PHP in the document content

Hi everybody,

Is there anyway to write PHP code, or call a snippets inside a document content? (not template)

You can call a snippet in the document content in the exact same way as you would call it in a template.

Indeed, all MODx tags can be called in any HTML code, whether in a template, a chunk, a TV or the document content.

You cannot write PHP code in the document content. All PHP is isolated to snippets, plugins, and modules.
