CiviCRM Community Forums (archive)

Hello everybody.

I have been playing with hooks, well, that is a lie, I have been fighting with them, shouting and using terrible language at them.

They wouldn't fire, you see. Nothing. I tried various ways, I read, ok, more like indepth skimming the documention. But I just could not make them fire.

The constructor would be called, but the hook wouldn't.

This wouldn't work
function hook_civicrm_buildForm( $formName, &$form ){
   echo "I AM HERE"; exit;
}


In a desparate measure I tried.
function civicrm_buildForm( $formName, &$form ){
   echo "I AM HERE but I don't think I should be"; exit;
}

It worked

I have also test this now with
function civicrm_postProcess( $formName, &$form ){
  echo "YAY";exit;
}

function hook_civicrm_postProcess( $formName, &$form ){
  echo "BOOO";exit;
}


Can some one explain to me why the former does not work, yet the latter does work. Why does the documentation say to prefix the hooks with hook_ when this does not work?
If I have missed something labelled "read this you stupid developer before hooking in", I apologise and if can send me a link to this, I can bring my stress levels down


cheers

Thanks Eileen, that makes sense.

Just to show I am not a total idiot, I am using Joomla, hence why had no idea about this. I would recommend adding something in bright red pt 32 marquee blink text to let the Joomlaers know


*other question removed as it was stupidity on behalf *

I've never seen that second syntax before - I've never seen CiviCRM refer to 'civi' rather than CiviCRM - there's not a missing '=' in your module or another is there - ie

if($formname = 'civi_event_registration'){

rather than


if($formname == 'civi_event_registration')

causing the form to be renamed.

It would be great if you could update whatever documentation you used with the missing information for Joomla! people
