How to Add a Phone Number Field in the Woocommerce Registration Form

Introduction:

When it comes to customizing your online store, offering a smooth and user-friendly registration process is key. One way to enhance this experience is by adding a phone number field to your Woocommerce registration form. In this tutorial, we will guide you through the process of integrating a phone number field into your Woocommerce registration form using a simple and straightforward code snippet.

// add field
add_action( 'woocommerce_register_form', 'zamacodes_add_register_form_field' );
function zamacodes_add_register_form_field(){
	
	woocommerce_form_field(
		'phone_number',
		array(
			'type'        => 'tel',
			'required'    => true, // just adds an "*"
			'label'       => 'Phone number'
		),
		( isset( $_POST[ 'phone_number' ] ) ? $_POST[ 'phone_number' ] : '' )
	);
}

// save to database
add_action( 'woocommerce_created_customer', 'zamacodes_save_register_fields' );
function zamacodes_save_register_fields( $customer_id ){
	
	if ( isset( $_POST[ 'phone_number' ] ) ) {
		update_user_meta( $customer_id, 'phone_number', wc_clean( $_POST[ 'phone_number' ] ) );
	}
	
}

Where to Add the Snippet:

You can insert this code into your current theme’s functions.php file. However, it’s recommended to consider using a Child theme or a custom plugin for making such modifications. This practice ensures that your changes won’t be lost during theme updates and allows for better code organization.

Code Explanation:

Step 1: Adding the Phone Number Field

The first step in the process involves adding the phone number field to the registration form. This is achieved using the woocommerce_register_form action hook. When this hook is triggered, it executes the function zamacodes_add_register_form_field() which adds the phone number field to the form.

add_action( 'woocommerce_register_form', 'zamacodes_add_register_form_field' );
function zamacodes_add_register_form_field(){
	// Code to add the phone number field
	// ...
}

Within the zamacodes_add_register_form_field() function, the woocommerce_form_field() function is utilized. This function takes several parameters to define the attributes of the new field. In this case, we specify the field’s type as ‘tel’, set it as required, and label it as ‘Phone number’. The value of the field is populated with any previously submitted phone number or left blank.

woocommerce_form_field(
	'phone_number',
	array(
		'type'        => 'tel',
		'required'    => true,
		'label'       => 'Phone number'
	),
	( isset( $_POST[ 'phone_number' ] ) ? $_POST[ 'phone_number' ] : '' )
);

Step 2: Saving the Phone Number to the Database

After a customer registers with the added phone number field, we need to ensure that the entered phone number is saved to the database. This is accomplished using the woocommerce_created_customer action hook. When this hook is triggered, it executes the zamacodes_save_register_fields() function, which saves the phone number to the user’s metadata.

add_action( 'woocommerce_created_customer', 'zamacodes_save_register_fields' );
function zamacodes_save_register_fields( $customer_id ){
	// Code to save the phone number to the database
	// ...
}

Within the zamacodes_save_register_fields() function, we check if a phone number has been submitted through the registration form. If a phone number is provided, it’s sanitized using the wc_clean() function and then stored in the user’s metadata.

if ( isset( $_POST[ 'phone_number' ] ) ) {
	update_user_meta( $customer_id, 'phone_number', wc_clean( $_POST[ 'phone_number' ] ) );
}

Conclusion:

By following this simple guide, you can easily enhance your Woocommerce registration form by adding a phone number field. This additional field offers your customers a more personalized experience and allows you to stay in touch more effectively. With just a few lines of code, you can significantly improve your online store’s registration process.
