For developers requiring advanced customization beyond the template and block settings, the Membership Card Add On offers several action and filter hooks.

Filters

Hook	Description	Default Behavior
apply_filters( ‘pmpro_membership_card_since_date’, string $since_date )	Filters the “Member Since” date displayed on the card.	Shows the user_registered date (the date the user registered for the site).
apply_filters( ‘pmpro_membership_card_qr_code_size’, string $size )	Filters the dimensions of the generated QR code image.	125×125
apply_filters( ‘pmpro_membership_card_qr_data_other’, object $pmpro_membership_card_user, string $option )	Allows a developer to set a custom value to be encoded in the QR code when qr_data is set to ‘other’ in the Block settings or Shortcode.	Returns no value unless a custom function is hooked in.
apply_filters( ‘pmpro_membership_card_left’, string $left_html, array $args )	Allows customization of the HTML content for the left-hand section of the card.	Displays content based on the elements’ settings.
apply_filters( ‘pmpro_membership_card_right’, string $right_html, array $args )	Allows customization of the HTML content for the right-hand section of the card.	Displays the user avatar and QR code (if enabled).
apply_filters( ‘pmpro_membership_card_get_display_value’, string $value, string $field_key, object $pmpro_membership_card_user, array $args )	Filters the specific value returned for any display element (e.g., display_name, user_email).	Returns the raw data pulled from the database or calculated by the plugin.

Actions

Hook	Description	Notes
do_action( ‘pmpro_membership_card_after_card’ )	Deprecated. Use the new filters or template customization instead.	This hook was used to show additional custom content immediately after the card HTML.
