register custom hooks

[PixelPaul]

is it possible to register/create a custom hook within my module for WHMCS. Not use one of the WHMCS hooks.

So people could assign functions to the hook to manipulate some data and return it back to my module after it executes the hook?

such as ...

<?php
add_hook('mymodule_myhook', 1, function($vars) {
    // Perform hook code here...
});

Yes. WHMCS has nothing to do with it. Place hook points in your code and create a sort of autoloader that runs functions if they are in use by your customers. You can also define what parameters you want to push and return.

The logic behind action hooks is not a proprietary thing of WHMCS. It can be applied to any scenario.

yes i could write my own, but it would be best to use one already in place in the core software if available.

WHMCS loads its own hook points and as far as I know there's no way to include your ones.

Yes this is possible, just use the function `run_hook` ie:

 

```

run_hook('MyCustomHook', array());

```

or

```

$return_value = run_hook('MyCustomHook', array());

```

 

Hooks are loaded via `includes/hookfunctions.php` and basically the cache is stored in `global $hooks'`. Not sure why WHMCS doesn't document this at all .. but then again i'm not surprised at all.  If i didn't have a decoded version of WHMCS i wouldn't be able to do 1/4 of the development work I do with WHMCS.
