我试图根据我正在使用的查询来保持我的分页,但我的问题是,它只适用于分页的第一页,之后查询将恢复为没有过滤器的标准查询(第一页显示我的过滤,但第二页显示所有结果)。我想知道当我点击我的页面时是否有一个有效的方法将继承我的过滤查询,我现在对如何实现这一点感到茫然。这是我目前的代码:
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css">
<style type="text/css">
#win-range, #gaa-range, #sv-range{
width: 160px;
font-size: 10px;
margin: 0 auto;
}
#win-range a, #gaa-range a, #sv-range a{
margin-top: 0px !important;
padding: 0 !important;
}
</style>

$(function(){
$("#win-range").slider({
range: true,
min: 1,
max: 1000,
values: [1, 1000],
slide: function(event, ui) {
// in order to pass the user selected values to your app, we will use jQuery to prepopulate certain hidden form elements, then grab those values from the $_POST
$("#minwins").val(ui.values[0]);
$("#maxwins").val(ui.values[1]);
$("#winamount").val(ui.values[0] + " - " + ui.values[1]);
}
});
$("#winamount").val($("#win-range").slider("values", 0) + " - " + $("#win-range").slider("values", 1));
});
$(function(){
$("#gaa-range").slider({

$("#mingaa").val(ui.values[0]);

}
});
$("#gaaamount").val($("#gaa-range").slider("values", 0) + " - " + $("#gaa-range").slider("values", 1));
});
$(function(){
$("#sv-range").slider({
range: true,

在会话中保存搜索过滤器,并始终检查是否为任何搜索设置了会话值,并将该数据传递给query.until,除非没有人重置该搜索条件,并且当您的用户将该搜索条件重置为null然后放入该会话搜索变量的会话中的值为空白。

您需要将所有过滤条件传递给分页链接,例如
$filter = "minwins={$minwins}&maxwins={$maxwins}&mingaa={$mingaa}&minsv={$minsv}&maxsv={$maxsv}&q={$querySelection}";
if($pg > 1){
echo "<a href=\"$thisroot?pg=$p&$filter\"><< prev</a> ";
}
for($i=1; $i<=$num_pages; $i++){
if($i!= $pg){
echo "<a href=\"$thisroot?pg=$i&$filter\">$i</a> ";
}else{
echo "$i ";
}
}
if($pg < $num_pages){
// INSERT QUERY STRING VARIBLE TO CARRY OVER DB QUERY
echo "<a href=\"$thisroot?pg=$n&$filter\">next >></a>";
}
在从$ _POST获取过滤条件的代码中,将其更改为$ _REQUEST,因为它应该从URL($ _GET)获取。
实施例
$minwins = $_REQUEST['minwins'];

您可以随时使用以下内容创建网址密钥列表(过滤器)。
foreach($_GET as $key => $value){
$url_keys .= $key . "=" . $value . "&";
}
然后将其添加到您的网址中以显示下一页/上一页。
echo "<a href=\"$thisroot?pg=$n&$url_keys\">next >></a>";
然后,您将通过URL传递过滤器,并在下一页上访问它们。
