ShowMeta
CMain::ShowMeta( string id, string meta_name = false, bool bXhtmlStyle = true )
The method displays the page property as the META tag. The method allows to use special characters (HTML entities) in the property values.
If the page does not have the required property, the method searches for the one in parent sections recursively up to the site root. If the property value is not defined, the method will display empty string.
This method utilizes the delay function technology allowing to specify meta tags (using CMain::SetPageProperty or CMain::SetDirProperty) after the site prologue is displayed.
Non-static method.
