在Wordpress插件中包含类的正确方法是什么？

Question

Forgive me, but I cannot seem to find this seemingly simply answer anywhere.

I have one class (for interacting with MailChimp API) which I am including in my Wordpress plugin. The problem is, using include inside an action hook isn't working.

For example:

function load_class() {
    include( plugin_dir_path(__FILE__) . 'includes/MailChimp.class.php');
    }
add_action('plugins_loaded', 'load_class');

doesn't work.

Can someone tell me (with an example) how I should include a php class from within a Wordpress plugin?

EDIT: Corrected class name in add_action() function

Answer 1

You said

I have one class (for interacting with MailChimp API) which I am including in my Wordpress plugin.

Why, you are using a hook here ? You can directly include this class in your working plugin. just, include MailChimp.class.php from within your plugin file, as normally you do in php . Also, check the another answer, you have made another mistake and it'is

add_action('plugins_loaded', 'load_mailchimp_class');

should be

add_action('plugins_loaded', 'load_class');

but not useful here. you don't need to use this. You asked for an example, include the class from your plugin.php file before you use it, like

include( plugin_dir_path(__FILE__) . 'includes/MailChimp.class.php');

Answer 2

Your add_action() should read add_action('plugins_loaded', 'load_class'); .
