oop - WordPress plugin activation, deactivation and uninstall hook not being triggered

admin管理员组

文章数量:1430064

I am developing a WordPress plugin which requires certain rules to be added to the .htaccess file of the WordPress installation upon activation of the plugin.

Initially, before I switched my code to OOP (with classes and functions) the hooks and this functionality was working. But after I switched it, it doesn't work.

register_activation_hook( __FILE__, array( 'Optimizo', 'activation' ) );

The above code is how I am trying to call the function 'activation' from the class 'Optimizo' which resides in the same file as where I am writing the above activation hook. The 'activation' function has the necessary classes in it which should be called upon activation. Below is the content of the function.

protected function activation() {

    $this->activate();
}

I am just wondering if I wrote the code wrong of is it because that the function is having the protected access specifier or if I am doing something entirely wrong.

PS the function 'activate' resides in another class which is being extended to the 'Optimizo' class.

The function needs to be public, but it can also be static.

For example, from the Akismet plugin:

In the plugin file:

register_activation_hook( __FILE__, array( 'Akismet', 'plugin_activation' ) );

In the Akismet class file:

public static function plugin_activation() {
    ...
}
