Magento 2 : Product Attribute Rule Conditions

Question

I have added following field in my UI Component Form in a custom module to get the Product Attributes ** in conditions, but the options given in the drop-down are **Cart Attributes whereas I need Product Attributes!

Here is my code,

<fieldset name="conditions">
    <argument name="data" xsi:type="array">
        <item name="config" xsi:type="array">
            <item name="label" xsi:type="string" translate="true">Products with Conditions</item>
            <item name="collapsible" xsi:type="boolean">true</item>
            <item name="sortOrder" xsi:type="number">127</item>
        </item>
    </argument>
    <container name="conditions_apply_to" >
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="sortOrder" xsi:type="number">10</item>
            </item>
        </argument>
        <htmlContent name="html_content">
            <argument name="block" xsi:type="object">Magento\SalesRule\Block\Adminhtml\Promo\Quote\Edit\Tab\Conditions</argument>
        </htmlContent>
    </container>
</fieldset>

How can I change this?

Answer 1

You need replace follow lines in file app/code/Vendor/Rules/Model/Rule.php

Find this:

\Magento\SalesRule\Model\Rule\Condition\CombineFactory $condCombineFactory,
\Magento\SalesRule\Model\Rule\Condition\Product\CombineFactory $condProdCombineF,

Replace with:

\Magento\CatalogWidget\Model\Rule\Condition\CombineFactory $condCombineFactory,
\Magento\CatalogWidget\Model\Rule\Condition\ProductFactory $condProdCombineF,

Answer 2

You are using SalesRule, you need to use CatalogRule.

You can extends from \Magento\Backend\Block\Widget\Form\Generic.

You need your conditions class with a constructor and method. This is an example of how it could be:

 /**
 * Constructor
 *
 * @param \Magento\Backend\Block\Template\Context $context
 * @param \Magento\Framework\Registry $registry
 * @param \Magento\Framework\Data\FormFactory $formFactory
 * @param \Magento\Rule\Block\Conditions $conditions
 * @param \Magento\Backend\Block\Widget\Form\Renderer\Fieldset $rendererFieldset
 * @param array $data
 * @param \Magento\SalesRule\Model\RuleFactory|null $ruleFactory
 */
public function __construct(
    \Magento\Backend\Block\Template\Context $context,
    \Magento\Framework\Registry $registry,
    \Magento\Framework\Data\FormFactory $formFactory,
    \Magento\Rule\Block\Conditions $conditions,
    \Magento\Backend\Block\Widget\Form\Renderer\Fieldset $rendererFieldset,
    array $data = [],
    \Magento\CatalogRule\Model\RuleFactory $ruleFactory = null
) {
    $this->_rendererFieldset = $rendererFieldset;
    $this->_conditions = $conditions;
    $this->ruleFactory = $ruleFactory ?: ObjectManager::getInstance()
        ->get(\Magento\CatalogRule\Model\RuleFactory::class);
    parent::__construct($context, $registry, $formFactory, $data);
}

/**
 * Handles addition of conditions tab to supplied form.
 *
 * @param \Magento\SalesRule\Model\Rule $model
 * @param string $fieldsetId
 * @param string $formName
 * @return \Magento\Framework\Data\Form
 * @throws \Magento\Framework\Exception\LocalizedException
 */
protected function addTabToForm($model, $fieldsetId = 'conditions_fieldset', $formName = 'sales_rule_form')
{
    if (!$model) {
        $id = $this->getRequest()->getParam('id');
        $model = $this->ruleFactory->create();
        $model->load($id);
    }
    $conditionsFieldSetId = $model->getConditionsFieldSetId($formName);
    $newChildUrl = $this->getUrl(
        'catalog_rule/promo_catalog/newConditionHtml/form/' . $conditionsFieldSetId,
        ['form_namespace' => $formName]
    );

    /** @var \Magento\Framework\Data\Form $form */
    $form = $this->_formFactory->create();
    $form->setHtmlIdPrefix('rule_');
    $renderer = $this->_rendererFieldset->setTemplate(
        'Magento_CatalogRule::promo/fieldset.phtml'
    )->setNewChildUrl(
        $newChildUrl
    )->setFieldSetId(
        $conditionsFieldSetId
    );

    $fieldset = $form->addFieldset(
        $fieldsetId,
        [
            'legend' => __(
                'Apply the rule only if the following conditions are met (leave blank for all products).'
            )
        ]
    )->setRenderer(
        $renderer
    );
    $fieldset->addField(
        'conditions',
        'text',
        [
            'name'           => 'conditions',
            'label'          => __('Conditions'),
            'title'          => __('Conditions'),
            'required'       => true,
            'data-form-part' => $formName
        ]
    )->setRule(
        $model
    )->setRenderer(
        $this->_conditions
    );

    $form->setValues($model->getData());
    $this->setConditionFormName($model->getConditions(), $formName);
    return $form;
}
