web root's file with that name if the client directory has not specified its own copy. The web browser should still point to /clients/abc whether the file exists there or in the root. Likewise, if there is a request for news.html in the client directory and it DOES exist there, then just serve that file instead of the web root's news.html. The user's experience should be seamless. I need this to work for requests on any filename. If I need to, for example, add a new line to .htaccess for every file I might want to redirect, it rather defeats the purpose as there is too much maintenance needed, and a good chance for errors given the large number of files. In your examples, please indicate whether your code goes in the .htaccess file in the client directory, or the web root. Web root is preferred. Thanks for any suggestions! :)

  • Error loading il8n console in CakePHP 1.3

    - by inkedmn
    I'm trying to generate the .po files for the site I'm working with. When I run this command from within the console directory: Warning: strtotime(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Los_Angeles' for 'PDT/-7.0/DST' instead in /Users/bkelly/Development/[redacted]/www/trunk/about/trunk/cake/libs/cache.php on line 570 Warning: strtotime(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

This also happens if I issue ./cake il8n help . The bake console seems to load fine (no errors, takes me to the expected menu). I'm running CakePHP 1.3.0 under Mac OSX 10.6 (using MAMP). Cake appears to be functioning normally otherwise. Thanks!

  • Is there a Symfony callback at the termination of a session?

    - by Rob Wilkerson
    I have an application that is authenticating against an external server in a filter. In that filter, I'm trying to set a couple of session attributes on the user by using Symfony's setAttribute() method: $this->getContext()->getUser()->setAttribute( 'myAttribute', 'myValue' ); What I'm finding is that, if I dump $_SESSION immediately after setting the attribute. On the other hand, if I call getAttribute( 'myAttribute' ), I get back exactly what I put in. All along, I've assumed that reading/writing to user attributes was synonymous with reading/writing to the session, but that seems to be an incorrect assumption. Is there a timing issue? I'm not getting any non-object errors, so it seems that the user is fully initialized. Where is the disconnect here? Thanks. UPDATE The reason this was happening is because I had some code in myUser::shutdown() that cleared out a bunch of stuff. Because myUser is loosely equivalent to $_SESSION (at least with respect to attributes), I assumed that the shutdown() method would be called at the end of each session. It's not. It seems to get called at the close of each request which is why my attributes never seemed to get set. Now, though, I'm left wondering whether there's a session closing callback. Anyone know?
