在 Woocommerce 中显示或隐藏两个结帐字段 [英] Show or Hide two checkout fields in Woocommerce

问题描述

在 Woocommerce 结帐表单中，我试图先隐藏 billing_city 和 billing_address_1 字段，然后在填写邮政编码和房屋号码字段后，其他字段(address_1 和城市)必须显示.

In Woocommerce checkout form im trying to hide billing_city and billing_address_1 fields first and after I fill the fields postcode and housenumber the other fields (address_1 and city) has to show.

这是脚本，但我不能很好地工作，我不知道我做错了什么:

This is the script, but I does not work well and I dont know what I do wrong:

?>
<script type="text/javascript">
    jQuery('input#billing_housenumber').change(function(){

        if (this.checked) {
            jQuery('#billing_city').fadeIn();
            jQuery('#billing_city input').val('');           
        } else {
            jQuery('#billing_city').fadeOut();
        }

    });
</script>
<?php

感谢任何帮助.

您的代码中存在一些错误、错误和遗漏.你也应该把它挂在一个函数中(或将它注册为一个外部文件).

There is some errors, mistakes and missing things in your code. Also you should hooked it in a function (or register it as an external file).

我在最后添加了一个添加计费housenumber"的函数；结帐字段(仅用于测试目的)...

I have added at the end a function that add the billing "housenumber" field in checkout (just for testing purpose)…

在下面的代码中，我使用了一些 CSS 内联样式来隐藏账单城市和 address_1 字段，并在它们具有额外的选择器类on"时显示它们.

In the code below I am using some CSS inline styles to hide the billing city and address_1 fields and to show them when they have an additional selector class "on".

这是一个钩子函数，仅在结帐时启用此代码:

Here is a hooked function that will enable this code in checkout only:

add_action( 'wp_footer', 'custom_checkout_script' );
function custom_checkout_script() {
    // Only checkout page
    if( ! ( is_checkout() && ! is_wc_endpoint_url() ) ) return;

    // CSS Styles (Hidding fields)
    ?>
    <style>
        #billing_city_field, #billing_address_1_field { display:none !important;}
        #billing_city_field.on ,#billing_address_1_field.on { display:block!important;}
    </style>
    <?php 
    // Jquery script
    ?>
    <script type="text/javascript">
    jQuery( function($){
        var a = 'input#billing_housenumber',
            b = 'input#billing_postcode',
            c = '#billing_city_field,#billing_address_1_field';

        // On start
        if( $(a).val() != '' && $(b).val() != '' && ! $(c).hasClass('on') ){
            $(c).css('display','none !important').addClass('on').show();
            console.log('start');
        }

        // On change: If housenumber and postcode fields are filled, we display other hidden fields
        $(a+','+b).on( 'change', function(){
            if ( $(a).val() != '' && $(b).val() != '' && ! $(c).hasClass('on') ) {
                $(c).css('display','none !important').addClass('on').show( 500 );
                console.log('change - in');
            } else if( ( $(a).val() == '' || $(b).val() == '' ) && $(c).hasClass('on') ) {
                $(c).hide( 200, function(){
                    $(c).removeClass('on').css('display','block')
                });
                console.log('change - out');
            }
        });
    });
    </script>
    <?php
}

代码位于活动子主题(或活动主题)的 function.php 文件中.经测试有效.

Code goes in function.php file of your active child theme (or active theme). Tested and works.

此代码已使用此临时附加代码进行测试，生成结帐housenumber"文本字段(仅用于测试目的):

This code has been tested with this temporary additional code, that generates the checkout "housenumber" text field (just for testing purpose):

// Add custom checkout field
add_action( 'woocommerce_billing_fields', 'my_custom_checkout_field' );
function my_custom_checkout_field( $fields ) {

     $fields['billing_housenumber'] = array(
        'class'     => array('form-row-wide'),
        'label'     => __('Housenumber ?'),
        'required'  => false,
        'clear'     => true
     );

     return $fields;
}

代码位于活动子主题(或活动主题)的 function.php 文件中.
