This is a non-comprehensive list of functions from the plugin that might be useful.

Content Restriction

Check if user is member

These functions can be useful if you want to add restricted content directly in your PHP templates. It lets you check if a user is subscribed to one or more subscription plans.

1	pms_is_member( $user_id = '', $subscription_plans = array() )

$user_id -> the user ID we want to check, defaults to currently logged in user if empty
$subscription_plans -> array of subscription plan ids the user should be subscribed to

1	pms_is_member_of_plan( $subscription_plans, $user_id = '' )

This is similar to the function above, it just has the parameter in the reverse order.

Both functions will return true or false.

Example:

1
2
3

if( pms_is_member_of_plan( array( 123 ) ) ) {
    echo 'Content for plan 123';
}

Check if post is restricted for current user

1	pms_is_post_restricted( $post_id )

This function lets you check if a particular post is restricted for the current user or not. It will return true or false.

As an example, this function could be useful on an archive page if you want to display a custom icon for posts that the current user can’t access.

Member information

Retrieve information about a member

1	$member = pms_get_member( $user_id );

This function will return a PMS_Member object which contains information about the given user. The object has the following keys:

user_id
username
email
subscriptions – this key contains an array of subscriptions; each subscription is an array with the following keys
- id – id of the membership
- subscription_plan_id
- start_date
- expiration_date
- status
- payment_profile_id

Get a list of members

Using this function you can grab a list of member objects based on certain arguments.

The function also takes a second parameter $count that can be set to `true` to make the function return the number of users instead of the member objects:

1	$members = pms_get_members( $args, true );

Payments

Retrieve information about a payment

1	$payment = pms_get_payment( $payment_id );

This function will return a PMS_Payment object which contains information about a certain payment. The object has the following keys:

id
user_id
subscription_id – this is the Subscription Plan ID, not the ID of the Membership
status
date
amount
type
payment_gateway
transaction_id
profile_id
ip_address
discount_code

Get a list of payments

Using this function you can grab a list of payments based on certain arguments.

Payments meta

Paid Member Subscriptions is using a meta system similar to WordPress Posts or Users for it’s custom payments. You can interact with it through the following functions:

1	pms_get_payment_meta( $payment_id = 0, $meta_key = '', $single = false )

$payment_id – id of the payment
$meta_key – key we want to retrieve
$single – if the function should return a single value or multiple

1	pms_add_payment_meta( $payment_id = 0, $meta_key = '', $meta_value = '', $unique = false )

$payment_id – id of the payment
$meta_key – key we want to add
$meta_value – value we want to add
$single – whether the specified metadata key should be unique for the object. If true, and the object already has a value for the specified metadata key, no change will be made

1	pms_update_payment_meta( $payment_id = 0, $meta_key = '', $meta_value = '', $prev_value = '' )

$payment_id – id of the payment
$meta_key – key we want to update
$meta_value – value we want to set
$prev_value – only update if existing value matches this field

For more info see: https://developer.wordpress.org/reference/functions/update_metadata/

1	pms_delete_payment_meta( $payment_id = 0, $meta_key = '', $meta_value = '', $delete_all = false )

$payment_id – id of the payment
$meta_key – key we want to delete
$meta_value – value we want to delete
$delete_all – If true, delete matching metadata entries for all payments, ignoring the specified payment_id. Otherwise, only delete matching metadata entries for the specified payment_id
