我试图删除从PHP数据表的多个选定的行与mysql.But接收以下print_r($_POST);返回2行的数据：PHP删除的倍数行从数据表与复选框
阵列（[user_payment_request_length] => 10 [checked_id] =>数组（ [0] => [1] =>）[SELECT_ALL] => [bulk_delete_submit] =>）
没有数据要传送，使MySQL的过程成功。尤其是$pr_id这是一个整数。当我尝试打印它如下：
foreach ($idArrr as $pr_id) {
echo $pr_id;
}
显示数组到字符串转换错误。 这里是我的全码：
$(document).ready(function() {
$('input').val('');
});
$(document).ready(function() {
$('#user_payment_request').DataTable();
});
function deleteConfirm() {
var result = confirm("Are you sure to delete?");
if (result) {
return true;
} else {
return false;
}
}
$(document).ready(function() {
$('#select_all').on('click', function() {
if (this.checked) {
$('.checkbox').each(function() {
this.checked = true;
});
} else {
$('.checkbox').each(function() {
this.checked = false;
});
}
});
$('.checkbox').on('click', function() {
if ($('.checkbox:checked').length == $('.checkbox').length) {
$('#select_all').prop('checked', true);
} else {
$('#select_all').prop('checked', false);
}
});
});$stmt_payment = $mysqli->prepare('SELECT pr_id,pr_rqtime,pr_amount,pr_processor,pr_status,pr_date FROM payment WHERE user_id = ? ');
$stmt_payment->bind_param('i', $user_id);
$stmt_payment->execute(); // Execute the prepared query.
$stmt_payment->store_result();
$stmt_payment->bind_result($pr_id, $pr_rqtime, $pr_amount, $pr_processor, $pr_status, $pr_date);
?>

$stmt_delete_payment->bind_param('iisds', $pr_id, $user_id, $pr_rqtime, $pr_amount, $pr_processor);
if (!$stmt_delete_payment->execute()) {
echo '<script>swal("Error!", "Database error deleting payout request, please try again", "error");</script>';
echo '<script>setTimeout(function(){location.href = "withdraw.php";},2000); </script>';

// end of delete records

听起来像“$ pr_id”是一个数组 - 也许如果你尝试print_r（$ pr_id），那么它将开始变得更有意义。 –
@PaulColdrey我试着用print_r（$ pr_id），但不幸的是$ pr_id没有传递任何值。这是我得到的输出'Array（[0] => [1] =>）' – mimi
