Let’s say you require to make the “address” field at checkout bigger. Instead of an “input type = text”, we’d require an “input type = textarea” in HTML. This was my WooCommerce client’s challenge: how can I edit a checkout field input type programmatically? Here’s the snippet!

Snippet: Change Input Field to Textarea @ WooCommerce Checkout Page
/** * @snippet Change Input Field to Textarea @ WooCommerce Checkout * @how-to businessbloomer.com/woocommerce-customization * @sourcecode https://businessbloomer.com/?p=19122 * @author Rodolfo Melogli, Business Bloomer * @compatible WooCommerce 2.4.7 */ // Change address field at checkout add_filter( 'woocommerce_checkout_fields' , 'bbloomer_change_address_input_type', 10, 1 ); function bbloomer_change_address_input_type( $fields ) { $fields['billing']['billing_address_1']['type'] = 'textarea'; return $fields; }
Hi Rodolfo,
Excellent tutorials!
I have added your snippet to an existing line of code that functions for registered users only in a “read-only manner”. However, users can inspect element to change the value attribute and data will save on POST submissions. Examples being user area and checkout forms.
Question is, how would one go about applying your technique to display field values ONLY, I.e. a span tag for registered customers. Essentially removing the input field altogether. The idea is to prevent users from altering data such as email address and mobile number for security purposes.
Thank you

I copied your snippet and placed it on my child-theme’s functions.php and it worked on my CHECKOUT page but the billing_address1 on MY ACCOUNT page still use TEXT as input type. How could I change it to TEXTAREA on MY ACCOUNT page? Thanks.

Hi Rodolfo, thanks for the tutorial. How can I modify this snippet to make checkout fields smaller width? For example, postal code, city and address text boxes are all the same size and the user typically does not require this much space. Do you get Thanks so much
Hey James, thanks so much for your comment! You can use CSS to make them smaller, you won’t require PHP 🙂
