Developing a blog site, having issues displaying text while in edit mode

Blog body variable is being saved into mysql as:

$body = mysql_real_escape_string($_POST['body']);

Extracting it from DB like:

$body = nl2br($row['body']);

and using echo $body to show it.

I want users to be able to embed video, and use html tags in their blogs, the issue I'm having is when the user enters "edit" mode to ch开发者_运维知识库ange the blog, you can see all of the html linkbreak tags. Is there a way to show all html tags except for the linebreak tag?

There are a couple of things that are going on with your code sample. First, you should be using mysqli_real_escape_string instead of mysql_real_escape_string, here are a few reasons why.

Second, you don't want to use nl2br until you're displaying the text.
