hye all, im here just want to ask for a very basic problem about checkbox. i do search but there is nothing related to my problem.

my problem is :

  1. i have a dynamic table with checkbox on each row of my table.

  2. each row has different value since it carry out from my database.

  3. i want to multiple add from the selected checkbox into the other table.

  4. thing is fine but then, there is no value carry to the database. ( i noticed that i don carry any value into it, i dont know how to do that ).

here is the sample of my code :

    <tr bgcolor="#B9DAFC">
    <td align="center" class="text">
        <? echo $rows['subject_id']; ?></td>
    <td class="text">
        <? echo $rows['subject_name']; ?> </td>
    <td align="center" class="text">
    <input name="checkbox[]" type="checkbox"    id="checkbox[]" value="<? echo $rows['id']; ?>">

<tr align="right">
    <td colspan="3" bgcolor="#FFFFFF">
<input name="add" type="submit" id="add" value="Add!">
    foreach($_POST['checkbox'] as $add_id)
    $add_id = $checkbox[$i];    
    $sql = "INSERT INTO $tbl_name2 (subject_id, subject_name) VALUES ('$add_id', '$add_id')";
    $result = mysql_query($sql);

    // if successful redirect to user.php
    echo "<meta http-equiv=\"refresh\" content=\"0;URL=user.php\">";

thank you in advance.

Hello, first place the the insert statemen at the top of your script. use an echo in front of the insert statement to debug if the values are filled.
