Asset Approval List is a table with lots of row of data and a button, after clicking the button, it will link to Asset Approval Form. I would like to fetch the data from the same row in Asset Approval List to my Asset Approval Form. The data in the table of Asset Approval List is fetched from mysql phpmyadmin. Any idea how to link the same data to Asset Approval Form?
This is my Asset Approval List
This is my Asset Approval Form

Answer 1

Assuming there's a unique ID column in the table, you should include that in the call to approval():
echo '<td><input type="button" value = "View" onclick="approval(\'' . $row['SerialNumber'] . '\')"></td>';
Then change approval() to include the ID in the URL.
function approval(serial){
window.location.href = "AddAssetApproval.php?serial=" + serial;
}
And AddAssetApproval.php should use $_GET['serial'] to display the appropriate approval form for that serial number.
$stmt = $conn->prepare("SELECT * FROM waiting_approval WHERE SerialNumber = ?");
$stmt->bind_param("i", $_GET['serial']);
$stmt->execute();
$result = $stmt->get_result();
$row = $result->fetch_assoc();
