我一直在尝试使用wp\\U mail从插件中发送电子邮件。我使用的代码如下。

function add_page_content_Send_Feed(){
    echo "<h2>Send your feed via email</h2>";


    echo "<form id=\'post\' action=\'\' method=\'POST\'>";
    echo "<input type=\'submit\' name=\'send_feed\' value=\'Send my feed\' id=\'submit\';\'/>";
    echo "</form>";

    // Example using the array form of $headers
    // assumes $to, $subject, $message have already been defined earlier...

    $headers[] = \'From: UltraIT <[email protected]>\';
    $headers[] = \'Cc: John Q Codex <[email protected]>\';
    $headers[] = \'Cc: [email protected]\'; // note you can just use a simple email address

    $to = \'[email protected]\';
    $subject = \'TESTING\';
    $message = \'hello\'; 

    if(isset($_POST[\'send_feed\'])) {
        wp_mail( $to, $subject, $message, $headers);
    }

}
