Codeigniter after insert success message show in view - codeigniter

Question

I am new in Codeigniter and I need to show success and error message after insert data's in database.
How can I show the message in the view page?
This is my coding:
Model
function addnewproducts($data)
{
if($data['product_name']!="" && $data['product_qty']!="" && $data['product_price']!="" && $data['date']!="")
{
$res=$this->db->insert('product_list',$data);
return $this->db->insert_id();
}
else
{
return false;
}
}
Controller
function addnewproduct()
{
$this->load->model('products');
$data['product_name'] = trim(strip_tags(addslashes($this->input->post('product_name'))));
$data['product_qty'] = trim(strip_tags(addslashes($this->input->post('product_qty'))));
$data['product_price'] = trim(strip_tags(addslashes($this->input->post('product_price'))));
$data['datetime']=date('d-m-Y');
$res = $this->products->addnewproducts($data);
if($res==true)
{
$data['success'] = 'Successful';
$this->load->view('addproduct',$data);
}
}
View
<p><?php echo $success; ?></p>

Answer 1

There are many ways but below is which i recommend:
Set temp session in controller on success or error:
$res = $this->products->addnewproducts($data);
if($res==true)
{
$this->session->set_flashdata('success', "SUCCESS_MESSAGE_HERE");
}else{
$this->session->set_flashdata('error', "ERROR_MESSAGE_HERE");
}
In View you can display flashdata as below:
echo $this->session->flashdata('success');
or
echo $this->session->flashdata('error');

I appreciate that you got your answer but I think flash data is bit old now, as we can use bootstrap to alert if any error and that looks good to on web page.
In controller
$res = $this->products->addnewproducts($data);
if($res==true)
{
$this->session->set_flashdata('true', 'write_the_message_you_want');
}
else
{
$this->session->set_flashdata('err', "write_the_message_you_want");
}
In View
<?php
if($this->session->flashdata('true')){
?>
<div class="alert alert-success">
<?php echo $this->session->flashdata('true'); ?>
<?php
} else if($this->session->flashdata('err')){
?>
<div class = "alert alert-success">
<?php echo $this->session->flashdata('err'); ?>
</div>
<?php } ?>

Controller:
function addnewproduct()
{
$this->load->model('products');
$data['product_name'] = trim(strip_tags(addslashes($this->input->post('product_name'))));
$data['product_qty'] = trim(strip_tags(addslashes($this->input->post('product_qty'))));
$data['product_price'] = trim(strip_tags(addslashes($this->input->post('product_price'))));
$data['datetime']=date('d-m-Y');
if($this->products->addnewproducts($data));
{
$this->session->set_flashdata('Successfully','Product is Successfully Inserted');
}
else
{
$this->session->set_flashdata('Successfully','Failed To
inserted Product');
}
// redirect page were u want to show this massage.
redirect('Controller/Fucntion_name','refresh');
}// close function
view :
On Redirect Page write This code top of Form
<?php if($responce = $this->session->flashdata('Successfully')): ?>
<div class="box-header">
<div class="col-lg-6">
<div class="alert alert-success"><?php echo $responce;?></div>
</div>
</div>
<?php endif;?>
