Carrinho web soma de 1 em 1 sem mudar quantidade

adrianac disse:

Buenos días,

Tengo un problema en mi web y es que el carrito no suma correctamente. Solo me añade de 1 en 1 por más que cambie la cantidad del input. Esto son los 2 codigos que tengo:

Inserir CODE, HTML ou PHP:

add_filter( 'woocommerce_loop_add_to_cart_link', 'quantity_inputs_for_loop_ajax_add_to_cart', 10, 2 );
function quantity_inputs_for_loop_ajax_add_to_cart( $html, $product ) {
    if ( $product && $product->is_type( 'simple' ) && $product->is_purchasable() && $product->is_in_stock() && ! $product->is_sold_individually() ) {
        // Get the necessary classes
        $class = implode( ' ', array_filter( array(
            'button',
            'product_type_' . $product->get_type(),
            $product->is_purchasable() && $product->is_in_stock() ? 'add_to_cart_button' : '',
            $product->supports( 'ajax_add_to_cart' ) ? 'ajax_add_to_cart' : '',
        ) ) );

        // Adding embeding <form> tag and the quantity field
        $html = sprintf( '%s%s<a rel="nofollow" href="%s" data-quantity="%s" data-product_id="%s" data-product_sku="%s" class="%s">%s</a>%s',
            '<form class="cart">',
            woocommerce_quantity_input( array(), $product, false ),
            esc_url( $product->add_to_cart_url() ),
            esc_attr( isset( $quantity ) ? $quantity : 1 ),
            esc_attr( $product->get_id() ),
            esc_attr( $product->get_sku() ),
            esc_attr( isset( $class ) ? $class : 'button' ),
            esc_html( $product->add_to_cart_text() ),
            '</form>'
        );
    }
    return $html;
}

add_action( 'wp_footer' , 'archives_quantity_fields_script' );
function archives_quantity_fields_script(){
    if( is_shop() || is_product_category() || is_product_tag() ): ?>
    <script type='text/javascript'>
        jQuery(function($){
            // Update quantity on 'a.button' in 'data-quantity' attribute (for ajax)
            $('form.cart').on('change', 'input.qty', function() {
                if ($(this).val() === '0')
                    $(this).val('1');
                $(this).closest('form.cart').find( 'a.add_to_cart_button').attr('data-quantity', $(this).val());
            });
        });
    </script>
    <?php endif;
}

Y este:

Inserir CODE, HTML ou PHP:

add_filter( 'woocommerce_product_add_to_cart_text', 'woo_archive_custom_cart_button_text', 10, 2 );
 
 
function quantity_inputs_for_woocommerce_loop_add_to_cart_link( $html, $product ) {
if ( $product && $product->is_type( 'simple' ) && $product->is_purchasable() && $product->is_in_stock() && ! $product->is_sold_individually() ) {
$html = '<form action="' . esc_url( $product->add_to_cart_url() ) . '" class="cart" method="post" enctype="multipart/form-data">';
$html .= woocommerce_quantity_input( array(), $product, false );
$html .= '<button type="submit" class="button alt">' . esc_html( $product->add_to_cart_text() ) . '</button>';
$html .= '</form>';
}
return $html;
}

Llevo dias buscando sin encontrar el problema. :grumpy:

   $('form.cart').on('change', 'input.qty', function() {
       var quantity = $(this).val();
       if (quantity === '' || quantity <= 0) {
           quantity = 1; // por defecto a 1 si es cero o vacío
           $(this).val(quantity);
       }
       $(this).closest('form.cart').find('a.add_to_cart_button').attr('data-quantity', quantity);
   });
