我的 php 代码有问题。第一个站点上有一个包含所有数据的列表。数据表正确显示。表的最后一列是一个指向下一页的链接，该链接应传递行的 ID。
这是链接:
print '<a href="editsr.php?id='.$row['id'].'" class="btn btn-default btn1">Ändern</a>';
但我现在无法将数据输入到输入字段中进行编辑。表单显示正确，但我在每个输入字段中都有此错误:
Warning: Illegal string offset 'vorname' in /home_pr5/d/e/deniseli.ch/htdocs/www.deniseli.ch/T .... tor/editsr.php on line 130
S
这是 editsr.php:

最佳答案
仔细看看你的代码
在顶部，您正在使用 $user 变量，如下所示
$id = $_GET['id'];
$statement = $pdo->prepare("SELECT * FROM users WHERE id = :id");
$result = $statement->execute(array('id' => ['id']));
$user = $statement->fetch(); // here
在 php 代码的底部，您再次使用 $user 变量，如下所示
$id = $_GET['id'];
$user = "SELECT * FROM users WHERE id = :id"; // here
?>
在您尝试获取的输入上，例如 htmlentities($user['vorname']);
<div class="form-group">
<label for=inputVorname class="col-sm-2 control-label">Vorname</label>
<div class="col-sm-10">
<input class="form-control" id="inputVorname" name="vorname" type="text" value="<?php echo htmlentities($user['vorname']); ?>" readonly>
</div>
</div>
这就是每次输入都会出错的问题:)
