Hello people,
I am a software developer and I’m new here.

I hope this is the right place to post this. If not what would be the better place, for this kind of query, and this objective?

I am missing the possibility to update an existing list of users with some new users. In other words, I need to add new users (basically new “email addresses”) to an existing list.

Be it on the command line (that i can ‘cron’), or an with an API (but it seems you don’t have any). The source format doesn’t matter. It could be a CSV file, or another table of (the same) database.

If there is no recommended and standard way to do it, then I would have to write a few SQL queries to put the new data directly into the phplist users database. But for that, I need to know which tables are involving, to write the proper queries so that they stay in sync.

How do I get started? What do you recommend?
Do I have to hack the import*.php files?
Or did someone already started a clean plugin to do that?

Best regards from France,
Johny
