Magento Adicionar regra de condição em um formulário personalizado no magento 2

Quero adicionar ação de condição no formulário de administração do módulo personalizado. Como posso conseguir isso?

Consulte o link para Magento 1.9

Substituição do link acima para Magento 2.

Para adicionar um campo condicional ao modelo padrão (e utilizá-lo ainda mais para fins de validação), você precisará criar um novo modelo (ou modificar o existente) que contém esses campos.

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();
    }
}

Agora, temos uma tabela com a descrição do modelo e precisamos concluir o próprio modelo e incluir nele o modelo e a coleção de recursos apropriados.

O modelo será chamado de 'Regra':

app / code / Vendor / Rules / Model / Rule.php

<?php

        $this->condProdCombineF = $condProdCombineF;
        parent::__construct($context, $registry, $formFactory, $localeDate, $resource, $resourceCollection, $data);
    }

    {
        parent::_construct();
        $this->_init('Vendor\Rules\Model\ResourceModel\Rule');
        $this->setIdFieldName('rule_id');
    }

    }

    }

    /**

        if ($address instanceof Address) {
            return $address->getId();
        }
        return $address;
    }
}

Como você pode ver, nosso modelo é herdado do Magento\Rule\Model\AbstractModelmodelo que já possui todos os métodos necessários.

No Construtor, adicionaremos fábricas de condições que nos permitem trabalhar com eles e criar vários métodos. Isso deve nos dar a compreensão de como o modelo funciona.

Observe que estamos usando os modelos de condição padrão do \Magento\SalesRule\Model\Rule\Conditionmódulo Magento SalesRule ( ). Se você precisar expandir as condições, poderá adicionar suas próprias classes e / ou reescrevê-las completamente ou herdar das classes disponíveis básicas. In pode ser útil quando você deseja adicionar uma condição especial que não está incluída nas condições padrão. Por exemplo, subtotal com desconto .

....

Em seguida, vamos mudar para a interface no painel de administração. Precisamos do Controller com um conjunto de ações (como Salvar, Adicionar, Editar, Exibição em grade, Recarregar condições) e um layout com blocos.

Vamos começar com o próprio controlador. Primeiro, declare o controlador comum:

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');
    }
}

Aqui, precisamos chamar a fábrica de nossos modelos no Constructor. Isso é feito para disponibilizá-las publicamente (e algumas classes auxiliares, como um registro e um criador de logs).

O _initRulemétodo é responsável pela inicialização da regra atual ou pela criação de uma nova e vazia, com a capacidade de adicioná-la ao registro. O _initAction()método carrega um layout e disponibiliza o menu dos módulos para ações (além de adicionar trilhas). O _isAllowed()método verifica se o administrador atual tem acesso ao Controlador.

Na próxima etapa, adicionaremos as ações padrão:

....

Edição:

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();
    }
}

Eis como adicionar novas condições:

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);
    }
}

Essa classe é responsável por carregar as condições que foram escolhidas na interface (todas as condições não podem ser carregadas de uma só vez).

....

Em seguida, precisamos criar todos os blocos e layout necessários.

Agora, vamos começar a criar e editar novas regras. Vamos criar o bloco de contêiner principal para edição:

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');
        }
    }

}

Quando terminar, devemos adicionar o título dos controladores e os botões savee edit current modelno Construtor. Além disso, aqui você deve adicionar o texto principal do bloco.

Este é um formulário em si:

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();
    }
}

e guias:

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'));
    }
}

Teremos as duas guias: informações e condições do modelo Ceneral.
