making a minimum number of characters in a field	Can't Post

how do you make a script do one thing if there are x many characters or less in a form field and do something else if there are more than that many?

This is most likly obvious and I think i know how to do it, but when i tried it didn't work, probably some typo, or i just plumb dont know...

I'm not familiar with CGI at all, but after the submit button is pressed, you can use the following construct:

Code

if ( length($field) > $minlength ) { 
    print "Ok. \n"; 
} 
else { 
    print "Minimal requirement not met. \n"; 
}
