Durr, you are quite right; I was being a goose. I suddenly lurched into 
an alternative universe where we were talking about links with 
JavaScript confirmation, rather than form submission.

My bad...I'm having a mid-life crisis, I think.

<tip type="php - string display" author="Ian Anderson">
Truncating data upon display is a common task, and there are lots of 
ways to do it. Thing is, I hate seeing words being broken when this 
happens because it's typographically poor form. This humble PHP function 
takes a string and a maximum display length; if the supplied string is 
greater than the  length, it is truncated to the last space before the 
maxlength and ellipsis is added. If the string is less than the 
threshold, it is displayed in total.

function elide($str, $len) {
   $strlen = strlen($str);
   if ($strlen > $len) {
     $str = substr($str, 0, $len);
     $lastSpacePos = strrpos($str, " ");
     $str = substr($str, 0, $lastSpacePos) . '...';
     return $str;
   } else {
     return $str;
   }
}
