PHP use MYSQL table result as parameter for another query - php

Question

I have a table on my site that is pulled from MYSQL based on a search. I would like to be able to click a button added to the table which opens a modal with more data based on the row selected. In the below image I have a column labeled ID for the first table, which could be used for the = ? in my query, but I do not know how to set the value as a parameter first. Any thoughts on the best way to go about this?
I have $term = '%' . $_GET['itemID'] . '%'; added for the second query but need a way to bind ID 999999, 1000000, or 1000001 based on the corresponding view button. Thanks!
if(isset($_GET['term']))
{
$term = '%' . $_GET['term'] . '%';
$sql1 = "SELECT ID, Source, Contract_Number, Price_Effective, Price_Expiration, Min_Price, Average_Price
FROM Both_Search WHERE SearchName LIKE ? LIMIT 10";
$stmt = $conn->prepare($sql1);
$stmt->bind_param("s", $term);
$stmt->execute();
$result1 = $stmt->get_result();
while($row1 = $result1->fetch_assoc()) {
echo "<td>" . $row1["ID"] . "</td>"; <----would want this to be the parameter for next query
echo "<td>" . $row1["Source"] . "</td>";
echo "<td><a target='_blank' rel='noopener noreferrer' href='contracts.php?number=" . $row1["Contract_Number"] . "'>" . $row1["Contract_Number"] . "</td>";
echo "<td>" . $row1["Price_Effective"] . "</td>";
echo "<td>" . $row1["Price_Expiration"] . "</td>";
echo "<td>" . "$ " . $row1["Average_Price"] . "</td>";
echo "<td>" . "$ " . $row1["Min_Price"] . "</td>"; ?>
<td><button id="myBtn" type="button" class="btn btn-primary">View</button></td>
</tr><?php
}
}
?>

Answer 1

You got the ID as $row1["ID"] and you can use that ID for Another Query.
// Replace this
<td><button id="myBtn" type="button" class="btn btn-primary">View</button></td>
// To this
<td>View</td>
And the button 'View' will redirect to YOUR_PAGE_VIEW.php with the Param Query ID = $row1["ID"].
Now you have the ID as variable $id for Another Query what you want in the YOU_PAGE_VIEW.php.
// In YOUR_PAGE_VIEW.php
$id = $_GET['id'];
Hope this help you,
