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.
Sorry for the long dump here, but without being able to narrow down the problem I thought I should include the bulk of it:
// Dont allow direct linking
defined('_JEXEC') or die('Direct Access to this location is not allowed.');
//get current user
$user =& JFactory::getUser();
// get a reference to the database
$db = &JFactory::getDBO();
$query_camera_name = "SELECT camera_id, camera_name, camera_status, camera_quality, camera_hash, camera_type FROM #__cameras WHERE user_id=".$user->id." AND camera_status!='DELETED'";
$db->setQuery($query_camera_name);
//get number of cameras so we can build the table accordingly
$db->query();
$num_rows = $db->getNumRows();
// We can use array names with loadAssocList.
$result_cameras = $db->loadAssocList();
if (isset($_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.'" WHERE `camera_id`='.$camera_id;
$db->setQuery($query_insert_camera);
