conditions-serializedmagento2
I was add a condition action in custom module admin form in magento 2
I used this blog to create a condition action: https://www.mageworx.com/blog/2016/09/magento-2-module-with-conditions-model-fieldset/
Database:
how we can apply those saved condition in the frontend?
To add a conditional field to the default model (and further utilize it for validating purposes), you will need to create a new model (or modify the existing one) that contains these fields.
app/code/Vendor/Rules/Setup/InstallSchema.php
<?php
namespace Vendor\Rules\Setup;
use Magento\Framework\DB\Ddl\Table;
use Magento\Framework\Setup\InstallSchemaInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\SchemaSetupInterface;
class InstallSchema implements InstallSchemaInterface
{
public function install(SchemaSetupInterface $setup, ModuleContextInterface $context)
{
$installer = $setup;
$installer->startSetup();
$table = $installer->getConnection()->newTable(
$installer->getTable('vendor_rules')
)->addColumn(
'rule_id',
Table::TYPE_INTEGER,
null,
['identity' => true, 'unsigned' => true, 'nullable' => false, 'primary' => true],
'Rule Id'
)->addColumn(
'name',
Table::TYPE_TEXT,
255,
[],
'Name'
)->addColumn(
'description',
Table::TYPE_TEXT,
'64k',
[],
'Description'
)->addColumn(
'from_date',
Table::TYPE_DATE,
null,
['nullable' => true, 'default' => null],
'From'
)->addColumn(
'to_date',
Table::TYPE_DATE,
null,
['nullable' => true, 'default' => null],
'To'
)->addColumn(
'is_active',
Table::TYPE_SMALLINT,
null,
['nullable' => false, 'default' => '0'],
'Is Active'
)->addColumn(
'conditions_serialized',
Table::TYPE_TEXT,
'2M',
[],
'Conditions Serialized'
)->addColumn(
'sort_order',
Table::TYPE_INTEGER,
null,
['unsigned' => true, 'nullable' => false, 'default' => '0'],
'Sort Order (Priority)'
)->addIndex(
$installer->getIdxName('vendor_rules', ['sort_order', 'is_active', 'to_date', 'from_date']),
['sort_order', 'is_active', 'to_date', 'from_date']
)->setComment(
'Own Rules'
);
$installer->getConnection()->createTable($table);
$installer->endSetup();
}
}
Now, we have a table with the model description and we need to complete the model itself, and include into it the appropriate resource model and collection.
The model will be called 'Rule':
app/code/Vendor/Rules/Model/Rule.php
<?php
namespace Vendor\Rules\Model;
use Magento\Quote\Model\Quote\Address;

{
if ($address instanceof Address) {
return $address->getId();
}
return $address;
}
}
As you can see, our model inherits from the Magento\Rule\Model\AbstractModel model that already has all the required methods.
Right in the Constructor, we'll add condition factories that allow us to work with them and create multiple methods. This should give us the understanding of how the model works.
Note that we are using the default condition models from the Magento SalesRule (\Magento\SalesRule\Model\Rule\Condition) module. If you need to expand the conditions, you can add your own clasees and/or rewrite them completely or inherit from the base available classes. In can be useful when you want to add a special condition that is not included in the default conditions. For example, Subtotal With Discount.
....
Next, let's switch to the interface in the admin panel. We need the Controller with a set of actions (such as Save, Add, Edit, Grid Display, Conditions reload) and a layout with blocks.
Let's start with the Controller itself. First, declare the common Controller:
app/code/Vendor/Rules/Controller/Adminhtml/Example/Rule.php
<?php
namespace Vendor\Rules\Controller\Adminhtml\Example;
abstract class Rule extends \Magento\Backend\App\Action
{
/**
* Core registry
*
* @var \Magento\Framework\Registry
*/
protected $coreRegistry = null;
/**
* @var \Magento\Framework\App\Response\Http\FileFactory
*/
protected $fileFactory;
/**
* @var \Magento\Framework\Stdlib\DateTime\Filter\Date
*/
protected $dateFilter;
/**
* @var \Vendor\Rules\Model\RuleFactory
*/
protected $ruleFactory;
/**
* @var \Psr\Log\LoggerInterface
*/
protected $logger;
/**
* @param \Magento\Backend\App\Action\Context $context
* @param \Magento\Framework\Registry $coreRegistry
* @param \Magento\Framework\App\Response\Http\FileFactory $fileFactory
* @param \Magento\Framework\Stdlib\DateTime\Filter\Date $dateFilter
* @param \Vendor\Rules\Model\RuleFactory $ruleFactory
* @param \Psr\Log\LoggerInterface $logger
*/
public function __construct(
\Magento\Backend\App\Action\Context $context,
\Magento\Framework\Registry $coreRegistry,
\Magento\Framework\App\Response\Http\FileFactory $fileFactory,
\Magento\Framework\Stdlib\DateTime\Filter\Date $dateFilter,
\Vendor\Rules\Model\RuleFactory $ruleFactory,
\Psr\Log\LoggerInterface $logger
) {
parent::__construct($context);
$this->coreRegistry = $coreRegistry;
$this->fileFactory = $fileFactory;
$this->dateFilter = $dateFilter;
$this->ruleFactory = $ruleFactory;
$this->logger = $logger;
}
/**
* Initiate rule
*
* @return void
*/
protected function _initRule()
{
$rule = $this->ruleFactory->create();
$this->coreRegistry->register(
'current_rule',
$rule
);
$id = (int)$this->getRequest()->getParam('id');
if (!$id && $this->getRequest()->getParam('rule_id')) {
$id = (int)$this->getRequest()->getParam('rule_id');
}
if ($id) {
$this->coreRegistry->registry('current_rule')->load($id);
}
}
/**
* Initiate action
*
* @return Rule
*/
protected function _initAction()
{
$this->_view->loadLayout();
$this->_setActiveMenu('Vendor_Rules::vendor_rules')
->_addBreadcrumb(__('Example Rules'), __('Example Rules'));
return $this;
}
/**
* Returns result of current user permission check on resource and privilege
*
* @return bool
*/
protected function _isAllowed()
{
return $this->_authorization->isAllowed('Vendor_Rules::rules');
}
}
Here, we need to call out our models' factory in the Constructor. That is done to make them (and some auxiliary classes, like a register and a logger) publicy available.
The _initRule method is responsible for the current rule initialization or creating of a new and empty one with the ability of adding it to the register.
The _initAction() method loads a layout and makes the modules' menu available for actions (also, it adds breadcumbs).
The _isAllowed() method checks if the current admin has an access to the Controller.
At the next step, we are going to add the default actions:
....
Editing:
app/code/Vendor/Rules/Controller/Adminhtml/Example/Rule/Edit.php
<?php
namespace Vendor\Rules\Controller\Adminhtml\Example\Rule;
class Edit extends \Vendor\Rules\Controller\Adminhtml\Example\Rule
{
/**
* Rule edit action
*
* @return void
*/
public function execute()
{
$id = $this->getRequest()->getParam('id');
/** @var \Vendor\Rules\Model\Rule $model */
$model = $this->ruleFactory->create();
if ($id) {
$model->load($id);
if (!$model->getRuleId()) {
$this->messageManager->addErrorMessage(__('This rule no longer exists.'));
$this->_redirect('vendor_rules/*');
return;
}
}
// set entered data if was error when we do save
$data = $this->_session->getPageData(true);
if (!empty($data)) {
$model->addData($data);
}
$model->getConditions()->setJsFormObject('rule_conditions_fieldset');
$this->coreRegistry->register('current_rule', $model);
$this->_initAction();
$this->_view->getLayout()
->getBlock('example_rule_edit')
->setData('action', $this->getUrl('vendor_rules/*/save'));
$this->_addBreadcrumb($id ? __('Edit Rule') : __('New Rule'), $id ? __('Edit Rule') : __('New Rule'));
$this->_view->getPage()->getConfig()->getTitle()->prepend(
$model->getRuleId() ? $model->getName() : __('New Rule')
);
$this->_view->renderLayout();
}
}
This is how to add new conditions:
app/code/Vendor/Rules/Controller/Adminhtml/Example/Rule/NewConditionHtml.php
<?php
namespace Vendor\Rules\Controller\Adminhtml\Example\Rule;
class NewConditionHtml extends \Vendor\Rules\Controller\Adminhtml\Example\Rule
{
/**
* New condition html action
*
* @return void
*/
public function execute()
{
$id = $this->getRequest()->getParam('id');
$typeArr = explode('|', str_replace('-', '/', $this->getRequest()->getParam('type')));
$type = $typeArr[0];
$model = $this->_objectManager->create(
$type
)->setId(
$id
)->setType(
$type
)->setRule(
$this->ruleFactory->create()
)->setPrefix(
'conditions'
);
if (!empty($typeArr[1])) {
$model->setAttribute($typeArr[1]);
}
if ($model instanceof \Magento\Rule\Model\Condition\AbstractCondition) {
$model->setJsFormObject($this->getRequest()->getParam('form'));
$html = $model->asHtmlRecursive();
} else {
$html = '';
}
$this->getResponse()->setBody($html);
}
}
This class is responsible for loading the conditions that have been chosen in the interface (all the conditions can't be loaded at once).
....
Next, we need to create all the required blocks and layout.
Now, let's get down to creating and editing new rules. Let's create the main container block for editing:
app/code/Vendor/Rules/Block/Adminhtml/Example/Rule/Edit.php
<?php
namespace Vendor\Rules\Block\Adminhtml\Example\Rule;
class Edit extends \Magento\Backend\Block\Widget\Form\Container
{
/**
* Core registry
*
* @var \Magento\Framework\Registry
*/
protected $coreRegistry = null;
/**
* @param \Magento\Backend\Block\Widget\Context $context
* @param \Magento\Framework\Registry $registry
* @param array $data
*/
public function __construct(
\Magento\Backend\Block\Widget\Context $context,
\Magento\Framework\Registry $registry,
array $data = []
) {
$this->coreRegistry = $registry;
parent::__construct($context, $data);
}
/**
* Initialize form
* Add standard buttons
* Add "Save and Continue" button
*
* @return void
*/
protected function _construct()
{
$this->_objectId = 'id';
$this->_controller = 'adminhtml_example_rule';
$this->_blockGroup = 'Vendor_Rules';
parent::_construct();
$this->buttonList->add(
'save_and_continue_edit',
[
'class' => 'save',
'label' => __('Save and Continue Edit'),
'data_attribute' => [
'mage-init' => ['button' => ['event' => 'saveAndContinueEdit', 'target' => '#edit_form']],
]
],
10
);
}
/**
* Getter for form header text
*
* @return \Magento\Framework\Phrase
*/
public function getHeaderText()
{
$rule = $this->coreRegistry->registry('current_rule');
if ($rule->getRuleId()) {
return __("Edit Rule '%1'", $this->escapeHtml($rule->getName()));
} else {
return __('New Rule');
}
}
}
When done, we should add the controllers title and the save and edit current model buttons in the Constructor. Also, here you should add the main text for of the block.
This is a form itself:
app/code/Vendor/Rules/Block/Adminhtml/Example/Rule/Edit/Form.php
<?php
namespace Vendor\Rules\Block\Adminhtml\Example\Rule\Edit;
class Form extends \Magento\Backend\Block\Widget\Form\Generic
{
/**
* Constructor
*
* @return void
*/
protected function _construct()
{
parent::_construct();
$this->setId('example_rule_form');
$this->setTitle(__('Rule Information'));
}
/**
* Prepare form before rendering HTML
*
* @return \Magento\Backend\Block\Widget\Form\Generic
*/
protected function _prepareForm()
{
/** @var \Magento\Framework\Data\Form $form */
$form = $this->_formFactory->create(
[
'data' => [
'id' => 'edit_form',
'action' => $this->getUrl('vendor_rules/example_rule/save'),
'method' => 'post',
],
]
);
$form->setUseContainer(true);
$this->setForm($form);
return parent::_prepareForm();
}
}
and tabs:
app/code/Vendor/Rules/Block/Adminhtml/Example/Rule/Edit/Tabs.php
<?php
namespace Vendor\Rules\Block\Adminhtml\Example\Rule\Edit;
class Tabs extends \Magento\Backend\Block\Widget\Tabs
{
/**
* Constructor
*
* @return void
*/
protected function _construct()
{
parent::_construct();
$this->setId('rules_edit_tabs');
$this->setDestElementId('edit_form');
$this->setTitle(__('Rules'));
}
}
We'll have the two tabs: Ceneral model's information and Conditions.
app/code/Vendor/Rules/Block/Adminhtml/Example/Rule/Edit/Tab/Main.php
<?php

In the block constructor, you'll need to enable two classes with the collection of regions and countries. Also, don't forget to add the corresponding fields in there.
Next, apply the standard RegionUpdater from lib/web/varien/form.js. it can be added in any convenient for you way - in our example we're using a child block with the template where it is called (just note that there're some required parameters: country elements, region (text), region (select) and the object that contains data for countries and regions (from the Helper directory).
In case you need to modify the list of countries and regions, do that not only in the form , but also in the data object from RegionUpdater.
Changes in the class of the form block, add new classes to di, the __construct method and make changes to the _prepareForm method.
<?php
/**
* @var \Magento\Directory\Model\Config\Source\Country
*/
protected $_country;
/**
* @var \Magento\Directory\Model\RegionFactory
*/
protected $_regionFactory;
// ... add them in __construct
// ...
// Add next changes in the _prepareForm method
$countries = $this->_country->toOptionArray(false, 'US');
$regionCollection = $this->_regionFactory->create()->getCollection()->addCountryFilter(
$formData['country_id']
);
$regions = $regionCollection->toOptionArray();
$fieldset->addField(
'country_id',
'select',
['name' => 'country_id', 'label' => __('Country'), 'required' => true, 'values' => $countries]
);
$fieldset->addField(
'region_id',
'select',
['name' => 'region_id', 'label' => __('State'), 'values' => $regions]
);
$fieldset->addField(
'region',
'text',
['name' => 'region', 'label' => __('Region')]
);
$fieldset->addField(
'city',
'text',
['name' => 'city', 'label' => __('City')]
);
$this->setChild(
'form_after',
$this->getLayout()->createBlock('Magento\Framework\View\Element\Template')->setTemplate('Vendor_Module::js.phtml')
);
?>
> Vendor_Module::js.phtml
<script>
require([
"jquery",
"mage/adminhtml/form"
], function ($) {
var updater = new RegionUpdater($('[name=country_id]')[0], $('[name=region]')[0], $('[name=region_id]')[0],
<?php echo $this->helper('Magento\Directory\Helper\Data')->getRegionJson() ?>,
'hide'
);
updater.disableRegionValidation();
window.updater = updater;
});
</script>
This is how it works:
1) by default
2) After you select the USD, the text field for the region is hidden (the 5th argument RegionUpdater constructor - this method will be applied to any inactive fields, also it can be hidden or disabled)
3) For Albania, there're no regions by default. Hence, we can see just the text field with hidden regions:
4) For Switzerland, we can see the regions again:
And it it goes without saying that you should make it convenient to use for your clients, as using the Hide method, the filed label is NOT hidden.
But upon the whole, RegionUpdater works well for a non-UI forms of Magento.
P.S. Also note that there's no way to add an updater for cities,as by default, Magento doesn't support the lists of Cities.
Best Answer
Any rule-model could be used this way:
But your rule model must extend the
\Magento\Rule\Model\AbstractModelclass and object which you will validate must have desired data (subtotal in your case, so I suppose it will be instance of\Magento\Quote\Model\Quote\Address).So, an example will be looking like this:
The
$rule->validate()will call this code:
