session flashdata read write probleme ...

#1
hallow guys. hope you doing good

so my problem is I want to throw toaster message telling users status of last operation like:


Code:
$this->session->set_flashdata('error_message',get_phrase('invalid_login_credentials'));


then i redirect to home page and catch the messages : 


Code:
redirect(site_url('home'), 'refresh');


Code:
<?php if ($this->session->flashdata('error_message') != ""):?>

<script type="text/javascript">

    $(document).ready(function () {
        toastr.error('<?php echo $this->session->flashdata("error_message");?>');

    });
</script>

<?php endif;?>


every thing work fine in xampp localhost. but in live server sometimes the message show sometimes not. after testing and debugging i found that $this->session->flashdata("error_message") is empty when message not show. and i try to use userdata rather flashdata i found that sometimes in first redirect message not shown ( same thing as flashdata ) but in every other refresh message shown in userdata.

is that because session blocking or CodeIgniter problem or maybe slow writing mechanism ?

here my session configuration

Code:
$config['sess_driver'] = 'database';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 259200;
$config['sess_save_path'] = 'ci_sessions';
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 0;
$config['sess_regenerate_destroy'] = FALSE;


pls help me in this.
thanks

Did you try.

PHP Code:
$session->keepFlashdata(['item1''item2''item3']); 

To see if it needs an extra save call.

Your calling JavaScript then your calling toaster which is JavaScript so the flash data
is mostly being destroyed.

when i run tests on the problem i fount that in this line 
Code:
<?php if ($this->session->flashdata('error_message') != ""):?>
 
flashdata('error_message') is empty which is before i call JavaScript.

i think it is slow write read mechanisme because like said it work somtimes and when i use userdata instead of flashdata in first redirect sometimes show somtimes not (empty) like flashdata but after that after each refresh it always show 
how you explain this ?
i try to use sleep before check the session to delay excution but it not work
