提交后如何显示即时发布的评论

Question

I am using ISSET condition to add comment on the page after saving it to database.

if (ISSET($_POST['comment_submit'])) {

    $comment_author = $_POST['comment_author'];
    $comment_content = $_POST['comment_content'];
    $post_id = $_POST['post_id'];

    if ($comment_content!="") {
        $new_comment = mysql_query("INSERT INTO comment (post_id, comment_author, comment_content, comment_date) VALUES ('$post_id', '$comment_author','$comment_content', now())");
    }
}

but after redirecting to same page its not showing comment posted recently. On refersh it starts displaying.

Answer 1

将在数据库中插入数据的代码放在插入查询之后。

Answer 2

If you are redirecting the user to same page, you won't get values in $_POST variable, since the form is not submitted again. You may have to store comment_author and comment_content values in session or you may have to pass these values while refreshing the page.

Answer 3

it seems that you're using pure php only.

• first thing you must do is to have a query that list down the available comments inside your db.
• second is posting your data and saving it.
• third, redirect your page to the comment section you're viewing.. use

header("Location: url")
