获取所有WooCommerce订阅

I a need to create a wordpress template to collect all Woocommerce subscriptions, but I'm having trouble with the documentation. I need to know which files to import and which function to call.

Thank you in advice.

Update: Better use wcs_get_subscriptions() as explained in the answer of Andrew Schultz.

As subscriptions are a custom post type, You can get all subscriptions IDs first. Then in a foreach loop you will be able to get the WC_subscription object.

global $wpdb;

// get all subscriptions IDS
$subscriptions_ids = $wpdb->get_col("
    SELECT ID  FROM {$wpdb->prefix}posts 
    WHERE post_type LIKE 'shop_subscription'
");

// Loop through subscriptions Ids
foreach($subscriptions_ids as $subscription_id){
    // Get an instance of the WC_Subscription object
    $subscription = new WC_Subscription( $subscription_id );
}

Then with the $subscription object and the $subscription_id you will be able to do what you want, using WC_Subscription methods to get the desired data or the using subscription ID on dedicated functions.

Official developer Documentation:

• Introduction to Subscriptions Developer Documentation
• Subscriptions Data Structures & Storage

You can use the built in function wcs_get_subscriptions($args) and pass the following $args

$args = array( 'subscriptions_per_page' => -1 );

$subscriptions = wcs_get_subscriptions( $args );

You can even filter by subscription status also in the arguments.
