无法接收电子邮件

Question

我正在尝试在<a>代码内发送电子邮件。但目的地未收到该电子邮件。

发件人

<a href='http://localhost/Trying/search_cus.php?emailFromCus=$email'>Search Medicin</a>

接收机

`

<?php 

    if(isset($_POST['emailFromCus'])){
        $con = mysqli_connect("localhost", "root", "") or 
        die(mysqli_error($con));
        mysqli_select_db($con,"Ajmal") or die(mysqli_error($con));

        $cusEmail=$con->real_escape_string($_GET['emailFromCus']);

        echo "<script>alert($cusEmail);</script>";
    }
    else{
         echo "error";
    }

?>

`

它将进入其他条件......要做什么？
