what should i write to redirect the page from Controller in CI?

问题

here is my Controller

<?php 
class First_Controller extends CI_Controller{
    public function index(){

        $this->load->view('firstpage');
    }

    public function validate_credentials()
    {
        $data[] =array(

            $username=$this->input->post('username'),
            $password=$this->input->post('password')
            );
        $this->load->model('First_Model');
        $result=$this->First_Model->validate($data);

        if($result==true)
        {
            //redirect('welcome');//Error Page is not found
            echo "found";
        }
        else{

            echo "not found";
        }
    }

}
?>

and here is the second controller 



   <?php 
    class Welcome_Controller extends CI_Controller{
        public function index(){

            $this->load->model('First_Model');
            $data['results']=$this->First_Model->display();

            $this->load->view('welcome',$data);

    ?>

Follow These Steps:

Did you load url helper ?

if not then first load the url helper

$this->load->helper('url');

in your function or constructer.

if you want to use it in whole application then load it in autoload.php file
In your config.php file give your site url

$config['base_url']='your site url';
in redirect function give axact path of file name use url helper function

redirect(base_url().'welcome');

if you want to redirect on another controller's function pass it like

redirect('Welcome_Controller');

if the function is index no need to define it, to redirect on another function

redirect('Welcome_controller/anotherFunction');

回答2:

Try this redirect(base_url() . 'index.php/welcome'); if you use htaccess and do not need index.php then make it like redirect(base_url() . 'welcome');

回答3:

redirect('Welcome_Controller');

Thats enough. please check weather your controller name is'Welcome_Controller'

回答4:

For example:

redirect(base_url('cms/lists')); 

//for edit or updating the form - you can pass ID like this

$ID=$this->uri->segment(3);
redirect(base_url("cms/edit/".$ID));
