<?xml version="1.0"?><page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="2columns-left" 

xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceBlock name="page.main.title" remove="true"/>
        <referenceBlock name="catalog.compare.sidebar" remove="true"/>

        <referenceBlock name="multiple-wishlist_sidebar" remove="true" />

    </body>
</page>

    <?php echo $block->getBlockHtml('formkey')?>    <button type="submit" title="Add to Cart" class="action tocart primary">
        <span><?php echo __('Order Now'); ?></span>
    </button>
</form>

How to add a ContactUs Form

Magento includes contact form functionality by default. A link to a contact form can usually be found in the footer of your Magento installation.

Of course, you can add a contact form on any page. All you need to do is:

• Log in to the administrator area.
• Go to CMS > Pages.
• Select the page you want to edit or create a new page.

Paste the following code using the HTML option of the WYSIWYG editor:

<!– CONTACT FORM CODE BEGIN–>{{block type='core/template' name='contactForm' template='contacts/form.phtml'}}<!– CONTACT FORM CODE END–>

Save the changes and the contact form will appear on the desired page.

<?php
require_once 'Mage/Review/controllers/ProductController.php';

        $allowedKeys = array_fill_keys(array('detail', 'title', 'nickname','email'), true);

        foreach ($reviewData as $key => $value) {
            if (isset($allowedKeys[$key])) {
                $croppedValues[$key] = $value;

        return $croppedValues;

Set Sorting Direction / Order for a specifi Category when FPC is enabled

As we know, sorting option of a category is persistent on different categories. Which means if you select sorting option as "Price" for a Category 1 and go to Category 2 sorting option will be selected as "Price" though default sorting is selected as "Best Value".


Scenario:
Suppose there is a category as "New" and default category for "New" is "Product New from Date (news_from_date)" attribute.

When ever customer comes to New category, default sorting option should be selected as "New" (news_from_date), which means Sorting persistence should not affect New Category.

Step (1):
- Go to BO => Catalog => Categories => Manage Categories => Select Category "Niw"
- Under Display Settings Tab
---- Default Product Listing Sort By = "Set Product as New from Date"
- Under Custom Design Tab
---- Custom Layout Update:
 <reference name="product_list_toolbar">
  <action method="setDefaultDirection"><string>desc</string></action>
</reference>

Set Sorting Direction / Order for a specifi Category when FPC is enabled

As we know, sorting option of a category is persistent on different categories. Which means if you select sorting option as "Price" for a Category 1 and go to Category 2 sorting option will be selected as "Price" though default sorting is selected as "Best Value".


Scenario:
Suppose there is a category as "New" and default category for "New" is "Product New from Date (news_from_date)" attribute.

When ever customer comes to New category, default sorting option should be selected as "New" (news_from_date), which means Sorting persistence should not affect New Category.

Step (1):
- Go to BO => Catalog => Categories => Manage Categories => Select Category "Niw"
- Under Display Settings Tab
---- Default Product Listing Sort By = "Set Product as New from Date"
- Under Custom Design Tab
---- Custom Layout Update:
 <reference name="product_list_toolbar">
  <action method="setDefaultDirection"><string>desc</string></action>
</reference>
