Macro format... %IF_CONTEXT_VALUE_BEGIN(METADATA_VALUE:field name,match value)%Text you want to display if there is a match %IF_CONTEXT_VALUE_ELSE%Text you want to display if there isn't a match %IF_CONTEXT_VALUE_END% For example, if you want to display one message to users who are logged in, and another message to those who aren't, you'd use... %IF_CONTEXT_VALUE_BEGIN(LOGGED_IN,TRUE)%Congratulations, you are logged in. %IF_CONTEXT_VALUE_ELSE%Please log in. %IF_CONTEXT_VALUE_END% Or if you want to display nothing if there is no value in the Cover field, but otherwise to display an image call containing that value... %IF_CONTEXT_VALUE_BEGIN(METADATA_VALUE:Cover,)% %IF_CONTEXT_VALUE_ELSE%img src="%TAG_VALUE_OBJECT(Cover,)%" %IF_CONTEXT_VALUE_END% This is useful if you want to display a cover image for those publications that have one...without generating a broken image call for those that don't. Using Macros to place a tag value from a title when designing a title's content page: You can add any meta tag value from the title containing the content page by placing the macro: %TAG_VALUE_PARENT_OBJECT(tag name,default value if not found)%.
