Hi,

Take a look at the docs:

https://doc.osclass.org/Hooks

osc_add_hook('hook_name', 'function_name');

Maybe this thread could give you some orientation as well:

Thank you so much Teseo for the reply, I read the two links you recommended, I know how hooks work, but I don't know how to implement them within a class object, I tried 

Code: [Select]

osc_add_hook('hook_name', 'function_name'); but it does not work within class object, do you have any idea on how this could work.

[teseo]

Hm... Interesting, indeed you cannot use:

Code: [Select]

osc_add_hook('hook_name', '$this->function_name');
Furthermore, I doubt that a __construct method is the right place to invoke a hook...

So I guess you need to do it indirectly, not inside the class but in index.php:

Code: [Select]

<?php
function esa_delete_user($id) {
    easy_avatar_delete_user::newInstance()->esa_delete_dir($id);
    easy_avatar_delete_user::newInstance()->esa_drop_row($id);
}

osc_add_hook('delete_user', 'esa_delete_user');
?>
Regards

[FredrickReuben]

Yes you are right Teseo

Code: [Select]

osc_add_hook('hook_name', '$this->function_name'); cannot work, I just thought there could be a way I could run the hooks within the class themselves. But I case for now,running  hooks within class objects is not supported by Osclass. So I will just have to use them as you suggest, it works fine though. Thanks so much.

You could map hooks to class' methods

Code: [Select]

// This is valid
osc_add_hook('hook_name', array('class_name', 'method_name'));

// This is also valid
osc_add_hook('hook_name', 'Class_name::method_name');

// This works too
$my_object = new MyClass();
osc_add_hook('hook_name', array($my_ocject, 'method_name'));


In cases 1  & 2, the method has to be static, as the class is not instantiated, in case 3 method don't have to be static, but the class has to be instantiated, so it will not work with hooks in the core of osclass.

Thanks _CONEJO for you answer. Just a clarification, all this happen in index.php file???

[_CONEJO]

yes, or in any other loaded file of your plugin
