Magento – Programmatically Delete Product Attribute Sets

attribute-setmagento2product-attribute

Due to some shoddy code from a previous employee I have inherited a Magento 2 store with thousands of erroneous product attributes and hundreds of attribute sets.

I've been able to delete the attributes and move all the products back on to the Default attribute set, but now I'm left with hundreds of empty, unused product attribute sets that I can't find how to delete easily?

You can remove an attribute set using Magento\Catalog\Api\AttributeSetRepositoryInterface method deleteById

namespace {NameSpace};


class Test
{
    /**
     * @var \Magento\Catalog\Api\AttributeSetRepositoryInterface
     */
    protected $attributeSetRepository;

    public function __construct(
        \Magento\Catalog\Api\AttributeSetRepositoryInterface $attributeSetRepository
    )
    {
        $this->a

ttributeSetRepository = $attributeSetRepository;
        }
        public function deleteAttributeSet()
        {
            $attributeSetId = 15;
            $this->attributeSetRepository->deleteById($attributeSetId);
        }
    }

Via Object manager:

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
        $attributeSetRepository = $objectManager->create('\Magento\Catalog\Api\AttributeSetRepositoryInterface');
        $attributeSetRepository->deleteById($attributeSetId);

How to Export and Import Attributes and Attribute Sets in Magento

I've done this to export all attributes and their options (if it is a dropdown attribute) from the source website:

exportAttributes.php in root directory of source website:

<?php
define('MAGENTO', realpath(dirname(__FILE__)));
require_once MAGENTO . '/app/Mage.php';
Mage::app();
$entity_type_id = Mage::getModel('catalog/product')->getResource()->getTypeId();

prepareCollection($entity_type_id);

function prepareCollection($ent_type_id){
    $resource = Mage::getSingleton('core/resource');
    $connection = $resource->getConnection('core_read');
    $select_attribs = $connection->select()
            ->from(array('ea'=>$resource->getTableName('eav/attribute')))
            ->join(array('c_ea'=>$resource->getTableName('catalog/eav_attribute')), 'ea.attribute_id = c_ea.attribute_id');
            // ->join(array('e_ao'=>$resource->getTableName('eav/attribute_option'), array('option_id')), 'c_ea.attribute_id = e_ao.attribute_id')
            // ->join(array('e_aov'=>$resource->getTableName('eav/attribute_option_value'), array('value')), 'e_ao.option_id = e_aov.option_id and store_id = 0')
    $select_prod_attribs = $select_attribs->where('ea.entity_type_id = '.$ent_type_id)
                                            ->order('ea.attribute_id ASC');

    $product_attributes = $connection->fetchAll($select_prod_attribs);

    $select_attrib_option = $select_attribs
                                ->join(array('e_ao'=>$resource->getTableName('eav/attribute_option'), array('option_id')), 'c_ea.attribute_id = e_ao.attribute_id')
                                ->join(array('e_aov'=>$resource->getTableName('eav/attribute_option_value'), array('value')), 'e_ao.option_id = e_aov.option_id and store_id = 0')
                                ->order('e_ao.attribute_id ASC');

    $product_attribute_options = $connection->fetchAll($select_attrib_option);

    $attributesCollection = mergeCollections($product_attributes, $product_attribute_options);
    prepareCsv($attributesCollection);

}

function mergeCollections($product_attributes, $product_attribute_options){

    foreach($product_attributes as $key => $_prodAttrib){
        $values = array();
        $attribId = $_prodAttrib['attribute_id'];
        foreach($product_attribute_options as $pao){
            if($pao['attribute_id'] == $attribId){
                $values[] = $pao['value'];
            }
        }
        if(count($values) > 0){
            $values = implode(";", $values);
            $product_attributes[$key]['_options'] = $values;
        }
        else{
            $product_attributes[$key]['_options'] = "";
        }
        /*
            temp
        */
        $product_attributes[$key]['attribute_code'] = $product_attributes[$key]['attribute_code'];
    }

    return $product_attributes;

}

function prepareCsv($attributesCollection, $filename = "importAttrib.csv", $delimiter = '|', $enclosure = '"'){

    $f = fopen('php://memory', 'w');
    $first = true;
    foreach ($attributesCollection as $line) {
        if($first){
            $titles = array();
            foreach($line as $field => $val){
                $titles[] = $field;
            }
            fputcsv($f, $titles, $delimiter, $enclosure);
            $first = false;
        }
        fputcsv($f, $line, $delimiter, $enclosure); 
    }
    fseek($f, 0);
    header('Content-Type: application/csv');
    header('Content-Disposition: attachement; filename="'.$filename.'"');
    fpassthru($f);
}

This will give a csv file [actually i used "|" to separate ;)] paste this csv file in MAGENTO_ROOT/attribImport directory of the destination website, i.e. website to which attributes need to be imported:

now put the following code in MAGENTO_ROOT/attribImport** directory of the destination website

<?php
define('MAGENTO', realpath(dirname(__FILE__)));
require_once MAGENTO . '/../app/Mage.php';
Mage::app();
// $fileName = MAGENTO . '/var/import/importAttrib.csv';
$fileName = 'importAttrib.csv';
// getCsv($fileName);
getAttributeCsv($fileName);

function getAttributeCsv($fileName){
    // $csv = array_map("str_getcsv", file($fileName,FILE_SKIP_EMPTY_LINES));
    $file = fopen($fileName,"r");
    while(!feof($file)){
        $csv[] = fgetcsv($file, 0, '|');
    }
    $keys = array_shift($csv);
    foreach ($csv as $i=>$row) {
        $csv[$i] = array_combine($keys, $row);
    }
    foreach($csv as $row){
        $labelText = $row['frontend_label'];
        $attributeCode = $row['attribute_code'];
        if($row['_options'] != "")
            $options = explode(";", $row['_options']); // add this to createAttribute parameters and call "addAttributeValue" function.
        else
            $options = -1;
        if($row['apply_to'] != "")
            $productTypes = explode(",", $row['apply_to']);
        else
            $productTypes = -1;
        unset($row['frontend_label'], $row['attribute_code'], $row['_options'], $row['apply_to'], $row['attribute_id'], $row['entity_type_id'], $row['search_weight']);
        createAttribute($labelText, $attributeCode, $row, $productTypes, -1, $options);
    }
}

NOTE: Allthough exceptions have been handled, Backup your Database before you import these attributes, to be on safer side. Happy Importing!

Magento – Relation of attribute set with category

Attribute sets are used by other eav entities too, not just by products. So my guess is that you deleted all the attribute sets for all the eav entities (including categories).

You should restore from a backup that you made before the delete, and then either delete the attribute sets from admin, or add this condition to your query:

DELETE FROM eav_attribute_set WHERE entity_type_id = 4 AND attribute_set_id != 4;
