Views Contextual filter: php code for getting the value from url

Question

Im trying to set up a Contextual filter in drupal views based on the URL.

The contextual filter is operating with a text field that sets the node alias.

I have it working with "RAW value from URL" based on the position (parentpage/childpage/grandchild-page), but the position could change (only parents and child for example), so do i need to use the "PHP code", or is there a better way?

What i want to happen:

"If last section of page url, (grandchild-page), matches field set in contextual filter, then true (show fields).

Answer 1

Though the solution you have implemented worked but my suggestion is to use the request_uri() instead of the $_SERVER['REQUEST_URI'] because of the following reasons:

• $_SERVER['REQUEST_URI'] is only available on Apache, whereas request_uri() generate an equivalent using other environment variables.
• Apache does nothing by default to sanitize the $_SERVER variables so directly using it without passing through the check_plain should be considered unsafe.

So its better to get the URL like this:

$current_url = check_plain(request_uri());

Example: if the url is http://www.example.com/param1/param2/param3 than the $current_url will contain /param1/param2/param3.

Rest you can build the logic to get the last params, there are numerous ways of doing that.

You do not have to use PHP code - there is a module for that: https://www.drupal.org/project/views_contextual_filter_query

OR you could use Context: https://www.drupal.org/project/context_query_param

Thank you J. Reynolds for pointing me in the right direction!

I have used the following in "When the filter value is NOT available > provide a default argument > PHP Code"

$url = $_SERVER["REQUEST_URI"];
$url_path = parse_url($url, PHP_URL_PATH);
$basename = pathinfo($url_path, PATHINFO_BASENAME);
return $basename;

($basename is matching the last segment of the URL which is set via pathauto from a custom pseudo title field on my content type, and this field is also used the operational contextual filter in Views.)

EDIT: I also have a Relationship "Content referencing Content from field_related_products" that is selected in the contextual filter.

Please refer to the answer from Ankit Agrawal for a better way to retrieve the URL
