如何从Wordpress中的插件相关文件调用函数

Question

i am trying to develop with wordpress but i stuck, that i cannot call function from my plug-in relative .php file

my-plugin-folder/my-plugin-name.php my-plugin-folder/includes/idv_unsubscribe.php

so in my my-plugin-name.php i write:

function adminSettingsMenu(){
  add_menu_page(' Headlines', ' Headlines', 'idv_letters', 'letter-settings', 'pre_made_letter');
  add_submenu_page('letter-settings', 'Unsubscribe', 'Unsubscribe', 'idv_letters', 'unsubscribe-settings', 'callUnsubscribe');
}

later in my-plugin-name.php:

function callUnsubscribe(){
  include plugin_dir_path( __FILE__ ) . '/includes/idv_unsubscribe.php';
}

in idv_unsubscribe.php i am trying to call a function but it is not working

function my_enqueue() {
  exit("asd");
}

if a do this outside a function it exit("123"), but not a exit("asd"):

function my_enqueue() {
  exit("asd");
}
exit("123");

i tried to use add_action, but it is not working, what should i do?

Answer 1

Simply defining a function won't call it. You need to explicitly call it, or add it to an action hook:

function my_enqueue() {
  exit("asd");
}
my_enqueue();

My guess is that you're going to want to add it to an action hook, rather than calling it as I have done above.
