I used Magento 2 add Sort By Best Sellers Option on category products litsing page and Magento 2 Sort by New Products and Most View Product for sorting options. now I want to add price (high to low) and remove name (default option) and direction switcher. Could anyone help me please?

here is my code :

CompanyModuleModelConfig

class Config extends MagentoCatalogModelConfig

{

    public function getAttributeUsedForSortByArray()

    {

       $options = ['mostviewed' => __('Most Viewed'), 'newest' => __('Newest'), 'bestseller' => __('Best Seller'), 'price' => __('Price - Low To Highا');

        foreach ($this->getAttributesUsedForSortBy() as $attribute) {

            /* @var $attribute MagentoEavModelEntityAttributeAbstractAttribute */

            $options[$attribute->getAttributeCode()] = $attribute->getStoreLabel();

        }



       return $options;

    }

}

CompanyModuleBlockProductProductListToolbar

class Toolbar extends MagentoCatalogBlockProductProductListToolbar

    {

        public function setCollection($collection)

        {

            if($this->getCurrentOrder()=="bestseller")

            {

                  $collection->getSelect()->joinLeft( 

                    'sales_order_item', 

                    'e.entity_id = sales_order_item.product_id', 

                    array('qty_ordered'=>'SUM(sales_order_item.qty_ordered)')) 

                    ->group('e.entity_id') 

                    ->order('qty_ordered '.$this->getCurrentDirectionReverse());

            }

            if($this->getCurrentOrder() == "newest")

            {

                $collection->getSelect()

                    ->order('created_at ' . $this->getCurrentDirectionReverse());

            }

            if($this->getCurrentOrder() == "mostviewed")

            {

                $collection->getSelect()->joinLeft(

                    'report_event',

                    'e.entity_id = report_event.object_id',

                    array('view_count' => 'COUNT(report_event.event_id)'))

                    ->group('e.entity_id')

                    ->order('view_count ' . $this->getCurrentDirectionReverse());

            }



            $this->_collection = $collection;



            $this->_collection->setCurPage($this->getCurrentPage());



            $limit = (int)$this->getLimit();

            if ($limit) {

                $this->_collection->setPageSize($limit);

            }

            if ($this->getCurrentOrder()) {

                $this->_collection->setOrder($this->getCurrentOrder(), $this->getCurrentDirection());

            }

            return $this;

        }



        public function getCurrentDirectionReverse() {

                if ($this->getCurrentDirection() == 'asc') {

                    return 'desc';

                } elseif ($this->getCurrentDirection() == 'desc') {

                    return 'asc';

                } else {

                    return $this->getCurrentDirection();

                }

            }



    }

For price high to low, add a condition like this in your CompanyModuleBlockProductProductListToolbar file and setCollection function:

if($this->getCurrentOrder()=="high_to_low"){

{

    $this->_collection->setOrder('price', 'desc');

}

if($this->getCurrentOrder()=="low_to_high"){

    {

        $this->_collection->setOrder('price', 'asc');

    }

and you should have a plugin to override config and it should look like this:

CompanyModulePluginCatalogModel

<?php

namespace CompanyModulePluginCatalogModel;



class Config

{

    public function afterGetAttributeUsedForSortByArray(

    MagentoCatalogModelConfig $catalogConfig,

    $options

    ) {

        //Remove specific default sorting options(if require)

        unset($options['position']);

        unset($options['name']);

        unset($options['price']);



        //New sorting options

        $newOption['mostviewed'] = __('Most Viewed');

        $newOption['newest'] = __('Newest');

        $newOption['bestseller'] = __('Best Seller');

        $newOption['high_to_low'] = __('Price - High To Low');

        $newOption['low_to_high'] = __('Price - Low To High');



        //Merge default sorting options with new options

        $options = array_merge($newOption, $options);



        return $options;

    }



}

Since we have a plugin, we need to add it in the di.xml file like this under etc/di.xml

<?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="MagentoCatalogBlockProductProductListToolbar" type="CompanyModuleBlockProductProductListToolbar" />    

    <type name="MagentoCatalogModelConfig">

        <plugin name="Company_CustomSorting_model_config" type="CompanyModulePluginCatalogModelConfig" />

    </type>

</config>

To remove the direction switcher, you can remove it using CSS/jQuery that should be simple to select the div element and add display none class in css or add remove jquery function.

I hope this helps.
