Here's how to add attributes to form elements

[publicradio]

Hi, I was able to sort this out, thanks to a helpful member of CiviCRM's IRC chat room, so I wanted to share this solution here, in case anyone needs it.

Say you have a form on a contribution page, and you want HTML5 placeholders in the fields. Well, you can create a new extension, install it, and in it use a function like this:

Code: [Select]

function client_civicrm_buildForm($formName, &$form) {
if($formName == 'CRM_Contribute_Form_Contribution_Main' && $form->getVar('_id') == 15) {
$form->updateElementAttr('street_address-3',array('placeholder' => 'xxxxxxxxxxxxx'));
}
}

Where 'client' is the name of your extension and 'street_address-3' is the id of your form field.

also: when you have a select dropdown, the default option says '-select-'. If you want to change this, you can use this code:

Code: [Select]

if ($form->elementExists('country-3')) {
$e = $form->getElement('country-3');
$e->_options[0]['text'] = 'zzz';
    }
