对Codeigniter中的“添加”和“编辑”使用相同的功能？

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);
}
