php codeigniter view controller

Solution 1

$data should be an array or an object: http://codeigniter.com/user_guide/general/views.html

$data = array(
    'title' => 'My Title',
    'heading' => 'My Heading',
    'message' => 'My Message'
);

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

results_view.php

<html>
<?php 
//Access them like so
echo $title.$heading.$message; ?>
</html>

Solution 2

In simple terms,

$data['a'] in controller becomes $a in your view. ($data won't exist in your view, only the index will become available)

e.g.

Controller:    
$data['hello']='hellow world';

view:
echo $hello;

Solution 3

You just need to create a array, you using codeigniter right?

Example on controller:

$data['hello'] = "Hello, world";
$this->load->view('results_view', $data);

In de page "results_view" you just have to:

<?php echo $hello;?>

Obs: You can create n datas, just pay attention in the name and make it a array.

Obs²: To use the data use the key of the array with a echo.

Solution 4

The view wouldn't call the data 'data'

The controller would include an associative index (not sure if that's correct nomenclature) for data e.g 'stuff' looking thus $data['stuff']

You'd echo in the view so: echo $stuff; not echo $data;

I am a v lowly code fiddler but do really like CodeIgniter so excuse me if i've got this arse about tit.

One more thing - surely your constructor function is a bit of a waste. All that loading of libraries and helpers is done with the autoload file.

Solution 5

You can create property $data = []; inside CI_Controller(path: system/core/Controller.php) and store all data to show in view. U can load common data like languages, menu, etc in CI_Controller. Also u can add special data for view in controller. (example: $this->data['message'] = "Hello world";) Finally, u can pass $this->data to view when load view (example: $this->load->view('view_name',$this->data);)

I hope this will help you

I want to pass $data from the controller named poll to the results_view however I am getting an undefined variable error.

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Poll extends CI_Controller {

    public function __construct()
       {
            parent::__construct();
            $this->load->database();
            $this->load->helper('form');
       }

    public function index()
    {

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

    public function vote()
    {
        echo "Voting Successfull";
        $this->db->insert('votes',$_POST);
    }

    public function results()
    {
        echo "These are the results";
        //$query = $this->db->get('votes');
        $data = "hello";
        $this->load->view('results_view', $data);

    }
}

Results_view.php
