Question

This code works when I have data rows returned for the messages object but when there isn’t I have it returning NULL in which case I am having a hard time getting this code to still show up correctly so that it works with the tabs plugin I have up. I’m using datatables for my tables.

Anybody have any ideas?

<!-- Start of the main content -->

echo '</td></tr>';

There seems to be an issue with javascript and the instantiation of the tabs plugin. I don’t see the js for the tabs anywhere. But I did see that there is a CI error on the page in a select:

<select name="to" class="required">
                                        <option></option>

                                        <div style="border:1px solid #990000;padding-left:20px;margin:0 0 10px 0;">

<h4>A PHP Error was encountered</h4>

<p>Severity: Warning</p>
<p>Message:  Invalid argument supplied for foreach()</p>
<p>Filename: views/pmsystem.php</p>
<p>Line Number: 121</p>

</div>                                    </select>

which can sometimes mess up javascript stuff.

Are you getting anything in the error console?

Can we see the js?
