CakePHP: setting defaults for select with optgroups

Question

In a regular select, without optgroups, the following code in CakePHP will make a default value:

'selected' => $ value

Once I have optgroups (select tag with headers), how to set the default value? The previous code does not seem to work.

Answer 1

you can try the following:

echo $this->Form->input('group_id', array('type'=>'select','default'=>'2')); 

resulting in the creation of the following HTML:

 <option value="2" selected="selected">Managers</option> 

Now the two option is displayed instead of any other.

Answer 2

Do not use "value" or "selected", etc., it will break your forms in POST. if you must use the presentation level, use "default".

the best way is to install them from the controller:

 if ($this->RequestHandler->is('post')) { ... } else { $this->data['Model']['field'] = 2; // eg }

Answer 3

 echo $this->Form->input('point', array( 'label'=>'', 'options'=>$list_of_options, 'value'=>$default_value, 'empty'=>'--select--', 'onchange'=>'some_action();' ) );
