Argument Picker is a simple API to access and elaborate arguments in a flexible way.
Basically it allows, given URL arguments like:
example.com/myview/make:Volkswagen/model:Polo/year:2008/
to retrieve one of those arguments through a function:
arg_picker_get_selector_argument("make")
which - in the specific example - would return "Volkswagen".
This module essentially adds the possibility to assign labels to arguments, through this syntax:
www.example.com/your_view/LABEL1:ARG1/LABEL2:ARG2/LABEL3:ARG3
and then allows you to retrieve any argument using the label as a reference.
Some of the helper functions are dedicated to specific modules (i.e. Views), enhancing the accessibility of arguments:
www.example.com/your_view/something/bar:1/foo:4/other/parameters
Assuming "your_view" has a "foo" argument, using argument_picker, you could easily setup this argument's default value with:
<?php
return arg_picker_get_view_argument("foo");
?>
which would return "4" (for the example above) or "all" (when the argument is not present).
DDEV is the official local development tool of Drupal. And like Drupal, DDEV depends on the support of the open source community.
