    <p>I'm trying to save the order of a table with jQuery UI (sortable) to a PHP array.</p> <p>I have simplified it very considerably but this is the basic idea of it. I have a table with a sortable list embedded in it. The table is generated through a PHP <code>foreach</code> involving the multi-dimensional array that is included in another file (<code>config.php</code>).</p> <p><code>config.php</code>: </p> <pre><code>&lt;?php $config = array( "mno" =&gt; array('item 5'), "abc" =&gt; array('item 1'), "ghi" =&gt; array('item 3'), "pqr" =&gt; array('item 6'), "jkl" =&gt; array('item 4'), "vwx" =&gt; array('item 8'), "def" =&gt; array('item 2'), "stu" =&gt; array('item 7'), ); ?&gt; </code></pre> <p>table (<code>index.html</code>): </p> <pre><code>&lt;table cellpadding="2" cellspacing="0" align="center" id="mytable"&gt; &lt;tbody&gt; </code></pre> <pre><code>&lt;?php $i = 0; include 'config.php'; foreach($config AS $name =&gt; $value){ $item = $value[0]; echo ' &lt;tr id="'.$name.'-'.$i++.'"&gt; &lt;td&gt;'.$item.'&lt;/td&gt; &lt;/tr&gt;'; } ?&gt; </code></pre> <pre><code> &lt;/tbody&gt; &lt;/table&gt; </code></pre> <p>scripts (<code>index.html</code>): </p> <pre><code>&lt;!-- Add jQuery library --&gt; &lt;script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"&gt;&lt;/script&gt; &lt;!-- Add jQuery UI library --&gt; &lt;script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; $(document).ready(function() { var fixHelper = function(e, ui) { ui.children().each(function() { $(this).width($(this).width()); }); return ui; }; $("#mytable tbody").sortable({ helper: fixHelper, opacity: 0.5, scroll: false, update: function () { var data = $('#mytable tbody').sortable('serialize'); $.post("edit.php", {'neworder': data}); } }).disableSelection(); }); &lt;/script&gt; </code></pre> <p>The sorting works fine but I don't know how to save the neworder value (<code>$_POST['neworder']</code>) into the array what is in <code>config.php</code>. </p> <p>I think I must use the PHP functions <code>uasort()</code> (or <code>uksort()</code>, <code>uksort()</code>) with the combination of <code>file_put_contents</code> to save the new order in <code>config.php</code>.</p> <p>So something like this: </p> <pre><code>&lt;?php if($_SERVER['REQUEST_METHOD'] == 'POST' &amp;&amp; isset($_POST['neworder'])) { /* Here file_put_contents in config.php the new order. So: $config = array( "mno" =&gt; array('item 5'), "abc" =&gt; array('item 1'), "ghi" =&gt; array('item 3'), "pqr" =&gt; array('item 6'), "jkl" =&gt; array('item 4'), "vwx" =&gt; array('item 8'), "def" =&gt; array('item 2'), "stu" =&gt; array('item 7'), ); Becomes: $config = array( "abc" =&gt; array('item 1'), "def" =&gt; array('item 2'), "ghi" =&gt; array('item 3'), "jkl" =&gt; array('item 4'), "mno" =&gt; array('item 5'), "pqr" =&gt; array('item 6'), "stu" =&gt; array('item 7'), "vwx" =&gt; array('item 8'), ); After this is send by Jquery UI: neworder:abc[]=1&amp;def[]=6&amp;ghi[]=2&amp;jkl[]=4&amp;mno[]=0&amp;pqr[]=3&amp;stu[]=7&amp;vwx[]=5 I've tried this: $filename = 'config.php'; $lines = file( $filename , FILE_IGNORE_NEW_LINES ); $linenumber = 2; foreach( $_POST['neworder'] AS $name =&gt; $val){ $phost = $val[0]; $lines[$linenumber] = ' "'.$name.'" =&gt; array(\'' . $phost . '\'),'; $linenumber++; } file_put_contents( $filename , implode( "\n", $lines ) ); But the '$val' is not send with Jquery only the order. */ } ?&gt; </code></pre>

    1. COSaving data into php files is a bad idea. You can store them in some json or xml format. If you need to do it on a larger scale/more frequently, you have to use a database.

    2. CO@GerritHoekstra Hi I want to help you and think its not so hard but I want to know why you are doing it in this bad way? Can I change some part of it as it became better? I mean in general a tables with two or more columns that can be sorted with jui and as its sorts or as user clicks on a button the new order save? why you don't use JSON or XML format to save? and a file named JSON_Config_reader.php in witch reads that JSON file and make that array?

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.
