You should ALWAYS check the result of a call to mysql_query():

 if ($view === false) { echo "Fatal error: " . mysql_error(); }


Your problem is that the SQL for update is incorrect and it should be:

  "UPDATE photoshop_tutorial SET view = $vplus WHERE id = $id"

You can also do the increment inside the SQL so:

  "UPDATE photoshop_tutorial SET view = view + 1 WHERE id = $id"
