Woocommerce：为ajax请求添加自定义字段

问题描述 投票：0回答：1

我有一个问题，我自己无法解决。

我使用自定义输入字段为客户输入个人文本。如果我不使用Ajax请求它是完美的，但不是。

这是自定义输入字段代码

    /*
 * Display input on single product page
 * @return html
 */
function olikdesign_Wunschtext(){
    global $post;
    $terms = wp_get_post_terms( $post->ID, 'product_cat' );
    foreach ( $terms as $term ) $categories[] = $term->slug;
    $woocommerce;
    $value = isset( $_POST['_Wunschtext'] ) ? sanitize_text_field( $_POST['_Wunschtext'] ) : '';


// Wunschtext Textfeld anzeigen, sofern der Artikel sich in der Kategorie Custom befindet.

    if ( in_array( 'individuell', $categories ) ) {
         printf( '<div class="variations wunschtext"><label for="wunschtext">%s</label><input type="text" id="wunschtext" name="wunschtext" class="input-text-custom_text" maxlength="25" data-attribute_name="attribute_wunschtext" value="%s" /><small class="custom_text_description">Schreibe hier deinen Wunschtext hinein &mdash; Max. 25 Zeichen.</small>




         </div>', __( 'Wunschtext', 'olikdesign-plugin-textdomain' ), esc_attr( $value ) );
    } else {
         //Nichts anzeigen
    }

所以现在我想将此字段添加到我的ajax请求中，但我无法解决它。

这是我的ajax代码：

jQuery( function( $ ) {

    $(".single_add_to_cart_button").addClass("ajax_add_to_cart");

    $( ".post-type-archive-product" ).on( "click", ".quantity input", function() {
        return false;
        });

        $( ".archive" ).on( "change input", ".quantity .qty", function() {
            var add_to_cart_button = $( this ).parents( ".product" ).find( ".add_to_cart_button" );
            // For AJAX add-to-cart actions
            add_to_cart_button.data( "quantity", $( this ).val() );
            // For non-AJAX add-to-cart actions
            add_to_cart_button.attr( "href", "?add-to-cart=" + add_to_cart_button.attr( "data-product_id" ) + "&quantity=" + $( this ).val() );
                        $( '#mini-cart, .mini-cart-inner' ).addClass('active').fadeIn(1000);
                        $("body").addClass("overflow-hidden");
        });

        $(".input-text.qty.text").bind('keyup mouseup', function () {
            var value = $(this).val();
        $(".product_quantity").val(value)
        });

        if ( typeof wc_add_to_cart_params === 'undefined' )
            return false;

                }
                if ( !variations.length) {
                    variations = $variation_form.find( 'input[name^=attribute]' );
                }


            variations.each( function() {
                var $this = $( this ),
                    attributeName = $this.attr( 'name' ),

                    attributeTaxName = attributeName.substring( index + 1 );
                    $this
                        .addClass( 'required error' )

                        }
                        $( '.widget_shopping_cart, .updating' ).stop( true ).css( 'opacity', '1' ).unblock();
                        $( '.shop_table.cart' ).load( this_page + ' .shop_table.cart:eq(0) &gt; *', function() {
                        $( '.shop_table.cart' ).stop( true ).css( 'opacity', '1' ).unblock();
                        $( document.body ).trigger( 'cart_page_refreshed' );
                        });
                        $( '.cart_totals' ).load( this_page + ' .cart_totals:eq(0) &gt; *', function() {
                        $( '.cart_totals' ).stop( true ).css( 'opacity', '1' ).unblock();
                    });
                    }
                });
                return false;
            } else {
                return true;
            }
        });
    });

我认为它可以很容易解决但我无法看到解决方案。我认为这个“$ cart_item ['Wunschtext']”必须保存到我的ajax作为价值，但如何？

此外，如果未输入输入，我想获取错误消息。

我希望有一个人可以帮助我。

非常爱<3你的时间。

添加了一些代码，但它没有保存值：

我的功能：

    function olikdesign_ajax_add_to_cart_woo_callback() {

//在ob_start（）之后;

    $wunschtext = $_POST['_wunschtext']; // Wunschtext


  error_log("Variation Product", 0);
  $passed_validation = apply_filters( 'woocommerce_add_to_cart_validation', true, $product_id, $quantity, $wunschtext);

  if ( $passed_validation && WC()->cart->add_to_cart( $product_id, $quantity, $variation_id, $variation, $wunschtext  ) ) {
    do_action( 'woocommerce_ajax_added_to_cart', $product_id );
    if ( get_option( 'woocommerce_cart_redirect_after_add' ) == 'yes' ) {
      wc_add_to_cart_message( $product_id );
    }

    // Return fragments
    WC_AJAX::get_refreshed_fragments();
  }

进入我的Ajax我补充说

var wunschtext = $variation_form.find( 'input[name=_wunschtext]' ).val(); //Wunschtext

和

 var data = {
                            action: 'olikdesign_ajax_add_to_cart_woo',
                            product_id: product_id,
                            quantity: quantity,
                            variation_id: var_id,
                            variation: item,
                            wunschtext: wunschtext  // Wunschtext
                            };

我发现这个问题已经存在，但无法弄清楚我需要添加underdash（_）的位置。 Same issue here

希望你能理解我。
