How to escape HTML in Liferay Freemarker?

Sometimes we need to show the HTML when displaying data. This post shows how to escape HTML in Liferay Freemarker.

These are some of the ways to escape HTML in Freemarker templates in Liferay.

Using Liferay Util to escape HTML

We can use HtmlUtil in both Freemarker and Velocity, so this code should work on both:

<#-- Assuming that curEntry.getContent() returns HTML  -->
${htmlUtil.escape(curEntry.getContent())}

Using Freemarker to escape HTML

Liferay 6.2 and Lower

If we are using Liferay 6.2 or below, then we need to use the old Freemarker method for escaping HTML:

<#escape x as x?html> ${curEntry.getContent()} </#escape>

Liferay 7

I believe Liferay 7 is using the latest version of Freemarker, so the method is different:

${curEntry.getContent()?esc}

 For references and more details on what else can we escape, view the following sites:

• Liferay way (HtmlUtil)
• Freemarker way (Liferay 6.2 and Below)
• Freemarker way (Liferay 7)
