database - Combine $_GET and $_POST in PHP?

Question

for some friends and family (different sites), I created a script that allows them to input data into the database. With

echo ("<a href="./pagina.php?ID=" . $row['ID'] . "">" . $row['ID'] . "<br>");

, I 'send' the ID of the requested table to the URL.

In pagina.php, I have this code:

ID: <?php echo $_GET["ID"]; ?>

That works, of course, but now I want to use that ID to also display the data from the database, so not from the URL. These values are " . $row['onderwerp'] . " and " . $row['tekst'] . " (There may be more values to come, but I'm just a beginner, trying to get something to work).

I know this is possible, but I just can't get anything to work, as I have just started learning PHP.

I hope you can help me.

If you don't care whether data came from a $_COOKIE, $_GET, or $_POST, you can use $_REQUEST.
