PHP 不从自定义字段中提取元数据

Question

我正在开发一个允许通过自定义字段输入然后将其输出到不同页面的 WordPress 网站。当用户注册时，他们会通过向某人发送邀请 link 来请求某人成为 "trusted member"，邀请 link 具有唯一标识符，当受邀者注册时，UID 将作为元数据存储在他们的帐户中。

然后使用（或应该）使用此元数据在页面上创建一个部分，显示有关邀请他们的人的一些信息。

（长话短说，该网站是一个纪念型网站，有人可以将他们的遗愿上传到该网站。受信任的验证者是指定的人，将其成员死亡通知网站所有者，以便网站所有者可以按照他们的意愿行事.)

基本上，我要做的是从用户帐户中获取元数据，然后使用它来获取人名。

我已将此函数的完整代码添加到代码笔中：https://codepen.io/david-wdc/pen/LYEoOXe

Answer 1

我已经设法解决了这个问题，

我试图将整个对象传递给一个函数，但它只需要对象中的一个元素。

The new code is below if anybody comes across something similar!

add_shortcode('trusted_verifier_dashboard', 'trusted_verifier_dashboard');

function trusted_verifier_dashboard(){

ob_start();
$user_id = get_current_user_id();

$current_user = wp_get_current_user();

if ( in_array( 'trusted', (array) $current_user->roles ) ) {
//The user has the "trusted" role

//$unique_list = get_user_meta( $user_id, 'tv_member' );
$id_list = get_user_meta( $user_id, 'tv_uid' );
//$row_list = get_user_meta( $user_id, 'tv_row' );

//var_dump($unique_list);
//var_dump($id_list);
//var_dump($row_list);

 //foreach($unique_list as $row => $value){
     //echo ($value);
 //}

 $current_user_id = get_current_user_id();
 //echo "Current User Id: "; print_r ($current_user_id);



 foreach($id_list as $row => $array) {

          $member_id = $array;
          $unique = get_user_meta($current_user_id, 'tv_member', true);
          //$row = get_user_meta($current_user_id, 'tv_row', true);
          $image = '';
          $unique_lookup = get_user_meta($member_id, 'trusted_verifiers_'.$row.'_tv_unique', true);
          $fname = get_user_meta($member_id, 'first_name', true);
          $sname = get_user_meta($member_id, 'last_name', true);
          $city = get_user_meta($member_id, 'billing_city', true);
          $photo = get_user_meta($member_id, '_memorial_photo_0_upload_image', true);

          /*echo "<br>member_id: "; print_r ($array); echo "<br>unique key: ";print_r ($unique); echo "<br>unique lookup: "; print_r ($unique_lookup); echo "<br>row: "; print_r ($row);*/

          if ($unique == $unique_lookup){
