Just I have one doubt that why one component or module is compatiable with one version of Joomla(Ex-> Joomla 2.5) but the same component or module is not compatiable with another version of Joomla(Ex-> Joomla 3.0).
If I want to make it compatiable with another versions also then what changes I need to do
分享 The problem with compatibility is Joomla! is a delicate one.
The Joomla! platform / API is evolving all the time (especially between LTS releases like 1.5 and 2.5), so classes / functions are changed or deprecated and later removed. New things are added and so on.
For developers is possible to maintaing a component under different versions (I am not saying it's easy), but they need to know what has changed in the API.
Also constructs like (in pseudocode)
if (Joomla! version == 1.5) then do this else do that.
are used to make sure some parts of the code are used only in a specific version.
To better understand what is going on have a look at:
