Is it possible to get all post variables in ExpressionEngine, like you could in CodeIgniter?

Try native

$this->input->post(NULL, TRUE); // returns all POST items with XSS filter $this->input->post(); // returns all POST items without XSS filter

php codeigniter post expressionengine

Ok, the way to get results similar to CI within EE for all elements of a POST, while still leveraging the security features of EE is the following:

foreach($_POST as $key => $value){     $data[$key] = $this->EE->input->post($key);}

Since you can access POST vars by name, looping through them in $_POST, then explicitly calling each will yield the desired result.
