Just want to know how to find the match value on the dropdown list and display the value as current selected for update.
this is my table query and displayed on page with update link beside each row. All update link is working and the value displayed on hidden textbox. My problem is just on one column $trandescription, this will be post on dropdown.
this is my display table.
while($row = mysql_fetch_array($query))
{
echo "
<tr>
<td style='border:1px solid; color:gray' width='145px' align='center'>".$row['patientid']."</td>
<td style='border:1px solid; color:gray' width='145px' align='center'>".$row['trandate']."</td>
<td style='border:1px solid; color:gray' width='600px'>".$row['trandescription']."</td>
<td style='border:1px solid; color:gray' width='90px' align='center'>".$row['tranquantity']."</td>
<td style='border:1px solid; color:gray' width='90px' align='right'>".number_format($row['tranunitprice'],2)."</td>
<td style='border:1px solid; color:gray' width='150px' align='right'>".number_format($row['tranamount'],2)."</td>
<td style='border:1px solid; color:gray'><a href='updatebillindex.php?update=$row[id]'>update</a></td>
<td style='border:1px solid; color:gray'><button class='btn btn-default btn-sm';><a href='updatebillindex.php?update=$row[0]'>edit
<span class='glyphicon glyphicon-trash'></span></a></button></td>
</tr> ";
this is my update page
<?php
if (isset($_GET['update']))
{
$id = $_GET['update'];
$query = mysql_query("SELECT * FROM transaction where id = '$id'") or die ("could not search");
$count = mysql_num_rows($query);
while ($rows = mysql_fetch_array($query)) {
$id = $rows['id'];
$tranid = $rows['tranid'];
$trandate = $rows['trandate'];
$patientid = $rows['patientid'];
$transactiontype = $rows['transactiontype'];
$trandescription = $rows['trandescription'];
$tranquantity = $rows['tranquantity'];
$tranunitprice = $rows['tranunitprice'];
$tranamount =$rows['tranamount'];
$gettrandescription = $rows['trandescription'];
}
}
?>
