Answer 1

Use the name attr of checkbox as array like 'id[]'

like.

<form method="post">
<table>
<tr>
        <td><input type="checkbox" value="<?php echo $row_id;?>" name="id[]"></td>
        <!-- other table data <td> -->
    </tr>

    <tr>
        <td><input type="checkbox" value="<?php echo $row_id;?>" name="id[]"></td>
        <!-- other table data <td> -->
    </tr>


</table>

<input type="submit" name="update_data" value="update">
</form>

After submit the form you will get all the checked id in array. using implode get the id separated by comma and use in update query.

like.

<?php

if(isset($_POST['update_data'])){
    echo $query_id = implode(',', $_POST['id']);

    //write the update query
}
?>
