How to post code when you leave a comment

Sometimes you want to leave a comment and post code to demonstrate what is or isn’t working. For security though, pure HTML and PHP is filtered out – otherwise evildoers could post malicious code wherever they can.

In this screencast I will show you how to post code in comments so it can be displayed but not executed. This is meant to be for WordPress, but may well work with any system that let’s you post as a user.

Enjoy!

Workshop: How to post Source Code in your Comments

In this workshop I’ll show you how you can make source code show up in your comments. I’ll also show you how to format it so it looks different to ordinairy text.

By default, WordPress strips out most HTML tags for security reasons. That’s a good thing, however if you’d like to share some HTML or PHP source code with someone it won’t show up. The workaround is to paste the code into an empty post via the visual editor, then switch to the HTML editor and copy the resulting transcoded characters.

This works because single characters are not executable by the web browser and hence do not pose a security risk. It’s a bit tedious if you deal with code a lot, but it’s a safe solution and does not require any plugins.

Enjoy!
