Hi there,

I know this seems a simple question, but I can't pinpoint the reference.

Does anyone know how to check that a user has entered only numbers into a submitted form using php.

The problem is that the form converts the number into a string so that the command 'is_int' does not apply.

What I'm looking for, is probably the php equivalent of the Javascript function:

if (!parseInt(users.cell_number.value, 10)) {

e.t.c......

Thank you very much if you can help.

Regards,

Jason
