Cannot hooks from function

[masitings]

Hi, i have a problem when i want to put the updater separately from the main index plugin. I put the updater on files activation.php in function update_pinterin and then on main index plugin i called do_action function for calling the update_pinterin but it seems not working and the updater was not showing when i activated the plugin.

This is the main index code :

/*
Plugin Name: Pinterin
Plugin URI: https://semanthic.com/
Description: Plugin for automatic
Version: 1.4.5
Author: SEMANTHIC
Author URI: https://semanthic.com
License: SEMANTHIC LTD.
*/

function pinterin()
{
    include_once plugin_dir_path(__FILE__) . '/vendor/autoload.php';
    include_once plugin_dir_path(__FILE__) . '/vendor/updater-plugin/plugin-update-checker.php';
    include_once plugin_dir_path(__FILE__) . '/activation.php';

    do_action('update_pinterin');

}
add_action('plugins_loaded', 'pinterin');

// register_activation_hook(__FILE__, 'pinterin');

This is the files for activation.php

function update_pinterin()
    {
        $myUpdateChecker = Puc_v4_Factory::buildUpdateChecker(
            'https://gitlab.com/masiting/plugins,
            __FILE__,
            'pinterin'
        );
        $myUpdateChecker->setAuthentication('Dasdas');
        $myUpdateChecker->setBranch('plugin');
    }

Please help, thanks.

(I've edited your post to add syntax highlighting to the code blocks.)

Assuming that this is the whole code, it looks like it's missing something: you need to hook the update_pinterin function to the custom update_pinterin action. Like this:

add_action('update_pinterin', 'update_pinterin');
