Output filters
In Revolution, output filters behave like PHx in Evolution, except the filters are now built directly into the MODX engine. The syntax is:
modx
[[element:modifier=`value`]]Filters can be applied in sequence. Write them one after another (left to right):
modx
[[element:modifier:anothermodifier=`value`:andanothermodifier:yetanother=`value2`]]Filters can also be used to modify snippet output. The filter must be placed before all parameters (before the question mark):
modx
[[mySnippet:modifier=`value`? &mySnippetParam=`something`]]
