    <p>I am using ajax to load a php script that shows content based on screen resolution. The script works great, but the url that ajax calls is also called later in the script-- it holds all of the processing information. So, the result is all content is loaded via jquery and then duplicated with php. Example:</p> <pre><code>&lt;script type="text/javascript"&gt; $(document).ready(function() { $.ajax({ url: 'functions/maxresults.php', type: 'GET', data: {h: screen.height, w: screen.width} }).done(function ( data ) { alert("I am working!"); document.getElementById("container").innerHTML=data; }); }); &lt;/script&gt; </code></pre> <p><em><strong>And further down</em></strong></p> <pre><code>&lt;?php include_once("functions/maxresults.php"); ?&gt; </code></pre> <hr> <pre><code>&lt;?php require_once("databasefunctions.php"); ?&gt; &lt;div id="container"&gt; &lt;div id="movieinfo"&gt; &lt;?php include("sidebar.php");?&gt; &lt;?php // get the function include_once ('function.php'); if($_GET['page']) $page = $_GET['page']; else $page = 0; $maxresults = -1; if(($_GET['w']) &amp;&amp; ($_GET['h'])) { $w = $_GET['w']; $h = $_GET['h']; } if ($w == 1920) { $maxresults = 24; } else if ($w == 1600) { $maxresults = 21; } else if ($w == 1440){ $maxresults = 14; } else if ($w == 1366) { $maxresults = 21; } else if ($w == 1024) { $maxresults = 8; } else $maxresults = 6; echo $maxresults; $currentpage = $page; $page = $page*$maxresults; $numpages = QuickQuery("SELECT COUNT(id) FROM movies WHERE visible=1"); $numpages = mysql_result($numpages, 0); $numpages = $numpages/$maxresults-1; $result = GetMoviesByRangeID($page, $maxresults);//Show &lt;maxresults&gt; pages at a time DisplayResults($result); ?&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>I cannot remove the php include or the script won't work at all. Would creating an include_once in the jquery work and if so, how do I code it? </p>

    1. COThis is the wrong approach (since the good one is simply _not_ including the code twice), but you can have a javascript global variable WAS_INCLUDED=true in the php code you include and then have JavaSript check if that variable is defined and execute the code only if it was not. On the other side you can send a GET parameter from js to php.

    3. COWhile I feel like it would be only fair to tell you how you could implement it, I can not give you that method as an answer. My honest-to-heart answer is that you need to re-think your design. there is no way this sort of scenario should happen in a well-thought web design. Why are you facing that issue? Why is the same JavaScript code is included twice? Why is it not in a separate .js file? Is your templating well thought out?

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.
