How to upload images into MySQL database using PHP code

Question

I'm attempting to save photos from an HTML form to my database. To do this assignment, I wrote PHP code. The program is not only failing to insert image data into the MySQL database, but it is also not producing any error messages. Please check it. I'll provide a section of my code right here.

        /*-------------------
    IMAGE QUERY 
    ---------------*/


    $file   =$_FILES['image']['tmp_name'];
    if(!isset($file))
    {
      echo 'Please select an Image';
    }
    else 
    {
       $image_check = getimagesize($_FILES['image']['tmp_name']);
       if($image_check==false)
       {
        echo 'Not a Valid Image';
       }
       else
       {
        $image = file_get_contents ($_FILES['image']['tmp_name']);
        $image_name = $_FILES['image']['name'];
        if ($image_query = mysql_query ("insert into product_images values (1,'$image_name',$image )"))
        {
          echo $current_id;
         //echo 'Successfull';
        }
        else
        {
          echo mysql_error();
        }
       }
   }
        /*-----------------
    IMAGE QUERY END
    ---------------------*/

    <form action='insert_product.php' method='POST' enctype='multipart/form-data' ></br>
            File        : <input type='file' name= 'image' >
    </form>

Error Message You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

Can someone please help me with this?
