麻烦图像发布和mysql BLOB变量

Question

I have a form for creating employee and I need to store images in my database (using BLOB MySQL datatype). I use this code and I get an error. Is it about this line?

$file=file_get_contents($_FILES["image"]["tmp_name"]);

what is wrong with this code???

if (isset($_POST['submit']))
{


    $name=mysqli_prep($_POST["name"]);
    $family=mysqli_prep($_POST["family"]);
    $id=$_POST["id"];
    $staff_id=$_POST["staff_id"];
    $account_number=$_POST["account_number"];
    $sex=$_POST["sex"];
    $number_of_children=$_POST["number_of_children"];
    $tel=$_POST["tel"];
    $address=$_POST["address"];
    $no=$_POST["no"];
    $working_record=$_POST["working_record"];
    $marital_state=$_POST["marital_state"];
    $employer_id=$_POST["employer_id"];
        $file=file_get_contents($_FILES["image"]["tmp_name"]); 


    $query  ="INSERT INTO Employee (";
    $query .="Name,Family,ID,Staff_ID,Account_Number,Sex,Number_of_Children,";
    $query .="Tel,Address,No,Working_Record,Marital_State,";
    $query .="Employer_ID,Image)";
    $query .=" VALUES (";
    $query .="'{$name}','{$family}',{$id},{$staff_id},{$account_number},";       
    $query .="'{$sex}',{$number_of_children},{$tel},'{$address}',{$no},";
    $query .="'{$working_record}','{$marital_state}',";
    $query .="{$employer_id},'$file')";        
    $result =mysqli_query($connection, $query);

       if(!$result){   
           $_SESSION["message"] ="There were some errors,fill each 
       section carefully";   
           redirect_to("creat_employee.php");
       }
       else{
           $_SESSION["message"]="filling has been done !";

           redirect_to("creat_employee.php");
    }
}
