echo "</form>";
}
echo '<table>';
}
I made a simple table which as got 3 columns, the first column is a name, second one has a textbox which contains a number (with a hidden id that I need) and last one is a button to update that specific row.
The big problem I have that it only updates the last row, therefore I read that you needed to add [] to ur names and loop through it to update that specific row.
It's still not working and I can't figure out how to just let one specific row update with that [] array.
Thank you for reading and helping.

$_request['id'] is nothing but array ,also header should not be in loop
so Write This
mysql_data_seek($result,0);
$counter=0;
while( $row=mysql_fetch_array($result))
{
echo "<tr>
<td>".$row['name']."</td>
<td> "?><input type="hidden" id="id" name="id[]" value=" <?php echo $row['id']?>"> <input id="txt_port" name="txt_port[]" type="text" class="required" title="Port. This is a required field" value=" <?php echo $row['Destination_port'] ?> "></td>
<?php
echo "<td><a onclick='return show_confirm();'><input name='update' class='button' type='submit' value='Update'></a></td></tr>";
if(ISSET($_POST["update"]) and $_SERVER['REQUEST_METHOD'] == "POST"){
$id=$_REQUEST['id'];
$port=$_REQUEST['txt_port'];
$menu=$_GET['Menu'];
$result=mysql_query("UPDATE protocols SET Destination_port=".$port." WHERE id=".$id[$counter].";");
$counter++;
// header("Location: Overview.php?Menu=".$menu."&Overview=1");
}
Instead of this
mysql_data_seek($result,0);
while( $row=mysql_fetch_array($result))
{
echo "<tr>
<td>".$row['name']."</td>
<td> "?><input type="hidden" id="id" name="id[]" value=" <?php echo $row['id']?>"> <input id="txt_port" name="txt_port[]" type="text" class="required" title="Port. This is a required field" value=" <?php echo $row['Destination_port'] ?> "></td>
<?php
echo "<td><a onclick='return show_confirm();'><input name='update' class='button' type='submit' value='Update'></a></td></tr>";
if(ISSET($_POST["update"]) and $_SERVER['REQUEST_METHOD'] == "POST")
{
$id=$_REQUEST['id'];
$port=$_REQUEST['txt_port'];
$menu=$_GET['Menu'];
$result=mysql_query("UPDATE protocols SET Destination_port=".$port." WHERE id=".$id.";");
header("Location: Overview.php?Menu=".$menu."&Overview=1");
}
