Php 在前端使用WPAlchemy重复字段

我正在使用WPAlchemy为我的自定义帖子类型创建元数据

我的一个自定义帖子类型，vendor，在WPAlchemy中声明为$vendor\u mb，前缀为\u vendor，并具有以下元字段

• 地址
• 国家
• Zipcode
• 网站

---

• 联系人因为WP Alchemy将数据存储为序列化数组，所以您必须做一些奇怪的事情来准备插入重复字段
  本文详细介绍了您需要执行的操作：
  简而言之，您需要插入一个序列化数组，然后分别插入每个元值，如下所示：

   //add a serialised array for wpalchemy to work
  $data = array('reviews_what_we_did','reviews_star_rating','reviews_name','reviews_email','reviews_staff_member');
  $str = $data;
  update_post_meta( $pid, '_single_reviews_meta_fields', $str );
  
  //update the individual fields
  add_post_meta($pid, 'reviews_what_we_did', $service);
  add_post_meta($pid, 'reviews_star_rating', $rating);
  add_post_meta($pid, 'reviews_name', $name);
  add_post_meta($pid, 'reviews_email', $email);
  add_post_meta($pid, 'reviews_staff_member', $staff);
  

  $fields = array('address', 'country', 'zipcode', 'website', 'contacts');
  $str = $fields;
  update_post_meta( $postid, '_contact_meta_fields', $str );
  
  $contactfields = array(
  array(
  'department' => $departmentvalue,
  'firstname' => $firstnamevalue,
  'lastname'  => $lastnamevalue,
  'title' => $titlevalue,  // etc. - add all of your fields to the array
  )
  );
  
  add_post_meta($postid, 'address', $addressvalue); // do this for each of your non-repeating fields
  add_post_meta($postid, 'contacts', $contactfields); // this adds the repeating fields
  

  但是，此代码段仅适用于普通字段，不适用于重复字段。重复的字段增加了另一层复杂性
  本文介绍如何将数据插入重复字段：
  在您的情况下，您需要执行以下操作：

   //add a serialised array for wpalchemy to work
  $data = array('reviews_what_we_did','reviews_star_rating','reviews_name','reviews_email','reviews_staff_member');
  $str = $data;
  update_post_meta( $pid, '_single_reviews_meta_fields', $str );
  
  //update the individual fields
  add_post_meta($pid, 'reviews_what_we_did', $service);
  add_post_meta($pid, 'reviews_star_rating', $rating);
  add_post_meta($pid, 'reviews_name', $name);
  add_post_meta($pid, 'reviews_email', $email);
  add_post_meta($pid, 'reviews_staff_member', $staff);
  

  $fields = array('address', 'country', 'zipcode', 'website', 'contacts');
  $str = $fields;
  update_post_meta( $postid, '_contact_meta_fields', $str );
  
  $contactfields = array(
  array(
  'department' => $departmentvalue,
  'firstname' => $firstnamevalue,
  'lastname'  => $lastnamevalue,
  'title' => $titlevalue,  // etc. - add all of your fields to the array
  )
  );
  
  add_post_meta($postid, 'address', $addressvalue); // do this for each of your non-repeating fields
  add_post_meta($postid, 'contacts', $contactfields); // this adds the repeating fields
  

  打印post meta非常有用，这样您就可以看到WPAlchemy如何创建序列化数组以及每个meta值
