[英]PDO Fetch statement only retrieves first column
As the title states, I am only able to grab the id column, I am getting an Undefined index error for the others.正如标题所述,我只能获取 id 列,其他人收到未定义的索引错误。
My code:我的代码:
if(isset($_SESSION['id'])) {
$presh = $_SESSION['id'];
$stmt = $pdo->prepare("SELECT id FROM users WHERE id = :id");
$id = $presh;
$stmt->execute(array(':id'=>$id));
$accountinfo = $stmt->fetch(PDO::FETCH_ASSOC);
}
Later on in my code I reference it as such:后来在我的代码中,我这样引用它:
Karma <span id="kcurrent"><?php echo $accountinfo["karmacurrent"]; ?></span> | <span id="ktotal"><?php echo $accountinfo["karmatotal"]; ?></span>
The rows do exist and they are filled, what am I doing wrong?这些行确实存在并且它们已被填充,我做错了什么?
You can only select the id
column because that is all you have in the query.您只能选择id
列,因为这是您在查询中的全部内容。
Try something like this尝试这样的事情
if (isset($_SESSION['id'])) {
$presh = $_SESSION['id'];
$stmt = $pdo->prepare("SELECT id, karmacurrent FROM users WHERE id = :id");
$id = $presh;
$stmt->execute(
array(
':id'=>$id
)
);
$accountinfo = $stmt->fetch(PDO::FETCH_ASSOC);
}
Basically you were only retrieving the ID
from the table instead of the other columns.基本上,您只是从表而不是其他列中检索ID
。
