Provides a twig filter for modifying query strings from within twig templates.
- Move the
querystringfolder into yourcraft/pluginsdirectory - Install the plugin in the Craft Control Panel
A common problem I run into with Craft is the desire to do two-dimensional filtering via query string parameters, but trying to update or modify them in pure twig templating code is a pain.
This plugin, with use of the craft url tag, makes this much easier.
First, get the Query object from Craft. Then invoke the querystring filter, which accepts and array of key value pairs to add/update the query string.
{% set query_string = craft.request.getQuery() %}
{{ url(craft.request.url, query_string|querystring({'event_type': 'party', 'event_start_date': '2016-12-30'})) }}
will generate a URL like: http://example.com/path/to/page?event_type=party&event_start_date=2016-12-30
If a parameter key already exists, it will replace the value with the new value.
{{ url(craft.request.url, query_string|querystring({'event_type': 'quinceanera'})) }}
yields: http://example.com/path/to/page?event_type=quinceanera&event_start_date=2016-12-30
To remove a parameter, pass in an empty value:
{{ url(craft.request.url, query_string|querystring({'event_start_date': ''})) }}
yields: http://example.com/path/to/page?event_type=quinceanera
