UBB.Developers Forums Community Development Programming PHP and Server-side Scripting Striping information on sign up question.

I am using the following code in my sign up sub to disallow a member from using a number in their name, along with other stuff.


if (($UserName =~ m/^s/) || ($UserName =~ m/ /) || ($UserName =~ m/s$/) || ($UserName =~ m/s{2,}/) || ($UserName =~ m/|!/) || ($UserName =~ m/||/) || ($UserName =~ m/|$/) || ($UserName =~ m/^|/) || ($UserName =~ m/"/) || ($Email =~ m/s/) || ($UserName =~ m/>|

and this works fine when a member signs up with say Rob123. But if he signs up as Rob123Rob then it goes through.

Any ideas on what to add to the above to not allow any number to be used in a member sign up?

Thanks,
Parker

Either add ($UserName =~ /d/) or add ($UserName =~ /[0-9]/). They're equivalent.

That is very bad and very unmaintainable. What DO you allow to go through? Once we have that, it may be easier to help you with a solution.

Do you only want to allow letters?

Mark:

All I want to go through is alphanumerics and I want the first letter of the username to be capitalized.

Like I said what I have now works great at not allowing a number in a new registration unless the numbers are followed by an alphanumeric.

IE: Rob123 isn't allowed but Rob123Rob is allowed.

That did the trick.

Thanks a lot,

One other thing that I need is if a member tries to sign up using all caps in their username that it would automatically convert it to lowercase.

Ie:

BOB WILLIAMS would be converted to
Bob Williams.

unless($username =~ /^[A-Z][A-Za-z0-9][A-Za-z]$/)

How would I put that line in the above if statement or whould I use this on a separate line?


Thanks,

I figured out how to put this in the if statement above but when I put it in it won't allow me to sign up if I am using a lowercased name either.

So bob, BOB or Bob doesn't get passed through.

I want Bob to go through and bob to go through but not BOB.

Thanks again,
Parker
