Loading no user details in form

I've followed how to add the userid to the DB Record Loader and gotten it to work using this method:

http://www.chronoengine.com/faqs/2674-how-can-i-edit-a-record-from-a-database-table.html

I put user_id in the request parameter for the DB Record Loader, but then if a non-logged in user fills out the form, since there is a "0" for his ID placed in the form, this data is loaded each time the form is pulled up and no-one is logged in.

How do I prevent having this happen?

Thanks,

Stan

Hi Stan,

I'd probably use a Custom Code action in the On Load event to check the user id and remove any pre-loaded data if it's a guest.

Bob,

This is what I have currently in my custom code just before the DB Record Loader:

<?php
$user =& JFactory::getUser();
$form->data['name'] = $user->name;
$form->data['email'] = $user->email;
$form->data['user_id'] = $user->id;
?>

How do I remove any pre-loaded data? I'm assuming some statement that says if user_id = 0 then do something.

Hi Stan,

Something like this?

<?php
$user =& JFactory::getUser();
if ( $user->id === 0 ) {
  $form->data['name'] = '';
  $form->data['email'] = '';
  $form->data['user_id'] = '';
} else {
  $form->data['name'] = $user->name;
  $form->data['email'] = $user->email;
  $form->data['user_id'] = $user->id;
} 
?>

Bob,

OK - I've tried that code in the custom and data still populates from the record with a userid of 0. Not sure why.

Is there a place to put some code within the DB Record Loader to prevent it from loading the data?

Stan

Bob -

I have resolved this issue. For everyone's benefit reading this string.

If I put this code in below in a custom code event, followed by a DB record loader with the parameter set to user_id, it still populated my form:

$user =& JFactory::getUser();
$form->data['user_id'] = '';

So the answer was the following code which did not populate the form for non-logged in users:

<?php
$user =& JFactory::getUser();
if ( $user->id == 0 ) {
$form->data['name'] = '';
$form->data['email'] = '';

} else {
$form->data['name'] = $user->name;
$form->data['email'] = $user->email;
$form->data['user_id'] = $user->id;
}
?>

I'm not quite sure why I had to take out this line: $form->data['user_id'] = ''; under the if statement, but it certainly causes the form to populate with the table data where the record is "0"
Incidently, having this code: $form->data['user_id'] = '1'; also works for me as well. If anyone has a good explanation for this, it would be interesting although not important for solving this specific issue now.

Hi Stan,

Well solved. I'm not sure why that line would make a difference, it may be related to that way that ChronoForms checks for values before using defaults when it saves the data.
