hook buildForm error upon clicking "add" link
September 25, 2009, 06:06:30 pm
I'm using civicrm_buildform hook to freeze the external_identifier since I don't want its value to be changed when a contact is edited.

I use the following code, which works good.
Code: [Select]
if ($formName == "CRM_Contact_Form_Contact") {
$elem = $form->getElement('external_identifier');
$elem->freeze();
}
But when I select an "add" link (f.i. to add an email address) the following error happens:

Code: [Select]
[message] => QuickForm Error: nonexistent html element
    [mode] => 16
    [debug_info] => Element 'external_identifier' does not exist in HTML_QuickForm::getElement()
    [type] => HTML_QuickForm_Error
    [user_info] => Element 'external_identifier' does not exist in HTML_QuickForm::getElement()
    [to_string] => [html_quickform_error: message="nonexistent html element" code=-3 mode=callback callback=CRM_Core_Error::handle prefix="QuickForm Error: " info="Element 'external_identifier' does not exist in HTML_QuickForm::getElement()"]
)

It looks the buildform hook is fired again by the "add" link and that the form element cannot be found.
Thanks,
Joop

hey joop:

how about using the following piece of code:

Code: [Select]
if ($formName == "CRM_Contact_Form_Contact" &&
            $form->elementExists( 'external_identifier' ) ) {
$elem = $form->getElement('external_identifier');
$elem->freeze();
}

Hello Lobo,
Thanks, testing whether the element is there solved it.
Regards, Joop

Would something have changed between 4.1.2 and 4.2.2 to cause this problem to crop up in a couple of places when it didn't appear otherwise?  I'm freezing the "register multiple participants" field in Event Online Registration configuration, and then when I try and add a profile (a link further down the page that uses AJAX), it throws an element not found error.  This did not happen in 4.1.2.
