Woocommerce Readonly Billing Fields - wordpress

Question

I have some e-commerce website where the customer billing address is predefined on the back-end.
I need to set the "Billing Address" fields as 'readonly' to avoid the customer to replace the information placed there... but i don´t know how/where to do it...
Is it possible?

Answer 1

Put following code in your theme's "function.php" file.
add_action('woocommerce_checkout_fields','customization_readonly_billing_fields',10,1);
function customization_readonly_billing_fields($checkout_fields){
$current_user = wp_get_current_user();;
$user_id = $current_user->ID;
foreach ( $checkout_fields['billing'] as $key => $field ){
if($key == 'billing_address_1' || $key == 'billing_address_2'){
$key_value = get_user_meta($user_id, $key, true);
if( strlen($key_value)>0){
$checkout_fields['billing'][$key]['custom_attributes'] = array('readonly'=>'readonly');
}
}
}
return $checkout_fields;
}
This function checks if the address fields have value (i.e. if the address is specified), and if it has value, makes the field/s readonly. Else keeps the fields open to add data for user.
Hope this helps.

You have not specified which form you want to customize making the billing address fields read-only. Normally the billing address fields appear on two types of forms on a WooCommerce site:
On a checkout form
On a my-account/edit-address/billing/ page
If your case is the first one, then zipkundan's answer is the best one. But if your case is the second one, then copy and paste the following code to your active theme's (or child theme if any) functions.php file:
add_filter('woocommerce_address_to_edit', 'cb_woocommerce_address_to_edit');
function cb_woocommerce_address_to_edit($address){
array_key_exists('billing_first_name', $address)?$address['billing_first_name']['custom_attributes'] = array('readonly'=>'readonly'):'';
array_key_exists('billing_last_name', $address)?$address['billing_last_name']['custom_attributes'] = array('readonly'=>'readonly'):'';
array_key_exists('billing_email', $address)?$address['billing_email']['custom_attributes'] = array('readonly'=>'readonly'):'';
array_key_exists('billing_email-2', $address)?$address['billing_email-2']['custom_attributes'] = array('readonly'=>'readonly'):'';
return $address;
}
The above code will make the following fields read-only:
Billing first name
Billing last name
Billing email address
Billing confirm email address
Array keys for other form fields on the same page are as follows:
billing_company
billing_country
billing_address_1
billing_address_2
billing_city
billing_state
billing_postcode
billing_phone
Additionally, you can make the read-only fields appear slightly faded out. So, add the following CSS to your theme's style.css
.woocommerce-address-fields input[readonly="readonly"]{
opacity: 0.5;
}

$checkout_fields['billing'][$key]['custom_attributes'] = array('readonly'=>'readonly');
this solves the problem

Answer 4

This one worked for me.

add_filter('woocommerce_billing_fields', 'my_woocommerce_billing_fields');
function my_woocommerce_billing_fields($fields)
{
$fields['billing_first_name']['custom_attributes'] = array('readonly'=>'readonly');
$fields['billing_last_name']['custom_attributes'] = array('readonly'=>'readonly');
return $fields;
}
