Hello,
I am very new to PHP, so I would greatly appreciate your help.
I am making a contact form with Name, Email and Phone text boxes. Validating email and name seems to be working fine, but phone number entry is not going so well. If I enter an invalid character (like a letter) or if I don't enter anything there, after I leave the text box, the error message is supposed to be shown above the phone number text box. And it is not happening....
