在WooCommerce中为特定国家/地区选择结帐电话字段

I have to display phone as required (mandatory) only if a certain country is selected in WooCommerce checkout screen.

What is the validation rule to check the selected country in real time?

I have tried the following code, which is working for making phone non required:

add_filter( 'woocommerce_billing_fields', 'wc_npr_filter_phone', 10, 1 );
function wc_npr_filter_phone( $address_fields ) {
    $address_fields['billing_phone']['required'] = false;

    return $address_fields;
}

只有在WooCommerce结帐屏幕中选择了某个国家/地区时,才需要显示电话(必填)。

实时检查所选国家/地区的验证规则是什么?

我尝试过以下代码,该代码适用于非手机操作 必需:

  add_filter('woocommerce_billing_fields','wc_npr_filter_phone',10,1); 
 
function wc_npr_filter_phone($ address_fields){
 $ address_fields ['billing_phone'] ['  required'] = false; 
 
返回$ address_fields; 
}

    You mostly need to use javascript for real time events or live events on client side… The code below is mostly using jQuery and a bit of PHP, to make the billing phone required only when customer select specific countries:

    // Making the billing phone field not required (by default)
    add_filter( 'woocommerce_billing_fields', 'filter_billing_phone_field', 10, 1 );
    function filter_billing_phone_field( $fields ) {
        $fields['billing_phone']['required'] = false;
        return $fields;
    }
    
    // Real time country selection actions
    add_action( 'woocommerce_after_order_notes', 'custom_checkout_scripts_and_fields', 10, 1 );
    function custom_checkout_scripts_and_fields( $checkout ) {
        $required = esc_attr__( 'required', 'woocommerce' );
    
        // HERE set the countries codes (2 capital letters) in this array:
        $countries = array( 'UK', 'BE', 'GE', 'IT', 'ES' );
    
        // Hidden field for the phone number validation
        echo '<input type="hidden"  name="billing_phone_check" id="billing_phone_check" value="0">';
        $countries_str = "'".implode( "', '", $countries )."'"; // Formatting countries for jQuery
        ?>
        <script type="text/javascript">
            (function($){
                var required = '<abbr class="required" title="<?php echo $required; ?>">*</abbr>',
                    countries = [<?php echo $countries_str; ?>],
                    location = $('#billing_country option:selected').val(),
                    phoneCheck = 'input#billing_phone_check';
    
                function actionRequire( actionToDo='yes', selector='' ){
                    if ( actionToDo == 'yes' ) {
                        $(selector).addClass("validate-required");
                        $(selector+' label').append(required);
                    } else {
                        $(selector).removeClass("validate-required");
                        $(selector+' label > .required').remove();
                    }
                    $(selector).removeClass("woocommerce-validated");
                    $(selector).removeClass("woocommerce-invalid woocommerce-invalid-required-field");
                }
    
                // Default value when loading
                actionRequire( 'no','#billing_phone_field' );
                if( $.inArray( location, countries ) >= 0  && $(phoneCheck).val() == '0' ){
                    actionRequire( 'yes','#billing_phone_field' );
                    $(phoneCheck).val('1');
                }
    
                // Live value
                $( 'form.checkout' ).on( 'change', '#billing_country', function(){
                    var location = $('#billing_country option:selected').val();
                    if ( $.inArray( location, countries ) >= 0 && $(phoneCheck).val() == 0 ) {
                        actionRequire( 'yes','#billing_phone_field' );
                        $(phoneCheck).val('1');
                    } else if ( $(phoneCheck).val() == 1 ) {
                        actionRequire( 'no','#billing_phone_field' );
                        $(phoneCheck).val('0');
                    }
                });
           })(jQuery);
            </script>
        <?php
    }
    
    // Phone number validation, when it's visible
    add_action('woocommerce_checkout_process', 'billing_phone_field_process');
    function billing_phone_field_process() {
        // Check if set, if its not set add an error.
        if ( ! $_POST['billing_phone'] && $_POST['billing_phone_check'] == '1' )
            wc_add_notice( __( 'Please enter a number phone.' ), 'error' );
    }
    

    Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

    Tested and works.
