InputfieldWrapper::renderInputfield()

You can add your own hook events that are executed either before or after the InputfieldWrapper::renderInputfield(…) method is executed. Examples of both are included below. A good place for hook code such as this is in your /site/ready.php file.

Hooking before

The 'before' hooks are called immediately before each InputfieldWrapper::renderInputfield(…) method call is executed. This type of hook is especially useful for modifying arguments before they are sent to the method.

$this->addHookBefore('InputfieldWrapper::renderInputfield', function(HookEvent $event) {   // Get the object the event occurred on, if needed   $InputfieldWrapper = $event->object;    // Get values of arguments sent to hook (and optionally modify them)   $inputfield = $event->arguments(0);   $renderValueMode = $event->arguments(1);    /* Your code here, perhaps modifying arguments */    // Populate back arguments (if you have modified them)   $event->arguments(0, $inputfield);   $event->arguments(1, $renderValueMode); });

Hooking after

The 'after' hooks are called immediately after each InputfieldWrapper::renderInputfield(…) method call is executed. This type of hook is especially useful for modifying the value that was returned by the method call.

$this->addHookAfter('InputfieldWrapper::renderInputfield', function(HookEvent $event) {   // Get the object the event occurred on, if needed   $InputfieldWrapper = $event->object;    // An 'after' hook can retrieve and/or modify the return value   $return = $event->return;    // Get values of arguments sent to hook (if needed)   $inputfield = $event->arguments(0);   $renderValueMode = $event->arguments(1);    /* Your code here, perhaps modifying the return value */    // Populate back return value, if you have modified it   $event->return = $return; });
