Custom code template development is already a feature included with Component Architect Pro, so you can take out a Professional subscription and start to develop you own versions of code templates straight away. Simply take a copy of one of the code templates supplied with Component Architect Pro and all the database information, folder structure and files are replicated so you can modify them at will.
Currently the best way to amend the code is via an IDE (Integrated Development Environment) such as Eclipse, PHP Storm or one of the many other IDE's available. In the next major release of the Component Architect Professional product a capability to amend files in the code template directly from Component Architect Professional is planned. This will be based on the Templates Manager introduced in Joomla! 3.2. This will be useful for minor amendments but the use of an IDE would still be preferable for major revision of code templates.
Documentation and guides on how to amend code templates will be provided to Component Architect Professional subscribers and support will also be provided via a subscriber only ticketing system. Please note though that the support provided is not to actually rewrite code templates for you but to answer questions on the use of the different mark-up codes and naming standards.
If you do require development of custom code templates that are beyond your technical capabilities then Component Architect can also provide a Custom Development Service to Professional subscribers (you must have a Professional subscription before we will even consider such work). All requests for Custom Development Services will be assessed and potential solutions, time scales and costs discussed and agreed with you, the client before work commences. Dependent on the type of request this may be a fixed price contract or on an hourly effort basis.
Either send your request via a Support Ticket or use the Contact Us form.
