Can anyone tell me why flashdata is not immediately available? Is it only available once the page has been resent? I am using form validation for form fields and flashdata for error messages. If there is an error I want the fields to be filled in with the $_POST data, which CI does easily, however, the flashdata seems to only be recognised once I refresh (through redirect()) which destroys the $_POST data.
If I remove the redirect then validation errors and automatic re-entering of posted values works, but no flashdata message.

Code:
// Validation rules
$this->form_validation->set_rules('name', 'username', 'required|alpha_dash');
$this->form_validation->set_rules('pass', 'password', 'required|alpha_dash');
// Check form has been submitted with valid form info
if ($this->form_validation->run()) {
$name = $this->input->post('name');
$pass = $this->input->post('pass');
...
// Return if name and password was not found
if ($check===FALSE) {
$this->session->set_flashdata('message_type', 'warning');
$this->session->set_flashdata('message', 'Username not found.');
// Success
} else {
...
$this->session->set_flashdata('message_type', 'information');
$this->session->set_flashdata('message', 'Logged in.');
}
// Success or fail redirect page
redirect('user/login'); exit();
}
// Load Page
$this->load->view('v_user_login');
Code:
<?php if($this->session->flashdata('message')) : ?>
<div class="<?=$this->session->flashdata('message_type')?>">
<h3><span> </span><?=$this->session->flashdata('message')?></h3>
</div>
<?php endif; ?>
