我目前正在使用一些不错的Material Design构建一个轻量级的博客平台,但我遇到了一个问题。我有一个带ID的表,我想在我的表中更改public的值,以便你可以隐藏博客中的文章,这样做我做了一个循环,但它只适用于第一个id而没有其他的身份证。这是我的代码:
try {
if (isset($_POST['submit'])) {
$stmt = $db->query('SELECT postID FROM blog_posts ORDER BY postID DESC');
while ($row = $stmt->fetch()) {
// set public based on the submitted value from your form
$public = empty($_POST['public'][$row['postID']]) ? 0 : 1;
// do the update
$stmt = $db->prepare('UPDATE blog_posts SET public = ? WHERE postID = ?');
$stmt->execute(array($public, $row['postID']));
header('Location: index.php');
}
}
} catch (PDOException $e) {
echo $e->getMessage();
}

提前致谢。

请将此header('Location: index.php');
放在while循环之外,不要覆盖$stmt
而是使用另一个:
//.......
//.......
while ($row = $stmt->fetch()) {
// set public based on the submitted value from your form
$public = empty($_POST['public'][$row['postID']]) ? 0 : 1;
// do the update
//Create another statement
$stmt2 = $db->prepare('UPDATE blog_posts SET public = ? WHERE postID = ?');
$stmt2->execute(array(
$public,
$row['postID']
));
}
header('Location: index.php');
//.......
//.......
