body: <p><strong>My site'Internet'</strong> workd well during 20 day.
  but today it have a problem with only : "Unknown column 'Array' in 'where clause'".</p>
  
  <p>the same code in localhost is working well. but after i upload to site'internet'.
  it have the same error.</p>
  
  <p>I see only: "Unknown column 'Array' in 'where clause'"</p>
  
  <p>and can not find the solution.</p>
  
  <h2>thanks.</h2>
  
  <p>Sorry, after debug careffuly,
  I found the reason.</p>
  
  <p>Click upload_file. but variable: $_FILES is not set the value ---> can not upload file to the database ----> load from database error ----> Unknown column 'Array' in 'where clause'.</p>
  
  <p>Thanks alls, but i can not find why the $_FILES is not set the value "Server in internet" but $_FILES is set the value in "Server in local host"</p>
