problems with readdir and sort

pixelfighters

i have a problem with sorting my readdir results. a directory should be opened and read, and only jpg files, not starting with thumb or medium should be returned.

this works fine, and also a standalone readdir script i have written works fine, and sorts the results alphabetically. but i can't manage to combine those two.

i am afraid it is just a silly problem, but i feel like im blinded :-(

perhaps someone can give me a clue. here is the code where i still have included the wrong sort():

<?php
//** DIRECTORY LISTING UND AUSGABE
chdir("/home/www/web671/html/foto/images/fotos/");
$mydir = getcwd();
$hdl = opendir($mydir);
echo "<font>";
echo"<span class='bold'>Foto: </span>(Directory: ",$mydir.")<br>\n";
echo"<select name='image' size='1'><option value='$bildname'>",$bildname.".jpg</option>\n<option>----------------------no image---------------------</option>\n";
while ($file = readdir($hdl))
sort($file);
{
if (ereg("medium" , $file)):
{
} else: {
if (ereg("thumb" , $file)):
{
} else: {
if (ereg(".jpg$" , $file)):
{
$file=ereg_replace (".jpg","", $file);
echo "<option value='",$file."'>",$file.".jpg</option>\n";
} else: {
} endif;
} endif;
} endif;
}
rewinddir($hdl);
echo "</select></font>";
closedir($hdl);

?>

thanks for reading and greetings

The obvious solution would appear to be: don't combine them, then 🙂 No joke: you can't properly sort() an array until you've got an array to sort because you don't know where the next filename should go; when you get it you'll just have to sort() again anyway to get the next filename into the right place. As it happens, you don't have an array at all; you're trying to sort a string.

//** DIRECTORY LISTING UND AUSGABE
chdir("/home/www/web671/html/foto/images/fotos/");
$mydir = getcwd();
$hdl = opendir($mydir);
$files=array();
while ($file = readdir($hdl))
{	if(preg_match("/\.jpg$/",$file) && !preg_match("/medium|thumb/",$file))
		$files[] = preg_replace("/\.jpg$/",$file);
}
closedir($hdl);
sort($files);
echo "<font>";
echo"<span class='bold'>Foto: </span>(Directory: ",$mydir.")<br>\n";
echo"<select name='image' size='1'><option value='$bildname'>",$bildname.".jpg</option>\n<option>----------------------no image---------------------</option>\n";
foreach($files as $file)
{	echo "<option value='",$file."'>",$file.".jpg</option>\n";
}
echo "</select></font>";
closedir($hdl);

PS: vBulletin's syntax colouring doesn't like regexps: that's .jpg
