Php mail（）echo始终显示

Question

我正在尝试从我的网站上的联系表单发送邮件，当它成功发送时我想显示成功消息，但成功消息始终显示，是什么解决了这个问题？

<?php
    $bussiness = $_POST['contact[Business Name]'];
    $ownername = $_POST['ownername'];
    $buyername = $_POST['buyername'];
    $address = $_POST['address'];
    $city = $_POST['city'];
    $state = $_POST['state'];
    $zipcode = $_POST['zipcode'];
    $phone = $_POST['phone'];
    $email = $_POST['email'];
    $yib = $_POST['yib'];
    $nroe = $_POST['nroe'];
    $nol = $_POST['nol'];
    $taxid = $_POST['taxid'];
    $resalelicense = $_POST['resalelicense'];
    $productlines = $_POST['productlines'];
    $retailerlist = $_POST['retailerlist'];



    $formcontent=" From: $bussiness \n OwnerName: $ownername \n Buyer name: $buyername \n Address: $address \n City: $city \n State: $state \n Zip Code: $zipcode \n Phone: $phone \n Email: $email \n Years in bussiness: $yib \n Number of employees : $nroe \n Number of locations: $nol \n Tax ID: $taxid \n Resale license : $resalelicense \n Product lines: $productlines \n Retailer list: $retailerlist ";
    $recipient = "agonramizi@gmail.com";
    $subject = "Contact Form";
    $mailheader = "From: $email \r\n";
    if(mail($recipient, $subject, $formcontent, $mailheader)) {
        echo "Thank you, your message has been recieved!";
    }else {
        echo "Sorry, there was an error sending your message!";
    }
?>

我的html在下面，我想修复它以便它只在发送电子邮件后显示该消息，这是我的网站http://hip-products.rogsiteworks.com/contact.php

谢谢
