Question

i have 2 page, which contains delete some record, check out the first controller to delete

function delete($idnya)
{
            $this->m_kategorimaterial->delete($idnya);
            $this->session->set_flashdata('sukses','Hapus kategori material berhasil');
            redirect('c_kategorimaterial');
}

then loaded on view

<div id="vkategorimaterial">
            <p><h2>Menu Kategori Material</h2></p>
        <center><notif><?php echo $this ->session->flashdata('sukses'); ?></notif></center>

and it works like i need. but then its not working on the other controller

function delete($idnya)
{
    $this->m_material->delete($idnya);
    $this->session->set_flashdata('sukses','Hapus material berhasil');
    redirect('c_material');
}

and here is the views of material

<div id="vmaterial">
            <p><h2>Menu Material</h2></p>
    <center><notif><?php echo $this->session->flashdata('sukses'); ?></notif></center>

why does the flashdata is not showing on material page ? but it works on kategorimaterial page ? FYI, first, i make the

                $this->session->set_flashdata('sukses','Hapus kategori material berhasil');

on the kategorimaterial page, once it works, i copy the

                $this->session->set_flashdata('sukses','Hapus kategori material berhasil');

into material controller then change the value. and its not working. how do i resolve this ?

<notif> tag needed due to css styling make green color on every flashdata message

Answer 1

I may advice you to try to track session variable by adding in the view

var_dump($this->session);

You don’t seem to be something wrong but you may try to add this in the controller of material page

function index()
{
    $sukses=$this->session->flashdata('sukses');
    if(isset($sukses)
       $data['sukses']=$sukses;
//load your view 
}

and in your view of course

<div id="vmaterial">
            <p><h2>Menu Material</h2></p>
    <center><notif><?php echo $sukses; ?></notif></center>

It’s strange issue for sure but you may give this a try and waiting for your feedback
