$form_state triggering_element seems to get last button rendered not last button clicked?

Just set the #name when writing the button. Thanks a ton!

I set the diffferent "#name" for each button.
Also don't forget to set the #type = 'submit' instead of a 'button'

Thank you

If button one is clicked a second time,

ie click Button1, click Button2, click Button1, click Button1.

It the ajax call for button 1 will fire for the last click. But for the third click, Button2's ajax callback will still fire.

Okay what I've decided to do is this...

Test for $form_state['triggering_element'] and if it exists set a variable $input_trigger to $form_state['input'][_triggering_element_name].

This variable can now fire all relevant functions that apply to that trigger.

Each of the elements now have the same ajax callback.
Inside this callback, switch $form_state['input'][_triggering_element_name] and apply the correct ajax commands to the correct trigger.

Is this method advisable?

$addform_builder($form,$form_state){

 ...

 if(array_key_exists('triggering_element',$form_state)) {
		
      $input_trigger = $form_state['input']['_triggering_element_name'];//$form_state['triggering_element']['#name'];//
		
      _addform_triggers($form, $form_state, $input_trigger);
				
 }

 $form['buttons']['updatediscipline'] = array(

 );

 $form['operation'] = array(
       '#markup'=>'<pre>'.print_r($form_state['input'],TRUE).'</pre>'),
       '#prefix' => '<div id = "fcc_op_replace" >',
		'#suffix' => '</div>',
 );

  return $form;

}

function fcc_addform_buttons_callback(&$form, &$form_state){
	
	$input_trigger = $form_state['input']['_triggering_element_name'];
	$commands = array();
	switch($input_trigger){
		case 'quantitybutton':
		break;
		case 'refresh';
		break;
		case 'clients':
		break;
		case 'updatediscipline':
			$commands[] = ajax_command_alert(t('ajax: updatediscipline is working'));
			$commands[] = ajax_command_replace("#some_container", render($form['some_container']));
			$commands[] = ajax_command_replace("#fcc_op_replace", render($form['operation']));	
		break;
		case 'chk_reset':
		break;
		case 'update_venue_jd':
			$commands[] = ajax_command_alert(t('ajax: update_venue_jd is working'));
			$commands[] = ajax_command_replace("#details_container", render($form['details_container']));
			$commands[] = ajax_command_replace("#fcc_op_replace", render($form['operation']));		
		break;
		case 'startdate':
		break;
	
	}
	
	return array(
		'#type' => 'ajax',
		'#commands' => $commands,	
	);
	die();
}

Anyway....

A little further reading of _form_builder_handle_input_element(). It seems that if the $form_state['triggering_element'] is set at _form_element_triggered_scripted_submission, it should skip the following _form_button_was_clicked(). But it doesn't.

Have I missed something vital?

Any advise would be great, thanks again.
