I am trying to pass some Data using a link from the view to the Controller.
Controller:
public function details(){
echo $this->input->post('data_id');
$data['details'] = $this->wapi_db->details($this->input->post('data_id'));
$data['latest_news'] = $this->wapi_db->latest_news();
$data['main_content'] = "category/details";
$this->load->view('includes/template',$data);
}
View:
<a href=<?php.base_url().'wapi/details?data_id='6'; ?>
You could simply us Uri segmen, just like this:
your View Code for href.
<a href="<?php echo base_url() ?>wapi/details/6";
And to GET the value you passed from view to controller
You should do something like this in your controller
public function details(){
$data_id = $this->uri->segment(3); //this where you get you value from your link
...//rest of your code
}
I recommend you to use this link on your view
<a href=<?php.base_url().'wapi/details/6'; ?>
Then on your controller you just wait for the parameter on the function
public function details($data_id){//<- the parameter you want
$data['details'] = $this->wapi_db->details($data_id);
$data['latest_news'] = $this->wapi_db->latest_news();
$data['main_content'] = "category/details";
$this->load->view('includes/template',$data);
}
If your URI contains more than two segments they will be passed to your method as parameters.
From Codeigniter Controllers Guide
You need to use
$this->input->get('data_id')
because you're passing data via GET method.
So your code should be:
public function details(){
echo $this->input->get('data_id');
$data['details'] = $this->wapi_db->details($this->input->get('data_id'));
$data['latest_news'] = $this->wapi_db->latest_news();
$data['main_content'] = "category/details";
$this->load->view('includes/template',$data);
}

I can't pass the data from the controller to the view in CodeIgniter 3. All the thing seem okay. Do I need to put the Controller's part in the index() method?
Donor_Model.php
function viewDonors() {
$query = $this->db->get('donors');
return $query;
}
Staff.php controller
public function viewDonors()
{
$this->load->Model('Donor_Model');
$data['donors'] = $this->Donor_Model->viewDonors();
$this->load->view('viewdonors', $data);
}
When I try to call the $data in the viewdonors.php view, it shows the $donors as undefined.
screenshot of viewdonors.php
#TimBrownlaw is right. Even though the IDE shows an error, the code runs without a problem.
You need to edit your model page to:-
function viewDonors() {
$query = $this->db->get('donors');
return $query->result();
}
As you want to loop through donors data in the view page so you need to return result function in the model.
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
<html>
<?php echo $data; ?>
</html>
$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>
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;
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.
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.
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
you can do it this way
defined array in controller
$data['hello'] = "hello";
and pass variable to view
echo $hello;
If you pass
$data = your code
$this->load->view('your-page', $data);
and get data on your view as
<?php echo $data;?>
It won't work because ci didn't understand this patern. If like to pass value form controller to view so you can try this -
controller -
$data['any-name'] = your values;
$this->load->view('your-page', $data);
then in your view you can get this data by -
<?php echo $any-name;?>
Hope this helps you.
In your controller you can pass
$data['poll'] = "Your results";
In your view you can call
echo $poll;
In controller:
$data["result"] = $this->login_model->get_login(); // Get array value from DB..
$this->load->view('login-form',$data); // Pass the array to view
In view:
print_r($result); // print the array in view file
Ok so I finally solved it. You should really have a model (it helps a lot)
In your model do something like
Model
class poll_model extends CI_MODEL {
function __construct() {
$this-load->database();
}
function get_poll {
$this->db->query("SELECT * FROM table");
$row = $query->row();
$obj = array(
'id' => $row->id
);
return $obj;
}
}
Now if you have more than an id say name of poll # you can add in array.
Now in your controller do
class Poll extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->database();
$this->load->helper('form');
$this->load->model('poll_model');
}
public function index()
{
$data["a"] = $this->poll_model->get_poll();
$this->load->view('poll_view',$data);
}
And finally in VIEW put
<? echo $a["id"]; ?>
This is a big help. I figured it out by testing and it works for me.
I have seen all above answer so here is what I do when I have to load the data from the controller to my view.
To Pass the Data To the view from the controller:
public function your_controller(){
// Your Necessary Code
// You have the $data, $data2, $data3 to post to the view.
$this->load->view('your_view_directory or view_page',['data'=>$data, 'data2'=>$data2, 'data3'=>$data3... so on ]);
}
And At the View Side You can simply retrieve that data:
To Display You can simply use echo, print, print_r. And if you want to loop over it, you can do that as well.
In controller:
public function product(){
$data = array("title" => "Books", "status"=>"Read","author":"arshad","company":"3esofttech",
"subject":"computer science");
Data From Model to controller
$this->load->model('bookModel');
$result = $this->bookModel->getMoreDetailsOfBook();
**Add *$result* from model to *$data* array**
$data['tableRows'] = $result;
$data from Controller to View
$this->load->view('admin/head',$data);
And to access in view file
views/user.php
<?php echo $data;
foreach($tableRows as $row){ echo
$row['startData']; } ?>
Instead of
$data = "hello";
$this->load->view('results_view', $data);
Do
$data['hello'] = 'hello';
$this->load->view('results_view', $data);
In your controller file and controller will send data having hello as string to results_view and in your view file you can simply access by
echo $hello;
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');

}
public function vote()

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

I want something like this but it wont work, that means I am doing it wrong.
$route['print/:num'] = "user/doprint/goprint/:num";
Let me explain. I have a controller doprint under user folder and the goprint is a method inside doprint which accepts a id as argument. Now i dont want the users to visit it by mydomain.com/user/doprint/goprint/2. I want them to visit it as mydomain.com/print/2.
my controller is as below
class Doprint extends User_Controller {
public function index()
{
$data['subview'] = 'print';
$this->load->view('main_layout', $data);
}
public function goprint($id=NULL)
{
$data['model'] = $this->usermodel_model->get($id);
$data['subview'] = 'print';
$this->load->view('main_layout', $data);
}
}
The route rule syntax is (per the documentation):
$route['print/(:num)'] = "user/doprint/goprint/$1";
I'm trying to create user profiles for my site where the URL is something like
mysite.com/user/ChrisSalij
Currently my controller looks like so:
<?php
class User extends Controller {
function user(){
parent::Controller();
}
function index(){
$data['username'] = $this->uri->segment(2);
if($data['username'] == FALSE) {
/*load default profile page*/
} else {
/*access the database and get info for $data['username']*/
/*Load profile page with said info*/
}//End of Else
}//End of function
}//End of Class
?>
At the moment I'm getting a 404 error whenever i go to;
mysite.com/user/ChrisSalij
I think this is because it is expecting there to be a method called ChrisSalij.
Though I'm sure I'm misusing the $this->uri->segment(); command too
Any help would be appreciated.
Thanks
It's because the controller is looking for a function called ChrisSalij.
A few ways to solve this:
change
function index(){
$data['username'] = $this->uri->segment(2);
to be
function index($username){
$data['username'] = $username;
and use the URL of mysite.com/user/index/ChrisSalij
if you don't like the idea of the index being in the URL you could change the function to be called a profile or the like, or look into using routing
and use something along the lines of
$route['user/(:any)'] = "user/index/$1";
to correctly map the URL of mysite.com/user/ChrisSalij
