I'm having some trouble with a random number that is not random. I am basically generating a unique 20 digit code but when it's written to the db, the same number appears (95% of the time). I'm wondering if this is down to some caching or something?
Controller:-
Code:
public function send($per_id = NULL) {
$securitycode = $this->Enter_detail->gen_string();
$this->load->model('Email');
$this->load->model('Notifications');
$data['type'] = 'Most popular';
if ((!is_numeric($per_id)) or ($per_id < 0)) {$per_id = 0;} //get page number variable from URI and set if not unsigned integer
if ($this->input->post('gift'))
{
$mathcode = strip_tags($this->input->post('code'));
//first check if math captcha is correct
if ($mathcode != $this->session->userdata('realcd'))
{
$error = $this->notificationmssgs->errors();
$this->session->set_flashdata('error', $error[22]);
redirect('home/page');
}
//check if member has sent per_id a message in last 24 hours
if ($this->Enter_detail->check_if_gift_before($this->session->userdata('mem_id'), $per_id))
{
$error = $this->notificationmssgs->errors();
$this->session->set_flashdata('error', $error[20]);
redirect(base_url('home/page/search'));
}
$filtermssg = $this->Messagefilter->filter($this->input->post('message'));
$this->Enter_detail->submit_gift($this->input->post('gift'), $per_id, $filtermssg, $securitycode);
$this->Email->add_notification($per_id, $this->session->userdata('mem_id'), 'has sent you a gift!');
$this->Notifications->add_notification($per_id, $this->session->userdata('mem_id'), 'gift', $securitycode);
$notification = $this->notificationmssgs->notifications();
$this->session->set_flashdata('message', $notification[11]);
redirect('home/page/search');
}
$data['type'] = $this->input->post('type');
//check that member is permitted to message per_id
if ($this->Extract_detail->check_if_banned($per_id)) {
$error = $this->notificationmssgs->errors();
$this->session->set_flashdata('error', $error[14]);
redirect(base_url('home/page/search'));
}
//get username of per_id
$data['username'] = $this->Extract_detail->get_username($per_id);
$data['per_id'] = $per_id;
//choose which gifts to load based on member selection
$data['gifts'] = $this->Extract_detail->gift_selection($data['type']);
$this->load->view('blocks/spacer');
$this->load->view('blocks/notificationbar', $data);
$this->load->view('gift-send', $data);
$data['bottomscript'] = '[removed][removed]';
$this->load->view('blocks/footer', $data);
}//SEND
and the relevant functions are:-
Code:
public function gen_string() {
$this->load->helper('string');
return random_string('numeric', 20);
}//gen_string
public function submit_gift($id, $per_id, $message, $seccode) {
$this->load->helper('date');
$datetime = unix_to_human(time(), TRUE, 'eu');
$data = array(
'id' => $seccode,
'gift_id' => $id,
'mem_id' => $this->session->userdata('mem_id'),
'per_id' => $per_id,
'message' => $message,
'datetime' => $datetime
);
$this->db->insert('network_gifts', $data);
}//submit_gift
Ignoring the fact that there are a few things I will do to optimise the scripts, why is it that when the DB is written, the same value appears for id?
