In MODx, it is always preferable to link to another page using the document id instead of using the friendly alias because sometimes MODx Evolution has a package that is appearantly capable of using the alias instead of the document id to provide a working link to another page.

The reason you shouldn’t use the alias instead of the document id is because it isn’t unheard of to have google or other search engines incorrectly access another page perhaps one that isn’t even available.

Using the document id is done in the following manner for Evolution:

>a href = "[˜77˜]"<Link to document 77>/a<


Using the document id is done in the following manner for Revolution:

>a href = "[[˜77]]"<Link to document 77>/a<


The documentation for MODx Revolution is really geat and should be used to learn additional things.

Hope this helps!
