 <form class="form" id="regisForm" name="regisForm"  method="post">
<span id="check_email"></span>
  <input type="email"  id="email1" name="email1"   >
<span id="check_email"></span>
  <input type="email"  id="email2" name="email2"   >
<span id="check_email"></span>
  <input type="email"  id="email3" name="email3"   >
<span id="check_email"></span>
  <input type="email"  id="email4" name="email4"   >
<span id="check_email"></span>
  <input type="email"  id="email5" name="email5"   >
<span id="check_email"></span>
  <input type="email"  id="email6" name="emai6l"   >
</form>

// **** Check Email **** //
    if(isset($_POST["email"])) {
        $value = trim($_POST["email"]);
        $Records = new Records();
        echo $Records->searchDate($value);
    }


public function searchDate($value) {
        try {
            $stmt = $conn->prepare("SELECT `regis_mail` FROM `register` WHERE `regis_mail` = :value");
            $stmt->bindParam(':value', $value, PDO::PARAM_STR);
            $stmt->execute();
            $count = $stmt->rowCount();
            $result = 0;
            if ($count > 0) {
                $result = "Found";
            } else {
                $result = "Not Found";
            }
            return $result;
        } catch (PDOException $e) {
            echo 'Connection Failed ' . $e->getMessage();
        }
    }

$(document).ready(function(){
    $('#email').blur(function(){
       var value = $(this).val(); 
       liveCheckEmail(value);
    });
 });
 function liveCheckEmail(val) {
     $.post('check_email.php',{'email':val}, function(data){
         if(data == "Found") {
             $('#check_email').html("<span style='color:red; font-weight:bold;'>Email นี้มีผู้ใช้ในระบบแล้ว</span>");
         } else {
             $('#check_email').html("<span style='color:green; font-weight:bold;'>Email นี้สามารถใช้ได้ </span>");
         }
     }).fail(function(xhr, ajaxOptions, throwError) {
     alert(throwError);
     });
 }
