Question

I can't passing the variables in view page
this is my controller code
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Management extends CI_Controller {
public function __construct()
{
parent::__construct();
if($this->session->userdata('level') != 1){
redirect('');
}
}
public function hotels()
{
$this->load->model('model_hotels');
$ss['most_view_hotels'] = '23';
$this->load->view("management/header_mng_view");
$this->load->view('management/hotels_mng_view' , $ss , true);
$this->load->view("management/footer_mng_view");
}
}
this is the error
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: most_view_hotels
Filename: management/hotels_mng_view.php
Line Number: 22
hotels_mng_view.php
<?php
echo $most_view_hotels;
foreach($most_view_hotels as $value):
?>
<div class="row">
<div class="cell en">adsf</div>
<div class="cell en">1212</div>
<div class="cell en">12</div>
<div class="cell en">32</div>
</div>
<?php endforeach;?>

Answer 1

In your controller:
$ss['most_view_hotels'] = '23';
$this->load->view("management/header_mng_view");
$this->load->view('management/hotels_mng_view',$ss);
$this->load->view("management/footer_mng_view");
In your view:
<?php echo $most_view_hotels?>

Answer 2

In you're template you would refer to the item as...
$most_view_hotels
So we need to verify this is what you are doing in the view management/hotels_mng_view.php

Answer 3

As said on Codeigniter manual:
There is a third optional parameter lets you change the behavior of the function
so that it returns data as a string rather than sending it to your browser.
This can be useful if you want to process the data in some way. If you set
the parameter to true (boolean) it will return data.
The default behavior is false, which sends it to your browser.
What this means is that your line
$this->load->view('management/hotels_mng_view' , $ss , true);
actually returns result of that view as string to php instead of sending it to browser.
The answer to your actual question ( undefined variable ), relies in in management/hotels_mng_view.php, possibly a typo.

Answer 4

I think the problem is with third parameter, ie true.
As codeigniter documentation says:
There is a third optional parameter lets .....
Remember to assign it to a variable if you want the data returned
And in your code you are not assigning, returned data to any code.
I suggest you to try something like this:
public function hotels()
{
$this->load->model('model_hotels');
$data = array();
$ss['most_view_hotels'] = '23';
$data['header'] = $this->load->view("management/header_mng_view",,true);
$data['body'] = $this->load->view('management/hotels_mng_view' , $ss , true);
$data['footer'] = $this->load->view("management/footer_mng_view");
$this->load->view("template",$data);
}
/*template view file*/
<?php
echo $header;
echo $body;
echo $footer;
?>
Hope this helps.
