Learning how to use hooks

[StephenK]

Hello,

 

I am still learning ProcessWire.  I am trying to hook a method in ListProConfig.php.  After the processInput method is called I would like to know the user id of the person that called the method, the page name that was involved in changed lister settings, and then get the new settings.

 

I am having problems getting my hook to work.

In the init of my module I have the following code:

wire()->addHook("ListerProConfig::processInput", function($event){

     $this->wire('log')->save('stephen_ext',"Someone called processInput");

});

 

Even though I know that processInput is called I never get anything written to my log.

Hi, I think I found out the problem.  The method processInput in ListerProConfig has a redirect at the end of the method, so it never properly completes. 

I changed the addHook method to addHookBefore and it seems to be working now.
