Php form validation minimum character need avoid white space?

Question

In our HR system i put a validation user have to put a note minimum 8 letters. but what if they don't put they can't punch in. but what they are doing is they are put 8 white space they can punch in :( so i want restrict them to put note avoid white space

if(empty($openPunch)){

            $currentTime = $req->time;
            if (strtotime($currentTime) >= strtotime('09:30')){
                if(strlen($req->note) < 8){
                $time = (strtotime($currentTime) - strtotime('09:30'));
                $minutes = floor($time / 60);
                $minute = $minutes%60;
                $hours = floor($time / 3600);
                return new IceResponse(IceResponse::ERROR,"Today you are late ".$hours.":".$minute." Hours    You Can't Punch in without Fill the Correct Reason");

    }
    }

    $openPunch = new Attendance();
}

This is like repairing a carburetor with a bandaid. Users will notice they can put 8 dots or anything else instead. — Julie Pelletier

Why is it flagged as javascript? Do you want to perform a client-side check as well? — Arnauld

and you would also provide validation to prevent special characters in order to make it more optimal. check this link to know how to do it.

Use trim() function

The trim() function removes whitespace and other predefined characters from both sides of a string.

http://www.w3schools.com/php/func_string_trim.asp

      if(empty($openPunch)){

        $currentTime = $req->time;
        if (strtotime($currentTime) >= strtotime('09:30')){
            if(strlen(trim($req->note)) < 8){
            $time = (strtotime($currentTime) - strtotime('09:30'));
            $minutes = floor($time / 60);
            $minute = $minutes%60;
            $hours = floor($time / 3600);
            return new IceResponse(IceResponse::ERROR,"Today you are late ".$hours.":".$minute." Hours    You Can't Punch in without Fill the Correct Reason");

     }
    }

     $openPunch = new Attendance();
 }
