[SOLVED] List all subdirectories in a folder, then list the contents of each one separate

[DaveLinger]

So what I'm trying to do is scan a directory "maps" for subdirectories (which will be used as categories). At the top of the page, I want to list the "categories", with anchor links/bookmark links (#these) to the part of the page (below) that lists that category's contents. I've got it all working EXCEPT that it only lists the contents of the FIRST category, then stops.

 

echo "<div class=\"box\">
<div class=\"box1\"><h2>Map Categories</h2></div>
<div class=\"box2\">";

$dirpath = "games/{$gameid}/maps/";
$dir = opendir($dirpath);
while (($filename = readdir($dir)) !== false){

if($filename != "" && $filename != "." && $filename != ".."){
if(strpos($filename, ".") === false){
echo "<a href=\"#{$filename}\">{$filename}</a> ";
}
}
}

echo "</div></div><br />";

$dirpath = "games/{$gameid}/maps/";
$dir = opendir($dirpath);
while (($filename = readdir($dir)) !== false){

if($filename != "" && $filename != "." && $filename != ".."){
if(strpos($filename, ".") === false){

echo "<div class=\"box\">
<div class=\"box1\"><h2>{$filename}</h2><a name=\"{$filename}\"></a></div>
<div class=\"box2\">
	<ul>";

$dirpath = "games/{$gameid}/maps/{$filename}/";
$dir = opendir($dirpath);
while (($filename1 = readdir($dir)) !== false){

if($filename1 != "" && $filename1 != "." && $filename1 != ".."){
if(strpos($filename1, ".") === false){

echo "<li><a href=\"{$filename1}\">{$filename1}</a></li>";

}
}
}

echo "</ul>
</div></div>";

}
}
}

 

Example output:

 

<div class="box1"><h2>Map Categories</h2></div>

<div class="box2"><a href="#World 8">World 8</a> <a href="#World 2">World 2</a> <a href="#Miscellaneous">Miscellaneous</a> <a href="#World 1">World 1</a> </div></div><br /><div class="box">
<div class="box1"><h2>World 8</h2><a name="World 8"></a></div>
<div class="box2">
	<ul></ul>
</div></div>

While you are looping through $dir (while (($filename1 = readdir($dir)) !== false) ), you cannot reassign $dir. The inner loop needs a new variable ($dir2?). You are, in essence, stepping on your own variables.

Ah, indeed. Good call. That fixed that. But apparently it's also not listing the files in each category, as if the folder is empty.

 

My new code:

 

echo "<div class=\"box\">
<div class=\"box1\"><h2>Map Categories</h2></div>
<div class=\"box2\">";

$dirpath = "games/{$gameid}/maps/";
$dir = opendir($dirpath);
while (($filename = readdir($dir)) !== false){

if($filename != "" && $filename != "." && $filename != ".."){
if(strpos($filename, ".") === false){
echo "<a href=\"#{$filename}\">{$filename}</a> ";
}
}
}

echo "</div></div><br />";

$dirpath = "games/{$gameid}/maps/";
$dir = opendir($dirpath);
while (($filename = readdir($dir)) !== false){

if($filename != "" && $filename != "." && $filename != ".."){
if(strpos($filename, ".") === false){

echo "<div class=\"box\">
<div class=\"box1\"><h2>{$filename}</h2><a name=\"{$filename}\"></a></div>
<div class=\"box2\">
	<ul>";

$dirpath1 = "games/{$gameid}/maps/{$filename}/";
$dir1 = opendir($dirpath1);
while (($filename1 = readdir($dir1)) !== false){

if($filename1 != "" && $filename1 != "." && $filename1 != ".."){
if(strpos($filename1, ".") === false){

echo "<li><a href=\"{$filename1}\">{$filename1}</a></li>";

}
}
}

echo "</ul>
</div></div><br />";

}
}
}

Whoops, nevermind, I found the error. It was looking for directories again, instead of files. (was looking for files without a "." in their name)
