[ngrmm]

how do i prepend home (root) to my rekursive menu
this is the original code from ryan

<?php
function treeMenu(Page $page = null, Page $rootPage = null) {

        if(is_null($page)) $page = wire('page');
        if(is_null($rootPage)) $rootPage = wire('pages')->get('/');

        $out = "\n<ul>";
        $parents = $page->parents;

        foreach($rootPage->children as $child) {
                $class = "level-" . count($child->parents);
                $s = '';

                if($child->numChildren && $parents->has($child)) {
                        $class .= " on_parent";
                        $s = str_replace("\n", "\n\t\t", treeMenu($page, $child));

                } else if($child === $page) {
                        $class .= " on_page";
                        if($page->numChildren) $s = str_replace("\n", "\n\t\t", treeMenu($page, $page));
                }

                $class = " class='$class'";
                $out .= "\n\t<li>\n\t\t<a$class href='{$child->url}'>{$child->title}</a>$s\n\t</li>";
        }

        $out .= "\n</ul>";
        return $out;
}

echo treeMenu(); 
?>

Try to replace the line

$out = "\n<ul>";

with this one:

$out = "\n<ul>\n\<li>\n\t\t<a href='{$rootPage->url}'>{$rootPage->title}</a>\n\t</li>";

(adding a class to the a element and modifying the \t tabs as needed).

thx ottogal
do you know how i could get rid of prepanding the parent through all levels? i just need it on the first level (Home-Button).

thanks adrian, but this doesn't work with 3- oder 4-level navigations

Have a look at this example for one way to do it. Create a third argument for your function, maybe called first. Use that to determine when to append 'Home'.

Of course it wouldn't work like I proposed since the function treeMenu() is called recursively...

So better try kongondo's example.

 

Or try to put the wrapping ul tag out of the function:

<?php
function treeMenu(Page $page = null, Page $rootPage = null) {

        if(is_null($page)) $page = wire('page');
        if(is_null($rootPage)) $rootPage = wire('pages')->get('/');

        $tree = "";
        $parents = $page->parents;

        foreach($rootPage->children as $child) {
                $class = "level-" . count($child->parents);
                $s = '';

                if($child->numChildren && $parents->has($child)) {
                        $class .= " on_parent";
                        $s = str_replace("\n", "\n\t\t", treeMenu($page, $child));

                } else if($child === $page) {
                        $class .= " on_page";
                        if($page->numChildren) $s = str_replace("\n", "\n\t\t", treeMenu($page, $page));
                }

                $class = " class='$class'";
                $tree .= "\n\t<li>\n\t\t<a$class href='{$child->url}'>{$child->title}</a>$s\n\t</li>";
        }

        return $tree;
}

$out = "\n<ul>\n\<li>\n\t\t<a href='{$rootPage->url}'>{$rootPage->title}</a>\n\t</li>";
$out .= treeMenu();
$out .= "\n</ul>";

echo $out; 

Note that I changed the local variable $out in the function to $tree. 

(I didn't test that myself...)

How about removing starting and ending UL's from the function and add it manually with the homepage link, like this (browser code!):

$menu = '<ul>' . '<li><a href="' . {$rootPage->url} .'">' . {$rootPage->title} . '</a> . '</li>' . treeMenu() . '</ul>';
