Hi group,
I have a function which validates a string using preg match.
A part looks like
if( !preg_match( '/^([a-z0-9]+(([a-z0-9_-]*)?[a-z0-9])?)$/', $string )
||
preg_match( '/(--|__)+/' ,$string) ) {
i wonder how i could combine those two into one ...
I tried a few different options of putting the second match into the
first one,
using things like [^__]+ etc, but nothing worked for me.
it should prevent double (or more) dashes or underscores behind each
other.
hello-there = ok
hello--there != ok
Any help would be great.
Frizzle.
