Answer 1

1. 複製checkout/payment-method.php文件到您的主題目錄woocommerce文件夾。即你的主題/ woocommerce /結帳/付款method.php

2. 變化的內容裏標籤用下面的代碼：

<li class="wc_payment_method payment_method_<?php echo $gateway->id; ?>"> 
<input id="payment_method_<?php echo $gateway->id; ?>" type="radio" class="input-radio" name="payment_method" value="<?php echo esc_attr($gateway->id); ?>" <?php checked($gateway->chosen, true); ?> data-order_button_text="<?php echo esc_attr($gateway->order_button_text); ?>" /> 
<label for="payment_method_<?php echo $gateway->id; ?>"> 
<?php echo $gateway->get_title(); ?> <?php echo $gateway->get_icon(); ?> 
</label> 
<?php if (($gateway->has_fields() || $gateway->get_description()) && $gateway->id != "cod") : ?> 
<div class="payment_box payment_method_<?php echo $gateway->id; ?>" <?php if (! $gateway->chosen) : ?>style="display:none;"<?php endif; ?>> 
<?php $gateway->payment_fields(); ?> 
</div> 
<?php endif; ?> 
<?php if ($gateway->id == "cod") : ?> 
<div class="payment_box payment_method_<?php echo $gateway->id; ?>" <?php if (! $gateway->chosen) : ?>style="display:none;"<?php endif; ?>> 
<?php $gateway->payment_fields(); ?> 
<label>Custom Field</label> 
<input type="text" name='cod_custom_field'> 
</div> 
<?php endif; ?> 
</li> 

添加以下代碼YOUT主題functions.php文件

/** 
* 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['cod_custom_field'])) { 
     update_post_meta($order_id, 'COD Custom Field', sanitize_text_field($_POST['cod_custom_field'])); 
    } 
} 

/** 
* Display field value on the order edit page 
*/ 
add_action('woocommerce_admin_order_data_after_billing_address', 'my_custom_checkout_field_display_admin_order_meta', 10, 1); 

function my_custom_checkout_field_display_admin_order_meta($order){ 
    echo '<p><strong>'.__('COD Custom Field').':</strong> ' . get_post_meta($order->id, 'COD Custom Field', true) . '</p>'; 
} 

就是這樣。希望這個幫助。
