Dynamic filters

By Taylor Luk
I found Filters are very useful, Adding a lot of filters with similar logic can be repetitive, Dynamic filters are a way to register a filter to a particular pattern, thus, making it more dynamic and reusable filters.

Example
implementing a lot of similar url filters like links_to can be as follow, i implemented the whole CRUD url filters in the same filter definition.

H2o::addFiler('links_to_(.*)', 'dynamic_link_to');
function dynamic_link_to($action, $input, $options) {
if (in_array(array(‘show’, ‘edit’, ‘delete’)))
{
$collection = Inflector::pluralize(strtolower(get_class($input)));
$url = “/{$collection}/{$action}/$input→id”;
// $url = Routes::for($input, $action);  # You may have a awesome router that generates url in you framework
}
elseif (preg_match(‘/create_(.*)/’, $action, $match))
{
$collection = Inflector::pluralize($match1);
$url = “/{$collection}/new”;
}
HtmlFilters::link_to($input, $url, $options);
}

// CRUD them all

{{ 'New post' | links_to_create_page }}

{{ page.title | links_to_show page }}

{{ 'New post' | links_to_edit page }}

{{ 'Delete post' | links_to_delete page }}
