I tweaked the code a little and created a more dynamic and easier way to implement this instead of having to change the jQuery.
Add this to the top of the view:
Replace the Javascript at the bottom with the following:
The code that you pasted at the top you can change to your needs.
For example say you want to load up a cars list by make and model you would use something like this:
I added the dynamic example into the download - example (dynamic).php

Hi,
Thanx for your code...
I implemented this code to in my project, its shows only text box not dropdown list????
I don't know what's the problem?????
Thanx....
I tweaked the code a little and created a more dynamic and easier way to implement this instead of having to change the jQuery.
Add this to the top of the view:
//LOAD CRUD
$crud = new grocery_CRUD();
//SETUP DEPENDENT DROPDOWN
$dependent_dropdown = array(
//GET THE STATE OF THE CURRENT PAGE - E.G LIST | ADD
'state' => $crud->getState(),
//SETUP YOUR DROPDOWNS
//Parent field item always listed first in array, in this case countryID
//Child field items need to follow in order, e.g stateID then cityID
'dropdowns' => array('countryID','stateID','cityID'),
//SETUP URL POST FOR EACH CHILD
//List in order as per above
'url' => array('', site_url().'/examples/get_states/', site_url().'/examples/get_cities/')
);
Replace the Javascript at the bottom with the following:
if($dependent_dropdown['state'] == 'add' || $dependent_dropdown['state'] == 'edit')
//DONT HAVE TO EDIT THE CODE BELOW IF YOU DONT WANNA
echo '$(document).ready(function() {';
for($i = 0; $i <= sizeof($dependent_dropdown['dropdowns'])-1; $i++):
//SET VARIABLES
echo 'var '.$dependent_dropdown['dropdowns'][$i].' = $(\'select[name="'.$dependent_dropdown['dropdowns'][$i].'"]\');';
//HIDE ALL CHILD ITEMS
if($i > 0 && $dependent_dropdown['state'] == 'add') {
echo '$(\'#'.$dependent_dropdown['dropdowns'][$i].'_input_box\').hide();';
}
endfor;
for($i = 1; $i <= sizeof($dependent_dropdown['dropdowns'])-1; $i++):
//CHILD DROPDOWNS
echo $dependent_dropdown['dropdowns'][$i-1].'.change(function() {';
echo 'var select_value = this.value;';
//REMOVE ALL CURRENT OPTIONS FROM CHILD DROPDOWNS
echo $dependent_dropdown['dropdowns'][$i].'.find(\'option\').remove();';
//POST TO A CUSTOM CONTROLLER ADDING OPTIONS | JSON
echo 'var myOptions = "";';
//GET JSON REQUEST OF STATES
echo '$.getJSON(\''.$dependent_dropdown['url'][$i].'\'+select_value, function(data) {';
//APPEND RECEIVED DATA TO STATES DROP DOWN LIST
echo $dependent_dropdown['dropdowns'][$i].'.append(\'\');';
echo '$.each(data, function(key, val) {';
echo $dependent_dropdown['dropdowns'][$i].'.append(';
echo '$(\'\').val(val.value).html(val.property)';
echo ');';
echo '});';
//SHOW CHILD SELECTION FIELD
echo '$(\'#'.$dependent_dropdown['dropdowns'][$i].'_input_box\').show();';
//MAKE SURE CITY STILL HIDDEN INCASE OF COUNTRY CHANGE
for($x = $i+1; $x <= sizeof($dependent_dropdown['dropdowns'])-1; $x++):
echo '$(\'#'.$dependent_dropdown['dropdowns'][$x].'_input_box\').hide();';
endfor;
//RESET JQUERY STYLE OF DROPDOWN LIST WITH NEW DATA
echo $dependent_dropdown['dropdowns'][$i-1].'.each(function(){';
echo '$(this).trigger("liszt:updated");';
echo '});';
echo $dependent_dropdown['dropdowns'][$i].'.each(function(){';
echo '$(this).trigger("liszt:updated");';
echo '});';
echo '});';
echo '});';
endfor;
echo '});';
The code that you pasted at the top you can change to your needs.
For example say you want to load up a cars list by make and model you would use something like this:
//LOAD CRUD
$crud = new grocery_CRUD();
//SETUP DEPENDENT DROPDOWN
$dependent_dropdown = array(
//GET THE STATE OF THE CURRENT PAGE - E.G LIST | ADD
'state' => $crud->getState(),
//SETUP YOUR DROPDOWNS
'dropdowns' => array('make_id','model_id'),
//SETUP URL POST FOR EACH CHILD
//List in order as per above
'url' => array('', site_url().'/examples/get_models/')
);
I added the dynamic example into the download - example (dynamic).php

I Have a problem..in datatables when this view....i use a category an subcategories

I added in a loader image that displays next to the drop down as the child drop down loads.
Example here: http://demo.edynamics.co.za/grocery_crud/index.php/examples/customers_management/add
I also added it to the dynamic view example located in the downloaded file :)
Hi, how if the value is not ID? maybe title or another field on table with varchar value? because i will concat the value of field and i will save to another field.
Example :
I will concat Country_title, State_title, City_title to Address field. And the result value of Address filed : United States, California, City title from concat.
Thanks, Best Regards
Irfan Tanjung

Hello,
Looking the example (http://demo.edynamics.co.za/grocery_crud/index.php/examples/customers_management/add) and the code:
function empty_state_dropdown_select()
{
//CREATE THE EMPTY SELECT STRING
$empty_select = '<select name="stateID" class="chosen-select" data-placeholder="Select State/Province" style="width: 300px; display: none;">';
$empty_select_closed = '</select>';
//GET THE ID OF THE LISTING USING URI
$listingID = $this->uri->segment(4);
...
}
There is something I don't understand.
What is $listingID = $this->uri->segment(4)?
I don't understand what it is and why does it is necesary for?
Thank you.

I could really use this on a project that I am working on. Can you please re-post the tutorial on github or something. Your link has went down.
Thanks!
