    /**

 */
function custom_woo_before_shop_link()
{
    add_filter('woocommerce_loop_add_to_cart_link', 'custom_woo_loop_add_to_cart_link', 10, 2);
    add_action('woocommerce_after_shop_loop', 'custom_woo_after_shop_loop');
}
add_action('woocommerce_before_shop_loop', 'custom_woo_before_shop_link');
/**
 * customise Add to Cart link/button for product loop
 * @param string $button
 * @param object $product
 * @return string
 */
function custom_woo_loop_add_to_cart_link($button, $product)
{
    // not for variable, grouped or external products
    if (!in_array($product->product_type, array(
        'variable',
        'grouped',
        'external'
    ))) {
        // only if can be purchased
        if ($product->is_purchasable()) {
            // show qty +/- with button
            ob_start();
            woocommerce_simple_add_to_cart();
            $button      = ob_get_clean();
            // modify button so that AJAX add-to-cart script finds it
            $replacement = sprintf('data-product_id="%d" data-quantity="1" $1 add_to_cart_button product_type_simple ', $product->id);
            $button      = preg_replace('/(class="single_add_to_cart_button)/', $replacement, $button);
        }
    }
    return $button;
}
/**
 * add the required JavaScript
 */
function custom_woo_after_shop_loop()
{
?>

    <script>
    jQuery(function($) {

    <?php
    /* when product quantity changes, update quantity attribute on add-to-cart button */
?>
    $("form.cart").on("change", "input.qty", function() {
        $(this.form).find("button[data-quantity]").attr("data-quantity", this.value);
    });

    <?php
    /* remove old "view cart" text, only need latest one thanks! */
?>
    $(document.body).on("adding_to_cart", function() {
        $("a.added_to_cart").remove();
    });

    });
    </script>

    <?php
}

Another way tried.

bellow code added in index.php but can not add quantity field manually . any idea how

<?php
          $args = array( 
                'post_type' => 'product', 
                'stock' => 1, 
                'posts_per_page' => 16, 
                'orderby' =>'date',
                'order' => 'DESC' );

          $loop = new WP_Query( $args );
          while ( $loop->have_posts() ) : $loop->the_post(); global $product; ?>

                  <div class="span3">    
                    <a id="id-<?php the_id(); ?>" href="<?php the_permalink(); ?>" title="<?php the_title(); ?>">
                      <?php if (has_post_thumbnail( $loop->post->ID )) echo get_the_post_thumbnail($loop->post->ID, 'shop_catalog'); else echo '<img src="'.woocommerce_placeholder_img_src().'" alt="My Image Placeholder" width="65px" height="115px" />'; ?>

                          <h3><?php the_title(); ?></h3>
                          <span class="price"><?php echo $product->get_price_html(); ?></span>

                     </a>

                      <?php woocommerce_template_loop_add_to_cart( $loop->post, $product ); ?>
                  </div><!-- /span3 -->
      <?php endwhile; ?>
      <?php wp_reset_query(); ?>

Tried also WooCommerce Thumbnail Input Quantities plugins too. it added quantity field everywhere but not work.

Guys any idea how can solve my thing.

Thanks
