我試圖刪除從PHP數據表的多個選定的行與mysql.But接收以下print_r($_POST);返回2行的數據：PHP刪除的倍數行從數據表與複選框
陣列（[user_payment_request_length] => 10 [checked_id] =>數組（ [0] => [1] =>）[SELECT_ALL] => [bulk_delete_submit] =>）
沒有數據要傳送，使MySQL的過程成功。尤其是$pr_id這是一個整數。當我嘗試打印它如下：
foreach ($idArrr as $pr_id) {
echo $pr_id;
}
顯示數組到字符串轉換錯誤。 這裏是我的全碼：
$(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>';
}
}
$stmt_delete_payment->close();

}
// end of delete records
$stmt_payment->close();

聽起來像「$ pr_id」是一個數組 - 也許如果你嘗試print_r（$ pr_id），那麼它將開始變得更有意義。 –
@PaulColdrey我試着用print_r（$ pr_id），但不幸的是$ pr_id沒有傳遞任何值。這是我得到的輸出'Array（[0] => [1] =>）' – mimi
