Magento2 : Custom Category Attribute value Not Saving?

Question

I've create a module to add a custom attribute to my categories, however my code doesn't seem to be creating the attribute in my eav_attribute table, the field shows on my category pages but it doesn't save the values?

Can anyone advise why this isn't working.

Answer 2

Magento 2 change custom category attribute value

---

<?php
//increase the max execution time
@ini_set('max_execution_time', -1);
//memory_limit
@ini_set('memory_limit', -1);

error_reporting(E_ALL);
ini_set('display_errors', '1');

use \Magento\Framework\App\Bootstrap;

include('app/bootstrap.php');

$bootstrap = Bootstrap::create(BP, $_SERVER);

$objectManager =  \Magento\Framework\App\ObjectManager::getInstance();        

$appState = $objectManager->get('\Magento\Framework\App\State');

$appState->setAreaCode('frontend');

$categoryCollection = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Category\CollectionFactory');

$categories = $categoryCollection->create();

$categories->addAttributeToSelect('*');

$categories->load();

if (count($categories) > 0):

        foreach($categories as $category):

            $catId = $category->getId();

                $category = $objectManager->create('Magento\Catalog\Model\CategoryFactory')->create()->setStoreId(0)->load($catId);
                $CategoryName = $category->getName();

                $metaTitle = "Buy ".$CategoryName." from My Site";

                $category->setMetaTitle($metaTitle);

                $category->save();


        endforeach;
     else: echo "No Results";
    endif;

?>

Answer 3

Answer is little different for me.

Re-run installation of eavSetup because adding attribute was failing

Answer 4

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$category = $objectManager->create('Magento\Catalog\Model\CategoryFactory')->create()->load($categoryId);    
$category->setCustomAttribute("test");
$category->getResource()->saveAttribute($category, 'custom_attribute');
