Get parameters from referrer

Question

Is there a way to get the parameters from the referrer url?

I've tried this: {{ craft.request.urlReferrer.getQuery }} but that’s not working.

Answer 1

It can be done with some Twig code:

{% set referrer = craft.request.urlReferrer %}

{% if referrer %}
    {# Remove everything before the `?` #}
    {% set queryString = referrer|replace('/^.*\\?/', '') %}

    {# Split the query string into individual params #}
    {% set params = queryString|split('&') %}

    {% for param in params %}
        {# Split this param on the `=` sign #}
        {% set parts = param|split('=') %}
        {% set name = parts[0] %}
        {% set value = parts[1] is defined ? parts[1] %}

        {# Do something with it... #}
    {% endfor %}
{% endif %}

Note that this could would require Craft 2.2 or later, which comes with a regex-enabled replace filter.
