Jadikan Pagoda AJAX berfungsi dengan (AJAX) parameter filter URL saat refresh

Saya memiliki filter AJAX yang terdefinisi dengan baik, dalam dua bagian, satu untuk memuat lebih banyak tombol, dan satu untuk pilihan filter drop down. Keduanya memuat ulang daftar properti di front-end di AJAX, dan bekerja bersama secara bersamaan (mis. Jika saya memilih harga Min, harga maks dan jumlah tempat tidur dalam dropdown, daftar menyegarkan, dan memuat lebih banyak tombol berfungsi sebagaimana mestinya) .

Filter yang sama juga berfungsi dengan parameter URL. Jadi misalnya, jika URL-nya:

mydomain.com/?min_price=100000&max_price=5000000&beds=3&page=3

Itu akan menyaring oleh parameter tersebut. Itu bahkan menunjukkan 3 halaman senilai properti sebagaimana mestinya. Ini bekerja dengan baik, termasuk pada beban awal. Namun, itu tidak berfungsi dengan pagination, JIKA URL dimuat secara langsung. Jika saya memasukkan URL di atas secara langsung ke browser, dan memuat, hasil awal sudah benar, tetapi saat mengklik tombol Load More, itu mengubah halaman = 3 ke halaman = 4 (benar) tetapi menambahkan halaman kedua dari properti selesai tanpa filter. , dan terus melakukannya - daripada menjalankan pagination yang disaring.

Apa yang saya lakukan salah?

Ini kode saya (maaf itu banyak!)

JS:

jQuery(function($){


 // AJAX Stuff for filters + load more button

/*

$('#prop_loadmore').click(function(){

    $.ajax({
        url : prop_loadmore_params.ajaxurl,

Blok kode ini dieksekusi ketika #prop_loadmorediklik:

var params = new URLSearchParams(location.search);
params.set('page', prop_loadmore_params.current_page);
window.history.replaceState({}, "", decodeURIComponent(`${location.pathname}?${params}`));

Anda menggunakan prop_loadmore_paramskenaikan halaman mana saat ini ketika tombol diklik, tetapi tampaknya tidak memiliki referensiprice_min atauprice_max

Anda harus menyesuaikan $('#prop_loadmore').click(function(){...})untuk memasukkan sesuatu seperti:

var params = new URLSearchParams(location.search);

params.set('page', prop_loadmore_params.current_page);

//Add All Additional Parameters in this way
if (prop_loadmore_params.price_min){
     params.set('price_min', prop_loadmore_params.price_min);
}
if (prop_loadmore_params.price_max){
     params.set('price_max', prop_loadmore_params.price_max);
}
// ...

window.history.replaceState({}, "", decodeURIComponent(`${location.pathname}?${params}`));

Dan kemudian $('#filter').change(function(){})pastikan Anda menambahkan nilai yang difilter keprop_loadmore_params objek.

Biarkan saya tahu bagaimana kelanjutannya!

Anda mengirim POST dengan AJAX tetapi Anda memeriksa dalam PHP dengan $ _GET ['halaman']

if (!empty($_GET['page'])) {
    $the_page = $_GET['page'];
}

Anda dapat menggunakan $ _REQUEST

Pada akhirnya, saya memecahkan ini sendiri. Cara saya melakukannya adalah dengan mengirimkan parameter URL ke variabel sebelum loadmore AJAX dijalankan, sesuatu di sepanjang baris ini

var url_string = window.location;
var price_min = (new URL(url_string)).searchParams.get("price_min");
var price_max = (new URL(url_string)).searchParams.get("price_max");
var bedrooms = (new URL(url_string)).searchParams.get("beds");
var property_type = (new URL(url_string)).searchParams.get("type");
var sort_by = (new URL(url_string)).searchParams.get("sort_by");
var the_page = (new URL(url_string)).searchParams.get("page");

Ini kemudian membuat REQUEST bekerja pada panggilan ajax dengan mengklik tombol load more
