Question

对于我的生活，我无法使其工作（WP Codex的默认示例）。我创建了一个带有此代码的php文件并将其放在我的主题文件夹中，当我在网上访问该文件时，我得到一个空白页面，虚无... - 我错过了什么，我是否必须把它放在其他地方？非常感谢任何帮助。

  <?php
  $email = 'myemail@example.com';
  $exists = email_exists($email);
  if ( $exists )
  echo "That E-mail is registered to user number " . $exists;
  else
  echo "That E-mail doesn't belong to any registered users on this site";
  ?>

Answer 1

简单的回答，如果那是模板页面，请使用：

<?php
  $email = 'myemail@example.com';
  $exists = email_exists($email);
  if ( $exists )
  echo "That E-mail is registered to user number ";
  else
  echo "That E-mail doesn't belong to any registered users on this site";
  ?>

并确保您正确打开和关闭php标记。

但如果是来自tempalte页面以外的其他页面，请使用：

<?php
  require_once("../../../../wp-load.php");  //ADD THIS

  $email = 'myemail@example.com';
  $exists = email_exists($email);
  if ( $exists )
  echo "That E-mail is registered to user number ";
  else
  echo "That E-mail doesn't belong to any registered users on this site";
  ?>

根据页面位置在require_once（“../../../../ wp-load.php”）中添加或删除../。这肯定会对你有帮助。

Answer 2

尝试使用 正确路径在您的文件中添加 wp-load.php 。

<?php
  require_once("../../../wp-load.php");  //ADD THIS

  $email = 'myemail@example.com';
  $exists = email_exists($email);
  if ( $exists )
  echo "That E-mail is registered to user number " . $exists;
  else
  echo "That E-mail doesn't belong to any registered users on this site";
  ?>
