I created a form where users can enter html code and it outputs their code in another textarea. The problem is that if the html the user enters has a textarea in the code, the in their code breaks my textarea form. I see other sites display any html correctly so how is this done without breaking the form and allowing the user to copy it so that it still remains as and not some converted code so they can paste it on their webpage?
Ah crap yeah I figured it out, in fact the problem wasn’t with the htmlspecialchars code alone I forgot to add a return to one of my functions haha. Thanks guys.
Represent characters that have special meaning in HTML using entities. Since you are using PHP, use htmlspecialchars
