Author Topic: Suggestion: Add an "invokehook" hook that is called every time a hook is called (Read 1533 times)

This is just a suggestion to add a call to a module hook function that would be called every time a hook is called. The new hook could look like this:

Code: [Select]

/**
 * This hook is called before every hook function is called.  Useful to trap everything, to see which
 * hooks are called when.  Also for any general functionality across all hooks (like saving globals
 * perhaps?)
 * 
 * @param string $fnName      hook function name being invoked
 * @param mixed $arg1         argument number 1 passed to the hook function
 * @param mixed $arg2         argument number 2 passed to the hook function
 * @param mixed $arg3         argument number 3 passed to the hook function
 * @param mixed $arg4         argument number 4 passed to the hook function
 * @param mixed $arg5         argument number 5 passed to the hook function
 */                 
function nafyhooks_civicrm_invokehook ( $fnName, $arg1, $arg2, $arg3, $arg4, $arg5 ) {
	trigger_error("nafyhooks_civicrm_invokehook called for fnName $fnName");
}

I've modified the file civicrm/CRM/Utils/Hook/Drupal.php to implement this in my Drupal CiviCRM deployment (inserted after line 45):

Code: [Select]

                $fnInvokeHookName = "{$module}_civicrm_invokehook";
                if ( function_exists( $fnInvokeHookName ) ) {
                    $fnInvokeHookName( $fnName, $arg1, $arg2, $arg3, $arg4, $arg5 );
                }

other than adding a debug statement and tracing the hook calls, what purpose would this hook solve?
