Search submit button not working in CodeIgniter - php

Question

I have built a page with CodeIgniter, that has a search function and a datatable.
Whenever I click the search button, the datatable will change accordingly to the parameter submitted. But it not working as I expected.
This is My Model
public function ocsmodel($biostype=null, $manufacture=null)
{
// Loading second db and running query.
if ($biostype==null and $manufacture == Null) {
$this->ocs = $this->load->database('ocsweb', TRUE);
return $this->ocs->select('ocslist.*')
->from('ocslist')
->limit(100)
->get();
}
else {
if ($manufacture == "") {
}
else {
$this->ocs = $this->load->database('ocsweb', TRUE);
return $this->ocs->select('ocslist.*')
->from('ocslist')
->where('bios_type',$biostype)
->where('smanufature',$manufacture)
->limit(100)
->get();
}
}
}
This is my controller
public function ocslist()
{
$manufactur ="";
$biostype ="";
if (isset($_POST['bios_type'])){
$biostype = $this->input->post('bios_type');
if (isset($_POST['manufacture'])){
$manufactur = $this->input->post('manufacture');
}
$data['ocs'] = $this->assetmodel->ocsmodel()->result_array();
}
else {
$data['ocs'] = $this->assetmodel->ocsmodel($biostype,$manufactur)->result_array();
}
$data['ocstype'] = $this->assetmodel->getocstype()->result_array();
$data['ocsmanu'] = $this->assetmodel->getocsmanu()->result_array();
$data['content'] = 'master/ocs_list';
$this->load->view('template', $data, FALSE);
}
And This is My View
<div class="right_col" role="main">
<div class="">
<div class="page-title">

Answer 1

what about changing your controller into something like
public function ocslist()
{
$data['ocs'] = $this->assetmodel->ocsmodel($this->input->post('bios_type'), $this->input->post('manufacture'))->result_array();
$data['ocstype'] = $this->assetmodel->getocstype()->result_array();
$data['ocsmanu'] = $this->assetmodel->getocsmanu()->result_array();
$data['content'] = 'master/ocs_list';
$this->load->view('template', $data, FALSE);
}
because CI sets all POST Data to null if they doesn't exist
For more information look here
Update (20.07.2016)
according to your view try to change the button type into something like this
<button type="submit" class="btn btn-info" name="submit">Search</button>
