I am not able to implement dependent drop down in grocery crud.

 

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

 

public function index()

{

// echo GroceryCrud::VERSION;die;

$crud = generate_crud('');

$crud->set_table('routes');

$crud->display_as('category_id','Category'); 

$crud->display_as('subcategory_id','Subcategory'); 

$crud->set_rules('category_id', 'Category','required');  

$crud->set_relation('category_id','categories','{category}');

$crud->set_relation('subcategory_id','subcategories','{subcategory}');

/////////////////////////////////////////////

$fields = array(

// first field:

'category_id' => array( // first dropdown name

'table_name' => 'categories', // table of country

'title' => 'category', // country title

'relate' => null // the first dropdown hasn't a relation

),

// second field

'subcategory_id' => array( // second dropdown name

'table_name' => 'subcategories', // table of state

'title' => 'subcategory', // state title

'id_field' => 'id', // table of state: primary key

'relate' => 'category_id', // table of state:

'data-placeholder' => 'Select Subcategory' //dropdown's data-placeholder:

),

);

 

$config = array(

'main_table' => 'routes',

'main_table_primary' => 'id',

"url" => base_url() . __CLASS__ . '/' . __FUNCTION__ . '/',

);

$categories = new gc_dependent_select($crud, $fields, $config);

$js = $categories->get_js();

$output = $crud->render();

$output->output.= $js;

$this->_example_output($output);

// $this->mViewData['crud_data'] = $crud->render();
