How To Show Code Snippets In WordPress

WordPress is a powerful content management system that can display many types of media — including many different types of images and videos. Unfortunately, WordPress doesn’t display code snippets very well! 

In most cases, you can’t paste code directly into a new post because WordPress can’t tell if you want to process the code or render it. Highlighting code on a page that is surrounded by text can also be inconvenient for visitors to your site.

Fortunately, there are many solutions available for rendering code on a WordPress site. This post will share a few of the best solutions!

Although WordPress doesn’t display code snippets very well, it is still possible to add them using the

[pastacode lang=”markup” manual=”%3Ccode%3E%3C%2Fcode%3E” message=”” highlight=”” provider=”manual”/]


[pastacode lang=”markup” manual=”%3Cpre%3E%3C%2Fpre%3E” message=”” highlight=”” provider=”manual”/]


Of course, there are some issues with using this technique. The main issue is that WordPress will not render certain types of code. For example, if you posted the following snippet into the standard WordPress text editor, it would not render correctly:

[pastacode lang=”markup” manual=”%3Ccode%3E%3C%3Fphp%20echo%20%22Hello%20world%22%3B%20%3F%3E%3C%2Fcode%3E” message=”” highlight=”” provider=”manual”/]

WordPress would detect it is PHP code and not display it. You will have to use HTML character entities to display the content as expected. For example, the following is required in text mode to display the snippet correctly: 

Code Sample

If you aren’t the best at remembering HTML character entities, you can visit a website that will convert strings for you. You can also switch between visual and text editing modes to add your snippet with

[pastacode lang=”markup” manual=”%3Cpre%3E” message=”” highlight=”” provider=”manual”/]


[pastacode lang=”markup” manual=”%3Ccode%3E” message=”” highlight=”” provider=”manual”/]


This can be a bit time consuming if you need to add multiple snippets!

Another problem is the fact that the snippet will display using the theme’s styles. This might lead to the inclusion of unusual fonts that aren’t suitable for displaying code. You might not even have styles defined for the code tag, which will result in a very boring looking code that is hard to read. 

That last issue with displaying a code snippet using this technique is that it won’t have line numbers. Line numbers are a useful feature if you are discussing a piece of code and want to highlight a particular section.

This is how code and pre tags look when rendering a snippet:

You can display code snippets with more style by using one of the many great plugins out there. Many of these plugins also offer additional functionality that makes it easier to copy the code and share it with other people. Here are five of the best:

SyntaxHighlighter Evolved

SyntaxHighlighter Evolved Plugin

SyntaxHighlighter Evolved is one of the most popular WordPress plugins for displaying code snippets. It is simple to use and packed with great features. The main features of this plugin include:

  • Advanced syntax highlighting for multiple types of snippets including HTML, CSS and PHP using smart tags.

Using the plugin is easy. Simply wrap your code snippet in the appropriate smart tag for the language you are using. Here are a few examples:


[pastacode lang=”php” manual=”%5Bphp%5D%3C%3Fphp%0A%0A%2F%2F%C2%A0%20This%20is%20a%20PHP%20code%20snippet%0A%0Aecho%20%22Hello%20world%22%3B%0A%0A%3F%3E%5B%2Fphp%5D” message=”” highlight=”” provider=”manual”/]


[pastacode lang=”css” manual=”%5Bcss%5D%0A%0A%2F**%20A%20CSS%20code%20snippet%20**%2F%0A%0Abody%20%7B%0A%0Acolor%3A%20blue%3B%0A%0A%7D%0A%0Ah1%20%7B%0A%0Acolor%3A%20green%3B%0A%0A%7D%0A%0A%5B%2Fcss%5D” message=”” highlight=”” provider=”manual”/]


[pastacode lang=”markup” manual=”%5Bhtml%5D%0A%0A%3C!–%20This%20is%20an%20HTML%20snippet%20–%3E%0A%0A%3Ch1%3EThis%20is%20a%20heading%3C%2Fh1%3E%0A%0A%3Cp%3EThis%20is%20a%20paragraph.%3C%2Fp%3E%0A%0A%5B%2Fhtml%5D” message=”” highlight=”” provider=”manual”/]

This resulting code will look something like:

[pastacode lang=”php” manual=”%3Cpre%20lang%3D%22php%22%20title%3D%22A%20PHP%20example!%22%3E%0A%0A%3C%3Fphp%0A%0Aecho%20%22Hello%20world!%22%3B%0A%0A%3F%3E%0A%0A%3C%2Fpre%3E” message=”” highlight=”” provider=”manual”/]


[pastacode lang=”css” manual=”%3Cpre%20lang%3D%22css%22%20title%3D%22A%20CSS%20example!%22%3E%0A%0A%2F**%20A%20CSS%20code%20snippet%20**%2F%0A%0Abody%20%7B%0A%0Acolor%3A%20blue%3B%0A%0A%7D%0A%0Ah1%20%7B%C2%A0%0A%0Acolor%3A%20green%3B%0A%0A%7D%0A%0A%3C%2Fpre%3E” message=”” highlight=”” provider=”manual”/]


[pastacode lang=”markup” manual=”%3Cpre%20lang%3D%22html%22%20title%3D%22An%20HTML%20example!%22%3E%0A%0A%C2%A0%20%C2%A0%20%3C!–%20This%20is%20an%20HTML%20snippet%20–%3E%0A%0A%C2%A0%20%C2%A0%20%3Ch1%3EThis%20is%20a%20heading%3C%2Fh1%3E%0A%0A%C2%A0%20%C2%A0%20%3Cp%3EThis%20is%20a%20paragraph%3C%2Fp%3E%0A%0A%3C%2Fpre%3E” message=”” highlight=”” provider=”manual”/]
