Custom signup/registration form fields

This guide explains how to add custom fields to the Sunshine Photo Cart signup form and save the data as customer metadata.

Sunshine Photo Cart provides two action hooks for extending the signup functionality:

• sunshine_signup_fields - Add custom fields to the signup form
• sunshine_after_signup - Process custom field data after successful signup

Here's a complete example adding a "Company Name" field to the signup form:

Adding form fields to the signup form

/**
 * Add company name field to signup form
 */
add_action( 'sunshine_signup_fields', 'add_company_signup_field' );
function add_company_signup_field() {
	?>
	<div class="sunshine--form--field">
		<label for="sunshine-signup-company"><?php _e( 'Company Name', 'your-text-domain' ); ?> <span class="sunshine--form--field--desc"><?php _e( 'Optional', 'your-text-domain' ); ?></span></label>
		<input type="text" name="sunshine_signup_company" id="sunshine-signup-company" autocomplete="organization" />
	</div>
	<?php
}

/**
 * Process company name after signup
 */
add_action( 'sunshine_after_signup', 'process_company_signup_field' );
function process_company_signup_field( $customer ) {
	
	// Validate and sanitize the input
	if ( ! empty( $_POST['sunshine_signup_company'] ) ) {
		$company_name = sanitize_text_field( $_POST['sunshine_signup_company'] );
		
		// Save to customer meta using the customer class method
		$customer->update_meta( 'company_name', $company_name );
	}
}
