在 CodeIgniter 4 Flashdata 显示代码再次重定向到同一页面中

Question

In the CodeIgniter 4, I am using Flashdata for displaying error or success messages in view page and I am using the below code:

<?php
    if(session()->get("success")){
        echo session()->get("success");
    }
?>

It is not and as well as it redirect frequent in same page using this code!

Answer 1

use Flashdata instead of session .

Once you reload the page, flashdata will disappear

$session->setFlashdata('item', 'value');
# to rerive
$session->getFlashdata('item');

You can warp it with if conditions well.

if($session->getFlashdata('item')){}
