How to update specific row from a dropdown list? - php

Question

I want to update the table after after the option from drop down list is selected. However, when I click approve button, the car plate is not updated in the database. Can someone help me? Thanks.
<?php
mysql_connect("l","t","")or die(mysql_error()); // connect to server
mysql_select_db("car")or die("Cannot connect to database") ;
$query=mysql_query("Select * from list "); //SQL Query
echo "<table><tr>
<th>Name</th>
<th>Destination</th>
<th>Time</th>
<th>Date</th>
<th>Car Requested</th>
<th>Purpose</th>
<th>Car Approve</th>
<th>Approve</th>
<th>Reject</th>
</tr>";
while($row=mysql_fetch_array($query))
{
if($row['status'] =='Pending'){
echo"<tr>";
echo'<td align="center">'.$row['employee']."</td>";
echo'<td align="center">'.$row['destination']."</td>";
echo'<td align="center">'.$row['time']."</td>";
echo'<td align="center">'.$row['date']."</td>";
echo'<td align="center">'.$row['car']."</td>";
echo'<td align="center">'.$row['message']."</td>";
echo'
<form action="approve.php" method="GET">
<td align="center">
<select name="car_plate">
<option>--Select Car--</option>
<option>WBN 3041</option>
<option>WWW 4545</option>
<option>BBB 1111</option>

</select>
</td>
</form>
';
echo'<td align="center">Approve </td>';
echo'<td align="center">Reject </td>';
echo"<tr>";
}
}
echo"</table>";
?>
<script>
function fapprove(id)
{
var r=confirm("Are you sure you want to APPROVE this record?");
if(r==true)
{
window.location.assign("approve.php?id=" + id);
alert('APRROVED! =)');
}
}
</script>
approve.php
if($_SERVER['REQUEST_METHOD'] == "GET")
{
mysql_connect("l", "r","") or die(mysql_error()); //Connect to server
mysql_select_db("car") or die("Cannot connect to database"); //Connect to database
$id = $_GET['id'];
$car_plate = $_GET['car_plate'];
mysql_query("UPDATE list SET status='Approved' WHERE id='$id'");
mysql_query("UPDATE list SET car_plate='$car_plate' WHERE id='$id'");

Answer 1

You didnt pass the carplate number in your javascript function. Use below code
function fapprove(id)
{
var r=confirm("Are you sure you want to APPROVE this record?");
if(r==true)
{
var carPlate = $("#car_plate").val();
window.location.assign("approve.php?id="+id+"&car_plate="+carPlate);
alert('APRROVED! =)');
}
}
add id to the select dropdown as <select id="car_plate" name="">
Hope it will work for you. If you need any help I'm ready to guide you...
