Mythological EE Actions Table

exp_actions contains rows of class + method combinations, which are called directly in index.php.

Take for instance this row:

action_id | class  | method 
8         | Member | registration_form

If you look at the EE standard registration you’ll most likely find that it is posting do /index.php?ACT=8

This means it is posting to action_id 8, which is referring to class “Member” and method “registration_form” (mod.member.php:registration_form()

Makes sense?

Yes that makes sense.

What I am after is a method in the mod file that will create the form or form template tags and then handle the post data. So I am thinking something like this:

function test()
{
    $go_to = $this->EE->TMPL->fetch_param('go_to');
    
    $base_url = $this->EE->functions->fetch_site_index(0, 0).QUERY_MARKER.'ACT='.$this->EE->functions->fetch_action_id('Module', 'test');
    
    $this->EE->load->helper(array('form', 'url'));

    $this->EE->load->library('form_validation');
    
    $this->EE->form_validation->set_rules('test', 'lang:my_lang', 'required');
    
    if ($this->EE->form_validation->run() == FALSE)
    {
        // would need to actually create tagdata and options.
        $output = $this->EE->TMPL->parse_variables($this->EE->TMPL->tagdata, $variables); 
        return $output;
    }
    else
    {
        // Update the db and redirect to other theme.
        redirect($go_to);
    }
}

I am getting the logic right?

Yepp, you can do it like that, but there is a $this->EE->functions->form_declaration() method you can use also.

Have a look at mod.member_register.php and the registration_form() function.

btw I prefer having one method to create the form tag (e.g. {exp:mymodule:create_form}) and then another one that will recieve the form submission (listed in exp_actions).
