チェックボックスを使用していくつかのパラメーターに基づいて検索結果をフィルター処理したい.ページネーションが機能する検索機能がありますが、すべてPHPで記述されています.レコードをフィルター処理したいのですが、これにはおそらくajaxリクエストとjqueryが必要ですここで同様のことを行いますhttp://www.proptiger.com/property-in-pune-real-estate.php左側のパネルには、データをフィルタリングするためのチェックボックスがあります。これは、検索クエリを保持し、結果を表示する div です。

<div style="margin-top:10px;" class="flt mapnewalert"> <?php //echo ucfirst($_SESSION['$cityName']) ?></div>
<div style="float:right" id="toppagesel">

チェックボックスのチェックでjs関数を記述し、パラメーターを.phpページに渡し、クエリを処理して結果を返す必要があることは理解していますが、それを実行して上記の現在のレコードをページネーションとともにレコードをフィルタリングします。これは参照用の私のページネーションクラスです

EDIT::jsファイルでこれを使って表示部分を解決しました
function changeResults(){
var data = { 'venue[]' : []};
$("input:checked").each(function() {
var chck1 = $(this).val();
//alert(chck1);
data['venue[]'].push($(this).val());
});
$.ajax({
type : 'POST',
url : 'process.php',
data : data,
success : function(data){
$('#project_section').html(data); // replace the contents coming from php file
}
});
}
しかし、私のページネーションはphpのように機能しません。ページネータークラスを追加しました。ページネーションが応答でも機能するようにするにはどうすればよいですか。
ありがとう
