[Not Working]Do something when Input Button is submited

EDIT:Changed a few things

Hello.

simple Question:

how can i run a query or something when someone clicks on a button?

This is my stuff, but its not working

the controller:

Code:

//This displays friend requests, and i can approve them here
function show_requests()
{
    $query2 = $this->membership_model->get_requests($this->session->userdata('user_id'));
    $data['req'] = $query2;

    $data['action'] = site_url('site/process_req');
    $data['title'] = '';
    $data['sec_title'] = '';
    $data['main_content'] = 'view_req';

    $this->load->view('m_user_home',$data);    
        
}

//this processes the friend requests base on which button was clicked
function process_req()
{
    if($this->input->post('deny'))
    {
        redirect('site/show_users/','refresh');
    }
    elseif($this->input->post('accept'))
    {
        redirect('site/');
    }
}

The view:

Code:

<form action="<?php echo $action; ?>" style="display:block">
    <input type="submit" value="deny" class="butn rounded" name="deny"/>
           <input type="submit" value="accept" class="butn rounded" name="accept" />
</form>

What am i doing wrong?

User Guide.

[eluser]flyenig[/eluser]
yes ive read the user guide. but i cant find what im looking for

Look again at the Controllers page. It will reveal how to use the URI to pass parameters to the controller. Then look at the URI Class to see various ways to access the URI parameters

You are missing key knowledge on how this whole game works. Maybe start here http://www.w3schools.com/php/php_forms.asp

[eluser]flyenig[/eluser]
im not new to php, im just new to the forums, and ive been working with codeigniter for a while now, its just this simple thing that i do not get.

Like everytime i click on, for example, deny, it takes me to a blank page with the url

http://localhost/www/cl/index/site/process_req?

Didn't claim you were new to anything, just missing a lot of pieces. You might be able to program a lunar mission in PHP, but I just recognize that you are missing very basic Web development fundamentals. First, your buttons contain no "name" attributes. Look at the HTTP Request you are sending and you'll see the problem that causes. And I don't know what your $action variable contains, but whatever is there is why your form is going where it is going.

Ok I appologize,
I didn't put enough of my code on here and yea wow I forgot the name attributes lol
