How to load a controller from another controller in codeigniter

Question

I want to load a controller from a function in another controller because the library I integrated to my project I don t want to load it to the controller because I want to keep it clean and related   I tried using modules but I still had to put controller in the url like   http   example com maincontroller function http   example com othercontroller function  I have default controller so I can load http   example com function so how could I access the controller from a function from main so I don t have to put the controller in the url   I m still willing to use HMVC if I can load the controller function from the main controller function

I had a similar problem  I wanted to have two controllers   homepage php - public facing homepage  home php - home screen once a user was logged in  and I wanted them both to read from  mydomain com   I was able to accomplish this by setting  hompepage  as the default controller in my routes config and adding a remap function to homepage php  function  remap       if user is logged in            require once APPPATH  controllers home php          oHome    new Home         oHome- gt index          else          this- gt index

You can t load a controller from a controller in CI - unless you use HMVC or something    You should think about your architecture a bit  If you need to call a controller method from another controller  then you should probably abstract that code out to a helper or library and call it from both controllers   UPDATE  After reading your question again  I realize that your end goal is not necessarily HMVC  but URI manipulation  Correct me if I m wrong  but it seems like you re trying to accomplish URLs with the first section being the method name and leave out the controller name altogether   If this is the case  you d get a cleaner solution by getting creative with your routes    For a really basic example  say you have two controllers  controller1 and controller2   Controller1 has a method method 1 - and controller2 has a method method 2   You can set up routes like this    route  method 1      controller1 method 1    route  method 2      controller2 method 2     Then  you can call method 1 with a URL like http   site com method 1 and method 2 with http   site com method 2   Albeit  this is a hard-coded  very basic  example - but it could get you to where you need to be if all you need to do is remove the controller from the URL     You could also go with remapping your controllers   From the docs   If your controller contains a function named  remap    it will always get called regardless of what your URI contains     public function  remap  method        if   method     some method                  this- gt  method              else                this- gt default method

There are many ways by which you can access one controller into another   class Test1 extends CI controller       function testfunction            return 1            Then create another class  and include first Class in it  and extend it with your class   include  Test1 php    class Test extends Test1       function myfunction             this- gt test            echo 1

Create a helper using the code I created belows and name it controller helper php   Autoload your helper in the autoload php file under config   From your method call controller  name   to load the controller    Note that name is the filename of the controller   This method will append   controller  to your controller  name   To call a method in the controller just run  this- gt name controller- gt method    after you load the controller as described above    lt  php  if  function exists  controller          function controller  name                 filename   realpath   dir          controllers    name   php             if file exists  filename                         require once  filename                class   ucfirst  name                if class exists  class                                  ci   amp  get instance                     if  isset  ci- gt   name   controller                                            ci- gt   name   controller     new  class                                                        gt

While the methods above might work  here is a very good method   Extend the core controller with a MY controller  then extend this MY controller for all your other controllers   For example  you could have   class MY Controller extends CI Controller       public function is logged                   Your code here       public function logout                   Your code here           Then your other controllers could then extend this as follows   class Another Controller extends MY Controller       public function show home                  if    this- gt is logged                 return false                   public function logout                  this- gt logout

I came here because I needed to create a    render      function in Twig  to simulate Symfony2 s behaviour  Rendering controllers from view is really cool to display independant widgets or ajax-reloadable stuffs   Even if you re not a Twig user  you can still take this helper and use it as you want in your views to render a controller  using  lt  php echo twig render  welcome index    param1   param2         gt   This will echo everything your controller outputted   Here it is   helpers twig helper php   lt  php  if   function exists  twig render           function twig render                  args   func get args             route   array shift  args            controller   APPPATH    controllers     substr  route  0  strrpos  route                   explode   explode       route           if  count  explode   lt  2                        show error  twig render  A twig route is made from format  path to controller action                        if   is file  controller     php                          show error  twig render  Controller not found    controller                       if   is readable  controller     php                          show error  twig render  Controller not readable    controller                       require once  controller     php              class   ucfirst reset array slice  explode  count  explode  - 2  1             if   class exists  class                         show error  twig render  Controller file exists  but class not found inside    class                         object   new  class            if     object instanceof CI Controller                         show error  twig render  Class   class  is not an instance of CI Controller                        method    explode count  explode  - 1           if   method exists  object   method                         show error  twig render  Controller method not found    method                        if   is callable array  object   method                          show error  twig render  Controller method not visible    method                        call user func array array  object   method    args             ci    amp get instance            return  ci- gt output- gt get output               Specific for Twig users  adapt this code to your Twig implementation    libraries Twig php   this- gt  twig env- gt addFunction  render   new Twig Function Function  twig render       Usage     render  welcome index   param1  param2

you cannot call a controller method from another controller directly   my solution is to use inheritances and extend your controller from the library controller   class Controller1 extends CI Controller        public function index                some codes here            public function methodA               code here           in your controller we call it Mycontoller it will extends Controller1  include once  dirname   FILE        controller1 php     class Mycontroller extends Controller1        public function   construct             parent    construct               public function methodB               codes               and you can call methodA from mycontroller  http   example com mycontroller methodA  http   example com mycontroller methodB  this solution worked for me
