I am devloping a custom plugin for woocommerce. In that plugin the functionality is like it will get all the users and send them email in every 24 hrs.

But here I can't understand how to work with it? I mean how the function will work here?

Any help and suggestion will be really appreciable. Thanks

推荐答案

您需要将插件功能映射到操作，然后将该操作安排到Wordpress cron.

You need to map your plugin function to an action, and then schedule that action to the Wordpress cron.

// ---- Schedule cron event for custom plugin function.
add_action('init', 'custom_plugin_function_event');
function custom_plugin_function_event() {
    if (wp_next_scheduled('custom_plugin_action') == false) {
        wp_schedule_event(time(), 'daily', 'custom_plugin_action');
    }
    add_action('custom_plugin_action', 'custom_plugin_function');
}

// ---- Execute custom plugin function.
function custom_plugin_function() {
    // Do something here
}

上面的示例用于过程代码.将 custom_plugin_function()替换为插件函数的名称.

The above example is for procedural code. replace custom_plugin_function() with your plugin function's name.
