Codes:
View
<html>
<body>
<?php echo form_open('samplecontroller/sample'); ?>
<input type="text" name="samplename"/>
<input type="submit" value="go"/>
<?php echo form_close(); ?>
</body>
</html>
Controller
<?php
Class samplecontroller extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('Sample_insert');
}
function index()
{
$this->load->view('sample.php');
}
function show($data)
{
$this->load->view('sampleresult',$data);
}
function sample()
{
if($result = $this->Sample_insert->insert_into_sample())
{
$this->show($result);
}
}
}
?>
Model
<?php
Class Sample_insert extends CI_Model
{
function insert_into_sample()
{
$sample = array(
'samplename' => $this->input->post('samplename'),
);
$this->db->insert('sample', $sample);
$latest_id = $this->db->insert_id();
return $latest_id;
}
}
?>
The flow is that, i have 2 views. The other one contains only 1 text input, after which goes to controller then controller passes it on to model then model gets the value within the text input then inserts to my sample table.
The sample table has 2 columns, id(PK,AI) and name
after it inserts, on my model. i added a line, return $latest_id. Then passes goes back to my controller then passes it off to another view that only has
print_r($data);
After all that, it displays an error.
Message: Undefined variable: data
Im not sure where the flow went wrong or if i made a syntax mistake. If someone knows/expert on insert_id(), could you pin point where exactly i am wrong? anyways, ive made my research and been getting results on the web how buggy insert_id is. Im not sure if its true or not but ive been redirected mostly to forums wherein insert_id returns null and some say its a bug. Im hoping it isnt.
