while uploading a image using php and mysql: Warning: file_get_contents(): Filename cannot be empty -

when trying upload image photos folder having type of warning msg dont know to.. this php file

if (!isset($_files['image']['tmp_name'])) {     echo "";     }else{     $file=$_files['image']['tmp_name'];     $image= mysql_real_escape_string(addslashes(file_get_contents($_files['image']['tmp_name'])));     $image_name= addslashes($_files['image']['name']);              move_uploaded_file($_files["image"]["tmp_name"],"photos/" . $_files["image"]["name"]);              $location="photos/" . $_files["image"]["name"];              $save=mysql_query("insert add values('$location')") or die("can not insert");             exit();                      } 

this html code

<form method="post" action='ap.php' enctype="multipart/form-data"> <input name="image" id="image" type="file" /> <input type='submit' name='add' value='add'  /> </form> 

no need following lines:

$image= mysql_real_escape_string(addslashes(file_get_contents($_files['image']['tmp_name']))); $image_name= addslashes($_files['image']['name']); 

just removed , test work. checking first if condition enough.
