MODX Revolution Tags

MODX tags have a slightly different style in MODX Revolution. All tags now start with [[ and end with ]]. This makes the document parser faster and more efficient since the complex code used to identify the old-style tags is gone. Once you get used to the new tag format, you'll find that it's easier and less likely to lead to entry errors.

Here's a list of the tag changes:


Resource Tags
[*ResourceField/TV*] [[*ResourceField/TV]]
Chunk Tags
{{Chunk}} [[$Chunk]]
Snippet Tags
[[Snippet]] [[Snippet]]
Placeholder Tags
[+Placeholder+] [[+Placeholder]]
Link Tags
[~ResourceId~] [[~ResourceId]]
Setting Tags
[(system_setting)] [[++SettingName]]
Language Tags
No Tag [[%LanguageStringKey]]
Comment Tags (2.1.4+)
No Tag [[-comment]]


Cache Control

[!Snippet!] [[!Snippet]]
No Tag [[!$Chunk]]
No Tag [[!*ResourceField/TV]


As of MODX 2.1.4, you can disable any tag by putting a minus sign immediately after the opening square brackets. This form can also be used for comments in the page content that are not intended to be shown on the rendered page. The tag will be ignored and removed from the output:

[[-SnippetName? &argumentName=`value`]]
[[-This Is a Comment]]

With language tags, you have the option of specifying the language, namespace, and topic using properties in the tag:

[[%LanguageStringKey? &language=`en` &namespace=`NameSpaceName` &topic=`TopicName`]]

Note that in Revolution, you can put arguments in the URL for use with $_GET by simply adding them to a link tag:

[[~12? &argumentName=`value`]]

Revolution will work out the appropriate form.
