Change value of variable using URL

Hi,

I'm using this setup to populate $navgroup with a value from the URL.

$page_url = perch_page_url(['include-domain' => false,], true); // Output the full URL of the current page
$dir_name = dirname($page_url); // Returns a parent directory's path  
$navgroup = str_replace('/','', $dir_name); // Replace all occurrences of the search string with the replacement string  
print $navgroup;

It only half works, here are some examples:

Example 1: site.com/de/demo/

$navgroup has a value of de when I visit the demo page. This is what I want to happen.

Example 2: site.com/de/

$navgroup has a value of / when I visit the de page

I need it to have a value of de

Example 3: site.com/de/demo/test

$navgroup has a value of demo when I visit the test page

I need it to have a value of de

Wherever the user is on the de branch, I'd like $navgroup to output de

What's the best way to achieve this?

I'm trying to get this to work so I can use $navgroup to change the main navigation on a multi-language website.

Using something like this:

perch_pages_navigation(['navgroup'=> $navgroup]); // output navgroup based on value of $navgroup

So is the value you want always the first url segment?

Hello Stephen,

Assuming you only get the URL this way:

$page_url = perch_page_url(['include-domain' => false,], true);

So the value of $page_url doesn't include https://, you could use something like this:

$url_parts = explode("/", $page_url);
$lang = $url_parts[1];

Great stuff, thanks Hussein.

I'm working on a multi-language website (using the branching technique), and was looking for a way to use part of the url as a variable

Putting it all together, here's what I'm using change the navgroup based on the current language branch. I've also used set_var so I can use $nav_group in my html templates.

$page_url = perch_page_url(['include-domain' => false,], true); // Output the URL of the current page, minus http
$url_parts = explode("/", $page_url); // Split a string by a string
$nav_group = $url_parts[1]; // Output the first part of string 
PerchSystem::set_var('lang', $nav_group); // Set 'lang' for use in html templates
perch_pages_navigation(['navgroup'=> $nav_group]); // Output navgroup based on value of $nav_group
// print $nav_group; // Test output value of $nav_group

In Runway you can also grab the segment from the route using perch_get().

Hi Drew,

I'm curious, how would I grab the segment from the route using perch_get()?

It's usually perch_get(0), or you can name it in your route. The routing values are always displayed in the debug for a routed page.
