mysql - how to update table by clicking a link in php -


i have project create point system students. student may @ solutions question, if do, should lose 2 pts , profile should updated new point score. possible update table clicking on link? attempted following: 

if($points >0) {     if(($status== '') || ($newuniq_id!= $uniq_id) || ($newquestion_id!= $quid))     {            $query = "insert status(uniq_id, user_id, user_name, question_id, status) values('$uniq_id', '$id','$name','$quid','read')";         mysql_query($query);          $newpoints = $points - $cut_points;         $newquery1 = "update $tabl_u set points = '$newpoints' uniq = '$uniq1'";         $newquer2 = mysql_query($newquery1);     } }

assuming php script myscript.php

you can create each link reference script uniqid of item want update.

<a href="myscript.php?update=true&uniqid=<?=$uniqid?>" />

then in script, can check update request:

if (isset($_get['update'])){   $uniqid= $_get['uniqid'];   $newquery= // update statement }
