Modify field

[Nico Knoll]

Hi,

I try to modify the "InputfieldPageName".

I'm using the render hook, but it returns the whole form so I'm looking for a way to only modify this specific field. Does anone know a way?

Greets,

Nico

You should be able to hook InputfieldPageName::render, but note that it will return markup (and should just be the <input /> tag). If you want to modify some attributes from it or something, then you'd want to hook in before(render). If you want to modify the returned markup you'd want to hook in after(render).

I just replaced the "<p class="...">" with preg_replace. But now I've got the problem that I have to save an additional template file (permalinkFormat) but if I use "___executeSave" I can't use "$this->input->post" because it does a redirect...

It may be better to come in with a 'before' hook and as the class attribute directly, rather than doing a preg_replace. But I don't know the full context here so can't say for certain.

Can you hook in before it? i.e.

$this->addHookBefore('ProcessPageEdit::executeSave', $this, 'myExecuteSave'); 

[Nico Knoll]

YES! It works

What does addHookBefore do exactly?

It literally runs your code before that process - saving the page in your case.

Here are the 4 different kinds of hooks, in order of use. The method you use to hook them is in parenthesis.

1. After hooks – execute after the hooked method (addHook or addHookAfter). Can access/modify return value and arguments.

2. Before hooks – execute before the hooked method (addHookBefore). Can access/modify arguments.

3. Method hooks – adds a new method to a class, assuming it's not already there (addHook).

4. Property hooks – adds a new variable/property to a class, assuming it's not already there (addHookProperty). Rarely used so far.
