I would like to answer this question as this comes all times up in searches --

You can call a controller method in view, but please note that this is not a good practice in any MVC including codeigniter.

Your controller may be like below class --

<?php
    class VCI_Controller extends CI_Controller {
    ....
    ....
    function abc($id){
       return $id ;
    }

    }
?>

Now You can call this function in view files as below --
<?php
    $CI =& get_instance();
    $CI->abc($id) ;

?>

Codeigniter is an MVC  Model - View - Controller  framework  It s really not a good idea to call a function from the view  The view should be used just for presentation  and all your logic should be happening before you get to the view in the controllers and models   A good start for clarifying the best practice is to follow this tutorial    https   codeigniter com user guide tutorial index html  It s simple  but it really lays out an excellent how-to   I hope this helps

it is quite simple just have the function correctly written in the controller class and use a  tag to specify the controller class and method name  or any other neccessary parameter     lt  php if     defined  BASEPATH    exit  No direct script access allowed    class Iris extends CI Controller       function   construct            parent    construct             this- gt load- gt model  script             this- gt load- gt model  alert          public function pledge ph             this- gt script- gt phpledge              gt    This is the controller class Iris php and the model class with the function pointed to from the controller class    lt  php  if     defined  BASEPATH    exit  No direct script access allowed    class Script extends CI Model       public function   construct             parent    construct               Your own constructor code      public function ghpledge             gh id   uniqid rand 1 11             date date  y-m-d             gh member     SESSION  member id             amount  10000           data   array               gh id   gt   gh id               gh member   gt   gh member               amount   gt   amount               date   gt   date                     this- gt db- gt insert  iris gh   data              gt    On the view instead of a button just use the anchor link with the controller name and method name    lt html gt       lt head gt  lt  head gt       lt body gt           lt a href   lt  php echo base url      gt index php iris pledge ph  class  btn btn-success  gt PLEDGE PH lt  a gt       lt  body gt   lt  html gt

One idea i can give is   Call that function in controller itself and return value to view file  Like   class Business extends CI Controller       public function index                  data  css      profile                 data  cur url      this- gt getCurrURL       the function called and store val              this- gt load- gt view  home view   data               function getCurrURL                      currURL  http       SERVER  HTTP HOST       ltrim   SERVER  REQUEST URI                        return  currURL              in view home view php  use that variable  Like   echo  cur url

I know this is bad   But I have been in hard situation where it is impossible to put this back to controller or model   My solution is to call a function on model  It can be do inside a view  But you have to make sure the model has been loaded to your controller first   Say your model main model  you can call function on the model like this on your view    this- main model- your function     Hope this help

if you need to call a controller from a view  maybe to load a partial view  you thinking as modular programming  and you should implement HMVC structure in lieu of plane MVC  CodeIgniter didnt implement HMVC natively  but you can use this useful library in order to implement HMVC  https   bitbucket org wiredesignz codeigniter-modular-extensions-hmvc  after setup remember that all your controllers should extends from MX Controller in order to using this feature

You can call a controller function with AJAX on your view  In this case  I m using the jQuery library to make the call    lt script type  text javascript  gt        ajax               url    lt   site url  controller function    gt                type   post      To protect sensitive data             data                   ajax true                 variableX   string                  variableY  25                  and any other variables you want to pass via POST                                   success function response                  Handle the response object                            lt  script gt    This way you can create portions of code  modules  and reload them the AJAX method in a HTML container
