1,615,834 | 1,615,835 | jQuery insertion of an anchor doesn't work | <p>My original HTML is:</p>
<pre><code><div class="add-inv-button">Add to Your Game Plan </div>
</code></pre>
<p>I have the following jQuery code:</p>
<pre><code> jQuery('.add-inv-button').click(function(){
jQuery(this).removeClass('add-inv-button');
jQuery(this).addClass('completed-button');
jQuery(this).html('<a class="open-popup" href="#popup01">Done it!</a>'); });
</code></pre>
<p>And I have the following simplelightbox reference:</p>
<pre><code>$(function(){
jQuery("a.open-popup").simpleLightbox({
closeLink:'a.close'
});
})
</code></pre>
<p>This is what's supposed to happen:
After I click on "add-inv-button", the HTML updates, creating an anchor with class "open-popup". After I click on this anchor, the simplelightbox div at #popup01 (on the same page) appears (with z-index of 999).</p>
<p>However, this is what actually happens: After I click on the "add-inv-button", the HTML updates correctly. But when I click on the new anchor, the browser does not jump to the #popup01 simplelightbox on the page. It clears the page and tries to link to www.mydomain.com/#popup01 instead, resulting in an empty page.</p>
<p>It seems like the jQuery simplelightbox doesn't detect the a.open-popup link because the link was added after the page originally loaded. If I refresh the page, then everything works correctly.</p>
<p>How should I fix this? Thanks.</p>

5,140,019 | 5,140,020 | Problem with keyup and shift+tab | <p>I'm writing a small jQuery form routine designed to help a user fill in a group of bank sort code fields. There are 3 fields - when the user has filled in 2 numbers in one field, the cursor is automatically focus() on the next field.</p>
<p>However the problem arises if the user decides to shift+tab back to the previous field. If this field already contains 2 characters, the cursor doesn't stay within that field but jumps forward again.</p>
<p>HTML:</p>
<pre><code><div class="formItem sortCode clearfix">
<input type="text" maxlength="2">
<input type="text" maxlength="2">
<input type="text" maxlength="2">
</div>

$('.sortCode input').keyup(function(event) {
var sortValue = $(this).val();
var sortPosition = $sortCollection.index(this);

if (sortValue.length == 2 && sortPosition != 2) {
sortPosition += 1;
$sortCollection.eq(sortPosition).focus().select();

4,859,285 | 4,859,286 | changing python path on mac? | <p>I would like to change PATH from Python 2.6.1 to 3.1.2. I have both versions installed on my computer but when I type python --version in the terminal I get Python 2.6.1 so thats the current version its "pointing" to. Now if I type Python3.1 it changes the current version to the one I want to use, though the PATH is still 2.6.1. Downloaded with the Python 3.1 package comes a Update Shell Profile.command, so when I run it and then run nano ~/.bash_profile
it says there:
Setting PATH for Python 3.1 the orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.1/bin:${PATH}"
export PATH.</p>
<p>Does this mean that I have changed the PATH or does it just give me instructions how to?!</p>

$fh = fopen($myFile, 'a');
$str = "New Entry...\n";
fwrite($fh, $str);

141,062 | 141,063 | Bizarre issue running PHP background process | <p>I am attempting to run a background process from within a PHP script. I have successfully used this method elsewhere in production environments with no issues. The basic rundown is as follows:</p>
<pre><code>file_put_contents($batch_file, "#!/bin/bash\ncd " . dirname(__FILE__) . "\nphp thescript.php some params\nrm \$0");
chmod($batch_file, 0750);
shell_exec($batch_file . " > /dev/null 2>/dev/null &");
</code></pre>
<p>This method allows the calling script to terminate while $batch_file does it's thing. It's working fine in my dev environment, but on my host (bluehost), the background process simply runs the calling script again AS THOUGH IT WAS THE SAME REQUEST from the browser (causing an endless loop).</p>
<p>Let me illustrate: </p>
<p>The user makes a request for <a href="http://example.com/frontend.php" rel="nofollow">http://example.com/frontend.php</a></p>
<p>frontend.php runs the background task "php backend.php with some params", but the output of that background task is the same as what the user sees when visiting <a href="http://example.com/frontend.php" rel="nofollow">http://example.com/frontend.php</a>. In fact, I can call "php inexistant_file.php" and the output is the same.</p>
<p>If I inspect $_SERVER, it appears to not change, even though I'm calling a DIFFERENT script from a different interface (CLI vs via apache) and passing command-line parameters.</p>
<p>I suspect a weird caching bug/issue, but have disabled w3tc (it's a wordpress site) with no success. </p>

5,753,474 | 5,753,475 | register globals php | <p>I know register globals should not be used but cannot quite understand why? </p>
<p>For example: this is the code that I find so often to demonstrate the security risk of using register globals while passing something like <code>example.com?authorized=1</code> to the script:</p>
<pre><code>if (authenticated_user())
{
$authorized = true;
}
if ($authorized)
{
include '/highly/sensitive/data.php';
}
</code></pre>
<p>My question is if the user has to pass <code>authorized=1</code> in the url he should be aware of the variable names that i use in my script, right? How is that possible?</p>
<p>Also isn't a function like <code>parse_str()</code> which behaves somewhat similar to register globals a security risk too? </p>
