In Topic: [updated 24/11/2012] Dependent dropdown (library)

04 April 2014 - 10:27 AM



I am using this library to make something like category and subcategory. But I am not getting proper value in select boxes of category and sub category. Below is my code, can anyone please check my code and tell me, where I am doing wrong.


In my example the themes are as category and subthemes are as subcategory.

	function check_theme ()
		$crud = new grocery_CRUD();
		$crud->set_relation('article_theme_id', 'themes', 'theme_name');
		$crud->set_relation('article_subtheme_id', 'sub_themes', 'subtheme_name');

		// settings

		$fields = array(

		// first field:
		'Themes' => array( // first dropdown name
		'table_name' => 'themes', // table of country
		'title' => 'theme_name', // country title
		'relate' => null // the first dropdown hasn't a relation
		// second field
		'SubThemes' => array( // second dropdown name
		'table_name' => 'sub_themes', // table of state
		'title' => 'subtheme_name', // state title
		'id_field' => 'subtheme_id', // table of state: primary key
		'relate' => 'theme_ids', // table of state:
		'data-placeholder' => 'select subthem' //dropdown's data-placeholder:


		$config = array(
		'main_table' => 'articles',
		'main_table_primary' => 'article_id',
		"url" => base_url().'index.php/'.__CLASS__.'/'.__FUNCTION__.'/', //path to method
		'ajax_loader' => base_url().'img/ajax-loaders/ajax-loader-2.gif', // path to ajax-loader image. It's an optional parameter
		'segment_name' =>'Your_segment_name' // It's an optional parameter. by default "get_items"
		$categories = new gc_dependent_select($crud, $fields, $config);

		// first method:
		//$output = $categories->render();

		// the second method:
		$js = $categories->get_js();
		$output = $crud->render();
		$output->output.= $js;

Here is the screenshots of my above code. By default its showing all records of themes and subthemes. But I want only those subtheme which theme selected from the theme dropdown.





Thanks for your help.! :)

In Topic: callback_before_insert not working for created date

21 March 2014 - 03:57 PM

Hi Amit,


Thanks for your help.


I changed type to hidden but still it's not working. Note that, the data type of field is date so I got my mistake and changed date format to 

$post_array['nt_created_dt'] = date('Y-m-d');

I thought it will work now after corrected the date format, but still no use. 


can you please check again my code?

Finally, I got the solution. which is as below. 

function delete_thumb($primary_key)
		$user= $this->db->where('member_id',$primary_key)->get('member')->row();
		$url= 'assets/uploads/files/'.$user->profile_photo;
		$thumb_url= 'assets/uploads/files/thumb1-'.$user->profile_photo;

	    return true;

I hope it may help someone who is facing issue for deleting image.
