Modify login page without change original code

[Ratana_Surya]

Hi, I’m new to OpenEMR and want to try to explore the changes in it based on user needs

How do I change the appearance with code without changing the original code, is that possible? for example login page

I see there are several similar topics, but there are still none

Extend Openemr with custom modules and Stand independent of code changes

Hi, There are certain situations where clinics require customization which cannot be generalized . When this is done through openemr code base it will create problem when upgrade to the next version. Each upgradation require a review and merging . Is openemr provide a method to address this problem. Can a separate main menu built into the system which will be building from a database table , In that way this will be independent of code changes.

@brady.miller maybe can help this question?

Thanks

Search the forum on how to make a custom module. I also made a tutorial video on the OpenEMR youtube channel on making modules: https://www.youtube.com/watch?v=LYA8MosIWF0&t=1s

There are extension points to allow you to add your module’s template directory in the TWIG rendering engine’s environment. At that point you can override the template files of the login page without touching core code.

My skeleton module even has an example that overrides the login page that you can look to as an example.

@Ratana_Surya, you can take a look at some generic code we have made available here. It does require a small patch to a library that is invoked by all scripts. That change will check couple of tables to see if your local installation has any active customization(s) for current script. Since we wanted to treat standard code as a blackbox, we use PHP’s shutdown function feature to perform modifications to html generated by standard scripts.

Best.

@mdsupport Thank you for the answer, hopefully this can help me understand more in application development
