如何解决是否可以使用jQuery的datatables.js插件再通过PHP过滤器按钮从表中导出数据？
我创建了一个销售表格，其中选择了产品的销售日期和地点：
点击“ Szukaj”按钮后，即表示“搜索”或“过滤器”
使用PHP和MSQL查询提取数据库中的数据。显示销售结果之后
为什么？这是admin.PHP文件，其中在其中显示销售的位置，并在底部运行一个运行数据表的脚本：
<?PHP
session_start();
if (!isset($_SESSION['zalogowany']))
{
header('Location: index.PHP');
exit();
}
$connect = new PDO("MysqL:host=localhost;dbname=bukowski2","root","");
function fill_unit_select_Box2($connect)
{
$output = '';
$query = "SELECT * FROM users WHERE user_id!=7";
$statement = $connect->prepare($query);
$statement->execute();
$result = $statement->fetchAll();
foreach($result as $row)
{
$output .= '<option value="'.$row["user"].'">'.$row["user"].'</option>';
}
return $output;
}
?>

$(document).ready(function(){
$.datepicker.setDefaults({

});
$(function(){
$("#date").datepicker();
});
$('#filter').click(function(){
var date = $('#date').val();
var item_from=$('#item_from').val();
if(date != '')
{
$.ajax({
url:"filter.PHP",method:"POST",data:{date:date,item_from:item_from},success:function(data)
{
$('#order_table').html(data);
}
});
}
else
{
alert("Please Select Date");
}
});
});
</script>
和下面是filter.PHP文件，该文件使用PHP和MySQL查询从数据库中提取数据，我想使用DATATABLE插件按钮将其导出：

buttons \ js.js脚本文件中包含用于初始化表的js代码。这是代码：
$(document).ready(function() {
$('#example').DataTable( {
dom: 'Bfrtip',buttons: [
'copy','csv','excel','pdf','print'
]
} );
} );
解决方法
好的，我解决了。从打印结果的循环中删除标记就足够了，因为每次插入一行数据时都会插入标记。已关闭
