Question

I’m struggling with Flash Data in CodeIgniter.

I basically want to:

add a category to a database
redirect user back to a page
show a success pop-up message “Your category has been created”

So far I can add the category successfully to the db and the user input is validated correctly, only thing is I don’t know how to create the pop up success message. (I don’t want to load a success view), just redirect back to where they came from and show small message in the top corner or something.

Is flash data the right way to go?

Answer 1

In your controller:

//add to db
// load session library if not auto-loaded
$this->session->set_flashdata('msg', 'Category added');
redirect('controller/method');

In the view:

<script>
// assumes you're using jQuery
$(document).ready(function() {
$('.confirm-div').hide();
<?php if($this->session->flashdata('msg')){ ?>
$('.confirm-div').html('<?php echo $this->session->flashdata('msg'); ?>').show();
<?php } ?>
});
</script>
