我不知道这有什么不对，没有错误，但它没有解决更新查询。我不知道它是最新代码还是旧代码。第一个代码是accommodation_server.php。
这是结构：
<?php
session_start();
$title_room = "";
$room_size = "";
$occupancy = "";
$bed = "";
$rate = "";
$others = "";
$others1 = "";
$others2 = "";
$others3 = "";
$others4 = "";
$id = 0;
$edit_state = false;
//connect to the database
$db = mysqli_connect('localhost', 'root', '', 'accommodation');
//update
if (isset($_POST['update'])) {
$title_room = $_POST['text_title'];
$room_size = $_POST['text_size'];
$occupancy = $_POST['text_occupancy'];
$rate = $_POST['text_rate'];
$others = $_POST['text_others1'];
$others1 = $_POST['text_others2'];
$others2 = $_POST['text_others3'];
$others3 = $_POST['text_others4'];
$others4 = $_POST['text_others5'];
$bed = $_POST['text_bed'];
$description = $_POST['text_description'];
$id = $_POST['text_id'];
mysqli_query($db, "UPDATE rooms SET title_room = '$title_room', room_size = '$room_size', occupancy = '$occupancy', rate = '$rate', bed = '$bed', others = '$others', others1 = 'others1', others2 = '$others2', others3 = '$others3', others4 = '$others4', description = '$description' where id=$id");
$_SESSION['msg'] = "Room Updated!";
header('location: accommodation.php');
}
//retrieve records
$results = mysqli_query($db, "SELECT * FROM rooms");
?>
这是accommodation.php
<?php include ('accomodation_server.php');
//fetch the record
if (isset($_GET['edit'])) {
$id = $_GET['edit'];
$edit_state = true;
$rec = mysqli_query($db, "SELECT * FROM rooms where id=$id");
$record = mysqli_fetch_array($rec);
$title_room = $record['title_room'];
$room_size = $record['room_size'];
$occupancy = $record['occupancy'];
$rate = $record['rate'];
$others = $record['others'];
$others1 =$record['others1'];
$others2 = $record['others2'];
$others3 = $record['others3'];
$others4 = $record['others4'];
$bed = $record['Bed'];
$description = $record['description'];
$id = $record['id'];
}
?>

答案 0 :(得分：-1)
mysqli_query($db, "UPDATE rooms SET title_room = '$title_room', room_size = '$room_size', occupancy = '$occupancy', rate = '$rate', bed = '$bed', others = '$others', others1 = 'others1', others2 = '$others2', others3 = '$others3', others4 = '$others4', description = '$description' where id='$id'");
再次在第二次
$rec = mysqli_query($db, "SELECT * FROM rooms where id='$id'");
如果你在查询后添加print_r（$ db），它会告诉你sql请求中是否有任何错误
