    <p>This is my preferred option. Not saying it's perfect but it's what I've been using for a while. Just means that all your error messages are stored in PHP rather than in your JS files (which I prefer). Also note, the below code is untested.</p> <p><strong>Edit</strong>: <em>Just a note as to why I prefer the errors in PHP instead of JS. I normally have a table with my errors in, meaning I can output the error code and message just by saying <code>oh this is ERR-002, output the message associated with it</code>. When somebody phones up with ERR-002, I only need to check the DB (and not trawl through code).</em></p> <p>On your login.php page, you can return a json encoded array that javascript can decode. So in your php:</p> <pre><code>&lt;?php $arrResult = array("message" =&gt; "Could not log you in", "type" =&gt; "error"); // Or the success one: // $arrResult = array("message" =&gt; "You're logged in", "type" =&gt; "success"); echo json_encode($arrResult); ?&gt; </code></pre> <p>Then you can decode this message and use it as an object in javascript, like so:</p> <pre><code>function DisplayLoginError() { var loginForm = document.loginForm; var dataString = $(loginForm).serialize(); $.ajax ({ type: 'POST', url: 'login.php', data: dataString, success: function(strResponse){ var $objResponse = $.parseJSON(strResponse); if ($objResponse.type == "success") { window.location = "home/"; } else { $('#signinAlert').html($objResponse.message).css('display','block'); } } }); return false; } </code></pre>

    1. COPerfect! This is exactly what I was looking for. Was trying to absorb your earlier answer by googling "JSON tutorial". LOL. This helped a lot.

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.

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