CodeIgniter Flash Data
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 $this->session->flashdata('msg'); ?>').show();<?php } ?>});</script>
Your can perform different session message depends what you pass to view from your controller. Noted that I am using Bootstrap as my CSS backbone.
In view,
For success case,
<?php if ($this->session->flashdata('category_success')) { ?> <div class="alert alert-success"> <?= $this->session->flashdata('category_success') ?> </div> <?php } ?>
For error case,
<?php if ($this->session->flashdata('category_error')) { ?> <div class="alert alert-danger"> <?= $this->session->flashdata('category_error') ?> </div><?php } ?>
In controller,
For success case,
$this->session->set_flashdata('category_success', 'Success message.');redirect("To your view");
For error case,
$this->session->set_flashdata('category_error', 'Error message.');redirect("To your view");
