Flashdata In Codeigniter

In this article, we will discuss flashdata in codeigniter.

Purpose

Flash data is used to store data which is available only in the next request.

Example

In this example, we have following controls

Textbox
Submit button

In controller, write the following code

$this->load->library("session");
if($this->input->post("username"))
{
    if($this->input->post("username") == "gyansangrah")
    {
        $this->session->mark_as_flash('text');
        $this->session->set_flashdata("text", $this->input->post("username"));
    }
    echo $_SESSION['text'];
}

Here, we are setting the flashdata only when user enters the text "gyansangrah" in the textbox.

Output

Here, if we keep on entering the text "gyansangrah", the code will keep on setting flashdata.

There is another scenario.

Picture showing another scenario where page will set flashdata only when word 'Gyansangrah' is entered into the textbox
