How to call controller function from view in codeigniter?

Question

With codeigniter, I have a controller as in the following:

Answer 1

if You Want to call controller function like this /CodeIgniter/myController/myFn then, You have to remove index.php file using .htaccess file. First You change config.php file like this.

//  Remove index.php

$config['index_page'] = ""

then, create .htaccess file and copy this code to that file.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

Then, put this .htaccess file inside codeignator project folder.

In your controller just delete ' ** '.

<?php if(!defined ('BASEPATH')) exit('not found basepath');

class myController extends CI_Controller{

    function __constructor(){
        parent::__constructor();
    }

    public function index(){
        $this->load->view('myview');
    }

    public function myFn(){
    echo "my controller is called"; 
    }
}
?>

And In your view try:

<?php echo form_open('myController/myFn'); ?>
<?php echo form_submit('submit','SUBMIT'); ?>

Answer 3

when you run the view

<form action="<?php echo base_url();?>myController/myFn" method="post" name="myform">
<input type="submit" name="submit" value="submit"/>
</form>

use inspect element to see if the action in the form tag is same as

**http://localhost/CodeIgniter/index.php/myController/myFn**

I think you forgot to load URL helper

function test()
{

    $this->load->helper('url');
    $data['message']= $this->input->post('message');
    $this->load->view('backend/test',$data);

}

this might help you
