guys, I'm new in the whole php thing and I'm mot familiar with the terminology and all the functions and such. 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" (let's call what I'm putting in bold in e.g.: . "< b r />Preview the Task:" . $row['taskpre']) and all the similar elements that), I mean, the pieces of HTML in the while($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.
Here is the code:
<?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)
VALUES
(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)");
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);

mysqli_stmt_execute($stmt);
mysqli_stmt_close($stmt);
}
$result = mysqli_query($con,"SELECT * FROM activitytest1");

P.S.: The page is a dropdown menu that, having each one of its options selected, will change the fields that show in the page. I mean, when I select "Video" in the dropdown menu, it shows the fields - which are textareas: "videopre", "videowhile", and "videopost". If I select "Exercise", though, the only field it shows is "exerciseinstructions".
So, I want that this piece of HTML ""<br/>Preview the Task:"" only shows if the value . $row['taskpre'] is filled in, and so forth, for all the oether ones. Otherwise, I don't want that the "<br/>Preview the Task:" echoes with the rest of the code, ok?
This is the ECHO that I get when I submit a "Task" (the task values are: 'taskpre', 'taskdescription' and 'outcome'):
http://i296.photobucket.com/albums/mm177/JuniorCodi/php_zps5ca6aa90.png
In the picture above I marked with a check what I want to echo and what's in red is what I don't want to echo when I select TASK.
I am a total newbie at this and I don't know if an IF statement would work inside a WHILE statement (at least when I tried there were errors). Can anyone help me by giving me a sample of how this code would be?
