Trying to write a hook to add contribution page name to Main.tpl I'm super close

Question

So I've almost got a hook working to add the name of the contribution page to the main.tpl part of a PCP.

This is what I have so far:

function wordpress_civicrm_buildForm($formName, &$form) {

  if (  $formName == 'CRM_Contribute_Form_Contribution_Main' ) {    
        $ctid = $form->getVar('_contributionPageID');

        $cpagequery = mysql_query("
        SELECT *
        FROM civicrm_contribution_page
        WHERE civicrm_contribution_page.id = $ctid
        ");

        while ($cnamerow = mysql_fetch_array($cpagequery)){
                $cPageName = $cnamerow['title'];
        }

        $form->assign('cPageName', $cPageName);
    }
}

The part that's not working is using the $contributionPageID variable that is already exists on the page. I know the query works, because if I substitute a number for the $contributionPageID I get a result. Any idea how I can pull the contributionPageID variable for use in this hook?

Answer 1

Looks like you are trying to access a variable that's been assigned to the template, not the object. I'd say just access the variable $form->_id directly. Also, I suggest you do not use raw sql queries to retrieve a CiviCRM entity. Here's an example using the api:

function wordpress_civicrm_buildForm($formName, &$form) {
  $page = civicrm_api3('contribution_page', 'getsingle', array(
    'id' => $form->_id,
    'check_permissions' => FALSE,
    'return' => 'title',
  ));
  $form->assign('cPageName', $page['title']);
}

When faced with this situation, I usually examine $form to find it.

For quick and easy lookup, I use CRM_Core_Error::debug to write it to the civi log.
