I'm having an issue with register.php.

When I try to run the file on my web server and press submit (no matter the inputs) I get this fatal error message:

( ! ) Fatal error: Call to undefined function query() in  /home/ubuntu/workspace/pset7/public/register.php on line 18

I don't know exactly where query() is defined or what to do. Could this be a permissions issue? Code

Are you sure that your directory tree is correct? Do you have in a pset7 directory, two directories, includes and public (and anything else that should be there)? Do you have a file named config.php and a file named functions.php in includes and a file named register.php in public?

If you have those correct, then chmod 711 both directories and chmod 600 all PHP files.

Let me know of the result. Happy Coding!

It looks like this is happenning because somewhere in the pset spec it says that you need to use CS50:: before any query statements(I think it's something to do with the database being run with mysql50, though I am not sure). So for example, instead of saying:

$variable = query(blah blah);

you need to say:

$variable = CS50::query(blah, blah);

Hope this helps.

  • All of my code had this CS50:: prefix. – Simonnnn Aug 27 '16 at 23:54
