path plug-in

[Haberman]

It would be nice to have a path plug-in. It would display the structure up to current page. For example:

Home -> Services -> Consulting

Any suggestions?

[haberman]

Also I need to know how to get page id and page parent id.

thank you...

Hi Haberman!

Take a look at the bulletmenu plugin (found in /plugins/function.bulletmenu.php)

It calls upon a standard function:

Code: Select all

	$content = db_get_menu_items($newparams);

db_get_menu_items returns an array of nested objects representing the entire menu hierarchy. You can then traverse it to plot the path to the current page.

To take a look at the structure db_get_menu_items returns, use the php var_dump function.

I'm not sure how to get the current page_id yet - if I find out, I'll post back.

[Manarth]

Thanks for the info goes to wishy...

Code: Select all

global $gCms; 
$thispage = $gCms->variables['page'];

This is the page_id of the current page.

[Manarth]

Seeing as I got started!

Note: This plugin requires at least revision 863 from subversion.
This is because it uses a new function called getURL (found in /lib/page.functions.php) to find out the URL of each page.

Code: Select all

Save this as 'functions.breadcrumbs.php' in your plugins directory.
Call it on a page or template using {breadcrumbs}.

Works in a template but not on a page. Am up to changeset 865.
htmlarea strips it out of the code

[Manarth]

HTMLAREA has issues

use the switch to go to 'source editing' mode.
the {breadcrumbs} tag should stay then.

Oh, there's no html tagging around the output, so you can add

Code: Select all

<p>{breadcrumbs}</p>

or similar to make it more presentable.

[Greg]

works until you do a preview or switch back to WYSIWYG.
Enclosing in a P tag worked, thanks.

[Manarth]

NP.

By the way, the version above is *already* old - so keep an eye on SVN: it should join the tree shortly. Hopefully, the latest version will always be found on SVN.

Ok, guys I see I started good topic. I was short on time so I started to work on it myself. And I did it. I was reviewing the bullet menu an write this code:

Code: Select all

global $db;
global $gCms;
$current_page = $gCms->variables['page'];

        # getting content
        $content = db_get_menu_items($newparams);
        
#variable definition
$separator = " / ";
$path = "";
$home = "";

# displays path up to 10 levels 
for ($i = 1; $i <= 10; $i++)
{        
 foreach ($content as $one) 
 {
        # searching current page
        if ($one->hier == 1) $home = '<a href="'.$one->url.'">'.$one->menu_text.'</a>';
        # searching current page
        if ($one->page_id == $current_page) 
                 {
                  $path = $separator.'<a href="'.$one->url.'">'.$one->menu_text.'</a>'.$path;
                  $current_page = $one->parent_id;
                  if ($current_page == 0) break;
                 }
 }
}
$path = $home.$path;
echo $path;

I don't know if its bullet proof, but it works on my version of CMS. To install it paste the code into plugin area and name it as you wish.

Enjoy
