複数のチェックボックスの値を保持している問題があります。

Question

複数のチェックボックスの配列の値を保持できません。このサイトを見て、私の答えを適用しましたが、何らかの理由でチェックされた値を保持していません。 **ここに私のPHPは*

 <?php 

    // start session 
    session_start(); 

    // i user is not log in redirect back to index 
    if(!isset($_SESSION['user_type'])){ 
     header('Location: index.php'); 
    } 

    // include data based connection config 
    include_once('include/connection.php'); 

    // incluude header ttile page 
    $title = "Edit User Profile"; 

    // set user session variables 
    $userId = $_SESSION['user_id']; 
    //$userName = $_SESSION['user_name']; 
    $temp = $_SESSION['user_name']; 

    //$competency = ""; 
    // if user update the data 
     if(isset($_POST['update'])){ 

     // define post variable 
    $firstname = trim($_POST['firstname']); 
    $lastname = trim($_POST['lastname']); 
    $email = trim($_POST['email']); 
    $user_name = trim($_POST['user_name']); 
    $profession = trim($_POST['profession']); 
    $phone = trim($_POST['phone']); 
    $hobbies = trim($_POST['hobbies']); 
    $skills = trim($_POST['skills']); 
    $competency = implode(', ', $_POST['competency']); 
    $postcode = trim($_POST['postcode']); 
    $address = trim($_POST['address']); 
    $bio = trim($_POST['bio']); 
    $dob = trim($_POST['dob']); 
    $gender = trim($_POST['gender']); 
    $country = trim($_POST['country']); 


      // ************* UPDATE PROFILE INFORMATION ************************// 
      if(!($stmt = $con->prepare("UPDATE user SET firstname = ?, lastname = ?, skills = ?, competency = ?, profession = ?, 
      user_name = ?, phone = ?, address = ?, email = ?, bio = ?, 
      gender = ?, dob = ?, country = ? WHERE id = ?"))) { 
       echo "Prepare failed: (" . $con->errno . ")" . $con->error; 
      } 
      if(!$stmt->bind_param('ssssssissssssi', $firstname, $lastname, $skills, $competency, $profession, 
           $user_name, $phone, $address, $email, $bio, 
           $gender, $dob, $country, $userId)){ 
      echo "Binding paramaters failed:(" . $stmt->errno . ")" . $stmt->error; 
        } 
      if(!$stmt->execute()){ 
        echo "Execute failed: (" . $stmt->errno .")" . $stmt->error; 
        } 


        if($stmt) { 
         $_SESSION['main_notice'] = "Successfully Updated!"; 
            header('Location: profile.php'); 
             exit; 

        }else{ 
          $_SESSION['main_notice'] = "Some error, try again"; 
          header('Location: '.$_SERVER['PHP_SELF']); 
         } 

      $stmt->close(); 



     } 

       $stmt = $con->prepare("SELECT firstname, lastname, skills, competency, user_name, avatar, profession, email, dob, gender, country, phone, bio, address, created_at FROM user WHERE id = ?"); 
      $stmt->bind_param('s', $userId); 
      $stmt->execute(); 
      $stmt->store_result(); 
      if($stmt->num_rows == 0) { 
       echo 'No Data Found for this user'; 
      }else { 
       $stmt->bind_result($firstname, $lastname, $skills, $competency, $user_name, $avatar, $profession, $email, $dob, $gender, $country, $phone, $bio, $address, $created_at); 
       $stmt->fetch(); 

       $stmt->close(); 

      } 
       ?>
