//question 1
//for set the session
$_SESSION[‘feedback’] = ‘Feedback send successfully’;

//for viewing as well as checking the session and unset the session

<?php
        if(isset($_SESSION[‘feedback’]))
        {
echo $_SESSION['feedback'];
unset($_SESSION['feedback']);
}
?>

//if i use accordingly ur suggestion
$this->session->set_flashdata(‘feedback’, ‘Message’);

//then what to do for viewing as well as checking the session and unset the session:
//my wild guess is:
  if(isset($this->session->set_flashdata(‘feedback’)))
        {
echo $this->session->set_flashdata(‘feedback’);
          unset($this->session->set_flashdata(‘feedback’));
        }
//will it work? please describe with code as i am new to CI

//question 2
//can i set more index and value in set_flashdata like
$this->session->set_flashdata(‘feedback’=>‘Message’, ‘comments’=>‘thanks for ur feedback’);

Firstly, this doesn’t belong in the lounger, as it’s actually code stuff 😉
Secondly, a good place to answer your questions is the user guide, have you read it?
Thirdly, Use [ code ] blocks in future!

And finallly on to your questions
With flashdata, and session data in general, you don’t need to check if it’s set, as if you call a key which doesn’t exist, it will return false
And with flashdata, the whole point of it is you don’t need to worry about unsetting it, as it will expire after one page

And as for the second Q, you can either call set_flashdata multiple times passing the key/value pairs, or pass it an array (it’s all covered in the user guide)

In pretty much all of your posts I’ve seen, you have a piece of code in there, but it’s as plain text, like so
<?php
      if(isset($_SESSION[‘feedback’]))
      {
echo $_SESSION[‘feedback’];
unset($_SESSION[‘feedback’]);
}
?>

where as really, you should wrap that text in [code]code goes here[/code] blocks, so it will display like

<?php
        if(isset($_SESSION[‘feedback’])) 
        {
          echo $_SESSION[‘feedback’];
          unset($_SESSION[‘feedback’]);
        }
?>

Much more readable for every one trying to help you, wouldn’t you say?
And if you’re using the full reply editor (instead of quick reply) there’s even a ‘code’ button that does the tags for you
