我有一个页面，列出该页面上的所有属性。该记录是根据单击的复选框进行过滤的。我该如何进行分页。当未应用任何过滤器时，我希望对记录进行分页。当还应用过滤时，我希望分页也应用于显示的记录。我该怎么办？下面是一个 进行过滤的示例代码。谢谢。
这是我到目前为止的分页代码。但是，如何将其应用于过滤的记录？
$totalProperty = "SELECT * FROM property_listing WHERE property_status = 'approved' ";
$allProperty = mysqli_query($connection, $totalProperty);
$totalProperties = mysqli_num_rows($allProperty);
$showRecordPerPage = 4;
if(isset($_GET['page']) && !empty($_GET['page'])){
$currentPage = $_GET['page'];
}else{
$currentPage = 1;
}
$startFrom = ($currentPage * $showRecordPerPage) -
$showRecordPerPage;
$lastPage = ceil
($totalProperties/$showRecordPerPage);
$firstPage = 1;
$nextPage = $currentPage + 1;
$previousPage = $currentPage - 1;
分页：
<div class="pagination">
<nav aria-label="Page navigation example">
<ul class="pagination">
<?php if($currentPage != $firstPage) { ?>
<li class="page-item">
<a class="page-link" href="?page=<?php echo $firstPage ?>" tabindex="-1" aria-label="Previous">
<span aria-hidden="true">«</span>
</a>
</li>
<?php } ?>
<?php if($currentPage >= 2) { ?>
<li class="page-item"><a class="page-link" href="?page=<?php echo $previousPage ?>"><?php echo $previousPage ?></a></li>
<?php } ?>

下面也是用于过滤的ajax代码
$(document).ready(function(){
filter_data();
function filter_data()
{
$('.filter_data').html('<div id="loading" style="" ></div>');
var action = 'fetch_data';
var limit = 4;
var start = 0;
var actions = 'inactive';
var minimum_price = $('#hidden_minimum_price').val();
var maximum_price = $('#hidden_maximum_price').val();
var brand = get_filter('type');
var ram = get_filter('feature');
$.ajax({
url:"fetch_data.php",
method:"POST",
data:{action:action, minimum_price:minimum_price, maximum_price:maximum_price, brand:brand, ram:ram,},
success:function(data){
$('.filter_data').html(data);
}
});
}
function get_filter(class_name)
{
var filter = [];
$('.'+class_name+':checked').each(function(){
filter.push($(this).val());
});
return filter;
}
$('.common_selector').click(function(){
filter_data();
});
$('#price_range').slider({
range:true,
min:100,
max:9000000,
values:[100, 9000000],
step:100,
stop:function(event, ui)
{
$('#price_show').html(ui.values[0] + ' - ' + ui.values[1]);
$('#hidden_minimum_price').val(ui.values[0]);
$('#hidden_maximum_price').val(ui.values[1]);
filter_data();
}
});
});
答案 0 :(得分：0)
要生成分页，请使用LIMIT子句，该子句将带有两个参数。第一个参数为OFFSET，第二个参数应从数据库返回多少记录。
