data base

  schoolid   studentregid    studentfirstname studcourse   studentsection      ft001     12kqc31085        abc             bcom                 ft001     12kqc31086        def             bcom                         ft001     12kqc31087        ghi             bcom                   ft001     12kqc31088        jkl             bcom                 $mysqli=mysqli_connect('localhost','uname','pass','database');         //data ajax $standard1 = trim($_post["tclass"]); $section1 = trim($_post["tsection"]); $schoolid1 = trim($_post["tschoolid"]);  $query3="select * euser_student   studcourse='$standard1' , schoolid='$schoolid1'and studentsection='$section1' order studentfirstname   asc"; $data3=mysqli_query($mysqli,$query3)or die(mysqli_error());  while($row=mysqli_fetch_array($data3)){     $dat3 = $row['studentfirstname'];       // data ajax display data in div     echo "<table><tr><td>".$dat3."</td><td><input name='".$dat3."' type='radio' value='present'>present</td><td><input name='".$dat3."' type='radio' value='absent'>absent</td><td><input name='".$dat3."' type='radio' value='leave'>leave</td></tr></table>"; } 

final out put

                abc         o present   o absent    o leave                 def         o present   o absent    o leave                 ghi         o present   o absent    o leave                 jkl         o present   o absent    o leave   <input type="submit" id="submit_data" > </input> 

first, 2 things.

  • escape !!! don't ever use user data in query without escaping. (i use sprintf make queries, don't have to)
  • post & get: post means user adds data website, comment. think pure thing

i think looks want.
