Session in While Loop PHP

<form action="includes/xxx.php"  method="get">
                <td><?php echo $row['id']; 
                        $_SESSION['id'] = $row['id'];
                ?> 
                    </td>

                <td><?php echo $row['length']; ?></td>
                <td><?php echo $row['name']; ?></td>
                <td><?php echo $row['value'];
                    $_SESSION['value'] = $row['value'];
                ?>
                    </td> 

                <td><input type="text" name="value" placeholder="XXX"></td> 

                <td><button type="submit" name="submit" value="submit">  OK </button> </td>
            </form>

In the upper code, I’m displaying my db table with a while loop

Each row has ID/LENGTH/NAME/VALUE/INPUT/BUTTON.

I get a value from the user, and I want to add it with the value in the same row and then update my db table.

GET method / displaying / SESSIONS and Update are done, but when I’m filling the input field the result saved in the last id.

I know that my code overwrites something and it can’t understand what input I filled up.

How can I solved it?

Answer

Don’t use sessions this way. Add a separate hidden input box to send the ID to the server for processing.

<td>
    <input type="hidden" name="row_id" value="<?php echo $row['id']; ?>">
    <input type="text" name="value" placeholder="XXX">
</td>

Now when you submit the form you will have 2 values, $_GET['row_id'] and $_GET['value']. Use the row_id to update the row you are trying to change.

If needed, you can still set the session values when you are processing the submitted form.
