Question

这是收到错误的代码：

session_start();
$user = $_SESSION["username"];

$sql = "SELECT cost FROM rooms
        WHERE rid = $rNumber";
$results = mysqli_query($conn, $sql)
or die ('Problem with query' . mysqli_error($conn));

$row = mysqli_fetch_array($results);
$sql2 = "INSERT INTO bookings (rid, username, checkin, checkout, cost)    
         VALUES ($rNumber, $user, $cInDate, $cOutDate, $row['price'])";  //this line is where the error occurs
$results2 = mysqli_query($conn, $sql2)
or die ('Problem with query' . mysqli_error($conn));

我似乎遇到了这个错误：

unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING

我已经尝试检查有关同一错误的其他帖子，我收集说我必须使用（。）连接一些东西，但我不知道是什么。我已经在sql之前回应了变量并且它们存在。

Answer 1

请改变这一行。

$sql2 = "INSERT INTO bookings (rid, username, checkin, checkout, cost) VALUES ('$rNumber', '$user', '$cInDate', '$cOutDate', '{$row['price']}')";

我还从您的查询中解决了MySql语法错误：P
