Use same function for both 'add' and 'edit' in Codeigniter? - codeigniter

Question

I want both these urls:
/admin/users/add
and
/admin/users/3/edit
to point to edit($user_id = 0) function in my users controller. The number 3 in the second url has to be passed to the $user_id parameter.
How can I do this in a smooth way?

Answer 1

By setting up a route in application/config/routes.php:
$route['admin/users/add'] = "users/edit";
$route['admin/users/(:num)/edit'] = "users/edit/$1";
If you want this to work for other controller too, you can do this:
$route['admin/(:any)/add'] = "$1/edit";
$route['admin/(:any)/(:num)/edit'] = "$1/edit/$2";
Or the same, using regular expressions:
$route['admin/([a-z]+)/add'] = "$1/edit";
$route['admin/([a-z]+)/(\d+)/edit'] = "$1/edit/$2";

Answer 2

As an alternative to separate your logic.
I generally have two controllers that both speak to the same view.
admin/user/add
admin/user/edit/3
Both point to the view
admin/user_form.php
Which then access a save_user() method when the form has been posted.
But as Mischa said, by setting up routes you can point pretty much any url to any method.

Answer 3

Can you do this
public function users ($type, $id = null)
{
if ($type === 'edit')
{
// do edit stuff
}
else
{
// ad add stuff
}
}

Sulotion:
function _remap($method)
{
$param_offset = 2;
// No method, point to...
if (!method_exists($this, $method))
{
if (is_numeric($method) || $method == 'add')
{
// Show single
$param_offset = 1;
$method = 'show';
}
else
{
// Index
$param_offset = 1;
$method = 'index';
}
}
// Since all we get is $method, load up everything else in the URI
$params = array_slice($this->uri->rsegment_array(), $param_offset);
// Call the determined method with all params
call_user_func_array(array($this, $method), $params);
}
