推薦答案
您在此行中的一個(gè)字段不存在，請檢查它們.
One of your fields on this line doesn't exist,check them.
$sql = "SELECT name, kalender_ID FROM kalender WHERE ersteller_ID = ?";
此外，您應(yīng)該檢查 $stmt.
Also, you should be checking for $stmt.
$db = new mysqli("localhost","root","","karmintalender");
$owner_ID = 1;
$sql = "SELECT name, kalender_ID FROM kalender WHERE ersteller_ID = ?";
$stmt = $db->prepare($sql);
if($stmt){
$stmt->bind_param("i", $owner_ID);
$stmt->execute();
$stmt->bind_results($name, $kalender_ID);
while ($stmt->fetch()) {
echo $name . " " . $kalender_ID;
}
}
