Validate user input to check for letters in numbers  (See more user questions)

Hi

Here's some fiddling material!

if(!is_numeric($_REQUEST['age'])){$errors[] = "Age must be a numeric
value";}

if(!is_numeric($_REQUEST['phone'])){$errors[] = "Phone number must be a
numeric value";}

if(strlen($_REQUEST['phone']) != 10){$errors[] = "Phone number must be ten
digits long";}

You can put those lines in the script, pretty much anywhere (you can use
one, some or all of them) so long as it's before the code that prints the
errors. Replace 'age' and 'phone' with the exact name of the form field.
You can change the error messages (between the quotes) to suit.

Just thinking, one option for the age input could be to use a drop-down
<select> input with a list of numbers from 1??? to 100???!! That way, if
submitted from the form, the value will always be numeric.

Any questions, just let me know.

Best wishes.

Thanks, Charles. I understand completely about the custom
validation...can't do it for everyone. Would you possibly have an
example for me to fiddle with? I'm pretty good at figuring things out.
I used to do a lot of programming years ago, so most of the logic of
PHP make sense to me, I've just never studied PHP specifically.

Also, regarding my email address, I'm not sure why you're getting an
error. I haven't had anyone else experience a problem...however I have
confirmed that I'm not getting yours through my wenzelcomputer account
when you copy me at that address...so I'm not sure what's going on.
I'll remember to use my other address if I need to email you further.

Thanks again!
