WooCommerce checkout fields: using str_replace on a post meta field value - php

Question

I need to replace some character in my custom checkout field.
this is the whole code of my custom checkout field , (maybe we could use str_replace here)
/* Add the field to the checkout */
add_action( 'woocommerce_after_checkout_billing_form', 'my_custom_checkout_field' );
function my_custom_checkout_field( $checkout ) {
echo '<div id="my_custom_checkout_field">';
woocommerce_form_field( 'phone_sabet', array(
'type' => 'tel',
'required' => true,
'clear' => true,
'class' => array('my-field-class form-row-first'),
'label' => __(''),
'placeholder' => __(''),
'description' => '',
), $checkout->get_value(('phone_sabet')));
echo '</div>';
}
this is the part of code when the custom field going to update
/* Update the order meta with field value */
add_action( 'woocommerce_checkout_update_order_meta','my_custom_checkout_field_update_order_meta' );
function my_custom_checkout_field_update_order_meta( $order_id ) {
if ( ! empty( $_POST['phone_sabet'] ) ) {
update_post_meta( $order_id, 'Phone', sanitize_text_field( $_POST['phone_sabet'] ) );
}
}
i tired to use str_replace and change it to below but no luck.
add_action( 'woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta' );
function my_custom_checkout_field_update_order_meta( $order_id ) {
if ( ! empty( $_POST['phone_sabet'] ) ) {
update_post_meta( $order_id, 'Phone', sanitize_text_field( $_POST['phone_sabet'] ) );
$getMeta = get_post_meta( get_the_ID(), 'Phone', true);
$newMeta = str_replace(array('۱'), '1', $getMeta);
update_post_meta(get_the_ID(), 'Phone', $newMeta);
}
}
and this is the part of when checkout field going to process. its okay if we could done it with str_replace here.
/* Process the checkout */
add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');
function my_custom_checkout_field_process() {
if ( $_POST['phone_sabet'] )
// do something
}

The correct hook is woocommerce_checkout_update_order_meta, so you could try this:
## Save the order meta with custom field value
add_action( 'woocommerce_checkout_update_order_meta', 'custom_update_order_meta' );
function custom_update_order_meta( $order_id ) {
if ( ! empty( $_POST['phone_sabet'] ) ) {
// Replace before saving translating )
$phone_sabet = str_replace( array('۱'), array('1'), $_POST['phone_sabet'] );
update_post_meta( $order_id, 'phone', sanitize_text_field( $phone_sabet ) );
}
}
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
Tested and works
