unlink problem

[dangeorge6]

I need to be able to delete mp3s from a directory.  I'm using unlink like so:

 

unlink($path_to_delete);

[hitman6003]

Ok, so what's the problem?

 

Make sure that you have error reporting turned on....

 

ini_set("display_errors", 1);
error_reporting(E_ALL);

$myFile = "path_to_file/file.jpg";

unlink($myFile);

Jeez...half my post got cut for some reason

Here's the error:

Warning: unlink(http://MYURL/Beatles%20-%20It's%20Getting%20Better%20All%20The%20Time.mp3): No such file or directory in /var/www/web2/web/musicproject/php_scripts/functions.php on line 34

 

This link does exist, i've tried it with %20 and just spaces and same error.  Is this a permissions thing?  If so, how can I safely make this work?

try this it works ok first try the script in the same directory.

 

 

<?php

$file_to_unlink="delete_me.php";

if(unlink("$file_to_unlink")){

echo "$file_to_unlink deleted";
}else{

echo "sorry but the file $file_to_unlink has not been deleted!";
}

?>

You can't unlink a file that's a website...which is what it interprets the http:// to mean.  You have to give it a local path.

 

Use realpath:

 

http://www.php.net/realpath

thanks hitman.  Now I get a permission denied.  Perhaps this is out of the scope of the board.  But how do I give php permission to delete a folder on my apache server?  What's safest way to do this so I don't get hacked

[redarrow]

what on win linux what?

 

linux 777

 

win nothink as long as your the admin.

[dangeorge6]

i run apache on ubuntu linux.

 

how do you give delete privileges to specific folder on a website?

[hitman6003]

chmod 777 foldername

My PHP script refused to delete read-only files (which is probably a good thing), but I couldnt find out how to fix this on windows.

 

The solution is simple, i just replaced

<?php @unlink( $entry ); ?>

with:

<?php

               @chmod( $entry, 0777 );

               @unlink( $entry );

?>

 

chmod isnt supposed to work on windows, but 0777 seems to clear the read only flag, and 0444 seems to set the read only flag.

 

 

<?php

$file_to_unlink="delete_me.php";

@chmod( $file_to_unlink, 0777 );

if(@unlink("$file_to_unlink")){

echo "$file_to_unlink deleted";
}else{

echo "sorry but the file $file_to_unlink has not been deleted!";
}

?>

You may not want to have the "@" before your command names while you are testing...it will suppress any errors.

[dangeorge6]

works, you guys rock 

[utexas_pjm]

chmod 777 foldername

 

Depending on how sensitive the data is in the folder you might want to

 

% sudo chown apacheUser:apacheUser foldername -R

 

, where apacheUser := the user that your run you webserver as.

 

Best,
