What kind of a limit do you have in mind?

[techker]

just like a limit of 10 caracters in the box

[WingedPanther]

You can use the maxlength property to limit text input of an input field.

i think the notification on the forums dosnt work all the time..

I would do something like this:

function smarttopic($topic, $max=30, $min=0) {
    if ($min == 0) {
        $min = $max-10;
    }
    if (strlen($topic) < $max) {   
        return $topic;  //if string isn't too long, return the whole string
    } else {
        $part = substr($topic, $min, $max);
        $pos = strpos($part, " ");
        if ($pos) { // if there is a space between min and max, cut at it
           return substr($topic, 0, $min+$pos)."...";
        else { // otherwise, cut at mid between min and max
           return substr($topic, 0, $min(+($max-$min)/2))."...";
        }
    }
}

usage:

echo smarttopic("this is a long but spaced topic that will have a good cut", 30, 20);

echoes

"this is a long but spaced..."

echo smarttopic("long word topics like intercontinental airlines"), 40);

echoes

"long word topics like intercontinen..."
