ID3 Tags

[acondiff]

I have a script that looks in a folder for mp3 files and gets the id3 data for each one. There are certain files though that it cannot read. I checked one it can read and one that it can't and both have the same id3 version and are both encoded with iTunes. Does anyone know what is wrong here?

Here is my script.

<?php 
					if ($dir = opendir( TEMPLATEPATH . "/flash/music/" )) {  

    					$files = array();
    					while (false !== ($file = readdir($dir))) {   

							$files[] = $file;
    					}  

    					sort($files);            					

					foreach($files as $file) {
						if ($file != "." && $file != "..") {   
							$myfile = TEMPLATEPATH . "/flash/music/" .$file; 

							$musicfile =  fopen($myfile, 'r');
	        					fseek($musicfile, -128, SEEK_END);

   		     				$tag = fread($musicfile, 3);

      		  				if($tag == "TAG") {
        						$data["song"] = trim(fread($musicfile, 30));
        						$data["artist"] = trim(fread($musicfile, 30));
        						$data["album"] = trim(fread($musicfile, 30));
        						echo "<tr>";
							echo "<td><div class=\"ui360\" style=\"float:left;display:inline;margin-right:16px\"><a href=\"";?><?php bloginfo('template_directory'); ?><?php echo "/flash/music/".rawurlencode($file)."\" title=\"360 demo: Angry Cow Sound\" class=\"norewrite exclude button-exclude inline-exclude\"></a></div></td>";
        					echo "<td>" . $data["song"] . "</td>";
        					echo "<td>" . $data["artist"] . "</td>";
        					echo "<td>" . $data["album"] . "</td>";
        					} else {

        					echo "<tr>";
							echo "<td><div class=\"ui360\" style=\"float:left;display:inline;margin-right:16px\"><a href=\"";?><?php bloginfo('template_directory'); ?><?php echo "/flash/music/".rawurlencode($file)."\" title=\"360 demo: Angry Cow Sound\" class=\"norewrite exclude button-exclude inline-exclude\"></a></div></td>";
        					echo "<td></td>";
        					echo "<td></td>";
        					echo "<td></td>";

        					}	

	            			fclose($musicfile);

							echo "<td><a href=\""; ?><?php bloginfo('template_directory'); ?><?php echo "/flash/music/".rawurlencode($file)."\">$file</a></td>";

							echo "<td>
							<form action=\"#\" method=\"POST\">
							<input type=\"hidden\" name=\"filename\" value=\"$file\">
							<input type=\"hidden\" name=\"delete\" value=\"true\">
							<input type=\"hidden\" name=\"_submit_delete_check\" value=\"1\"/> 
							<input type=\"submit\" value=\"Delete\">
							</form>
							</td>
							";
							echo "</tr>";
	   	 				}   

					}
				}  
			?>

How are you sure that the tags on the MP3s are ID3 v1 tags and not a later version? I don't remember iTunes showing both. WinAmp, when you right click and do 'view file info', does explicitly show you the ID3 v1 tags.

The final totally explicit way to check one of these files (this works) is to open it up in Windows WordPad. Scroll down to the very end of the file and the end of the final line and make sure you can see the data you're expecting.

What are the MP3s that don't show? Do their names contain strange fonts or something?

Basically if this is only failing on a few MP3s I'd be checking the binary data on those MP3s now. 🙂

It seems like its either the newer version of iTunes or the Channels...i dont know though. I am actually on a mac but how do I check the binary data? These ones that wont work right are purchased from the iTunes store and then converted into MP3's with iTunes. Apparently older version worked??? Is there anything in my script that I can modify to make this work?

[acondiff]

I figured it out, well why its not working. The ones that work, when opened up in a text editor have something like this at the bottom:

TAG01 Let Go

[acondiff]

Hmm...it didn't post the last part of my post. Probably because it had weird characters in it.

But when I open a file that doesn't work in a text editor it doesn't have the id3 tags at the bottom. They are at the top, but each tag is divided by some weird code.

ID3

[acondiff]

I give up. It keeps cutting my posts short. I didn't have any special characters that time. oh well.

[acondiff]

So "ID3

[acondiff]

is at the top. TT2 is before the title. TP1 before the artist. TAL before the album. sorry but these this forum has problems.

[TheoGB]

Yeah, the ones that aren't working don't have ID3 v1 data. As I said in your other thread, you're not reading v2 data in this code.

You'll have to find some way to put ID3 v1 data into the MP3s or find the details for reading the ID3 v2 tags. For the former maybe check iTunes to see if there is a check box to tick in the settings or something that copies them across.

[acondiff]

well I just found this script and tried to integrate it with my code. here is my new code. i am getting a unexpected echo though. where should i echo out the html? here it is:

ignore that last post. this is the code. but I am getting this error:
Parse error: syntax error, unexpected '}' in /[path]/id3.php on line 59

I cant figure it out. I have looked over it 10 times and it looks good to me. do you see anything?

Can you be a bit more specific about the 'unexpected echo'?

[TheoGB]

Oh right, you put a second post in.

I can't see the missing } that's for sure.

I tried putting it into Aptana but I wasn't getting the syntax checker pulling up anything.

Still, if you don't already use it, then try running it:
http://www.aptana.com/products/studio2/download

It's invaluable for doing PHP stuff, in my view.

[acondiff]

Hmm...got it so it doesn't return any errors, but all its doing is echoing either a 2 or a 1 instead of the tags. Any ideas?
