How to get all the attributes on Admin Ui Component

[tvgarden]

Hi,

I am making an admin form includes a select of attribute values. My code is returning an empty select.

<field name="group">
    <argument name="data" xsi:type="array">
        <item name="options" xsi:type="object">Vendor\Module\Model\Source\Myvalues</item>
        <item name="config" xsi:type="array">
            <item name="dataType" xsi:type="string">text</item>
            <item name="label" translate="true" xsi:type="string">Attribute</item>
            <item name="formElement" xsi:type="string">select</item>
        </item>
    </argument>
</field>

I have created Myvalues.php

<?php

namespace Vendor\Module\Model\Source;
    use Magento\Store\Model\StoreManagerInterface;
    use Magento\Framework\App\Filesystem\DirectoryList;
use Magento\Catalog\Model\ResourceModel\Product\Attribute\CollectionFactory;

class Myvalues implements \Magento\Framework\Option\ArrayInterface
{
        public function __construct(
            CollectionFactory $collectionFactory,
            \Magento\Framework\ObjectManagerInterface $objectManager
        ) {
           $this->_collectionFactory = $collectionFactory;
            $this->_objectManager = $objectManager;
        }


    public function toOptionArray()
    {
		$attributes = $this->getAttributes();
        return  $attributes;
    }



            public function getAttributes() {
                    $collection = $this->_collectionFactory->create();
                    $attr_groups = array();
                    foreach ($collection as $items) {
                        $attr_groups[] = $items->getData();
                    }

                    return $attr_groups; 
    }


 
 
}

I would like to know how to get a collection of attributes in default attribute set.

Hello @tvgarden

<?php

    /** @var  $coll \Magento\Eav\Model\ResourceModel\Entity\Attribute\Collection */
    $coll = $this->_objectManager->create(\Magento\Eav\Model\ResourceModel\Entity\Attribute\Collection::class);
    // add filter by entity type to get product attributes only
    // '4' is the default type ID for 'catalog_product' entity - see 'eav_entity_type' table)
    // or skip the next line to get all attributes for all types of entities
    $coll->addFieldToFilter(\Magento\Eav\Model\Entity\Attribute\Set::KEY_ENTITY_TYPE_ID, 4);
    $attrAll = $coll->load()->getItems();

hope it will help you.

If works then mark as solution.

HI @Sunil Patel

Thanks I used your code but it's not getting any options.

Spoiler

<?php

namespace Vendor\Module\Model\Source;
    use Magento\Store\Model\StoreManagerInterface;
    use Magento\Framework\App\Filesystem\DirectoryList;
    use Magento\Catalog\Model\ResourceModel\Product\Attribute\CollectionFactory;

class Myvalues implements \Magento\Framework\Option\ArrayInterface
{


        public function __construct(
 
            CollectionFactory $collectionFactory,
            \Magento\Framework\ObjectManagerInterface $objectManager
        ) {
        	 $this->_collectionFactory = $collectionFactory;
            $this->_objectManager = $objectManager;
        }


    public function toOptionArray()
    {

		$categories = $this->getCategoriesTree();
		$attributes = $this->getAttributes();

        return  $attributes;
    }



    public function getAttributes() {
        
         $collection = $this->_collectionFactory->create();
         
  /** @var  $coll \Magento\Eav\Model\ResourceModel\Entity\Attribute\Collection */
    $coll = $this->_objectManager->create(\Magento\Eav\Model\ResourceModel\Entity\Attribute\Collection::class);
    // add filter by entity type to get product attributes only
    // '4' is the default type ID for 'catalog_product' entity - see 'eav_entity_type' table)
    // or skip the next line to get all attributes for all types of entities
    $coll->addFieldToFilter(\Magento\Eav\Model\Entity\Attribute\Set::KEY_ENTITY_TYPE_ID, 4);
    $attrAll = $coll->load()->getItems();

         
         $attr_groups = array();
          
        foreach ($collection as $items) {
            $attr_groups[] = $items->getData();
        }

        return $attrAll; //This will give you the collection of all the attributes which are available in that magento instance
    }


    public function getCategoriesTree()
        {
            $categories = $this->_objectManager->create(
                'Magento\Catalog\Ui\Component\Product\Form\Categories\Options'
            )->toOptionArray();
            return $categories;
        }


}

Hi,

I have made it work:

    public function getAttributes() {
        
         $collection = $this->_collectionFactory->create();
         
         $attr_groups = array();
          
        foreach ($collection as $item) {
         $attr_groups[] = ['value' => $item->getData()['attribute_id'], 'label' => $item->getData()['frontend_label']];
        }

        return $attr_groups; 
    }
