    <p>I have what used to be a working form validation, including the remote check of a username as available. we've added a lot of other javascript to the script.js file and at some point recently the remote part of this broke. There is only one form field being checked by validate, the new_name field. It is required (works) and must be available (doesn't work).</p> <p>Here is the jQuery:</p> <pre><code> $('#nickname_form').validate({ rules: { new_name: { required: true, remote: { url: '/api/screenname_unique/', type: 'post' } } }, messages: { new_name: { required: 'Please choose a Forum Username.', remote: 'That Username is already taken or contains invalid characters.' } } }); </code></pre> <p>As I said the above used to work, with no changes. I've checked the rest of the script.js file and no errors are showing up. Also, in the site, we're not seeing JS errors anywhere. If I remove the remote portion of the above code, the required check works and the form will submit when there is a value in the field. </p> <p>With remote in place, the form will not submit, and whether the ajax response from the remote call is true or false, there is no jQuery validate error message shown. Here is the page called by remote. It works fine as far as the response it is giving for a given value:</p> <pre><code>&lt;?php header('Content-type: application/json'); //get the post value $screen_name = $_POST['new_name']; //get their member_id $member_id = $this-&gt;EE-&gt;session-&gt;userdata['member_id']; //return false if no screen_name provided if((!$screen_name) || (!$member_id)) { echo json_encode(false); exit; } else { //there is a screen_name //Regex Check for valid chars $valid = !preg_match('/[^a-z0-9_ -]/i',trim($screen_name)); if (!$valid) { echo json_encode(false); exit; } //SQL $results = $this-&gt;EE-&gt;db-&gt;query("SELECT member_id FROM exp_members WHERE screen_name = '$screen_name' and member_id &lt;&gt; '$member_id' limit 1"); if ($results-&gt;num_rows() &gt; 0) { echo json_encode(false); } else { echo json_encode(true); } } </code></pre> <p>?></p> <p>I am not really sure where to go from here. Ideas?</p>

    1. COHave you used `console.log` or watched the ajax calls to debug the problem?

    2. COI've watched with Firebug and the ajax calls are returning 200 OK along with true or false appropriately. The function is working fine - the form just won't submit or respond to an unavailable username correctly.

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.
