Get Value of a hidden form_input using CodeIgniter - php

Question

I cannot get the hidden value of form if it is hidden.
My form view:
<?php echo form_input(array(
'class'=>'emp_name',
'name'=>'emp_name',
'id'=>'emp_name',
'value'=>'')
);?>
<?php echo form_hidden('emp_id', ''); ?>
I set employee name by using jquery autocomplete and then set the emp_id value to the returned ID with the name.
My Controller:
$data = array(
'emp_id'=>$this->input->post('emp_id')
);
This conroller is the form of my view above. I can get the emp_name properly but not the emp_id because it is hidden, if I do not use hidden it works fine. Any idea how can I hide the ID by getting the value in my conntroler?

Answer 1

It looks like you are not submitting the form to the system.
You need to open/close and submit the form.
Quick little test:
class Test_form extends CI_Controller
{
function __construct()
{
parent::__construct();
//displays the profiler info to make debugging easy
$this->output->enable_profiler(TRUE);
}
function test_form()
{
echo form_open();
echo form_input(array(
'class'=>'emp_name',
'name'=>'emp_name',
'id'=>'emp_name',
'value'=>'')
);
echo form_hidden('emp_id', '');
echo form_submit();
echo form_close();
}
}
