  • Is this a well known design pattern? what is it's name

    - by GenEric35
    Hi I have seen this often in code, but when I speak of it i don't know the name of such 'pattern' I have a method with 2 arguments that calls an overloaded method that has 3 arguments and intentionality sets the 3rd one to empty string. public DoWork(string name, string phoneNumber) { CreateContact(name, phoneNumber, string.Empty) } public DoWork(string name, string phoneNumber, string emailAddress) { //do the work } The reason I'm doing this is I to not duplicate code, and allow the existing callers to still call the method that has only 2 parameters. I have associate a few tags to this question, but it probably fit in more categories of questions. Is this a pattern, and does it have a name?

  • Displaying untrusted HTML using PHP

    - by esryl
    I have a read a number of excellent questions and answers today about dealing with user input. I am now using htmlspecialchars() to display user data in the create/edit forms (but accepting the raw input via prepared PDO statements into my database). The main question I know have is, what do you do when you are allowing the user to submit HTML which will then be displayed to the public. Obviously htmlspecialchars() is no longer suitable as it just encodes the tags and renders the content useless for purpose. My application is currently accepting HTML from an admin for product descriptions. This would allow a malicious admin to inject potentially unsafe data into public facing pages. How do people cope with this?

  • Finding an open and closing tag in Regexp

    - by Rixius
    Is there a way to find custom tags in regexp I.e. match {a}sometext{/a} As well as {c=#fff}sometext{/c} So that it finds the entire block of inner content? The problem is the sometext could have another tag as in: {a=http://www.google.com}{b}Hello, world{/b}{/a} The only solutions I can come up with would match from {a... to .../b} when I want {a... to .../a} is there a single regexp solution, or would it be best to match the start, and then use another method to find the end from the back up, and grab it out that way? I'm using PHP 5.2 so I have all the options that entails.

  • How to extract text using regex in Actionscript?

    - by Lost_in_code
    In the HTML below: <a href="link1.php">1</a><a href="link2.php">2</a><a href="link3.php">3</a> How do I extract link1.php,link2.php,link3.php and push them into an array using regex? (There could be N number of <a> tags in the text) [Edit] I'm aware the regex for this is something like href="([^"])*". But I'd like to know how to go about this in Actionscript. Specifically, how can they be pushed into an array in Actionscript?

  • What is a simple way to combine two Emacs major modes, or to change an existing mode?

    - by Winston C. Yang
    In Emacs, I'm working with a file that is a hybrid of two languages. Question 1: Is there a simple way to write a major mode file that combines two major modes? Details: The language is called "brew" (not the "BREW" of "Binary Runtime Environment for Wireless"). brew is made up of the languages R and Latex, whose modes are R-mode and latex-mode. The R code appears between the tags <% and %. Everything else is Latex. How can I write a brew-mode.el file? (Or is one already available?) One idea, which I got from this posting, is to use Latex mode, and treat the code of the form <% ... % as a comment. Question 2: How do you change the .emacs file or the latex.el file to have Latex mode treat code of the form <% ... % as a comment?

  • Strange padding in Safari when using SVG images

    - by Naman Goel
    I thought I was having issues with margins but then on a closer look I found that SVGs are acting funky in Safari 6. I am building a simple Hexagon based website. Of course I used negative vertical margins to for a little overlap to 'inter-lock' the hexagons. And to save space I was using SVG images for the hexagons. It works great in chrome and firefox, but in Safari, there is a strange padding in the SVG images. I'm using simple img tags for the svg images. Everything works when I switch to PNG, but I'd prefer to stick to SVGs. Any insight? Can I perhaps delve into the SVG code and somehow fix the SVG problem in Safari? or is it some sort of bug, that I can do nothing about without browser sniffing?

  • $_GET loading content before head tag instead of in specified div.

    - by s32ialx
    NOT EDITING BELOW BUT THANKS TO SOME REALLY NICE PEOPLE I CAN'T POST AN IMAGE ANYMORE BECAUSE I HAD a 15 Rep but NOW ONLY A 5 becuase my question wasn't what they wanted help with they gave me a neg rep. The problem is that the content loads it displays UNDER the div i placed #CONTENT# inside so the styles are being ignored and it's posting #CONTENT# outside the divs at positions 0,0 any suggestions? Found out whats happening by using "View Source" seems that it's putting all of the #CONTENT#, content that's being loaded in front of the <head> tag. Like this <doctype...> <div class="home"> \ blah blah #CONTENT# bot being loaded in correct specified area </div> / <head> <script src=""></script> </head> <body> <div class="header"></div> <div class="contents"> #CONTENT# < where content SHOULD load </div> <div class="footer"></div> </body> so anyone got a fix? OK so a better description I'll add relevant screen-shots Whats happening is /* file.class.php */ <?php $file = new file(); class file{ var $path = "templates/clean"; var $ext = "tpl"; function loadfile($filename){ return file_get_contents($this->path . "/" . $filename . "." . $this->ext); } function setcontent($content,$newcontent,$vartoreplace='#CONTENT#'){ $val = str_replace($vartoreplace,$newcontent,$content); return $val; } function p($content) { $v = $content; $v = str_replace('#CONTENT#','',$v); print $v; } } if(!isset($_GET['page'])){ // if not, lets load our index page(you can change home.php to whatever you want: include("main.txt"); // else $_GET['page'] was set so lets do stuff: } else { // lets first check if the file exists: if(file_exists($_GET['page'].'.txt')){ // and lets include that then: include($_GET['page'].'.txt'); // sorry mate, could not find it: } else { echo 'Sorry, could not find <strong>' . $_GET['page'] .'.txt</strong>'; } } ?> is calling for a file_get_contents at the bottom which I use in /* index.php */ <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <?php include('classes/file.class.php'); // load the templates $header = $file->loadfile('header'); $body = $file->loadfile('body'); $footer = $file->loadfile('footer'); // fill body.tpl #CONTENT# slot with $content $body = $file->setcontent($body, $content); // cleanup and output the full page $file->p($header . $body . $footer); ?> and loads into /* body.tpl */ <div id="bodys"> <div id="bodt"></div> <div id="bodm"> <div id="contents"> #CONTENT# </div> </div> <div id="bodb"></div> </div> but the issue is as follows the $content loads properly img tags etc <h2> tags etc but CSS styling is TOTALY ignored for position width z-index etc. and as follows here's the screen-shot My Firefox Showing The Problem In Action REPOSTED DUE TO PEOPLE NOT HELPING AND JUST BEING ARROGANT AND GIVING NEGATIVE VOTES and not even saying a word.

  • Query multiple custom taxonomy terms in Wordpress 2.8?

    - by thechrisvoth
    I created a custom taxonomy named 'technologies' but cannot query multiple terms like I can with categories or tags. These querys DO work: query_posts('tag=goldfish,airplanes'); query_posts('technologies=php'); However, neither of the following work correctly: query_posts('technologies=php,sql'); query_posts('technologies=php&technologies=sql'); My objective: Show all posts with a technology of 'php' and all posts with a technology of 'sql' Any ideas? Is this even possible? Thanks!

  • PHP regex help -- reverse search?

    - by Ian Silber
    So, I have a regex that searches for HTML tags and modifies them slightly. It's working great, but I need to do something special with the last closing HTML tag I find. Not sure of the best way to do this. I'm thinking some sort of reverse reg ex, but haven't found a way to do that. Here's my code so far: $html = "<div id="test"><p style="hello_world">This is a test.</p></div>"; $pattern = array('/<([A-Z][A-Z0-9]*)(\b[^>]*)>/i'); $replace = array('<tag>'); $html = preg_replace($pattern,$replace,$html); // Outputs: <tag><tag>This is a test</p></div> I'd like to replace the last occurance of "" with something special, say for example, "". Any ideas?

  • Javascript Hex String to Image

    - by Gunnar Hoffman
    Hello everyone. I'll cut right to the chase. Right now I am developing a web based application. It has a PHP REST based architecture that serves up XML documents. On many of these documents attributes are hex encoded picture strings. On the client side jQuery AJAX fetches an XML document with a picture in it. I need to display said picture in some <img> tags. However my knowledge on such methods is lacking so here I am asking for help. Goal: JavaScript String variable in hex or base64 HTML displayed image. Cross browser is required, or a hack for the ones that do not support it is fine. Thanks, Gunnar

  • Forumotion profile customization using jQuery based on URL

    - by Harvengure
    The idea is have a jQuery snippet (I like Jquery...I can understand it better then regular javascript) that will detect that when it has been run on a profile with a url such as "http://customize.forum-motion.com/profile.forum?mode=viewprofile&u=1" (just as an example)...then upon detecting that it is a url of a profile...fetch data from a specific (and most likely hidden) element before wrapping that data in css tags and appending it to the heady of the current document. In short I'm trying to figure out how to make a sort of profile customization system where users can create their own css. The biggest problem I am having so far is figuring out how to make it so that the snippet can figure out what URL its being run on. Is there a function that can do this in jQuery at all?

  • How to perform COUNT() or COUNT(*)

    - by ninumedia
    I have a list of tags in a database. Ex: villan hero spiderman superman superman I wanted to obtain a sorted list of the tag names in ascending order and the number of times the unique tag appeared in the database. I wrote this code: Ex: SELECT hashtag.tag_name, COUNT( * ) AS number FROM hashtag GROUP BY hashtag.tag_name ORDER BY hashtag.tag_name ASC This yields the correct result: hero - 1 spiderman - 1 superman - 2 villan - 1 How can I obtain the full COUNT of this entire list. The answer should be 4 in this case because there are naturally 4 rows. I can't seem to get a correct COUNT() without the statement failing. Thanks so much for the help! :)

  • Should one use PHP to print all of a page's HTML?

    - by Mala
    Hi So I've always developed PHP pages like this: <?php goes at the top, ?> goes at the bottom, and all the HTML gets either print()ed or echo()ed out. Is that slower than having non-dynamic html outputted outside of <?php ?> tags? I can't seem to find any info about this. Thanks! --Mala UPDATE: the consesus seems to be on doing it my old way being hard to read. This is not the case if you break your strings up line by line as in: print("\n". "first line goes here\n". "second line goes here\n". "third line"); etc. It actually makes it a lot easier to read than having html outside of php structures, as this way everything is properly indented. That being said, it involves a lot of string concatenation.

  • HTML5: Can't drag on-the-fly created <div> tag even though draggable='true' Do I need to "BLESS"

    - by Pete Alvin
    After creating a div on the fly with this markup: $('.circuit').prepend("<div class='component' draggable='true'>TRANSISTOR</div>"); It is NOT draggable itself :( Is jQuery prepend() the correct way to create "live" tags in the DOM? Do I need to somehow bless it a different way to make draggable=true really work? How to I wire it up so that on-the-fly divs can be draggable? AFTER NOTE: I added a static div and that is draggable. INTERESTING: I view both the static and dynamic using FireFox F12 Firebug and they are identical. But one is draggable and one is not!!!

  • Change DIV background color for all inputs in form

    - by Erik
    I have a form with 20 input fields. Each input field is inside a DIV I have a script that changes the background color of the DIV via keyup function along with two other DIV tags. Rather than duplicating the script 20 times for each DIV and Input, is it possible to re-write the script to do all DIV's and their Inputs? <script> $(document).ready(function(){ $("#id").keyup(function() { if($("#id").val().length > 0) $("#in1, #nu1, #lw1, #id").css("background-color", "#2F2F2F").css("color", "#FFF"); else { if($("#id").val().length == 0) $("#in1, #nu1, #lw1, #id").css("background-color", "#E8E8E8").css("color", "#000"); } }); }); </script>

  • Facebook Open Graph Not Showing Object Title

    - by gregavola
    I'm having conflicting reports for our users that people that share Object Graph objects to their wall, are sometimes showing the Object title and other times not. Specifically, every test I do on my own account shows the Object Title, but on their Mobile apps - it doesn't appear. I've tested the Open Graph debugger.So I have a couple of questions: Is there a length limit on the number of characters? Does Facebook not show the whole Object.title on Mobile? Does Facebook scrap the OG tags and if it can't find them or if it timeout do they not receive them? Here is my sample OG url: https://untappd.com/user/gregavola/checkin/35486976 Response from FB: Post on my Wall: What can I do here? What am I missing?

  • etree.findall: 'OR'-lookup?

    - by piquadrat
    I want to find all stylesheet definitions in a XHTML file with lxml.etree.findall. This could be as simple as elems = tree.findall('link[@rel="stylesheet"]') + tree.findall('style') But the problem with CSS style definitions is that the order matters, e.g. <link rel="stylesheet" type="text/css" href="/media/css/first.css" /> <style>body:{font-size: 10px;}</style> <link rel="stylesheet" type="text/css" href="/media/css/second.css" /> if the contents of the style tag is applied after the rules in the two link tags, the result may be completely different from the one where the rules are applied in order of definition. So, how would I do a lookup that inlcudes both link[@rel="stylesheet"] and style?

  • How to select DISTINCT rows without having the ORDER BY field selected

    - by JannieT
    So I have two tables students (PK sID) and mentors (PK pID). This query SELECT s.pID FROM students s JOIN mentors m ON s.pID = m.pID WHERE m.tags LIKE '%a%' ORDER BY s.sID DESC; delivers this result pID ------------- 9 9 3 9 3 9 9 9 10 9 3 10 etc... I am trying to get a list of distinct mentor ID's with this ordering so I am looking for the SQL to produce pID ------------- 9 3 10 If I simply insert a DISTINCT in the SELECT clause I get an unexpected result of 10, 9, 3 (wrong order). Any help much appreciated.

  • How to send argument securely using Process class?

    - by Sebastian
    Hello, I'm using System.Diagnostics.Process to execute an svn command from a windows console application. This is the configuration of the process: svn.StartInfo.FileName = svnPath; svn.StartInfo.Arguments = string.Format("copy {0}/trunk/ {0}/tags/{1} -r head -q --username {3} --password {4} -m \"{2}\"", basePathToRepo, tagName, message, svnUserName, svnPassword); svn.StartInfo.UseShellExecute = false; svn.Start(); svn.WaitForExit(); My problem is that those arguments, which include the svn credentials, are sent (I suppose) in an unsecure way. Is there a way to send these arguments in a secure way using the Process class? Thanks!

  • How to remove one instance of one string in PHP?

    - by Jane
    I have a open source editor on the cms that I am making that automatically inserts a <br /> tag at the beginning of the post it submits to the database. This makes validation a pain, since even though there is no real text being submitted, the form still accepts the break tag as input and prevents the "Please enter some text" error from showing. So I tried to remove the opening break tag by filtering my input like this: substr($_POST['content'], 6); This works as long as the user doesn't press the backspace a couple of times which removes the break tag in which case the first 8 characters of the post gets removed even if they are not a break tag. So how can I remove the first 6 characters of the input ONLY if those first 6 characters are composed of the break tag. Also I don't want to remove all break tags, only the one at the very beginning of the post.
