How to migrate Customers from Magento2 to WordPress?

Lets break it into 2 parts:

a. Migrate Customer data
b. Migrate Customer Passwords

1) Migrate Customer Data from Magento2 to WordPress

This is rather easy to be honest, there are several plugins for importing data from CSV and then mapping the CSV fields.

My recommended plugin is Customer/Order/Coupon CSV Import Suite by SkyVerge

It basically does everything from customer email to customer address data. It also provides column mapping and custom attribute import for all users. Also comes with multiple configuration options.

Best Free Alternative is https://wordpress.org/plugins/import-users-from-csv-with-meta
But in this one, you can not import magento2 passwords as of v 1.15.0.1
I will update about the solution very soon. So as of now only paid option is there.

2) Migrate Customer Password from Magento2 to WordPress

This wordpress plugin checks and updates passwords of users migrated from Magento2 to WordPress
Plugin Link: https://github.com/harshvardhanmalpani/migrate-password-from-magento2-to-wordpress

Requirements:

  1. user_pass column will have this kind data from Magento2 dcbdc524f215fd054502dcad5a23a702ec029c02ff8d7051d049f76e29927f8b:C8yVqeuPfkHWvkmipx0iKLPtOUGETpLL:1
  2. usermeta table must have a meta_key “migrated_cs” for this user, meta_value can be anything positive
  3. This plugin file password-migrator.php should be in wp-content/plugins and must be an active plugin

What is does?

For new wordpress based users which dont have anything to do with magento2, it doesnt do anything

For all migrated users (those have the key “migrated_cs”), this plugin checks if input password matches old password from magento2 or not, if matched, it clears the key migrated_cs and updates the password using wordpress’ algorithm ; else results false.

How to change attribute dropdown type to multi-select in Magento 2?

Short Answer:

Not possible via Magento2 Admin Backend.

Solution:

You need to update eav_attribute table and edit information about backend_source, frontend_input etc.

Simple query for that is:

UPDATE `eav_attribute` SET `backend_model`="Magento\\Eav\\Model\\Entity\\Attribute\\Backend\\ArrayBackend", `backend_type`="varchar", `frontend_input`="multiselect", `source_model`=NULL WHERE `attribute_id`=YOUR_ATTRIBUTE_ID_INTEGER LIMIT 1

Replace YOUR_ATTRIBUTE_ID_INTEGER with your attribute_id like 355

How to disable products in Magento2 which dont have any gallery image?

UPDATE `catalog_product_entity_int` SET `value`=2 where `entity_id` in (SELECT a.`entity_id` FROM `catalog_product_entity` AS a LEFT JOIN `catalog_product_entity_media_gallery_value` AS b ON a.entity_id = b.entity_id LEFT JOIN `catalog_product_entity_media_gallery` AS c ON b.value_id = c.value_id WHERE c.value IS NULL) and `attribute_id` = 96

It is SQL query

Assumption:

value=2 means disable and value=1 means enable

attribute_id=96 means “status” attribute

How to remove sign in popup from Magento 2 checkout page?

Magento2 has this authentication pop up on checkout page, which many store owners wont like to see on their checkout page.

Background of this pop up area and Related files

The pop up itself is generated by Magento_Customer::account/authentication-popup.phtml

But this pop up works very differently on checkout page. In fact this is a separate pop up than the one you see in header area. It is embedded in a series of js files which are governed by knockout-js

Other file responsible is: vendor/magento/module-checkout/view/frontend/web/js/proceed-to-checkout.js

Here is how to remove it finally

Edit file or overload the file

app/design/frontend/YourVendor/YourTheme/Magento_Checkout/web/template/onepage.html

delete the following lines and save the file

<!-- ko foreach: getRegion('authentication') -->
<!-- ko template: getTemplate() --><!-- /ko -->
<!--/ko-->

How to show correct item count in Magento 2 Checkout Order summary?

By default, app/design/Magento/Checkout/view/frontend/web/template/summary/cart-items.html file is being used
Or vendor/magento/module-checkout/view/frontend/web/template/summary/cart-items.html

To overload this file, create file cart-items.html in your theme folder. Make sure you place the file in Magento_Checkout/web/template/summary/

Edit the line

<span data-bind="text: getCartLineItemsCount()"></span>

And replace it with

<span data-bind="text: getItemsQty()"></span>

vendor/magento/module-checkout/view/frontend/web/js/view/summary/cart-items.js

How to dump all options for any attribute in Magento 2 programmatically?

The following code does not adhere to Magento’s developer recommendations. Using object manager in such a way externally is a TERRIBLE idea.

Comment out line number 2 and then run the script. Edit line 11 and put the attribute code you want to dump

<?php
header("Location: /");exit;
use \Magento\Framework\App\Bootstrap;
error_reporting(E_ALL);
ini_set("display_errors", 1);
include('./app/bootstrap.php');
$bootstrap     = Bootstrap::create(BP, $_SERVER);
$objectManager = $bootstrap->getObjectManager();

$eavConfig = $objectManager->get('\Magento\Eav\Model\Config');
$attribute = $eavConfig->getAttribute('catalog_product', 'manufacturer');
$options   = $attribute->getSource()->getAllOptions();
$options   = array_slice($options, 1);
usort($options, function($a, $b)
{
    return strcasecmp($a['label'], $b['label']);
});
if (count($options))
    $v = "<table>";
foreach ($options as $option) {
    $v .= "<tr><td>" . $option['value'] . '</td><td>' . $option['label'] . '</td></tr>';
}
if (count($options))
    $v .= "</table>";
echo $v;
?>
   <style>
    table tr:nth-child(odd){background:#444;color:#fff}
