The code you provide is not complete/not enough to help you.
Let's see the query gan gan

Try this and let us know if it works:

Put the following code at the beginning of your script before you connect to database (if your database connection script is in another file, put this code at the beginning of that file only)

display_errors(true);
ini_set('display_errors', 'On');

Try this instead

if ($query_num_rows < 1)
{
echo 'invalid username/password' ;
}
else
{
echo 'ok.' ;
}

Did you get any error and what isthe error code

Run ur code thru localhost turn on ur server ur if statement is correct.

Bro, you don't run php like client sided technologies like html and parts of javascript. You need local server installed, and run the program through localhost.
