    <p><strong>EDIT I just realized that I must have had a massive brain fart while writing the abbreviated code sample. See, I'm using smarty. Thus, I'm actually already using Kips's solution, because smarty displays after the session is saved</strong></p> <p>I've been working on implementing a resource manager (for condensing, compressing and minifying CSS &amp; JS) for a PHP site I'm working on and have run into an awfully strange problem. So when a user navigates to index.php, files are added to a resource manager object, which combines them into a single file and are included in the page via either <code>&lt;script src="resource.php?id=123&amp;ext=.js"&gt;</code> or <code>&lt;link href="resource.php?id=123&amp;ext=.css" /&gt;</code></p> <p>What it basically boils down to is that a file path is stored in a session on the accessed page and read from the session on the resource page. In FF, this works perfectly fine. In IE and Chrome, it does not.</p> <p>Here's a much-abbreviated code sample:</p> <p><strong>index.php</strong></p> <pre><code>&lt;?php session_start(); //Do a ton of stuff //Including adding several files to the resource object //Add the resource links to the head $smarty-&gt;append('headSection','&lt;link href="resource.php?id=&lt;?=$resourceID?&gt;&amp;type=.js" /&gt;'); &lt;/head&gt; //Save the resource file which: // - Outputs the file // - Saves a reference to it in session $_SESSION[$resourceID] = $file; //Let Smarty display $smarty-&gt;display($templateFile); ?&gt; </code></pre> <p><strong>resource.php</strong></p> <pre><code>&lt;?php readfile($_SESSION[$_GET['id']] . $_GET['type']); ?&gt; </code></pre> <p>What it seems like to me is that FF waits for an entire page response before making any new requests to the resources required by the page, while IE and Chrome function by starting a new request the second it is encountered. Due to this, this error basically boils down to a race condition.</p> <p>Can anyone confirm that this is indeed the way it works? And if so - how would I work around it?</p>

    1. COCan you be a little more specific about what you're doing, and where? A couple of code snippets along with an explanation of where they happen would be helpful.

    2. CO@Nate: in addition to my answer below, I'd also make sure that you are clearing cookies and cache and restarting the browser before each test. if you aren't doing that, it could be that it works because you already have a session in FF but not in the other browsers.

    3. CO@Kip: I clear cache often enough in IE and Chrome to get around that and it's always a ctrl-shift-r in FF. @timdev: Yea, I know... how's that?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
