Set field attributes via API

[renobird]

I'm trying to set an checkbox in the user template to disabled via the API.

Tried this:

$user->of(false);
$user->checkbox_name->attr("disabled","disabled");
$user->save();

Results in:

Fatal error: Call to a member function attr() on a non-object

I think you have to apply the disabled attribute just prior to rendering in the GUI, so a module doing this in its init()...

$this->addHookBefore('Inputfield::render', $this, 'myHook' );

And then having this...

protected function myHook(HookEvent $event)
{
if( 'FieldNameYouWantDisabled'' === $event->object->name )
 $event->object->attr( 'disabled', 'disabled' );
}

...should be enough.

That makes sense, the attributes for fields aren't stored in the DB, so you have to modify them before render.

It's not attributes for fields, but more html attributes on the inputfield render output. As you say correctly it's not something saved with the inputfield.

WillyC,

This value is something that will get set when the user is logged in via a 3rd party authentication provider.

I need superusers and admins to see the checkbox, but not be able to change it.

I would probably set the visibility of that field to "not shown in editor". Rather than have your hook try to adjust attributes of a field, just have it display a message:

if($page->your_checkbox) $this->message("User is logged in"); 
  else $this->message("User is NOT logged in.");

Hi Ryan,

I hadn't ever really looked at the field visibility options, didn't realize there was "not shown in editor".

Showing a message is a great idea — Thanks!
