Tengo un filtro AJAX bien definido, en dos partes, una para cargar más botón y otra para una selección de filtros desplegables. Ambos recargan una lista de propiedades en el front-end en AJAX y trabajan juntos al unísono (por ejemplo, si selecciono Precio mínimo, Precio máximo y número de camas en los menús desplegables, la lista se actualiza y el botón Cargar más funciona como debería) .

Los mismos filtros también funcionan con parámetros de URL. Entonces, por ejemplo, si la URL fuera:

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

Se filtraría por esos parámetros. Incluso muestra 3 páginas de propiedades como debería. Esto funciona muy bien, incluso en la carga inicial. Sin embargo, no funciona con la paginación, SI la URL se carga directamente. Si ingreso la URL anterior directamente en el navegador y la cargo, los resultados iniciales son correctos, pero al hacer clic en el botón Cargar más, cambia de página = 3 a página = 4 (correcto) pero agrega la segunda página de propiedades completa sin filtrar , y continúa haciéndolo, en lugar de continuar con la paginación filtrada.

¿Qué estoy haciendo mal?

Aquí está mi código (¡lo siento, es mucho!)

JS:

 jQuery(function($){ // AJAX Stuff for filters + load more button /* * Load More */ $('#prop_loadmore').click(function(){ $.ajax({ url : prop_loadmore_params.ajaxurl, data : { 'action': 'loadmorebutton', 'query': prop_loadmore_params.posts, // loop parameters passed by wp_localize_script() 'page' : prop_loadmore_params.current_page, // Get the current page }, type : 'POST', beforeSend : function ( xhr ) { $('#prop_loadmore').text( 'Loading...' ); $('#prop_loadmore').addClass( 'loading' ); }, success : function( posts ){ if( posts ) { $('#prop_loadmore').removeClass( 'loading' ); $('#prop_loadmore').text( 'More Listings' ); $('#main_posts').append( posts ); // $(".price-txt").digits(); // Add the commas! localStorage.setItem("posts", posts); prop_loadmore_params.current_page++; // Increase current page by 1 var params = new URLSearchParams(location.search); params.set('page', prop_loadmore_params.current_page); window.history.replaceState({}, "", decodeURIComponent(`${location.pathname}?${params}`)); if ( prop_loadmore_params.current_page == prop_loadmore_params.max_page ) $('#prop_loadmore').hide(); // if last page, hide loadmore } else { $('#prop_loadmore').hide(); // if no properties, hide loadmore } } }); return false; }); /* * Filter */ $('#filter').change(function(){ $.ajaxSetup({cache: false}); $.ajax({ url : prop_loadmore_params.ajaxurl, data : $('#filter').serialize(), dataType : 'json', success : function( data ){ // reset current page to 1 when filters on prop_loadmore_params.current_page = 1; prop_loadmore_params.posts = data.posts; // set max page prop_loadmore_params.max_page = data.max_page; found_posts = data.found_posts //First pull out the empty strings var formData = $('#filter').serializeArray().filter(function (i) { if(i.value != 'prop_filters') { return i.value; } }); //Now push formData to URL window.history.pushState('', 'title', '?' + $.param(formData) + '&page=' + prop_loadmore_params.current_page); $('#main_posts').html(data.content); $('.listings-count').text( found_posts + ' Real Estate Listings for Sale' ); if (found_posts > 9) { $('#prop_loadmore').show(); } if ( prop_loadmore_params.current_page == prop_loadmore_params.max_page ) $('#prop_loadmore').hide(); // if last page, hide loadmore // If not enough posts for 2nd page, hide loadmore if ( data.max_page < 2 ) { $('#prop_loadmore').hide(); } else { $('#prop_loadmore').show(); } } }); return false; }); });
