    <p>I'm trying to process database inserts in the background by calling a ajax request on page load. The problem I'm facing is that even if move from the page (the page on which the ajax request is made), it is still waiting for the process in the ajax page to complete.</p> <p>I do not want anything to be output from the ajax page, just start and keep running until all the insert statements are complete. After researching on this subject, I found some solutions but they are not working in my case. I'm using the below code:</p> <h2>index.php</h2> <pre><code>&lt;?php ignore_user_abort(true); ?&gt; &lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;script src="jquery.js"&gt;&lt;/script&gt; &lt;script&gt; $(function(){ $.ajax({ url:'ajax-page.php', success:function(ret) { // of no consequence as I'm not interested in output } }); }); &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;a href="somepage.php"&gt;Click Me&lt;/a&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <h2>ajax-page.php</h2> <pre><code>ob_end_clean(); header("Connection: close"); ignore_user_abort(true); ob_start(); echo (' '); $size = ob_get_length(); header("Content-Length: $size"); ob_end_flush(); flush(); if(session_id())session_write_close(); // background process to start here for($i=1; $i&lt;=10;$i++) { // perform insert query here sleep(1); } </code></pre> <p>Now if I click <strong>Click Me</strong>, the navigation is waiting till the loop (the one in ajax page) has finished executing. Once all 10 records are inserted, the navigation proceeds.</p> <p>AFAIK, I think I'm using all the suggested tricks via <code>ignore_user_abort()</code>, <code>flush()</code>, <code>session_write_close()</code> etc. Am I missing anything else?</p>

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.
