This code snippet will show you how to populate a form’s hidden field with the ID of the currently tracked affiliate. The affiliate ID is retrieved from AffiliateWP’s affwp_ref cookie, stored in a variable, and then added to the hidden input.

The snippet below inserts the JavaScript into the page using WordPress’ wp_footer action hook for example purposes only. Feel free to move the code to wherever you need it.


 * Populates a hidden input field with the currently tracked Affiliate's ID.
 * @link
function am_affwp_populate_hidden_field_with_affiliate_id() {
		jQuery(document).ready(function() {
			// Retrieve the affiliate ID from the affwp_ref cookie.
			var affiliateId = Cookies.get( 'affwp_ref' );

			// Populate the hidden field with the AffiliateWP.
			jQuery('#your-hidden-input-field').val( affiliateId );
add_action( 'wp_footer', 'am_affwp_populate_hidden_field_with_affiliate_id' );
