How to Include Code in WordPress Posts

If you’ve ever tried to insert code into a WordPress post, one of the following has probably happened to you:

• Your HTML code was rendered as such.
• WordPress stripped the code from the post entirely.
• WordPress turned "straight quotes" into “curly quotes” — not good if you want your users copying/pasting code from your blog!

Here’s how to get around these annoying problem and make the code show as-is:

1. Put the code into a basic text processing program (like Notepad), and perform the following find/replace operations:

   Find	Replace
   <	&lt;
   >	&gt;
   "	&quot;

2. Click the “Code” tab on the WordPress post composition page, and then paste in the “fixed” code.

3. Be sure to encase your code in a <code> tag for purposes of semantic correctness.
