J'ai un filtre AJAX bien défini, en deux parties, une pour un bouton de chargement plus et une pour une sélection de filtres déroulants. Les deux rechargent une liste de propriétés sur le front-end dans AJAX et fonctionnent ensemble à l'unisson (par exemple, si je sélectionne le prix Min, le prix Max et le nombre de lits dans les listes déroulantes, la liste s'actualise et le bouton Charger plus fonctionne comme il se doit) .
Les mêmes filtres fonctionnent également avec les paramètres d'URL. Ainsi, par exemple, si l'URL était:
mydomain.com/?min_price=100000&max_price=5000000&beds=3&page=3
Il filtrerait par ces paramètres. Il montre même 3 pages de propriétés comme il se doit. Cela fonctionne très bien, y compris lors de la charge initiale. Cependant, cela ne fonctionne pas avec la pagination, SI l'URL est chargée directement. Si j'entre l'URL ci-dessus directement dans le navigateur et que je charge, les résultats initiaux sont corrects, mais en cliquant sur le bouton Charger plus, cela change page = 3 en page = 4 (correct) mais il ajoute la deuxième page de propriétés complétée non filtrée , et continue de le faire - plutôt que de poursuivre la pagination filtrée.
Qu'est-ce que je fais mal?
Voici mon code (désolé c'est beaucoup!)
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;
});
});
