通过jQuery Ajax传递用户输入的文本，然后将结果输出给用户

Question

I need help understanding the proper sequence of filtering data when sending user inputted comments through ajax.

My input textarea data is filtered like so

   $comment  = htmlentities(addslashes($_POST['comment']));

And I input that into the database. I need it to simply be safe text that displays symbosl. Now I need to show this content to a member with all the slashes they put in, in their comment.

I don't want to see

    The comment\'s not so pleasant to read.

I don't know how to google this question.. or formulate the sentence. I wish to be able to return a nicely formatted comment using ajax aswell. Can anyone point me in the right direction? I just wish not to be hacked :x

Answer 1

Have you tried to strip the slashes before printing?

echo stripslashes($str);
