Woocommerce - 如果两个product_ids中的一个在结账时在购物车中，添加表单字段并显示/隐藏div

Question

这就是它。我的php-fu仍然很弱，而且我对woocommerce还很新。

我需要创建一个脚本，用于在结帐页面上检查购物车中的两个特定产品id，如果有，请添加一个“paypal电子邮件地址”文本字段和一个“接收时事通讯？复选框，以及用另一个隐藏的div替换我在“form-shipping.php”模板中创建的div。

令人惊讶的是，到目前为止，我的研究甚至没有在结账页面成功确认购物车中的product_id，这似乎是一个相当普遍的需求。在这一点上，我认为这是一个巨大的胜利。

任何建议，指导或完成此目标的线索将不胜感激。

这里是我一直使用的代码，试图从https://wordimpress.com/create-conditional-checkout-fields-woocommerce/适应：

<?php 
add_action('woocommerce_before_checkout_billing_form', 'aym_custom_checkout_field'); 

function aym_custom_checkout_field($checkout) { 

    //Check if Product in Cart 
    $prod_in_cart_17563 = aym_is_conditional_product_in_cart_17563(17563); 
    $prod_in_cart_17558 = aym_is_conditional_product_in_cart_17558(17558); 

    if ($prod_in_cart_17563 === true || $prod_in_cart_17558 === true) { 


     //Prod is in cart so hide div 
     echo '<script type="text/javascript">$(".checkout_promo_content").css("display", "none")</script>'; 
     echo '<script type="text/javascript">$(".checkout_promo_aff_content").css("display", "block")</script>'; 

     //and add additional fields 
     echo '<div id="email_paypal"><h3>' . __('Paypal Email Address') . '</h3><p style="margin: 0 0 8px;">Please enter the email address you use for Paypal</p>'; 

     woocommerce_form_field('pp_email_textbox', array(
     'type' => 'text', 
     'class' => array('paypal-email form-row-wide'), 
     'label' => __('Paypal Email Address'), 
     ), $checkout->get_value('pp_email_textbox')); 


     echo '<h3>' . __('Ambassador Terms and Conditions') . '</h3><p style="margin: 0 0 8px;">Please accept the <a href="http://www.acceleratingyoungminds.com/ambassador-terms-conditions/">Ambassaor Terms and Conditions</a></p>'; 

     woocommerce_form_field('amb_terms_checkbox', array(
     'type' => 'checkbox', 
     'class' => array('amb_terms-checkbox form-row-wide'), 
     'label' => __('I accept Ambassador terms and Conditions'), 
     ), $checkout->get_value('amb_terms_checkbox')); 


     echo '<h3>' . __('Subscribe for Ambassador Mailing List') . '</h3><p style="margin: 0 0 8px;">Would you like to subscribe for welcome emails and important information</p>'; 

     woocommerce_form_field('amb_sub_checkbox', array(
     'type' => 'checkbox', 
     'class' => array('amb_sub_checkbox form-row-wide'), 
     'label' => __('I would like to subscribe to the Ambassador Newsletter'), 
     ), $checkout->get_value('amb_sub_checkbox')); 

     echo '</div>'; 
    } 

} 


?>

首先新秀的举动，我失败了，甚至定义了两种产品（aym_is_conditional_product_in_cart_17563等）的功能。其次，我错误地称JQuery为WordPress。第三，我在add_action中使用了错误的钩子。第四，我最初过早并且急于发布这整个事情。我给我的家人带来了羞耻。以下代码按预期工作。希望它可以帮助有类似问题的人。

//AMBASSADOR CUSTOM CHECKOUT FIELDS, CONTENT 
add_action('woocommerce_after_checkout_billing_form', 'aym_custom_checkout_field'); 

function aym_custom_checkout_field($checkout) { 

    //Check if Product in Cart 
    $prod_in_cart_17563 = aym_is_conditional_product_in_cart_17563(17563); 
    $prod_in_cart_17558 = aym_is_conditional_product_in_cart_17558(17558); 

    if ($prod_in_cart_17563 === true || $prod_in_cart_17558 === true) { 


     //Prod is in cart so hide div 
     echo '<script type="text/javascript"> 

     jQuery(function($) { 
      $(window).load(function(){ 
       console.log("hidden!"); 
       $(".check-promo-content").css("display", "none"); 
      }); 
     }); 

     </script>'; 

     echo '<script type="text/javascript">

      console.log("shown!"); 
      $(".checkout_promo_aff_content").css("display", "block"); 
     });</script>'; 

     //and add additional fields 
     echo '<div id="email_paypal"><h3>' . __('Paypal Email Address') . '</h3><p style="margin: 0 0 8px;">Please enter the email address you use for Paypal</p>';
