only including certain file types

displaying certain file types when displaying contents of dir?

[yt404]

i have this code which i have taken from php.net and am hopin to have someone tell me how i could modify it to display only one file type (.mid) also this is to stop the script from displaying other directorys as they will automatically load up the index of that directory and won't display a list.

can anyone help out?

here's the code:

<?
$the_array = Array();
$handle = opendir('/home/www/juttuffi/midi/files');
while (false!== ($file = readdir($handle))) {
if ($file!= "." && $file!= "..") {
$the_array[] = $file;
}
}
closedir($handle);
sort ($the_array);
reset ($the_array);
while (list ($key, $val) = each ($the_array)) {
echo "<a href=http://example.co.uk/midi/files/$val target=_blank>$val</a><br>";
}
?>

well you could just expand your test here

if ($file!= "." && $file!= "..") {
$the_array[] = $file;
}

so we don't want directories in the array?
!is_dir($file)

and we want to test the file extension to see if it is .mid

$namearr = split('.',$file);
if ($namearr[count($namearr)-1]!= 'mid')

makes sense, so how do we add it

if ($file!= "." && $file!= ".." &&!is_dir($file)) {
$namearr = split('.',$file);
if ($namearr[count($namearr)-1]!= 'mid') $the_array[] = $file;
}

might even work, I sure didn't test it ;)

nah it had no effect, the link shows that the directory "test" and the .gif file are still visible, heres the code i used.

<?
$the_array = Array();
$handle = opendir('/home/www/juttuffi/midi/files');
while (false!== ($file = readdir($handle))) {
if ($file!= "." && $file!= ".." &&!is_dir($file)) {
$namearr = split('.',$file);
if ($namearr[count($namearr)-1]!= '.mid') $the_array[] = $file;
}
}
closedir($handle);
sort ($the_array);
reset ($the_array);
while (list ($key, $val) = each ($the_array)) {
echo "<a href=http://example.co.uk/midi/files/$val target=_blank>$val</a><br>";
}
?>

i used it as ",mid" and "mid" no effect mate, im not gettin any errors mind so maybe its just the cache, ill check it in an hour but nah no effect. Cheers for the help man

my fault, i made 2 mistakes (i tested it now)

<?
$the_array = Array();
$handle = opendir('/home/www/juttuffi/midi/files');
while (false!== ($file = readdir($handle))) {
if ($file!= "." && $file!= ".." &&!is_dir($file)) {
$namearr = split('\.',$file);
if ($namearr[count($namearr)-1] == 'mid') $the_array[] = $file;
echo "<p>$file<br><pre>";
print_r($namearr);
echo "</pre>";
}
}
closedir($handle);
sort ($the_array);
reset ($the_array);
while (list ($key, $val) = each ($the_array)) {
echo "<a href=http://example.co.uk/midi/files/$val target=_blank>$val</a><br>";
}
?>

forgot to escape the . in the split and had!= 'mid', it would make a lot more sense as == 'mid' ;)
