我试图在比赛的第一个条目上创建一个新的帖子，然后在后续条目上更新现有条目，这样我可以每个条目有一个帖子，但允许多个条目。

问题是，如果你参加比赛（见下面的链接），它将创建一个新的帖子（它有效）。然后，如果你刷新页面，它会说你需要等待X分钟（在这种情况下是5分钟），然后才能再次输入（它可以工作）。

但是，如果您返回到条目页面，使用相同的电子邮件和相同的zip，或相同的电子邮件和不同的zip再次输入，它有时会做正确的事情并更新帖子条目，但有时会创建一个新条目（新帖子），而不是更新现有条目。

我需要帮助让它做正确的事情。如果条目存在，则更新该条目；如果条目不存在，则创建一个新条目。

代码：

// SYSTEM VARS

$currentTime    = time();
$entryCode      = md5($entryEmail);

// ENTRY DATA
$entryEmail = sanitize_email($_POST[\'entryEmail\']);
$entryZip   = sanitize_text_field($_POST[\'entryZip\']);
$entryIP    = $_POST[\'entryIP\'];



// CREATE ENTRY


function createEntry($cee, $cez, $ceip, $cec) {

$newEntry = wp_insert_post(

        array(
            \'comment_status\'    =>  \'closed\',
