• Virtual pages for my plugin

  - by Fini

  Hi, I am currently in the process of making a WordPress Plugin which is going to parse some external data (products) from various web services and present them as normal pages in WordPress. I would like to avoid actually creating the pages programatically and instead just generate them on the fly to avoid any synchronization issues if a product is deleted and so forth. My plugin is going to have a base url in which it will hook on to, for example /products/, and then I would generate each product page by calling /products/some-product-name/. I also anticipate the need for uri's like /products/category/some-category-name/ which I will use to list all items in that category. Since I am new to WordPress plugin development, I am looking for some tips and advice to get me started on the right foot. Any help is highly appreciated ;)

• Issue on passing a checkbox set to an AppEngine script through jQuery Ajax/Json

  - by Jorge

  I have a set of checkboxes with multiple choice allowed. I parse the set this way: if ($("input[name='route_day']:checked").length > 0) { $("input[name='route_day']:checked").each(function(){ if(this.value != null) route_days_hook.push(this.value); }); dataTrap.route_days = $.JSON.encode(route_days_hook); } ...and pull the whole dataTrap to an AppEngine Python script via jQuery ajax. However, the Python script just bugs. If i change dataTrap.route_days value to a string instead of the JSON encoded object, everything works fine. My question is: how can i pass a checkbox set to the script using Ajax and still be able to iterate over it on the script?

• commons-exec: Executing a program on the system PATH?

  - by Stefan Kendall

  I'm trying to execute a program (convert from ImageMagick, to be specific) whose parent folder exists on the path. Ergo, when I run convert from the command line, it runs the command. The following, however, fails: String command = "convert" CommandLine commandLine = CommandLine.parse(command); commandLine.addArgument(...) ... int exitValue = executor.execute(commandLine); If I specify the full path of the convert executable (C:\Program files\...) then this code works. If I don't do this, I get an exception thrown with exit value 4. How do I get commons-exec to recognize the system path?

• Convert any currency string to double

  - by James

  I need to store multiple currencies in SQL server. I understand that SQL won't support all different types of currencies (unless I store it as a string, but I don't want to do that). My idea was to convert all the values from their currency format to a standard double and store that instead. Then just re-format based on the culture info when displaying. However, I have tried doing something like e.g. var cultureInfo = new System.Globalization.CultureInfo("en-US"); double plain = return Double.Parse("$20,000.00", cultureInfo); This doesn't ever seem to work it always throws a FormatException. Even removing the currency symbol and just trying to do this based on the number alone does the same thing. This is just an example I want to support pretty much any type of currency. Is there a standard way of stripping out currency and getting the value as a double?

• How do you assign a variable with the result of a if..else block?

  - by Pierre Olivier Martel

  I had an argument with a colleague about the best way to assign a variable in an if..else block. His orignal code was : @products = if params[:category] Category.find(params[:category]).products else Product.all end I rewrote it this way : if params[:category] @products = Category.find(params[:category]).products else @products = Product.all end This could also be rewritten with a one-liner using a ternery operator (? :) but let's pretend that product assignment was longer than a 100 character and couldn't fit in one line. Which of the two is clearer to you? The first solution takes a little less space but I thought that declaring a variable and assigning it three lines after can be more error prone. I also like to see my if and else aligned, makes it easier for my brain to parse it!

• Injecting an XML fragment into the current document from an external file

  - by makenai

  I'm currently parsing an XML file using REXML and trying to come up with a way of inserting an XML fragment from an internal file. Currently, I'm using some logic like the following: doc.elements.each('//include') do |element| handleInclude( element ) end def handleInclude( element ) if filename = element.attributes['file'] data = File.open( filename ).read doc = REXML::Document.new( data ) element.parent.replace_child( element, doc ) end end Where my XML looks like the following: <include file="test.xml" /> But this seems a little bit clunky, and I'm worried that REXML might not always parse XML fragments correctly due to absence of a proper root node in some cases. Is there a better way of doing this? Concern #2: REXML seems not to pick up my changes after I replace elements. For example, after making a change: doc.elements.each('rootNode/*') do |element| end ..picks up neither the original element I replaced, nor the one I replaced it with. Is there some trick to getting REXML to rescan its' tree?

• Capturing a NSParseErrorException

  - by Martin

  Could someone tell me how I can capture a NSParseErrorException? The Situation: my app downloads a small .plist file. I convert this into dictionary using the string method -propertylist. This normally works fine. I check for a connection before going to retrieve the file, so it works fine if I've got a connection to the internet, and works fine when I don't. However, I discovered a use case that crashes. If I'm at location that requires authetication before connecting to the internet (at Starbucks, say) what's being returned by the app isn't a plist and the attempt to parse it causes the application to crash. So is there a way to transform my code so that the NSParseErrorException is caught and rather than crashing the program I can just skip over this piece of code? NSDictionary *temp = [myDownloadString propertyList]; I tried doing this if ([myDownloadString propertyList]==NSParseErrorException){ //do something } but that didn't work.

• How can Perl interact with an ajax form

  - by Jeff

  I'm writing a perl program that was doing a simple get command to retrieve results and process them. But the site has been updated and now has a java component that handles the results (so the actual data is not in the source code anymore). This is the site: http://wro.westchesterclerk.com/legalsearch.aspx Try putting in: Index Number: 11103 Year: 2009 I want to be able to pro grammatically enter the "index number" and "year" at the bottom of the form where it says "search by number" and then retrieve the results listed next to it. I've written many programs in Perl that simply pass variables via the URL and the results are listed in the source code, so it's easy to parse. (Using LWP:Simple) Like: $html = get("http://www.url.com?id=$somenum&year=$someyear") But this is totally new to me and I don't know where to begin. I'm somewhat familiar with LWP:UserAgent and Mechanize. I'd really appreciate any help. Thanks!

• Safest way to change variable names in a project

  - by kamziro

  So I've been working on a relatively large project by myself, and I've come to realise that some of the variable names earlier on were.. less than ideal. But how does one change variable names in a project easily? Is there such a tool that can go through a project directory, parse all the files, and then replace the variable names to the desired one? It has to be smart enough to understand the language I imagine. I was thinking of using regexp (sed/awk on linux?) tools to just replace the variable name, but there were many times where my particular variable is also included as a part of strings. There's also the issue about changing stuff on a c++ namespace, because there is actually two classes in my project that share the same name, but are in different namespaces. I remember visual stuio being able to do this, but what's the safest and most elegant way to do this on linux?

• Grouping search results with thinking_sphinx plugin for rails

  - by Shagymoe

  I can use the following to group results, but it only returns one result per group. @results = Model.search params[:search_query], :group_by => 'created_at', :group_function => :day, :page => params[:page], :per_page => 50 So, if I display the results by day, I only get one result per day. <% @results.each_with_groupby do |result, group| %> <div class="group"><%= group %></div> <ul class="result"> <li><%= result.name %></li> </ul> <% end %> Do I have to parse the @results array and group them by date manually or am I missing something? Here is the line from the sphinx docs: http://sphinxsearch.com/docs/current.html#clustering "The final search result set then contains one best match per group."

• NSString: EOL and rangeOfString issues

  - by carloe

  Could someone please tell me if I am missing something here... I am trying to parse individual JSON objects out of a data stream. The data stream is buffered in a regular NSString, and the individual JSON objects are delineated by a EOL marker. if([dataBuffer rangeOfString:@"\n"].location != NSNotFound) { NSString *tmp = [dataBuffer stringByReplacingOccurrencesOfString:@"\n" withString:@"NEWLINE"]; NSLog(@"%@", tmp); } The code above outputs "...}NEWLINE{..." as expected. But if I change the @"\n" in the if-statement above to @"}\n", I get nothing.

  - by SIFE

  I tried to parse firefox bookmark(JSON exported version), using this efforts: cat boo.json | grep '\"uri\"\:\"^http\://[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}\"' cat boo.json | grep '"uri"\:"^http\://[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}' cat boo.json | grep '"uri"\:"^http\://[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}"' And few others but all fails, json bookmarked file will look like this: .........."uri":"http://www.google.com/?"......"uri":"http://stackoverflow.com/" So, the output should be like this: "uri":"http://www.google.com/?"

• Rails CSV import, adding to a related table

  - by Jack

  Hi, I have a csv importing system on my app (used locally only) which parses the csv file line by line and adds the data to the database table. This is based on a tutorial here. require 'csv' def csv_import @parsed_file=CSV::Reader.parse(params[:dump][:file]) n = 0 @parsed_file.each_with_index do |row, i| next if i == 0 #ignore the first row course = Course.new course.title = row[0] course.unit_code = row[1] course.course_type = row[2] course.value = row[3] course.pass_mark = row[4] if course.save n = n+1 GC.start if n%50==0 end flash.now[:message] = "CSV Import Successful, #{n} new courses added to the database." end redirect_to(courses_url) end This is all in the courses controller and works fine. There is a relationship that courses HABTM years and years HABTM courses. In the csv file (effectively in row[5] to row[8]) are the year_id s. Is there a way that I can add this within the method above. I am confused as to how to loop over the 4 items and add them to the courses_years table. Thank you Jack

• friendly url in categories

  - by ntan

  Hi to all, i am trying to use friendly url for my categories. Example Database cat_id | parent_id | name | url 1 0 cat1 cat1 2 1 cat2 cat2 My approach to do is to pass the parameter cat with url value for example show.php?cat=cat1 and in .htaccess i must rewrite to /cat1 BUT what about when i want to access cat2. I want to rewrite as cat1/cat2 so the parameter is show.php?cat=cat1/cat2 and then parse the value to secure that cat2 belong to cat1. And so on. I am not using MVC so i have to do it on my own. Please if any other solutions is better please advice or suggest me reading Thank in advance.

• Android Lightweight HTML Template Engine

  - by Anthoni Gardner

  Hello, I am after a very lightweight template engine that supports / can be embedded inside Android programs. I've looked at the MiniTemplator (I think that is how you spell it) and that looks great but it loads in only from file and I need to load templates from string and I am not fully confident in changing that code lol. Can anyone recommend a very lightweight (preferably no jars, single source files etc) that I can use ? I do not need it to parse XML or anything like, just normal HTML files with keywords embedded into them betwee %% tags etc. Regards Anthoni

• Double value not correct on Device

  - by Clue

  int min = Int32.Parse(minutebox.Text); double kj = Convert.ToDouble(a.kj); double res = ((kj * op.koerpergewicht) * min); textbox.Text = res.ToString(); Shows me the correct number (with its punctuation - i. e. 2.33) on my English WP7-Emulator. However it doesn't work on my Device, which is set to German. The value is correct but the point, comma or whatever in that double value isn't shown correct. 43.22 on Emulator - 4322 on Device Why is that?

• Top techniques to avoid 'data scraping' from a website database

  - by Addsy

  I am setting up a site using PHP and MySQL that is essentially just a web front-end to an existing database. Understandably my client is very keen to prevent anyone from being able to make a copy of the data in the database yet at the same time wants everything publicly available and even a "view all" link to display every record in the db. Whilst I have put everything in place to prevent attacks such as SQL injection attacks, there is nothing to prevent anyone from viewing all the records as html and running some sort of script to parse this data back into another database. Even if I was to remove the "view all" link, someone could still, in theory, use an automated process to go through each record one by one and compile these into a new database, essentially pinching all the information. Does anyone have any good tactics for preventing or even just dettering this that they could share. Thanks

• Guaranteed COM object release?

  - by Jurily

  I wrote the following code under the assumption that Excel will die with Monkey: class ExcelMonkey { private static Excel.Application xl = new Excel.Application(); public static bool parse(string filename) { if (filename.Contains("foo")) { var workbook = xl.Workbooks.Open(filename); var sheet = workbook.Worksheets.get_Item(1); // do stuff return true; } return false; } } How do I make sure it does? Do I need to release workbook and sheet separately? I want to have Excel around for the lifetime of the program, it's a huge performance improvement.

Why is it setting the parameter to nvarchar(4000)? How can I fix it? Thanks!

• Changing html content of a div before and after ajax request

  - by R27

  I am trying to change the button "ADD" (in a div) to some text/img as soon as it is clicked. And after the ajax request is processed, in the success block , I want the div to get the button back. I see the ajax request is itself not getting processed. Can someone explain whats my mistake. I just removed the jsfiddle link and pasting the script here to avoid confusion about the dependencies. JS script var ajax_load = "Please wait..."; jQuery(document).ready(function($) { $("#add_button").click(function(event){ var st = $("#add_div").html(); $("#add_div").html(ajax_load); $("#sform").validate({ errorClass: "error", submitHandler: function (form) { alert('inside submit'); $.ajax({ type: "GET", url: 'form.cgi', data: $("#sform").serialize(), success: function (msg) { alert('msg'); $("#add_div").html(st); $("#sform")[0].reset(); } }); } }); }); }); And the html piece is <form id=sform>LABEL <input id=field1 type=text> <div id="add_div"> <input type="button" value="ADD" id="add_button"> </div> </form> I have jquery.validate.min.js script included.

• Invoke Haskell function with heterogeneous arguments?

  - by thurn

  I'm currently working on a Haskell project which automatically tests some functions based on an XML specification. The XML specification gives the arguments to each function and the expected result that the function will provide (the arguments are of many different types). I know how to extract the function arguments from the XML and parse them using the read function, but I haven't figured out how to invoke the function using the arguments I get out. What I basically want is to read and store the arguments in a heterogeneous list (my current thinking is to use a list of type Data.Dynamic) and then invoke the function, passing this heterogeneous list as its argument list. Is this possible? Modifying the functions under test is not an option.

• Jquery DateJs, is there validation for full date?

  - by Cesar Lopez

  Hi all, I just find out about the power of date js, And its great!!! As I am a newbie I was wondering if there is any kind of general validitation for different types of full dates. eg. var d1 = Date.parse('2000-10-18, 10:06 AM'); alert(d1.toString('HH:mm')); If date is ('200-10-18, 10:06 AM'), of course it doesn't like it. So my question is if there is any quick way to validate the full date, rather than having to validate one by one. Thanks.
