Question

I am trying to take input from an HTML form where there are checkboxes. The checkboxes are created with the student_ids from the database. Like so:

 <td><input type="checkbox" name="{$row['STUDENT_ID']}" />

What I want to do is step through the Students table and check all of the entries against which of the checkboxes are checked. I want to then delete the entries from the database that have been checked with the checkboxes.

  8    $query = "SELECT STUDENT_ID From Students";
  9 $result = mysql_query($query) or die(mysql_error());
 10 while($row=mysql_fetch_array($result)){
 11   $checkname=$row['STUDENT_ID'];
 12   foreach($_POST[$checkname] as $student_id =>val)
 13   {
 14   if($val == 'YES'
 15     {
 16       echo $_POST['STUDENT_ID'];
 17       $query = "DELETE FROM Students WHERE STUDENT_ID" . mysql_real_escape_string($STUDENT_ID);
 18     }
 19   echo $query;
 20   $result = mysql_query($query) or die(mysql_error());
 21   //echo $POST['STUDENT_ID'];
 22 }
 23 }

Answer 1

Create an array of checkbox :

    <input type="checkbox" name="studentID[]" value="{$row['STUDENT_ID']}" />

From PHP :

    $studentID = $_POST['studentID'];

    foreach($studentID as $ID){
        echo $ID.'<br />'."\n";
    }

EDIT :
Not sure but I think this is the right way :

    $studentID = $_POST['studentID'];

    $i=0;
    foreach($studentID as $ID){
        $i++;
        echo $_POST['studentID'][$i].'<br />'."\n";
    }
