handle segments with in controller class in codeigniter 2.1 - php

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');
}

Answer 2

class Blog extends CI_Controller{
function __construct(){
parent::__construct();
}
// Now See
function _remap( $method ){
switch( $method ){
case 'about':
$this->about(); <---------- here method (Add header, content, footer inside respective functions)
break;
case 'login':
$this->login(); <------- here too
break;
case 'services':
$this->service(); <----- here too
break;
}
}
}//Close Class
what you have done here is, you overrided the default behavior of URI by _remap function.
The overridden function call (typically the second segment of the URI)
will be passed as a parameter to the _remap() function:
Simply, in most cases, the 2nd segment will become $method in the _remap function.
so your form action will become.
action = "<?php echo base_url('blog/login');?>"
add index.php if you haven't removed index.php from your url by htaccess.
EDIT:
As per your question,
but now don't know how to handle both segment like login and login/getLog .
this is how you deal.
Any extra segments after the method name are passed into _remap() as an optional second parameter.
public function _remap($method, $params = array())
{
// all other segments will be in $paramas array
}
