Hi,
I'm trying to make my tree menu display properly but it's driving me a little bit nuts!

Basically I have the following code that produces a nested tree structure for pages in my cms:

 test.php

It is supposed to render as follows:

>Home
   - Spiders Attack!!!
      - About Page
   - Page Four Link
>HWRCs

but instead renders like this page (out of alignment)

http://dev.netbridge.co.uk/admin/test.php

I can of course supply css and extra code if it would help solve my problem, and I would really appreciate it if you could help in any way.

Thanks,

owennicol

The issue is in function build_child()

for ( $c=0;$c<$depth;$c++ )            // Indent over so that there is distinction between levels
{
$tempTree .= '<div class="test">';
}

Open in new window

which adds a div with a 20 pixel margin on the left depending on the depth, however the entire row is put within the div instead of just the left hand button.

To fix this you somehow need to just appy the margin to enclose this code
<span><a class="sexybutton sexysimple" href="edit_page.php?pid=' . $pid . '"><span class="book">' . $linklabel . '</span></a></span>

Open in new window


as shown below
function build_child($oldID)            // Recursive function to get all of the children...unlimited depth 
{ 
    global $exclude, $depth;            // Refer to the global array defined at the top of this script 
	include("../scripts/connect_to_mysql.php");
    $child_query = mysqli_query($myConnection,"SELECT pageorder, id, linklabel, pagetitle, showing, navigation, date_format(lastmodified,'%e/%c/%Y') as formattedDate FROM pages WHERE parent_id='$oldID' ORDER BY pageorder ASC" ); 
    while ( $child = mysqli_fetch_array($child_query, MYSQL_ASSOC) ) 
    {
		$pid = $child["id"];
		$linklabel = $child["linklabel"];
		$pagetitle = $child["pagetitle"];
		$pageorder = $child["pageorder"];
		$parent_id = $child["parent_id"];
		$showing = $child["showing"];
		$date = $child["formattedDate"];
		if($showing=='0'){ $show =  '<img src="../style/SexyButtons/images/icons/silk/cross.png" width="16" height="16" alt="cross" />';} else { $show = '<img 	src="../style/SexyButtons/images/icons/silk/tick.png" width="16" height="16" alt="tick" />';}
		$navigation = $child["navigation"];
		if($navigation=='0'){ $nav =  '<img src="../style/SexyButtons/images/icons/silk/cross.png" width="16" height="16" alt="cross" />';} else { $nav = '<img src="../style/SexyButtons/images/icons/silk/tick.png" width="16" height="16" alt="tick" />';}
        
		
		if ( $pid != $parent_id ) 
        { 	
			
			
				
			$tempTree .= '<li id="recordsArray_' . $pid . '"><span class="label">";

for ( $c=0;$c<$depth;$c++ )            // Indent over so that there is distinction between levels 
            { 	 			
				$tempTree .= '<span class="test">';  				 
			} 
$tempTree .= "<a class="sexybutton sexysimple" href="edit_page.php?pid=' . $pid . '"><span class="book">' . $linklabel . '</span></a></span></span>
	<span class="delete"><span style="padding-top:3px;"><a class="sexybutton sexysimple" onclick="confirmation()"><span class="cancel">Delete this page</span></a></span></form></span>
	<span class="nav" ><span style="padding-top:3px;">' . $nav . '</span></span>
		<span class="live" ><span style="padding-top:3px;">' . $show . '</span></span>
	<span class="order"><span style="padding-top:3px;">Drag</span></span>
	<span class="mod"><span style="padding-top:3px;">' . $date . '</span></span></li>';
			
            $depth++;        // Incriment depth b/c we're building this child's child tree  (complicated yet???) 
			$tempTree .= build_child($pid);        // Add to the temporary local tree 
			$depth--;        // Decrement depth b/c we're done building the child's child tree. 
            $tempTree .= '</div>';
			array_push($exclude, $pid);            // Add the item to the exclusion list 
			
        } 
    }  
   
    return $tempTree;        // Return the entire child tree 
}
