Today we talk about how in Magento 2 get product attribute by attribute groups. Sometime custom requirement need to show the product attributes by its own groups. So we learn how to get product attribute by their attribute groups. So let’s start it.
Create a block with following injecting class

\Magento\Eav\Model\ResourceModel\Entity\Attribute\Group\CollectionFactory

<?php
namespace QaisarSatti\HelloWorld\Block;

class HelloWorld extends \Magento\Framework\View\Element\Template
{

protected $_productloader;
protected $request;
protected $_groupCollection;

public function __construct(
\Magento\Framework\View\Element\Template\Context $context,
\Magento\Catalog\Model\ProductFactory $_productloader,
\Magento\Eav\Model\ResourceModel\Entity\Attribute\Group\CollectionFactory $_groupCollection,
\Magento\Framework\App\Request\Http $request

) {

$this->_productloader = $_productloader;
$this->request = $request;
$this->_groupCollection = $_groupCollection;
parent::__construct($context);
}
//get the product
public function getLoadProduct()
{
$id=10;

return $this->_productloader->create()->load($id);
}
//Get attribute group id
public function getAttributeGroupId($attributeSetId)
{
$groupCollection = $this->_groupCollection->create();
$groupCollection->addFieldToFilter('attribute_set_id',$attributeSetId);
$groupCollection->addFieldToFilter('attribute_group_name','Grid Attributes');

return $groupCollection->getFirstItem();

}
//Get all attribute groups
public function getAttributeGroups($attributeSetId)
{
$groupCollection = $this->_groupCollection->create();
$groupCollection->addFieldToFilter('attribute_set_id',$attributeSetId);

$groupCollection->setOrder('sort_order','ASC');
return $groupCollection;

}
//get attribute by groups
public function getGroupAttributes($pro,$groupId, $productAttributes){
$data=[];
$no =__('No');
foreach ($productAttributes as $attribute){

if ($attribute->isInGroup($pro->getAttributeSetId(), $groupId) && $attribute->getIsVisibleOnFront() ){
if($attribute->getFrontend()->getValue($pro) && $attribute->getFrontend()->getValue($pro)!='' && $attribute->getFrontend()->getValue($pro)!=$no){
$data[]=$attribute;
}
}

}

return $data;
}

}

Now we use the block code in our phtml file.

$_product=$block->getLoadProduct();
$groupid=$block->getAttributeGroupId($_product->getAttributeSetId());
$attributesgroups=$block->getAttributeGroups($_product->getAttributeSetId());

$productAttributes=$_product->getAttributes();

?>

<?php
foreach ($attributesgroups as $attributesgroup):

$attributes=$block->getGroupAttributes($product,$attributesgroup->getAttributeGroupId(),$productAttributes);

if($attributes){ ?>

<h3 class="col label" scope="row"><?php echo $attributesgroup->getAttributeGroupName() ?></h3>

<div class="additional-attributes-wrapper table-wrapper block">
<table class="data table additional-attributes" id="product-attribute-specs-table">
<tbody>

<?php
foreach ($attributes as $attribute): ?>

<tr>
<td class="col label" scope="row"><?php echo $attribute->getFrontendLabel() ?></td>
<td class="col data feature" data-th="<?php echo $attribute->getFrontendLabel() ?>"><?php /* @escapeNotVerified */ echo $attribute->getFrontend()->getValue($product) ?></td>
</tr>

<?php
endforeach; ?>
</tbody>
</table>
</div>
<?php }
endforeach;

?>
