CodeIgniter - How to set array flashdata and call the message?

Question

I have a CodeIgniter web apps using foreach for user insert data then if the submitted data is successfully inserted, I created a flashdata message called sc_msg[]. But I have no idea how to call it on flashdata.

$user = $this->input->post('user', TRUE);
foreach ($user as $u)
{
   $this->model->insert($u);
   $sc_msg[] = '- User '.$u.'has been successfully registered<br>';
}

This is a code how I called it on my view.

<?php if ($this->session->flashdata('warning'))
        echo $this->session->flashdata('message'); ?>

I wanted the message called like this :

User abc has been successfully registered

User bca has been successfully registered

User qwe has been successfully registered

User ewq has been successfully registered

All sc_msg[] stored on message so I don't need to using FOR or FOREACH in the views to called it.

The problems is on my controller, I'm trying to set the message :

$this->session->set_flashdata('message', $sc_msg);

It's just print array, so I try to change $sc_msg into $sc_msg[] the result is error : Cannot use [] for reading.

I'm also trying to use foreach inside set_flashdata too and is failed. Unexpected foreach.

Then I'm trying to set the flashdata like this :

 $this->session->set_flashdata('message', $sc_msg[0].$sc_msg[1]);

That is printed the result but only index 0 and index 1. Result :

User abc has been successfully registered

User bca has been successfully registered

There is another 2 messages not called for user qwe and ewq.

I have no idea how to call the message inside the flashdata. But, please don't give me for loop solutions. Thank you.

I seen an easy way to do that Zinc.

Your message on sc_msg[] is already using <br> for next line. Okay, so what you need to do is not using foreach inside the flashdata. But using foreach to append the string from the message.

foreach ($sc_msg as $sm)
{
    $msg = $msg.$sm; // OR using $msg .= $sm;
}

$this->session->set_flashdata('message', $msg);

You can try it, If you have another way to append the string it's good. I just give an simple example for you.
