Load dynamic js and css in output view of grocery crud add/edit form

Below is my controller code:

class user extends CI_Controller {

public function __construct() {

parent::__construct ();

$this->load->database ();

$this->load->helper ( 'url' );

$this->load->library ( 'grocery_CRUD' );

}

// View rendering function.

public function _example_output($output = null, $usertype = null) {

$this->load->view ( 'header', $output );

$this->load->view ( 'mainview', $output );

$this->load->view ( 'footer' );

}

// Main function, which displays list.

public function listuser() {

$user_type = $this->session->userdata ( 'usertype' );

try {

$crud = new grocery_CRUD ();

$crud->set_theme ( 'datatables' );

$crud->set_table ( 'user' );

$crud->set_subject ( 'Supplier' );

$crud->columns ( 'name', 'email', 'contact', 'location' );

$crud->where ( 'user_type', 'supplier' );

$crud->order_by ( "user_id", "desc" );

$crud->edit_fields ( 'group_id', 'name', 'email', 'contact', 'location', 'status' );

$crud->add_fields ( 'username', 'password', 'supplier_number', 'group_id', 'name', 'email', 'contact', 'location', 'user_type', 'status' );

$crud->required_fields ( 'group_id','name', 'email', 'contact', 'location', 'status' );

$crud->callback_add_field ( "supplier_number", array (

$this,

"add_supplier_number"

) );

$this->load->model ( "user_group" );

$group = $this->user_group->get_user_group ();

foreach ( $group as $key => $value ) {

$group_dropdown [$value ['group_id']] = $value ['group_name'];

}

$crud->field_type("group_id", "dropdown",$group_dropdown);

$crud->display_as('group_id','Group Name');

// Making field hidden to post value.

//$crud->field_type ( "group_id", "hidden" );

$crud->field_type ( "username", "hidden" );

$crud->field_type ( "password", "hidden" );

$crud->field_type ( "user_type", "hidden", "supplier" );

// removing view option from record.

$crud->unset_read ();

//$crud->unset_export ();

$crud->unset_print ();

// Custom update function.

$crud->callback_before_insert ( array (

$this,

'add_user'

) );

// Custom Email Sending function.

$crud->callback_after_insert ( array (

$this,

'send_email_supplier'

) );

//$crud->limit(1);

// $crud->callback_column("s")

$output = $crud->render ();

echo "<pre>";

print_r($output);exit;

$is_admin = false;

if ($user_type === "admin") {

$is_admin = true;

}

$output->is_admin = $is_admin;

// $usertype ['is_admin'] = $is_admin;

$this->_example_output ( $output );

} catch ( Exception $e ) {

show_error ( $e->getMessage () . ' --- ' . $e->getTraceAsString () );

}
