LOAD_FILE and PHP

Greetings all, I can't get LOAD_FILE to work in an INSERT statement from PHP. The generated sql works when you're in mysql but won't work from PHP. BSDB is my database object. sql_query basically just does a mysql_query and some error outputting stuff. There error is: Column 'photo' cannot be null My SQL statement is: INSERT INTO photo VALUES('', LOAD_FILE("/Library/WebServer/Documents/var/tmp/default_smiley.png")) The first column is an auto-increment id, the second column is the photo. Here's a code snippet: $uploaddir = '/Library/WebServer/Documents/var/tmp/'; $uploadfile = $uploaddir . $_FILES['userfile']['name']; if ($_FILES['userfile']['type'] == "image/jpeg" ||

       $_FILES['userfile']['type'] == "image/png" ||
       $_FILES['userfile']['type'] == "image/gif" )

{

      if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile))
      {
         print "File is valid, and was successfully uploaded. ";
         print "Here's some more debugging info:\n";
         print "<pre>";
         print_r($_FILES);
         print "</pre>";
         echo "<IMG SRC=/var/tmp/" . $_FILES['userfile']['name'] . "><BR>";
         $bsdb = new BSDB();
         $sql = "INSERT INTO photo VALUES('', LOAD_FILE(\"$uploadfile\"))";
         echo "$sql<BR>\n";
         chmod($uploadfile,0755);
         $result = $bsdb->sql_query($sql);
      }
      else
      {
         print "Possible file upload attack! Here's some debugging info:\n";
         print "<pre>";
         print_r($_FILES);
         print "</pre>";
      }

} Thanks for your help!!
