[kreativmonkey]

Hi,

i would like to modify the template settings pages and add some options for a notification module. How can i do that and how can i get this information back in the module?

Thanks for your help!

Hi kreativmonkey,

did you read the tutorials about creating modules? https://processwire.com/api/modules/
or how to use hooks? https://processwire.com/api/hooks/

If so, create a module which hooks in the hookable method, which you want to modify for your needs.
Have a look inside:  /wire/modules/Process/ProcessTemplate/ProcessTemplate.module

If you need more specific help post it here.

I think i found the right hook to add some settings to the templates edit Page:

protected function ___buildEditForm(Template $template) {

so i can use

....
addHookBefore('ProcessTemplate::buildEditForm', buildEditForm($event)) 
....
protectet function buildEditForm(Template $template) {
                $t = new InputfieldWrapper();
		$t->attr('title', $this->_x('Notification', 'tab'));
		// $t->head = $this->_('Optional usage and placement in the page tree');
		$t->attr('class', 'WireTab'); 
		$t->attr('id', 'tab_notification');
  		$t->add($this->buildEditFormNotification($template)); 
		$form->add($t); 
...}
protected function buildeditFormNotification(Template $template){
....}

do i need to Hook the executeSave() to save my fields? Is addHookBefore the right one ore do i need addHook ore addHookAfter?....

Thanks for your help!

You probably want to use addHookAfter and add just your additions to the returned form object. With the other hooks you cannot modify the form, as it's created inside the function. Also make sure you're getting your hooks correct. Either use a function (without parameters) or a anonymous function. Also the function does not receive a template anymore, but the $event variable. Here you've an example using an anonymous function to add a new field into the form: https://processwire.com/talk/topic/11069-sorting-images-in-backend/?p=103687
