[RESOLVED] Simple IF ELSE query

[Virtualburn]

Hi All.. hoping you can make sense of why this won't work.

I am placing an (flash) audio player on a site which will appear with in a post, IF an audio file is present with the same name as the topic the audio player will appear, ELSE it will display some text or I would prefer nothing at all.

This is the code I am using, placing the audio player code on it's own displays and plays fine but with this code it just displays '>> No Audio' regardless of the file being present.

<!-- START OF AUDIO -->

<?php

$filename = '<?php bb_uri(); ?>bb-audio/<?php topic_title(); ?>.mp3';
$audio = '<script language="JavaScript" src="<?php bb_uri(); ?>bb-audio/audio-player.js"></script>
<object type="application/x-shockwave-flash" data="<?php bb_uri(); ?>bb-audio/player.swf" id="audioplayer1" height="24" width="290">
<param name="movie" value="<?php bb_uri(); ?>bb-audio/player.swf">
<param name="FlashVars" value="playerID=audioplayer1&soundFile=<?php bb_uri(); ?>bb-audio/<?php topic_title(); ?>.mp3">
<param name="quality" value="high">
<param name="menu" value="false">
<param name="wmode" value="transparent">
</object';

if (file_exists($filename)) {

echo $audio;
}

else {

echo ">> No Audio";
}

?>

<!-- END OF AUDIO -->

What am I doing wrong?

[Virtualburn]

When viewing the source it seems to be replacing < with %3C and so on.. so I presume the the single quotes will force the code to show as plain text although when viewed in a browser it tries to parse it as php.

<!-- START OF AUDIO -->
<script language="JavaScript" src="%3C?php%20bb_uri%28%29;%20?%3Ebb-audio/audio-player.js"></script>
<object type="application/x-shockwave-flash" data="&lt;?php bb_uri(); ?&gt;bb-audio/player.swf" id="audioplayer1" height="24" width="290">
<param name="movie" value="&lt;?php bb_uri(); ?&gt;bb-audio/player.swf">
<param name="FlashVars" value="playerID=audioplayer1&amp;soundFile=&lt;?php bb_uri(); ?&gt;bb-audio/noaudio.mp3">
<param name="quality" value="high">
<param name="menu" value="false">
<param name="wmode" value="transparent">
</object>
<!-- END OF AUDIO -->

So the question is can I force the < and > symbols to stay intact so the code is parsed correctly?

$filename = '<?php bb_uri(); ?>bb-audio/<?php topic_title(); ?>.mp3';

you need to use the hard path on the server, not a url

[Virtualburn]

Thanks for your suggestion scrupul0us but if I can't use the <?php topic_title(); ?>.MP3 element is tere another way I can see for it to check if the file is present that matches the topic title.

Would you be kind enough to offer an alternative method of performing this function?

Basically on page load it will check to see if the file exists, if it does it will load the player which in turn loads the relevant file.

If the file isn't present then I will either have some text or an image.

[Virtualburn]

I have a music player I'm trying to work in to bbpress, I will have a music file relative to a Topic. I want the php code to check t see if an dmp3 file with the same name as the Topic '<?php topic_title(); ?>.mp3' exists and if it does to show the Flash player (code below) if doesn't exist to show an image or even nothing would be fine.

I've had a go at this but I seem to come across one problem after another.

If I put this code in on it's own it works exactly as it's pasted here, when I put in inside php as an IF result it seems to loose the < and > symbols which are replaced with %3B and %3C which in turn causes the result to fail.

<script language="JavaScript" src="<?php bb_uri(); ?>bb-audio/audio-player.js"></script>
<object type="application/x-shockwave-flash" data="<?php bb_uri(); ?>bb-audio/player.swf" id="audioplayer1" height="24" width="290">
<param name="movie" value="<?php bb_uri(); ?>bb-audio/player.swf">
<param name="FlashVars" value="playerID=audioplayer1&soundFile=<?php bb_uri(); ?>bb-audio/<?php topic_title(); ?>.mp3">
<param name="quality" value="high">
<param name="menu" value="false">
<param name="wmode" value="transparent">
</object>

If somebody could point me in the right direction I don't mind figuring it out myself, I just seem to be going round in circles at the moment.

<?php

[Virtualburn]

Thanks for the code. I tried it but all it displays whether the file exists or not is http://www.site.com/

This is what I was trying before and all it showed was >> No Audio as per the text and if I viewed the source it would replace the < with %3B for anything insiode the <Script> tags

<?php

$filename = '<?php bb_uri(); ?>bb-audio/<?php topic_title(); ?>.mp3';

if (file_exists($filename))

{
echo '<script language="JavaScript" src="<?php bb_uri(); ?>bb-audio/audio-player.js"></script>
<object type="application/x-shockwave-flash" data="<?php bb_uri(); ?>bb-audio/player.swf" id="audioplayer1" height="24" width="290">
<param name="movie" value="<?php bb_uri(); ?>bb-audio/player.swf">
<param name="FlashVars" value="playerID=audioplayer1&soundFile=<?php bb_uri(); ?>bb-audio/<?php topic_title(); ?>.mp3">
<param name="quality" value="high">
<param name="menu" value="false">
<param name="wmode" value="transparent">
</object>';
}

else

{
echo '>> No Audio';
}

?>

[djjjozsi]

try this $filename:

$filename = bb_uri() . 'bb-audio/'. topic_title();.'.mp3';

[Virtualburn]

Parse error: syntax error, unexpected '.' in /home/.. blah blah

[bpat1434]

Remove the semi-colon in the middle of the line so it reads like so:

$filename = bb_uri() . 'bb-audio/'. topic_title().'.mp3'; 

[Virtualburn]

ok this is the code as it stands now.

<!-- START AUDIO -->
<?php

$filename = bb_uri() . 'bb-audio/'. topic_title().'.mp3';

$audio = '<script language="JavaScript" src="<?php bb_uri(); ?>bb-audio/audio-player.js"></script>
<object type="application/x-shockwave-flash" data="<?php bb_uri(); ?>bb-audio/player.swf" id="audioplayer1" height="24" width="290">
<param name="movie" value="<?php bb_uri(); ?>bb-audio/player.swf">
<param name="FlashVars" value="playerID=audioplayer1&soundFile=<?php bb_uri(); ?>bb-audio/<?php topic_title(); ?>.mp3">
<param name="quality" value="high">
<param name="menu" value="false">
<param name="wmode" value="transparent">
</object>';

if (file_exists($filename))

{
echo $audio;
}

else

{
echo '>> No Audio';
}

?>
<!-- END AUDIO -->

The result that displays on the page is

http://www.site.com/M>> No Audio

The 'M' is the name of the audio file and the Topic of the post.

[johanafm]

What he meant if I understood him correctly is not to change the filename part, but rather the url vs file path.

$file = '/data/www/bb-audio/'.topic_title().'mp3';

Where /data/www/ obviously have to match your file system

But I'm too tired to actually look at what your code does. However, I'm fairly certain you don't want to

<?php

$filename = '<?php

You tell php to start parsing your code, and then you put things like '<?php' in the filename. If you have php tags inside other php tags, you (most likely) have something wrong with your script, or a design flaw (which will require eval...).

[scrupul0us]

<?php bb_uri(); ?>

is the issue..

you want something like $_SERVER["DOCUMENT_ROOT"] which will give you the base path of your website

so if your audio url is for instance:

http://www.domain.com/bb-audio/some-title.mp3

then you'd want:

$doc_root = $_SERVER["DOCUMENT_ROOT"];
$filename = $doc_root.'/bb-audio/'.topic_title().'.mp3';

[Virtualburn]

ok I did that.. but I have this result.

<?php

$filename = '/home/site/site.com/bb-audio/'.topic_title().'mp3'; 

$audio = '<script language="JavaScript" src="<?php bb_uri(); ?>bb-audio/audio-player.js"></script>
<object type="application/x-shockwave-flash" data="<?php bb_uri(); ?>bb-audio/player.swf" id="audioplayer1" height="24" width="290">
<param name="movie" value="<?php bb_uri(); ?>bb-audio/player.swf">
<param name="FlashVars" value="playerID=audioplayer1&soundFile=<?php bb_uri(); ?>bb-audio/<?php topic_title(); ?>.mp3">
<param name="quality" value="high">
<param name="menu" value="false">
<param name="wmode" value="transparent">
</object>';

if (file_exists($filename))

{
echo $audio;
}

else

{
echo '>> No Audio';
}

?>

Results in

M>>No Audio

M being the topic name and the name of the file.

[Virtualburn]

code is now

<?php

$doc_root = $_SERVER["DOCUMENT_ROOT"];
$filename = $doc_root.'/bb-audio/'.topic_title().'.mp3'; 

$audio = '<script language="JavaScript" src="<?php bb_uri(); ?>bb-audio/audio-player.js"></script>
<object type="application/x-shockwave-flash" data="<?php bb_uri(); ?>bb-audio/player.swf" id="audioplayer1" height="24" width="290">
<param name="movie" value="<?php bb_uri(); ?>bb-audio/player.swf">
<param name="FlashVars" value="playerID=audioplayer1&soundFile=<?php bb_uri(); ?>bb-audio/<?php topic_title(); ?>.mp3">
<param name="quality" value="high">
<param name="menu" value="false">
<param name="wmode" value="transparent">
</object>';

if (file_exists($filename))

{
echo $audio;
}

else

{
echo '>> No Audio';
}

?>

but results in the same as above

M>>No Audio

[scrupul0us]

whats the topic title vs the mp3... remember that the browser may be rendering html entities that may not match the filename

[Virtualburn]

I've even tried just this.

<?php

$doc_root = $_SERVER["DOCUMENT_ROOT"];

if (file_exists($doc_root.'/bb-audio/'.topic_title().'.mp3'))

{
echo '<script language="JavaScript" src="<?php bb_uri(); ?>bb-audio/audio-player.js"></script>
<object type="application/x-shockwave-flash" data="<?php bb_uri(); ?>bb-audio/player.swf" id="audioplayer1" height="24" width="290">
<param name="movie" value="<?php bb_uri(); ?>bb-audio/player.swf">
<param name="FlashVars" value="playerID=audioplayer1&soundFile=<?php bb_uri(); ?>bb-audio/<?php topic_title(); ?>.mp3">
<param name="quality" value="high">
<param name="menu" value="false">
<param name="wmode" value="transparent">
</object>';
}

?>

All it displays is the title of the topic.

I also tried this

<?php
if (file_exists($doc_root.'/bb-audio/'.topic_title().'.mp3'))

{
echo "YES";
}

?>

and it also just displays the title of the topic..??

[Virtualburn]

For example if the topic is 'M' the mp3 if present will be M.mp3

It's using bbpress post.php - This is the entire post.php page

<div class="old_threadauthor" style="float:left; position: relative; left:-120px; margin-right:-120px; width: 105px; text-align:center; overflow: hidden;">

	<?php post_author_avatar(); // // avatarupload_display(get_post_author_id()); ?>
	<small><?php post_author_title(); ?></small>
</div>

<div class="threadpost">

<div class="post"><?php post_text(); ?>	

<!-- START AUDIO -->

<!--
$filename = bb_uri() . 'bb-audio/'. topic_title().'.mp3';

[scrupul0us]

missing php tags and errors within the audio variable

[scrupul0us]

what happens if you echo:

if (file_exists($doc_root.'/bb-audio/M.mp3'))
{
     echo "YES";
} 

also keep in mind if you are on a *nix system the filenames are case sensitive vs the topic title
