在 WooCommerce 3 中重新排序结帐字段

Question

我正在尝试重新排序在woocommerce_checkout_init过滤器的帮助下添加的 2 个自定义结帐字段，只是当我将woocommerce_checkout_fields过滤器应用于重新排序字段时，它无法识别它们，它们是null.
我认为这是因为过滤器woocommerce_checkout_init追求woocommerce_checkout_fields.

我该如何解决这个问题？

这是我的代码：

add_action( 'woocommerce_checkout_init', 'wc_add_confirm_email_checkout', 10, 2 );
function wc_add_confirm_email_checkout( $checkout ) {
    $checkout->checkout_fields['billing']['billing_email2'] = array(
        'type'              => 'text',
        'label'             => __( 'Confirm Email Address', 'woocommerce' ),
        'required'          => true,
        'placeholder'       => _x( 'Confirm Email Address', 'placeholder', 'woocommerce' )
    );
}
add_action( 'woocommerce_checkout_init', 'wc_add_confirm_password_checkout', 10, 2 );
function wc_add_confirm_password_checkout( $checkout ) {
    //var_dump($checkout->checkout_fields);
    if ( get_option( 'woocommerce_registration_generate_password' ) == 'no' ) {
        $checkout->checkout_fields['account']['account_password2'] = array(
            'type'              => 'password',
            'label'             => __( 'Confirm password', 'woocommerce' ),
            'required'          => true,
            'placeholder'       => _x( 'Confirm Password', 'placeholder', 'woocommerce' )
        );
    }
}

add_filter('woocommerce_checkout_fields','reorder_woo_fields');
function reorder_woo_fields($fields) {
    $fields2['billing']['billing_first_name'] = $fields['billing']['billing_first_name'];
    $fields2['billing']['billing_last_name'] = $fields['billing']['billing_last_name'];
    $fields2['billing']['billingooglg_email'] = $fields['billing']['billing_email'];
    $fields2['billing']['billing_email2'] = $fields['billing']['billing_email2'];
    $fields2['billing']['account_password'] = $fields['account']['account_password'];
    $fields2['billing']['account_password2'] = $fields['account']['account_password2'];
    $fields2['billing']['billing_address_1'] = $fields['billing']['billing_address_1'];
    $fields2['billing']['billing_postcode'] = $fields['billing']['billing_postcode'];
    var_dump($fields2);
    //return $fields2;
}

对于 WooCommerce 3+ （更新）：

由于WooCommerce 3.0 结帐字段发生了一些变化，因此无法像以前那样对字段重新排序。

有一个新的'priority'参数处理字段 order，结帐字段和我的帐户字段也是如此。

这是 WooCommerce 3+ 的全功能示例：

// REORDERING CHECKOUT BILLING FIELDS (WOOCOMMERCE 3+)
add_filter( "woocommerce_checkout_fields", "reordering_checkout_fields", 15, 1 );
function reordering_checkout_fields( $fields ) {

    ## ---- 1. REORDERING BILLING FIELDS ---- ##

    // Set the order of the fields
    $billing_order = array(
        'billing_first_name',
        'billing_last_name',
        'billing_email',
        'billing_phone',
        'billing_company',
        'billing_address_1',
        'billing_address_2',
        'billing_postcode',
        'billing_city',
        'billing_state',
        'billing_country'
    );

    $count = 0;
    $priority = 10;

    // Updating the 'priority' argument
    foreach($billing_order as $field_name){
        $count++;
        $fields['billing'][$field_name]['priority'] = $count * $priority;
    }

    ## ---- 2. CHANGING SOME CLASSES FOR BILLING FIELDS ---- ##

    $fields['billing']['billing_email']['class'] = array('form-row-first');
    $fields['billing']['billing_phone']['class'] = array('form-row-last');

    $fields['billing']['billing_postcode']['class'] = array('form-row-first');
    $fields['billing']['billing_city']['class'] = array('form-row-last');
    
    ## ---- RETURN THE BILLING FIELDS CUSTOMIZED ---- ##

    return $fields;
}

在 WooCommerce 3 之前

我不完全确定，但是您有一些事情不能做，例如将帐单字段与帐户字段合并。如果你想这样做会比你在这里尝试做的要复杂得多。在这种情况下，您将需要重写/创建一些结帐模板......

另一件事是billing_email和billing_phone与一起共享相同的线'class' => 'form-row-first'和'class' => 'form-row-last'。如果没有这个类定义'class' => 'form-row-wide'...所以你将需要重写这些'class'了。

之后你就不需要使用'woocommerce_checkout_init'钩子了……
你仍然可以使用'woocommerce_checkout_fields'.
您也可以通过这种方式将所有这些合并到一个函数中：

/*
 * Creating, overriding and reordering custom fields.
 */
add_filter( "woocommerce_checkout_fields", "custom_override_checkout_fields", 11, 1 );
function custom_override_checkout_fields( $fields ) {

    // Creating 'billing_email2' field
    $fields['billing']['billing_email2'] = array(
        'type'          => 'text',
        'label'         => __( 'Confirm Email Address', 'woocommerce' ),
        'placeholder'   => _x( 'Confirm Email Address', 'placeholder', 'woocommerce' ),
        'required'      => true,
        'class'         => array('form-row-last'),
        'clear'         => true
    );

    // =======> I don't really know if you need this one  <========
    // it already exist (see in first reference link at bottom).

    // Creating 'account_password2' field 
    if ( get_option( 'woocommerce_registration_generate_password' ) == 'no' ) {
        $fields['account']['account_password2'] = array(
            'type'          => 'password',
            'label'         => __( 'Confirm password', 'woocommerce' ),
            'placeholder'   => _x( 'Confirm Password', 'placeholder', 'woocommerce' ),
            'required'      => true,
            'class'         => array('form-row-wide') //,
            // 'clear'         => true
        );
    }

    // Overriding existing billing_phone field 'class' property 
    $fields['billing']['billing_phone']['class'] = array('form-row-wide');


    // Reordering billing fields
    $order = array(
        "billing_first_name",
        "billing_last_name",
        "billing_email",
        "billing_email2",
        "billing_phone",
        "billing_company",
        "billing_address_1",
        "billing_address_2",
        "billing_postcode",
        "billing_country"
    );

    foreach($order as $field)
    {
        $ordered_fields[$field] = $fields["billing"][$field];
    }

    $fields["billing"] = $ordered_fields;

    return $fields;
}

代码位于活动子主题（或主题）的 function.php 文件或任何插件文件中。

正如我之前所说，我认为您不能将帐单字段与帐户字段合并。
至于'account_password2'如果你指的官方文件已经存在（参见下面的第一参考链接），你可能不需要创建它。您必须对此进行测试并对其进行微调。但这是做到这一点的方法。
