    <p>I have a table that prints out all available cameras. It uses a form to change these settings. The problem is that the form only updates the last camera in the entry. In other words if I change the form and hit "Apply" for the last camera in the list it will work. If I change the form for any other camera in this list it changes the one to have the same settings as the last camera in the list. There are no issues with any values as far as I can tell. </p> <p>Sorry for the long dump here, but without being able to narrow down the problem I thought I should include the bulk of it:</p> <pre><code>// Dont allow direct linking defined('_JEXEC') or die('Direct Access to this location is not allowed.'); //get current user $user =&amp; JFactory::getUser(); // get a reference to the database $db = &amp;JFactory::getDBO(); $query_camera_name = "SELECT camera_id, camera_name, camera_status, camera_quality, camera_hash, camera_type FROM #__cameras WHERE user_id=".$user-&gt;id." AND camera_status!='DELETED'"; $db-&gt;setQuery($query_camera_name); //get number of cameras so we can build the table accordingly $db-&gt;query(); $num_rows = $db-&gt;getNumRows(); // We can use array names with loadAssocList. $result_cameras = $db-&gt;loadAssocList(); if (isset($_POST['apply_changes'])) { //process changes to camera options $camera_id = $_POST['camera_id']; $camera_status = check_input($_POST['camera_status']); $camera_name = check_input($_POST['camera_name'], "You entered an empty camera name. Enter another name and apply changes."); $camera_quality = check_input($_POST['camera_quality']); $query_insert_camera = 'UPDATE `#__cameras` SET `camera_status` ="'.$camera_status.'", `camera_name` ="'.$camera_name.'", `camera_quality` ="'.$camera_quality.'"

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.
