Author Topic: Removing options in select boxes using a hook (Read 2034 times)

Hello,

Every now and again, I'd like to remove some of the options available in select form elements.

For example, to enforce workflows like 'admin staff cannot set contributions to received - only to in progress' Or to remove the email and phone options from the activity types that appear in 'CRM_Activity_Form_Activity'.

I presume that there is a method in the $form object but am unsure of where to start to look for that.

Should I be looking here: http://pear.php.net/package/HTML_QuickForm/?

Does anyone have any snippets they would be willing to share?

Thanks a lot,
Michael

I am not sure these are ideal solutions / ways, but I think hook_civicrm_buildForm will serve needful.

1. You need to register (add) new quick form element w/ same name and here you can modify or give select option list that you want.
this newly register quick form element w/ your modified options is going to suppress original element.

( make sure to properly overwrite original quick form element, like its attributes and so on ... )

OR

2. modify existing quick form element options.
eg : activity types

Code: [Select]

function civicrm_civicrm_buildForm( $formName, &$form ) {
    if ( $formName == 'CRM_Activity_Form_Activity' ) {
        //first check given element exists in quick form.
        if ( $form->elementExists( 'activity_type_id' ) ) {
            //get element.
            $element =& $form->getElement('activity_type_id'); 
            crm_Core_error::debug( 'options', $element->_options );
  
            //here you can play w/ options and you can modify those.
           //also you can add new options w/  $element->addOption( );
        }
    }
}

hope this help

Hi,

I'd go jQuery, not very secure, but dead easy

$('#paymentoption #direct').remove();

Depending of the form you might or might not have an id for each select value, change the code accordingly, or add a id= in the template (assuming that isn't a pregenereated html blob from php)

Thanks Xavier and Kiran,

I wonder which is most future proof in terms of upgrades.

Where do you stick the jQuery Xavier? In the template? If that's the case, I think it might be better for me to use the hook because I can specify all the forms in the if clause of the hook. I'll let you know how I get on...

Hi,

two big options, depending on how many forms and pages are supposed to be impacted:

- I create a custom template that override the default for that element (contrib/search...) and add the jquery in that
- I put it in the page tpl of the theme, and if the page contains the right id/class, it applies the changes, otherwise silently does nothing.
