Help with first hook

[owner]

First, sorry to ask so many questions, I feel like I am spamming the site :(

 

I am trying to start my first hook, and just for a test, I would like to display something in the footer of my board right before </body> tag. I just don't quite understand the

hook_data and hooks_source tags under the hookfiles tag. How do I code to hook to place the code in certain spots.

 

Not sure if this makes sense, if it doesn't let me know,

Thanks in advance!

No problem, we all gotta start somewhere ;)

 

First you'll need to add a hook in the admin cp. Open System Tab > Manage Hooks > Create New Hook. Where it says Hook Files click the Add New File button.

 

File name in hooks directory: yourhookfilename.php

This file's class name: yourhookfilename

This file's hook type: Template Hook:

The skin group this hook is in: skin_global

The skin function this hook is in: globalTemplate

Type of template hook: if statement

The hook 'id': mainpageContent

Type of template hook: post.endif

 

There is no place to hook exactly above closing body tag, so I've chosen mainpageContent instead. Now save that hook file. And add a file called yourhookfilename.php to your hooks folder. Your hook file will look something like this

 

<?php

class yourhookfilename
{
public $registry;

public function __construct()
{
	$this->registry   = ipsRegistry::instance();
}

public function getOutput()
{
          return "test";
       }
}
?>

 

Then as long as your in IN_DEV mode, you'll be able to export that hook file. We name the file as yourhookfilename.php during development but during import of the hook IPB3 adds _######## random numbers after the hook name.

Ok I got it working, but for some reason I cant see it saying test on the page or in the source code of the page. If I use echo "test"; I can see it displayed at the top of my page though.

 

Do I need to use something special to output it?

[Michael]

Try going to the template bit your hooking into and Save the template bit. Don't have to make any changes.

Nothing. I think it is the php file that is wrong. Should I be using something else than return?

[Michael]

So this is a template hook? No return is the one. Mind sending me the hook file so can see what's wrong?

[owner]

Sent you a PM with the hook source attached.

[Michael]

Can see the pm but no attachments, noticed you deleted the conversation, maybe that deletes attachments.
