Stupid Regex Question...
Ok, i never said I was good with regex, but theoretically this SHOULD work, but it doesn't...lol.

Code:
if(!preg_match("/[a-zA-Z]{2,15}+\s{1,2}+[a-zA-Z]{2,25}+$/", $name))
{
error("The name you provided not appear to be valied. Please note it needs to be your FULL name. Please try again...");
}

The error code returned is;

Quote:
Warning: Compilation failed: nothing to repeat at offset 14 in c:\program files\nusphere\apache\nsdocs\test\wedding\add.php on line 212

Anyone got an idea on why this is? I'm trying to search for 2-15 characters for the first name, then no more than 2 spaces, and then 2-25 charahters for the last name. For some reason it doesn't like the formatting (if I remove the {...} parts it works ok).

Thanks

If you are using {2,15} and {1,2} and {2,25} then why do you also have + Wink

How about:

if(!preg_match("/^[a-z]+\s[a-z]+$/i", $name))

I assume you can use "i" like in perl?

Incase their name is something like 'John Paul Simpson' Wink Lots of people have 3 word long names.

Yeah but the point I am making is that using + the way you used it is wrong.

Never mind, I got it working with;

if(!preg_match("/^[a-zA-Z]{2,15}\s{1,2}[a-zA-Z]{2,25}\s{0,2}[a-zA-Z]{0,20}$/i", $name))

Wink
