I need help passing a value from a database. I've done this successfully with drop down boxes, and getting the selection then posting with a submit button where it would fill the tables in Display.php successfully. However, I'm now using an html table that fills with values as a list and uses the serial number as a hyperlink.

When the user selects the link and it opens Display.php, I want to grab the serial number associated with that link/row and use it in the SQL query on the display.php page so it can match that serial number with a stageID in my staging table and select all values for that row.

In the following code, if I debug the $_GET array, it shows the correctly chosen serial number. If I debug/print $_GET and $result1, I get:

Array ( [id] => 70066665 ) mysqli_result Object ( [current_field] => 0 
[field_count] => 230 [lengths] => [num_rows] => 0 [type] => 0 )

The fact that these are showing the correct serial number and row lengths, I know that the dashboard page and hyperlink code are working, as well as my SQL connection. I feel like there may be an issue in the way I've created the query on Display.php where it just isn't grabbing or matching correctly.

Here is the code:


$query1 = "SELECT * FROM staging;";
$result1 = mysqli_query($connect,$query1);
while($row = mysqli_fetch_array($result1)){
    <td><? echo $row['workOrderPacket'];?>&nbsp;</td>
    <td><? echo $row['workOrderNum'];?>&nbsp;</td>
    <td><? echo $row['date'];?>&nbsp;</td>
    <td><? echo $row['utility'];?>&nbsp;</td>
    <td><? echo $row['serviceName'];?>&nbsp;</td>
    <td><? echo $row['address'];?>&nbsp;</td>
    <td><? echo $row['serialNumber'];?>&nbsp;</td>
    <td><?php echo '<a href="Display.php?   id='.$row['serialNumber'].'">'.$row['serialNumber'].'</a>'; ?>  </td>   



$query1 = "SELECT * FROM staging WHERE stageID = ".$_REQUEST['id'].";";
$result1 = mysqli_query($connect,$query1);

while($row = mysqli_fetch_array($result1)){
/////20 HTML tables filled with values from database

    In your hyperlink, you set the id using serialNumber but in your display.php, you are querying the result using stageID.
