Question

我不明白，因为到目前为止我可以删除评论。但是，当我尝试更新它们时，它不会在数据库中更新。更令我震惊的是，没有错误信息解释原因。这有什么特别的原因吗？

<table class="table table-bordered table-hover">
                    <thead>
                        <tr>
                            <td>Id</td>
                            <td>Post Author</td>
                            <td>Author Email</td>
                            <td>Post Content</td>

您的变量拼写不同$ comIdApp vs $ commIdApp

$comIdApp = $_GET['approve'];
$approveStat = 'approved';

$approveComment = $conn->prepare("UPDATE comments SET comment_status = ? WHERE comment_id = ?");
$approveComment->bind_param("si", $approveStat, $commIdApp);

绝对困惑，为什么这个特定的查询不起作用？
