php echo wordpress用户元数据

Question

在我的网站上，当用户注册时，有一个选项可以从一个额外的选项中选择，该选项会将他们的帐户与一个非营利性组织联系起来。一旦用户注册并查看网站的特定页面，我希望该网站是为他们量身定做使用php，抓住他们的元信息。为此，我将回显一个按钮，该按钮根据注册时选择的元值来定制前端。

如果它们没有元键，则不会显示任何内容。

这是我的代码尝试，但不起作用！

    <?php global $current_user;
get_currentuserinfo(); //wordpress global variable to fetch logged in user info
$userID = $current_user->ID; //logged in user's ID
$havemeta1 = get_user_meta($userID,'nch',true); //stores the value of logged in user's meta data for 'National Coalition for the homeless'
$havemeta2 = get_user_meta($userID,'rotary-international',true); //stores the value of logged in user's meta data for 'Rotary International'
$havemeta3 = get_user_meta($userID,'khan-academy',true); //stores the value of logged in user's meta data for 'Khan Academy'
$havemeta4 = get_user_meta($userID,'wwf',true); //stores the value of logged in user's meta data for 'World Wildlife Fund (WWF)'
$havemeta5 = get_user_meta($userID,'bcrf',true); //stores the value of logged in user's meta data for 'The Breast Cancer Research Foundation'
?>

<!--add if statement to figure out what button to show to logged in user-->

<?php if ($havemeta1) { ?>
   <div <p>nch</p> class="Button1"></div>
<?php } elseif ($havemeta2) { ?>
   <div <p>rotary-international</p>class="Button2"></div>
<?php } elseif ($havemeta3) { ?>
   <div <p>khan-academy</p>class="Button3"></div>
<?php } elseif ($havemeta4) { ?>
   <div <p>wwf</p>class="Button4"></div>
<?php } elseif ($havemeta5) { ?>
   <div <p>bcrf</p>class="Button5"></div>
<?php } else { ?>
   <div><p>None - No Matching Affiliation</p></div>
<?php }?>

这让我可以看到从属变量为用户拉出了什么，结果是：'User Affiliation: khan-academy‘。

<?php global $current_user;
      get_currentuserinfo();

      echo 'User Affiliation: ' . $current_user->affiliation . "\n";
?>

Answer 1

你能传递一个会话变量，即$_ session 'havemeta5'；

Answer 2

get_user_meta设置错误。试试这个：

$havemeta1 = get_user_meta( $userID, 'nch', true );

...and等等。您需要将$userID作为get_user_meta()的第一个参数传递，而不是$affiliation。

更新

如果您的用户meta是'affiliation‘(允许您调用$current_ user ->affiliation)，您可以这样做：

<?php
global $current_user;
get_currentuserinfo();
$userID = $current_user->ID;
$affiliation = get_user_meta( $userID, 'affiliation', false );
$affiliation = $affiliation[0];
if( 'nch' == $affiliation ){
  print '<div class="Button1"><p>nch</p></div>';
} elseif( 'rotary-international' == $affiliation ){
  print '<div class="Button2"><p>Rotary International</p></div>';
} elseif( 'khan-academy' == $affiliation ){
  print '<div class="Button3"><p>Khan Academy</p></div>';
} elseif( 'wwf' == $affiliation ){
  print '<div class="Button4"><p>wwf</p></div>';
} elseif( 'bcrf' == $affiliation ){
  print '<div class="Button5"><p>bcrf</p></div>';
} else {
  print '<div><p>None - no matching affiliation</p></div>';
  print '<div>User ID: '.$userID.', Affiliation: '.$affiliation.'</div>';
}
