通过PHP或jQuery刷新cart_fragments（迷你购物车）？

Im trying to update the mini-cart (cart_fragments) after/on an ajax event. It works like this.

我试图在/ ajax事件之后更新迷你购物车（cart_fragments）。它的工作原理如下。

HTML Trigger:

HTML触发器：

<a id="woomps-button-\'.$nr.\'" class="woomps-button" '.$ajax_url.' data-button-nr="'.$nr.'">

jQuery request:

jQuery请求：

jQuery( document ).on('click', '.woomps-button', function() {
    var nr= jQuery(this).data('button-nr');
    jQuery.ajax({
        url : subpost.ajax_url,
        type : 'post',
        data : {
            action : 'woomps_update_nr',
            security : subpost.security,
            nr: nr
        },
        success : function( response ) {
            window.alert(nr);
            //MAYBE_code to refresh_fragments here
            }
    });
    return false;
});

PHP responder:

PHP响应者：

function woomps_update_choosen_person () {
    $p = $_POST['nr'];
    if ($p == 1) {$x= "This must show in cart";}
    WC()->session->set( 'woomps_limit_by_persons' , $x );

    //MAYBE code to refresh_fragments here
}

And in the mini-cart.php template i have a calculation based on this field.

在mini-cart.php模板中，我有一个基于此字段的计算。

$items_left_start = WC()->session->get( 'woomps_limit_by_persons' )?: 3 ;
//Do something something here

So this works, except I need to refresh the cart like when an item is added to cart. My assumption is that is should be an ajax request from jQuery that i can put in the success block?

所以这是有效的，除了我需要刷新购物车，就像物品被添加到购物车。我的假设是应该是来自jQuery的ajax请求，我可以放入成功块？

The class i (think) I want to fire is this WC_AJAX::get_refreshed_fragments(); But this is fired from an an add_action, so i tried this add_action( 'wp_ajax_nopriv_woocommerce_get_refreshed_fragments', array( 'WC_AJAX', 'get_refreshed_fragments' ) );. But it did not work either.

我想要解雇的类是这个WC_AJAX :: get_refreshed_fragments（）;但这是从一个add_action发出的，所以我尝试了这个add_action（'wp_ajax_nopriv_woocommerce_get_refreshed_fragments'，数组（'WC_AJAX'，'get_refreshed_fragments'））;.但它也没有用。

I also try to create an jQuery ajax call like it does in the add_to_cart button, but it neither worked.

我也尝试像在add_to_cart按钮中那样创建一个jQuery ajax调用，但它既不起作用。

//MAYBE_code to refresh_fragments here
        var data = {};
        jQuery.post(
            wc_get_refreshed_fragments_params.wc_ajax_url.toString().
            replace( '%%endpoint%%', 'get_refreshed_fragments' ), data,
            function( response ){

            })

        }

I do not completely understand how this works, if anyone have some pointers or a snippet i would so much appriciate it. Been struggeling with this for some time now.

我不完全理解这是如何工作的，如果有人有一些指针或片段我会非常喜欢它。已经有一段时间了。

After much struggeling this topic on stack helped create the correct code to update mini cart fragments. It was both PHP and jQuery neeeded.

经过多次讨论，这个主题在堆栈上帮助创建了更新迷你购物车碎片的正确代码。这是PHP和jQuery都需要的。

So basically you can call the WC_AJAX::get_refreshed_fragments() at the end of your PHP coode responder; if it comes from an AJAX call. It will not return to your PHP responder code so put it at the end. The PHP respons will end/sent back to jQuery inside the WC_AJAX::get_refreshed_fragments(); so you also need to create some jQuery that responds to this. This i got from the topic:

所以基本上你可以在PHP coode响应器的末尾调用WC_AJAX :: get_refreshed_fragments（）;如果它来自AJAX调用。它不会返回到你的PHP响应器代码，所以把它放在最后。 PHP响应将在WC_AJAX :: get_refreshed_fragments（）内结束/发送回jQuery;所以你还需要创建一些响应这个的jQuery。这是我从主题：

 var fragments = response.fragments;

 if ( fragments ) {

                jQuery.each(fragments, function(key, value) {
                    jQuery(key).replaceWith(value);
                });

            }
