Another problem, where I put connect() I get an error saying it can’t connect.

that’s the website link if you want to test it.

is connect() part of the code? if so it should end in a semi colon ;

If not, can you put [php] tags around the code.

RaythXC is correct you omitted a semicolon.

connect() or correctly connect(); calls another php function oddly enough called connect(). If adding the semicolon does not solve your problem, providing the code for the function connect() can help us, help you.

You might want to consult your PHP error logs. There you would have seen a fatal error on that line. PHP has no error reporting other than through the logs. I keep my console open when developing. Just because your code actually runs, doest mean there’s nothing funky in your code. You might be amazed at the number of warnings that are logged…
