Access POST data to conditionally display form

Question

I'm working with the contact form plugin and would like to test for post data to see if the form was just submitted.

It seems this code always throws a template error.

Variable "test" does not exist

Is there a better way to do this?

{% set success = craft.request.getPost(test) %}
{% if success %}
    form was just submitted
{% endif %}

Answer 1

I think you want this:

{% set success = craft.request.getPost('test') %}
{% if success %}form was just submitted{% endif %}

Pass a string to getPost()

Answer 2

If you just want to test if something is in POST, and don't care what it is, then this should work:

{% set success = craft.request.getPost() | length %}

{% if success %}
    form was just submitted
{% endif %}
