If you want to change the main price with a custom price attribute. You can use the below method

1. Create file di.xml on app/code/Magemonkeys/CustomPrice/etc/frontend

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="MagentoCatalogModelProduct">
        <plugin name="change_product" type="MagemonkeysCustomPricePluginModelProduct" sortOrder="1" />
    </type>
</config>

2. Create file Product.php on app/code/Magemonkeys/CustomPrice/Plugin/Model

<?php
namespace MagemonkeysCustomPricePluginModel;
 
class Product
{
    public function afterGetPrice(MagentoCatalogModelProduct $subject, $result)
    {        
        $result = $subject->getCustomPrice(); // you can set custom attribute price
        return $result;
    }
}

We can create custom api for GraphQL.

As per the app/code/ standard, our module name is Magemonkeys/Customgraphql

We can create schema.graphqls file in module etc folder.

Below is the code for that file.

type Query
{
    CustomGraphql (
        username: String @doc(description: "Email of the customer")
        password: String @doc(description: "Password")
        fieldtype: String @doc(description: "Field Type")
    ): CustomGraphqlOutput @resolver(class: "Magemonkeys\Customgraphql\Model\Resolver\ResolverGraphql") @doc(description:"Customgraphql Datapassing")
}
type CustomGraphqlOutput
{
    username: String
    password: String
    fieldtype: String
}

After that we need to create Model Resolver file.

Create file ResolverGraphql.php in this location of module
Magemonkeys/Customgraphql/Model/Resolver/

Below is the code for that file.

<?php
namespace MagemonkeysCustomgraphqlModelResolver;

use MagentoFrameworkGraphQlConfigElementField;
use MagentoFrameworkGraphQlExceptionGraphQlInputException;
use MagentoFrameworkGraphQlQueryResolverInterface;
use MagentoFrameworkGraphQlSchemaTypeResolveInfo;
use MagentoFrameworkExceptionNoSuchEntityException;
use MagentoFrameworkGraphQlExceptionGraphQlNoSuchEntityException;

class ResolverGraphql implements ResolverInterface
{
    public function resolve(
        Field $field,
        $context,
        ResolveInfo $info,
        array $value = null,
        array $args = null)
    {
        if (!isset($args['username']) || !isset($args['password']) || !isset($args['fieldtype'])||
            empty($args['username']) || empty($args['password']) || empty($args['fieldtype']))
        {
            throw new GraphQlInputException(__('Invalid arguments list please check.'));
        }
        $output = [];
        $output['username'] = $args['username'];
        $output['password'] = $args['password'];
        $output['fieldtype'] = $args['fieldtype'];
      
        return $output ;
    }
}

After that you can check API in Postman API tool.

That’s it.

By using GraphQL, You can get data of logged in customers.

Magento 2 can directly call api to get data by resolver.

Module name : Magemonkeys::Custom

create file schema.graphqls in etc folder in that module

type Query
{
    getCustomerData: Response 
    @resolver(class:"Magemonkeys\Custom\Model\Resolver\Getdataforcustomer")
}

type Response
{
    customer_id: String
    customer_name: String
}

Create Getdataforcustomer.php in Model/Resolver Folder in that module

namespace MagemonkeysCustomModelResolver;

use MagentoFrameworkGraphQlQueryResolverInterface;
use MagentoFrameworkGraphQlConfigElementField;
use MagentoFrameworkGraphQlSchemaTypeResolveInfo;
use MagentoFrameworkGraphQlExceptionGraphQlNoSuchEntityException;
use MagentoFrameworkGraphQlExceptionGraphQlAuthorizationException;
use MagentoCustomerGraphQlModelCustomerGetCustomer;

class Getdataforcustomer implements ResolverInterface
{
   private $getdataforCustomer;
     
   public function __construct(GetCustomer $getdataforCustomer)
   {
      $this->getCustomer = $getdataforCustomer;
   }
   public function resolve(Field $field, $context, ResolveInfo $info, array $value = null, array $args = null)
   {
      try
      {
         if (false === $context->getExtensionAttributes()->getIsCustomer())
         {
            throw new GraphQlAuthorizationException(__('The current customer not getting'));
         }
         $customerdata = $this->getCustomer->execute($context);
         $customername = $customerdata->getFirstName()." ".$customerdata->getLastName();
         $result = ['customer_id' => $customer->getId(),
                    'customer_name' => $customername
                   ];   
         return $result;
      }
      catch(Exception $exception)
      {
          throw new GraphQlNoSuchEntityException(__($exception->getMessage()));
      }
   }
}

After that run command to call api url

That’s it.

If you need some specific shipping title change, then use the below method

For Ex. Priority Mail 1-Day instead of Priority Mail (2-3 Days)

Firstly, you need to add the following file.

1. Create file di.xml on app/code/Magemonkeys/UspsShipping/etc

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
   <preference for="MagentoQuoteModelQuoteAddressRateResultMethod" type="MagemonkeysUspsShippingPluginModelQuoteAddressRateResultMethod" />
</config>

2. Create file Method.php on app/code/Magemonkeys/UspsShipping/Plugin/Model/Quote/Address/RateResult

<?php
namespace MagemonkeysUspsShippingPluginModelQuoteAddressRateResult;

class Method extends MagentoQuoteModelQuoteAddressRateResultMethod
{
    public function setPrice($price)
    {
        if (strpos($this->getMethodTitle(), "Priority Mail 1-Day") !== false) {
            $this->setMethodTitle("Priority Mail (2-3 Days)");
        }
        $this->setData('price', $this->priceCurrency->round($price));
        return $this;
    }

} ?>

This bug is available on default Magento 2.4.3

To solve it, go to,

vendormagentomodule-directoryModelCurrency.php

And comment the code under the formatTxt function:

if ($this->canUseNumberFormatter($options)) {
    return $this->formatCurrency($price, $options);
}

Layered navigation Filterable (with results):

– This attribute will be shown only if there are products matching any of its attributes-options value.
– filter is shown on the category page Layered Navigation. However only options values, where products are available will be listed for the filter.
– In this case, products list filtration works if selected filters change from currently shown options.

Layered navigation Filterable (no results):

– In this case, All attribute options will be shown even if there won’t be any products matching or associated with them.
– filter is shown on the category page Layered Navigation. if the filter is set to ‘no results’, it will list all options, even no products are associated with specific options.
– If any attribute options not Associated with any products then its show Zero counts. Ex: Color Attribute with options Red (0).

For more understanding, you can check these options from admin and check the difference in the front end to get a better idea.

Thanks!

If you face pagination not working issue after upgrading Magento 2.4.3 then follow below few steps.

Step 1 : Open your theme’s list.phtml file like app/design/frontend/Magemonkeys/CustomTheme/Magento_Catalog/templates/product/list.phtml

Step 2 : Find below code in the bottom section of the list.phtml file

<?= $block->getToolbarHtml() ?>

Step 3 : Replace above code with below code in the bottom section of the list.phtml file

<?= $block->getChildBlock('toolbar')->setIsBottom(true)->toHtml() ?>

Step 4 : After place above code, please run below mentioned commands

php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy
php bin/magento cache:clean

That’s it.

Now when you will refresh the category page, you will find pagination on working condition.
