If you want to add country and region inside the drop-down in custom module admin form, you landed to right page.
Follow below instruction step-by-step to execute it.
Step 1 : Add column in table field.
Create new file : Setup/Installschema.php
<?php
->addColumn(
'country',
\Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
'2M',
['nullable' => false],
'country'
)->addColumn(
'store_ids',
\Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
'255',
['nullable' => false,
'default' => $defaultstoreid,
],
'store_ids'
)->addColumn(
'statename',
\Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
'2M',
['nullable' => false],
'statename'
)
?>
Step 2 : Add country and state drop-down with text
Create new file : Block/Adminhtml/Grid/Edit/Form.php
<?php
$optionsc=$this->_countryFactory->toOptionArray();
$country = $fieldset->addField(
'country',
'select',
[
'name' => 'country',
'label' => __('Country'),
'title' => __('country'),
'values' => $optionsc,
]
);
$statename = $fieldset->addField(
'state',
'select',
[
'name' => 'state',
'label' => __('State'),
'id' => 'state',
'title' => __('state'),
'class' => 'required-entry',
'required' => false,
'values' => ['--Please Select State--'],
]
);
$fieldset->addField(
'statename',
'text',
[
'name' => 'statename',
'label' => __('State'),
'id' => 'statename',
'title' => __('state'),
'class' => 'statename',
'required' => false,
]
);
/*
* Add Ajax to the Country select box html output
*/
$country->setAfterElementHtml("
<script type=\"text/javascript\">
require([
'jquery',
'mage/template',
'jquery/ui',
'mage/translate'
],
function($, mageTemplate) {
jQuery('.field-statename').hide();
jQuery('#addressbook_country').change(function(){
var conceptName = jQuery('#addressbook_country').find(':selected').val();
jQuery.ajax({
url : '". $this->getUrl('grid/lists/regionlist') . "?country=' + conceptName,
data: conceptName,
type: 'GET',
dataType: 'json',
showLoader:true,
success: function(data){
// console.log(data.htmlconent);
if(data.htmlconent==''){
jQuery('.field-statename').show();
jQuery('.field-state').hide();
}else{
jQuery('#addressbook_state').empty().append(data.htmlconent);
jQuery('.field-state').show();
jQuery('.field-statename').hide();
}
}
});
});
}
);
</script>"
);
$statename->setAfterElementHtml("
<script type=\"text/javascript\">
require([
'jquery',
'mage/template',
'jquery/ui',
'mage/translate'
],
function($, mageTemplate) {
jQuery('.field-statename').hide();
jQuery(window).load(function(){
setTimeout(function(){
var statename ='".$model->getState()."';
jQuery('#addressbook_state option').each(function (a, b) {
if (jQuery(this).text().toLowerCase() == statename.toLowerCase() ){
jQuery(this).attr('selected','selected');
jQuery(this).trigger('change');
}
});
}, 1000);
});
var conceptName = jQuery('#addressbook_country').find(':selected').val();
if(conceptName != ''){
jQuery('#addressbook_country').trigger('change');
}
}
);
</script>"
);
?>
Step 3 : Getting region list from controller.
Create new file : Controller/Adminhtml/Lists/Regionlist.php
/**
* @SuppressWarnings(PHPMD.CouplingBetweenObjects)
*/
class Regionlist extends \Magento\Framework\App\Action\Action
{
/**
* @var \Magento\Framework\View\Result\PageFactory
*/
protected $resultPageFactory;
/**
* @var \Magento\Directory\Model\CountryFactory
*/
protected $_countryFactory;
/**
* @param \Magento\Framework\App\Action\Context $context
* @param \Magento\Framework\View\Result\PageFactory resultPageFactory
*/
public function __construct(
\Magento\Framework\App\Action\Context $context,
\Magento\Directory\Model\CountryFactory $countryFactory,
\Magento\Framework\View\Result\PageFactory $resultPageFactory
)
{
$this->_countryFactory = $countryFactory;
$this->resultPageFactory = $resultPageFactory;
parent::__construct($context);
}
/**
* Default customer account page
*
* @return void
*/
public function execute()
{
$countrycode = $this->getRequest()->getParam('country');
if ($countrycode != '') {
$statearray =$this->_countryFactory->create()->setId($countrycode)->getLoadedRegionCollection()->toOptionArray();
$state = '';
if(count($statearray) > 0){
// $state .= "<option value=''>--Please Select State--</option>";
foreach ($statearray as $_state) {
if($_state['value']){
$state .= "<option value=".$_state['label'].">" . $_state['label'] . "</option>";
}
}
}
}
$result['htmlconent']=$state;
$this->getResponse()->representJson(
$this->_objectManager->get('Magento\Framework\Json\Helper\Data')->jsonEncode($result)
);
}
}
?>
Step 4 : Save your data.
Create new file : Controller/Adminhtml/Grid/Save.php
<?php
class Save extends \Magento\Backend\App\Action
{
/**
* @var \Namespace\Modulename\Model\GridFactory
*/
var $gridFactory;
/**
* @param \Magento\Backend\App\Action\Context $context
* @param \Namespace\Modulename\Model\GridFactory $gridFactory
*/
public function __construct(
\Magento\Backend\App\Action\Context $context,
\Namespace\Modulename\Model\GridFactory $gridFactory,
\Magento\Directory\Model\CountryFactory $countryFactory
) {
parent::__construct($context);
$this->gridFactory = $gridFactory;
$this->_countryFactory = $countryFactory;
}
/**
* @SuppressWarnings(PHPMD.CyclomaticComplexity)
* @SuppressWarnings(PHPMD.NPathComplexity)
*/
public function execute()
{
$data = $this->getRequest()->getPostValue();
if (!$data) {
$this->_redirect('grid/grid/addrow');
return;
}
try {
$countrycode = $data['country'];
$statearray =$this->_countryFactory->create()->setId($countrycode)->getLoadedRegionCollection()->toOptionArray();
$rowData = $this->gridFactory->create();
if($data['state'] == '0' || count($statearray) == 0){
$data['state'] = $data['statename'];
}
$data['store_ids'] = implode(',', $data['store_ids']);
$rowData->setData($data);
if (isset($data['id'])) {
$rowData->setEntityId($data['id']);
}
$rowData->save();
$this->messageManager->addSuccess(__('AddressBook has been successfully saved.'));
} catch (\Exception $e) {
$this->messageManager->addError(__($e->getMessage()));
}
$this->_redirect('grid/grid/index');
}
/**
* @return bool
*/
protected function _isAllowed()
{
return $this->_authorization->isAllowed('Namespace_Modulename::save');
}
}
?>
