未知列 $name php 和 sql
Unknown column $name php and sql
我正在处理一个需要将数据插入数据库的项目,但我不断收到此错误:致命错误:未捕获的 PDOException:SQLSTATE[42S22]:未找到列:1054 未知列“$name”在 'field list' 中 /opt/lampp/htdocs/ramen.php:27 堆栈跟踪:#0 /opt/lampp/htdocs/ramen.php(27): PDOStatement->execute(Array) #1 { main} 在第 27 行 /opt/lampp/htdocs/ramen.php 中抛出
这是第 27 行:
$stmt-> execute(array(':content' => $_POST['content']));
这是那段代码:
if(isset($_POST['content'])){
$name = $_SESSION['name'];
echo $name;
$sql = 'INSERT INTO notes_ (Text, User) VALUES (:content, $name);';
$stmt = $pdo->prepare($sql);
$stmt->execute(array(':content' => $_POST['content']));
}
将您的引号从单引号更改为双引号。您可以将变量注入双引号字符串。
if(isset($_POST['content'])){
$name = $_SESSION['name'];
echo $name;
$sql = "INSERT INTO notes_ (Text, User) VALUES (:content, $name);";
$stmt = $pdo->prepare($sql);
$stmt->execute(array(':content' => $_POST['content']));
}
不过如果
会更好
if(isset($_POST['content'])){
$name = $_SESSION['name'];
echo $name;
$sql = 'INSERT INTO notes_ (Text, User) VALUES (:content, :name);';
$stmt = $pdo->prepare($sql);
$stmt->execute(array(':content' => $_POST['content'], ':name' => $name));
}
