Question

i am stuck in segments in codeigniter because it is new to me,
the problem with my login form.

i gave the url in action like action="blog/login/getLog" and
my login form shows in the url like blog/login

i know that in controller class i just create a function like with the name login but i created my controller file like this:

class Blog extends CI_Controller{
function __construct(){
    parent::__construct();
}

// Now See
function _remap( $method ){
    $this->load->view('header');

    switch( $method ){
        case 'about':
            $this->load->view('about');
            break;
        case 'login':
            $this->load->view('login');
            break;
        case 'services':
            $this->load->view('service');
            break;
    }

    $this->load->view('footer');
}
}//Close Class

but now don’t know how to handle both segment like login and login/getLog .

EDIT: What happen exactly, when i click on the login button then i just see the login form according to _remap() and the url like blog/login and when i submitted the form and the url looking like blog/login/getLog, the login form still looking but i want to redirect it on success.. or want to detect the segment getLog if possible in the case 'login': if possible.

Thanks in advanced.

Answer 1

If you are sending through the URL, just use uri class:

$var = $this->uri->segment(3);

If you are sending in a form, send the variable through the form. Perhaps a hidden field?

$var = $this->input->post('var_name');

Edit: I’m not quite sure why you are using _remap for this w/o routing to another function (you are only trying to call a view file instead)

This is how I would expect to see the login form:

<?php echo form_open('blog/login');?>
<input type="hidden" name="getLog" value"true" />
<input type="submit" value="Login" />
</form>

Then in your Blog class i would rather put a function

public function login() {
    if($this->input->post('getLog') === "true") {
        //the form was submitted, let's check the login?
    }
    else {
        //probably don't need an else, but form isn't submitted
    }
}

Edit 2:

In case there are confusions and you actually want to use remap. You can do it like this to get the variables also.

function _remap( $method ) {
  if ($method == ‘something’) {
     $this->something();
  } 
  else {
      $this->somethingelse();
  }
}

function something() {
  $var1 = $this->uri->segment(3);
  $var2 = $this->input->post('some_variable_name');
}
