I will be more specific.
I have value (user number) in row AUTORIZOVANO in db and I need to set checkbox to checked/unchecked depending on value from db.
I did try something like that

if (isset($form->data['faktury']['autorizovano']))
  {
    $form->data['faktury']['temp']=$form->data['faktury']['autorizovano']; // move value to temp var for next use
    $form->data['faktury']['autorizovano']=1;  // set ckeckbox as checked
  }

but checkbox didnt checked and I think that is wrong.

Hi Bob,
I wrote it, value in db is integer - user number from joomla.
I want to: if checkbox is checked (authorized), then set number of logged user to row AUTORIZOVANO.
problem is that I cant affect checkbox to check or uncheck in code.

Hi homeopat,

A checkbox can't have a variable number as a value. I don't understand what you are trying to do here.

Hi Bob,
when is checkbox marked (1) then userID must be put to AUTORIZOVANO row in db.
when I open existing record and AUTORIZOVANO row has value > 0 then checkbox must be marked (1).

do u understand now?
thank you

Hi homeopat,

You have to do this with Custom Code actions:

In the form ON Submit before the DB Save action

<?php
$temp = '';
if ( !empty($form->data['checkbox_name']) && $form->data['checkbox_name'] == 1 ) {
  $user = \JFactory::getUser();
  $temp = $user->id; 
}
$form->data['AUTORIZOVANO '] = $temp;
?>

and in the On Load event after the DB Read and before the HTML (render form) action

<?php
$temp = '';
if ( $form->data['AUTORIZOVANO '] > 0 ) {
  $temp = 1;
}
$form->data['checkbox_name'] = $temp;
?>

I'm not clear what the actual element names are so you'll need to edit those.

Hi Bob,

I have had set something like that in code ..... but checkbox is not set after modification of code.
I think that problem is that checkbox dont work with value but with word checked in element.
I see in debugger that checkobox has value = 1 but didnt checked.
