    <p>I have two files:</p> <p><strong>edit.phtml</strong> and <strong>packed_data.php</strong>. I want to post the JS variable (<strong>packed_dat</strong>) to packed_data.php file in order to save it later to an external text file.</p> <p>*In other words i want to save the client-side variable packed_dat into a text file. So i do an AJAX JQuery call like this in the code.*</p> <p>The problem is that although the server informs me about a successful POST, the file <strong>test.txt</strong> is not being created into the same folder, and no text data is being saved.</p> <p>I have checked the folder permissions, they are 0777. I have tried Firebug without telling me anything more.</p> <p><strong>edit.phtml:</strong></p> <pre><code>&lt;div class="content-header"&gt; &lt;table cellspacing="0"&gt; &lt;tr&gt; &lt;td style="width:50%;"&gt;&lt;h3 class="icon-head head-products"&gt;Manage maps&lt;/h3&gt;&lt;/td&gt; &lt;td class="a-right"&gt; &lt;button style="" onclick="sendData()" class="scalable save" type="button"&gt;&lt;span&gt;Save&lt;/span&gt;&lt;/button&gt; &lt;button style="" onclick="what()" class="scalable" type="button"&gt;&lt;span&gt;Show data&lt;/span&gt;&lt;/button&gt; &lt;button type="button" class="scalable back" onclick="javascript:history.back()"&gt;&lt;span&gt;Cancel&lt;/span&gt;&lt;/button&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/div&gt; &lt;?php //$this-&gt;debug(); $droppables = $this-&gt;getDroppable(); $draggables = $this-&gt;getDraggable(); ?&gt; &lt;div id="map_body"&gt; &lt;div id="map_left"&gt; &lt;div id="drop_unmapped" style="height: &lt;?php echo count($draggables)*30+70; ?&gt;px;" class="ui-widget-header drop big"&gt; &lt;p&gt;XML fields&lt;/p&gt; &lt;?php foreach($draggables as $key =&gt; $value) { echo '&lt;div id="drag_'.$value['name'].'" class="ui-widget-content drag"&gt;' .PHP_EOL; echo $value['name'] .PHP_EOL; echo '&lt;/div&gt;' .PHP_EOL; }?&gt; &lt;/div&gt; &lt;/div&gt; &lt;div id="map_right"&gt; &lt;?php foreach($droppables as $value) { ?&gt; jQuery("#drop_&lt;?php echo $value-&gt;getIdentifier(); ?&gt;").droppable({ drop: function(event, ui) { jQuery(this).addClass('ui-state-highlight'); for(key in fields){ if(fields[key] == jQuery(ui.draggable).html()){ fields[key] = 0; } } fields["&lt;?php echo $value-&gt;getIdentifier(); ?&gt;"] = (jQuery(ui.draggable).html()); }, out: function(event, ui) { jQuery(this).removeClass('ui-state-highlight'); } }); &lt;?php } ?&gt; jQuery("#drop_unmapped").droppable({ drop: function(event, ui) { for(key in fields){ if(fields[key] == jQuery(ui.draggable).html()){ fields[key] = 0; } } } }); }); &lt;/script&gt; &lt;script type="text/javascript"&gt; jQuery(function() { &lt;?php foreach($draggables as $key =&gt; $value){ ?&gt; jQuery("#drag_&lt;?php echo $value['name']; ?&gt;").draggable({ revert: 'invalid', snap: '.drop', snapMode: 'inner', snapTolerance: 10, drag: function(event, ui) {jQuery(this).draggable('option', 'zIndex', 10000);} }); &lt;?php } ?&gt; }); var fields=new Object(); &lt;?php foreach($droppables as $value){ echo 'fields["'.$value-&gt;getIdentifier().'"] = 0;' .

    1. COHave you tried running packed_data.php without using post data. I mean, have you verified that you can write any file with that code? Have you verified that your AJAX communication is working?

Querying!

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.

SQuiL has stopped working due to an internal error.

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