Any of you guys know php? I'm supposed to fix something but can't find the problem. I have never used php before (I don't do web pages and usually program in C++) and the source I was given seems OK to my untrained eye... here it is:

Code:

<form action="HProbe.php" method="post">
  <table><tr>
<?php
if ($_POST['lieder'] == '1') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/John.mp3" autostart="yes" id="player" /></CENTER></td>'}
else if ($_POST['lieder'] == '2') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Gospell.mp3" autostart="yes" id="player" /></CENTER></td>'}
else if ($_POST['lieder'] == '3') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Boogie.mp3" autostart="yes" id="player" /></CENTER></td>'}
else if ($_POST['lieder'] == '4') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Time.mp3" autostart="yes" id="player" /></CENTER></td>'}
else if ($_POST['lieder'] == '5') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Stella.mp3" autostart="yes" id="player" /></CENTER></td>'}
else if ($_POST['lieder'] == '6') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Danny.mp3" autostart="yes" id="player" /></CENTER></td>'}
else if ($_POST['lieder'] == '7') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Mondschein.mp3" autostart="yes" id="player" /></CENTER></td>'}
else if ($_POST['lieder'] == '8') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Elise.mp3" autostart="yes" id="player" /></CENTER></td>'}
else if ($_POST['lieder'] == '9') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Bach.mp3" autostart="yes" id="player" /></CENTER></td>'}
else if ($_POST['lieder'] == '10') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Blue.mp3" autostart="yes" id="player" /></CENTER></td>'}
else if ($_POST['lieder'] == '11') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Help.mp3" autostart="yes" id="player" /></CENTER></td>'}
else if ($_POST['lieder'] == '12') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Dirge.mp3" autostart="yes" id="player" /></CENTER></td>'}
else {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/John.mp3" autostart="yes" id="player" /></CENTER></td>'}
?>
  </tr>

</form>

The file is called HProbe.php by the way, so it calls itself.

By the way, the problem is that every single file gets loaded and cosequently crashes the browser.

[DeadlyAvenger]

Looks like it's because you havn't put a semicolon at the end of each line.

PHP requires each statement to end with a semicolon. The code below works

Code:

<form action="HProbe.php" method="post">
  <table><tr>
<?php
if ($_POST['lieder'] == '1') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/John.mp3" autostart="yes" id="player" /></CENTER></td>';}
else if ($_POST['lieder'] == '2') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Gospell.mp3" autostart="yes" id="player" /></CENTER></td>';}
else if ($_POST['lieder'] == '3') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Boogie.mp3" autostart="yes" id="player" /></CENTER></td>';}
else if ($_POST['lieder'] == '4') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Time.mp3" autostart="yes" id="player" /></CENTER></td>';}
else if ($_POST['lieder'] == '5') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Stella.mp3" autostart="yes" id="player" /></CENTER></td>';}
else if ($_POST['lieder'] == '6') {echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Danny.mp3" autostart="yes" id="player" /></CENTER></td>';}

Thanks, but unfortunately no, it does not work. The very same problem still occurs.

[Alex]

Try this. I didn't have time to test it.

Code:

<?php
switch ($_POST['lieder']){
	case 1: echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/John.mp3" autostart="yes" id="player" /></CENTER></td>'; break;
	case 2: echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Gospell.mp3" autostart="yes" id="player" /></CENTER></td>'; break;
	case 3: echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Boogie.mp3" autostart="yes" id="player" /></CENTER></td>'; break;
	case 4: echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Time.mp3" autostart="yes" id="player" /></CENTER></td>'; break;
	case 5: echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Stella.mp3" autostart="yes" id="player" /></CENTER></td>'; break;
	case 6: echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Danny.mp3" autostart="yes" id="player" /></CENTER></td>'; break;
	case 7: echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Mondschein.mp3" autostart="yes" id="player" /></CENTER></td>'; break;
	case 8: echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Elise.mp3" autostart="yes" id="player" /></CENTER></td>'; break;
	case 9: echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Bach.mp3" autostart="yes" id="player" /></CENTER></td>'; break;
	case 10: echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Blue.mp3" autostart="yes" id="player" /></CENTER></td>'; break;
	case 11: echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Help.mp3" autostart="yes" id="player" /></CENTER></td>'; break;
	case 12: echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/Dirge.mp3" autostart="yes" id="player" /></CENTER></td>'; break;
	echo '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/John.mp3" autostart="yes" id="player" /></CENTER></td>';
}
?>

Lieder saves strings, not integers, but I get the idea. By the way: Does php not use a default: case when switching? Or, more to the point, is it enough to just put the default operation without declaring this the default case?

And thanks again, I'll try it later

[DeadlyAvenger]

That's weird, the version I used above worked fine on my test rig running on my pc.

It doesn't matter if it's a string or integer in PHP, there is no variable definition and PHP just 'guesses' the appropriate type and can change type on the fly.

But the above code should work too.

[Alex]

For strings, just add "" (case "1": ), but php usually converts to int if the string is one.
In php, the default case can be declared with

Code:

default: echo "yourstuff";

but I think it works without as well.

Also, if you look for help with php, always try "php.net/yoursearch", in this case php.net/switch.

Also, echo $_POST['lieder'] at the beginning just to make sure your server doesn't screw things up somehow.

[Mosch]

Problem solved. It was not the code at all - the hoster just needed confirmation to activate PHP. Why? I have no freaking idea. I found out about that one when I, frustrated and pissed off, installed an apache server and PHP on my own PC, just for this single php file. Lo and behold, the code you guys gave me worked like a charm and a little call to the hosting provider cleared the rest up nicely. So now a local musician has a working homepage which he would like to express his thanks for.

Lazy man's version (just need to modify the song array to add new ones...):

Code:

<?php
$lieder = array('John' => 'Blues',
                'Gospell' => 'Gospel',
                'Time' => 'As time goes by'
                /* you get the idea */);

if (isset($_POST['lieder']) && isset($lieder[$_POST['lieder']]) ) { /* check if set and really a song */
    echo  '<td colspan=2><CENTER><embed type ="audio/mpg" src="audio/'. $lieder[$_POST['lieder']] . '.mp3" autostart="yes" id="player" /></CENTER></td>';
}


// -------------- now the selector -----------------
?>
<p>
    <select id="liedCh" name="lieder">
<?php
    foreach ($lieder as $file => $title) {
         echo "<option value=\"$file\">$title</option>";
    }
?>
 </select>
</p>

just thought I should point this out to you, If you need to mess around with the page more often, make life easier for yourself.

I hate PHP - had enough of it on this site tbh

[Gonk]

wtf is PHP lol (dnt wanna know i reckon)

[Junta]

Its a programming language - popular for website creation

I hate PHP - had enough of it on this site tbh

Yeah, pretty much hate it too. It's okay for small websites but for serious development, the fact that it is not properly typed soon comes around and bites you in the ass. (Trust me, I speak from personal experience...)
You would want to do serious stuff in Java Enterprise, but that too is a pain in the arse, what with all the additional packages you need (templating, MVC framework, ugh...)

In short: Web development sucks balls.

Now that's a fact. I much prefer devving desktop applications myself, too.
