我有一个问题，我自己无法解决。
我使用自定义输入字段供客户输入个人文本。如果我不使用Ajax请求，那么它可以运行，但是不能。
这是“自定义”输入字段代码

global $post;
$terms = wp_get_post_terms( $post->ID, 'product_cat' );

$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 — Max. 25 Zeichen.</small>

所以现在我想将此字段添加到我的ajax请求中，但是我无法解决它。
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();

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

}

}
$( '.widget_shopping_cart, .updating' ).stop( true ).css( 'opacity', '1' ).unblock();
$( '.shop_table.cart' ).load( this_page + ' .shop_table.cart:eq(0) > *', function() {

我认为可以很轻松地解决它，但我看不到解决方案。我认为这个“ $ cart_item ['Wunschtext']”必须作为值保存到我的ajax中，但是怎么办？
如果没有输入输入，我也想使错误消息起作用。
我希望有人能帮助我。
在您的时间里，有很多爱<3。
答案 0 :(得分：0)
添加了一些代码，但未保存值：
对我的职能：
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();
}
添加到我添加的Ajax中
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
};
我发现此问题已存在，但无法弄清楚我需要在何处添加下划线（_）。 Same issue here
希望你能理解我。
