need logic help...unordered list from array

[nikefido]

I have some javascript that uses unordered lists to make a collapsing file structure...so i need an unordered list to be in a certain format.

It needs to start and end with a UL /UL (duh). Each Folder is a LI and each file is a LI of a sub-UL.

 

my function:

<?php
function print_array($a, $n=0) {
	//echo "<li>\n";
	//echo "</ul>\n";
	$first = true;
	foreach ($a as $key => $value) {
		  if (is_array($value)) {
		  if($n != 0) {echo "</ul>\n</li>\n";}
		  $n++;
			echo "<li><a href=\"#\">Folder</a>\n";
			$first = true;
			$this->print_array($value, $n);
		  } else {
			if($first) echo "<ul>\n";
			$first = false;
			echo "<li><a href=\"#\">File</a></li>\n";
		  }
		}

?>

 

This prints out a UL that is does show imbedded/sub directories (they are all on the same level!)

However, the folder structure is like this:

Folder1

  SomeFile1.0.1

  Folder1.5

      Somefile1.5.1

 

Folder2

  SomeFile2.0.1

  Folder2.5

      SomeFile2.5.1

 

Folder3

  SomeFile3.0.1

 

 

What am I missing here?

post the output from

 

var_export($a);

 

so we can see what the input array looks like

I wrote the following, see if it does what you want:

<?php
$ary = array('L1' => 'L1',
		     'L2' => array('L2.1' => 'L2.1',
				 	  'L2.2' => 'L2,2',
					  'L2.3' => array('L2.3.1'=>'L2.3.1',
								  'L2.3.2'=>'L2.3.2'),
					  'L2.4'=>'L2.4'),
		     'L3' => 'L3');
function ul($a) {
	foreach ($a as $k => $v) {
		echo '<li>' . $k;
		if (is_array($v)) {
			echo '<ul>'."\n";
			ul($v);
			echo '</ul>'."\n";
		}
		echo "</li>\n";
	}
}
        echo "<ul>\n";
ul($ary);
        echo "</ul>\n";
?>

 

This produces

    * L1
    * L2
          o L2.1
          o L2.2
          o L2.3
                + L2.3.1
                + L2.3.2
          o L2.4
    * L3
