How to get an option value based on the option id in Magento, or get an option id based on the option code ?

Example: how to get the color attribute option id 10 from the label "Red", and get the value "Red" if the option id is 10 ?

Answer 1

you can do it same as magento 1,

More information in details, Visit, Get Option id and Label from configurable product

//get option label based on option id from product object

$optionId = 10;

$attr = $_product->getResource()->getAttribute('color');
 if ($attr->usesSource()) {
       $optionText = $attr->getSource()->getOptionText($optionId);
 }
//get option text ex. Red

//get option id based on option label

$attr = $_product->getResource()->getAttribute('color');
 if ($attr->usesSource()) {
       $option_id = $attr->getSource()->getOptionId("Red");
 }

//get option id ex. 10

Thanks.

Best practice in magento is to do it via xml.

To get a standard attribute like brand you do something like this in catalog_product_view.xml for example:

<referenceBlock name="product.info.main">
    <block class="Magento\Catalog\Block\Product\View\Description" name="product.info.brand" template="product/view/attribute.phtml" before="-">
        <arguments>
            <argument name="at_call" xsi:type="string">getBrand</argument>
            <argument name="at_code" xsi:type="string">brand</argument>
            <argument name="css_class" xsi:type="string">brand</argument>
            <argument name="at_label" xsi:type="string">none</argument>
            <argument name="add_attribute" xsi:type="string">itemprop="brand"</argument>
        </arguments>
    </block>
</referenceBlock>

This will get the value of an input attribute or textarea. If you have a dropdown you should use the text type, so add this line in the list of arguments:

<argument name="at_type" xsi:type="string">text</argument>

No need to create files or write any php code to get an attribute. This way you will have consistency and use the same attribute.phtml file for all attributes. If something changes you need to change it in one place only.

Worked for me

$_product->getResource()->getAttribute('your_attribute_code')->getFrontend()->getValue($_product);

Answer 4

Use Factory Method

   protected $_attributeLoading;

   public function __construct( 
        .....
          \Magento\Catalog\Model\ResourceModel\ProductFactory   $attributeLoading,  
          ....
                                ) {
            parent::__construct($context);

            ....
            $this->_attributeLoading = $attributeLoading;
            ....

    }


   public function getAttributeOptionId($attribute,$label)
    {
        $poductReource=$this->_attributeLoading->create();
        $attr = $poductReource->getAttribute($attribute);
         if ($attr->usesSource()) {
                return  $option_id = $attr->getSource()->getOptionId($label);
         }
    }
   public function getAttributeOptionText($attribute,$label)
    {
        $poductReource=$this->_attributeLoading->create();
        $attr = $poductReource->getAttribute($attribute);
         if ($attr->usesSource()) {
                return  $option_Text = $attr->getSource()->getOptionText($label);
         }
    }

in phtml file

  $this->getAttributeOptionId('color','//optionLabel');
  $this->getAttributeOptionText('color','//optionId');

Answer 5

$product->getResource() has a DocBlock note about being deprecated at least in v2.2.2 and so I was hesitant to code using it. Came up with this solution instead inspired by the ones already on this page:

$optionId = $product->getDataByKey('attribute_code');
$optionText = null;
$attributes = $product->getAttributes();
if ($optionId && array_key_exists('attribute_code', $attributes)) {
    $attr = $attributes['attribute_code'];
    if ($attr->usesSource()) {
        $optionText = $attr->getSource()->getOptionText($optionId);
    }
}
if ($optionText) {
    //do something with $optionText
}

For reference this is the method in AbstractModel.php

/**
 * Retrieve model resource
 *
 * @return \Magento\Framework\Model\ResourceModel\Db\AbstractDb
 * @deprecated 101.0.0 because resource models should be used directly
 */
public function getResource()
{
    return $this->_getResource();
}

Answer 6

i get a simple solution. this will only show the attribute value with the attribute code for a product. i have checked in catalog and details page.

the code is

<?php echo $_product->getAttributeText('size'); ?>

here size is the attribute name.

reference: vendor/magento/module-catalog/view/frontend/templates/product/view/attribute.phtml line: 35

Answer 7

Please try this code

Step 1)First you have to load the products

$_productCollection = $block->getLoadedProductCollection();

Step 2)In the product listing page ,there will be a foreach loop for listing the products like this

foreach ($_productCollection as $_product)

Step3)Your code will be inside this loop.Place the below code at a place whereever you want to display the attribute label.

$_product->getResource()->getAttribute('your_attribute_code')->getFrontend()->getValue($_product);

Just replace your_attribute_code with whatever your attribute is named.
