Hey, guys, I'm new in the whole php thing.
I believe what I am asking here is super simple to do, I just wasn't able to find it anywhere.
In the code below, you guys will notice that not all the fields show in every change of the dropdown menu TYPE, and, of course they don't, that's the whole point. I mean, I have arranged for each TYPE to have it's own fields. The thing is: how can I adapt for the html ECHO code to show ONLY the "labels", I mean, the pieces of HTML in the while($row = mysqli_fetch_array($result)), for the fields that were filled in? I mean, I don't want that in RESULT there are the "labels" of the fields whose values are there.
<?php
$con=mysqli_connect("localhost","root","","activitytest1");
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
if (isset($_POST['submit'])) {
$stmt = mysqli_prepare($con, "INSERT INTO activitytest1 (type, author, taskpre, taskdescription, outcome, semipre, semiwhile, exercisedescription, practicepre, practiceinstructions, leadin, gamepre, gameinstructions, videopre, videowhile, videopost, songpre, songwhile, songpost, mimioinstructions, otherinstructions, path, books, grouping, time)

mysqli_stmt_bind_param($stmt, 'sssssssssssssssssssssssss', $type, $author, $taskpre, $taskdescription, $outcome, $semipre, $semiwhile, $exercisedescription, $practicepre, $practiceinstructions, $leadin, $gamepre, $gameinstructions, $videopre, $videowhile, $videopost, $songpre, $songwhile, $songpost, $mimioinstructions, $otherinstructions, $path, $books, $grouping, $time);
