Can you change $_POST into something different

Question

I made two separate databases for my posts, one for article and one for review.

My two database tables, are basically the same.

CREATE TABLE IF NOT EXISTS `post` (
`post_id` int(11) NOT NULL,
  `post_title` varchar(25) NOT NULL,
  `post_text` varchar(500) NOT NULL,
  `post_img` varchar(255) NOT NULL,
  `post_pic` varchar(255) NOT NULL
) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=latin1;

For articles I used controller:

 function index_ajax()
    {
        echo "\$_POST:<br>";
        var_dump($_POST);
    }
    function index_post()
    {
        echo "\$_POST:<br>";
        var_dump($_POST);
        $data = $_POST['data'];
        $data['post_id'] = $this->params[0];
        insert('post', $data);
    }

Now I needed make basically same for review posts.

function index_ajax()
    {
        echo "\$_REVIEW :<br>";
        var_dump($_REVIEW);
    }

    function index_review()
    {
        echo "\$_REVIEW:<br>";
        var_dump($_REVIEW);
        $data = $_REVIEW['data'];
        $data['review_id'] = $this->params[0];
        insert('review', $data);
    }

The articles are going nicely into database, but the same method wont work for reviews.

I did change in my form from <form class="form-inline" method="post" role="form"> to <form class="form-inline" method="review" role="form">

I have kind of feeling it wont just work for it

I heard it should work, but it doesn't actually. I am grateful for new tips and ideas.

Thank you!

Update. For someone who reads this in future.

 function index_ajax()
    {
        echo "\$_POST:<br>";
        var_dump($_POST);
    }
    function index_post()
    {
        echo "\$_POST:<br>";
        var_dump($_POST);
        $data = $_POST['data'];
        $data['review_id'] = $this->params[0];
        insert('review', $data);
    }

The method is the http request type. 'Get' is for just getting the data from the page whereas 'post' is submitting data to the page.

Read this. and this

Data submitted to the page is always going to live inside $_POST.
