我在WordPress中通过创建短代码使用下面的联系人代码。当我提交表单时，它会显示成功消息，但收件箱中没有收到任何电子邮件或垃圾邮件。谁能帮忙吗。
function contactform_func( $atts ) {
$atts = shortcode_atts( array(
\'to_email\' => \'\',
\'title\' => \'Contact enquiry - \'.get_bloginfo(\'url\'),
), $atts );
$cform = "<div class=\\"main-form-area\\" id=\\"contactform_main\\">";
$cerr = array();
if( isset($_POST[\'c_submit\']) && $_POST[\'c_submit\']==\'Submit\' ){
$name = trim( $_POST[\'c_name\'] );
$email = trim( $_POST[\'c_email\'] );
$phone = trim( $_POST[\'c_phone\'] );
$website = trim( $_POST[\'c_website\'] );
$comments = trim( $_POST[\'c_comments\'] );
$captcha = trim( $_POST[\'c_captcha\'] );
$captcha_cnf = trim( $_POST[\'c_captcha_confirm\'] );
if( !$name )
$cerr[\'name\'] = \'Please enter your name.\';
if( ! filter_var($email, FILTER_VALIDATE_EMAIL) )
$cerr[\'email\'] = \'Please enter a valid email.\';
if( !$phone )
$cerr[\'phone\'] = \'Please enter your phone number.\';
if( !$comments )
$cerr[\'comments\'] = \'Please enter your question / comments.\';
if( !$captcha || (md5($captcha) != $captcha_cnf) )
$cerr[\'captcha\'] = \'Please enter the correct answer.\';
if( count($cerr) == 0 ){
$subject = $atts[\'title\'];
$headers = "From: ".$name." <" . strip_tags($email) . ">\\r\\n";
$headers .= "MIME-Version: 1.0\\r\\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\\r\\n";
