Dropdown select multiple

[haitlaoussine]

Hello, 

I'm developing a plugin forWHMCS,  I need to know if there is a way to have a dropdown with select multi in WHMCS ?

I have set the 'Type' => 'dropdown', and the 'Multiple' => true, and the frontend is good, but is doesn't save the values in the database

Thank's

Nope.

Supported field types are “text”, “password”, “yesno” (checkboxes), “textarea”, “dropdown” and “radio”

IMO don't even start using _config() function. As you can see it is already limited and with time your addon could become so big and complex that you'll need to find alternatives. Moreover it doesn't support conditional options (e.g. Select A show B hide C).

Create a dedicated table (e.g. blabla_config) where you can store anything you need freely. This way you can create a dedicated page/interface if to configure your addon with text, password, multiselect, toggle, file uploader (...) inputs.

I agree with Kian, but:

This is technically possible by checking which option was saved. Of course, the condition is only processed when the option was saved, so it is probably a bit cumbersome for the end user.
If you are a hardliner, you could use javascript to modify the output, but this is overkill. A configuration page inside yourmodule_output is the easiest way.

Yeah, it's impractical 😔 anyway I was thinking about a more complex scenario. For example think about Country/Region dropdown combo. Select Italy and get Italian regions, select Germany and get German ones, select Morocco and instead of a dropdown with regions you have a text field. Not to mention you can end up with things like Germany + Italian region stored in database 😭

I've come across the same problem of multi-select but do not know how to do it, if the plugin is developed and live could you provide the url of it.
