So I have this IF statement in my view. it works and all, but wondering if there’s a better way to write this. Having both session calls seem unneccessary…

if($this->session->userdata('campaign_name')){
    echo $this->session->userdata('campaign_name');
}
else {
    echo 'this';
}

Note this function will be used inline on a text input. So I’m looking for as minimal code as possible.

    Note that CI’s Session class’s userdata method will return false if no campaign_name exists. So assign a variable to the potentially undefined array key (campaign_name)

    $campaign_name = $this->session->userdata('campaign_name');

if($campaign_name)
{
    echo $campaign_name;
}
else
{
    echo 'this';
}

    OR

    if($campaign_name = $this->session->userdata('campaign_name'))
{ 
   echo $campaign_name;
}

    Controller Method (/application/controllers/test_controller.php)

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

    class Test_Controller extends CI_Controller
    {
        function __construct()
        {
            parent::__construct();

        }
        public function myFunction()
        {
            $data['campaign_name'] = $this->session->userdata('campaign_name');
            $this->load->view('test_view',$data);

        }
    }

    View (/application/view/test_view.php)

    <html>
<head></head>
<body>
     <input type="text" value="<?php echo $campaign_name; ?>">
</body>
</html>
