"Official Code" field to something else

[KMaN1985]

On the new user registration page, how do I change the name of the "Official Code" field to something else?

You should define a sub-language.
In the administration > Configuration settings part, search for "sub-language" and you should find an option to activate them.
Then go to "Languages" (from the platform block on the admin page) and choose the most common language for your users, then click on the last icon (double arrow) to create a new sub-language based on that one.
Search for "Official code" and replace all terms with new terms where "Official code" is transformed to whatever you need.
Finally, enable the sub-language (in the languages list) and disable the parent language. It can be tricky if a lot of students or courses are already set to use the parent language, but I'm sure you'll find your way around.

Your main/lang/ directory has to be writeable by the web server so it can save the terms for the sub-language in a new sub-directory of main/lang/

The Official Code field is NOT mandatory by default in Chamilo, but it depends on your configuration. To hide it properly, you must first go to Administration → Configuration → Profile, find the "Official Code" field, and change it from Mandatory to Optional or Not visible, then save the changes. After that, you can hide it with CSS

/html/web/css/themes/chamilo/default.css

#official_code, 
label[for="official_code"],
.form-group:has(#official_code) {
    display: none !important;
}

Another more professional solution is to generate an automatic code that auto-populates the official_code field without displaying it in the form (for this, official_code must be set to mandatory or optional).

Create the file -> /html/web/js/custom.js

document.addEventListener('DOMContentLoaded', function() {
    const officialCodeField = document.getElementById('official_code');
    if (officialCodeField) {
        officialCodeField.value = 'USER-' + Date.now();
        officialCodeField.closest('.form-group').style.display = 'none';
    }
});

then include it in the template -> /html/main/template/default/layout/head.tpl

Before /head, add:

<script src="{{ _p.web }}js/custom.js"></script>
