Dynamic configuration options for Textformatter module?

[johannes]

Hello Processwire community,

I am currently writing a configurable Textformatter module. For the configuration page I need a dynamic set of options, each consisting of two fields like so:

Option:

name1:value1

name2:value2

and so on…

At the moment I am using a JSON string in a text field but I was wondering if there is a better way to do this? Ideally I would be able to use a repeater, but I think that's not possible for a module configuration page, correct?

What's the best way to achieve this?

Hi johannes and welcome!

If you only need to store key-value pairs, ProcessWire often uses a simple textarea where each line corresponds to a key/value pair.

In your code, you can get the keys/values by using PHP's explode function (newline as a delimiter).

Another possibility would be to dynamically create a new input field when clicking a button, but this requires some javascript to work.

I don't think that you can use an existing inputfield, but I might be wrong

Thank you, that sounds good, I'll give that a try. The person configuring the module is the developer in most cases anyway, so it doesn't need to be that user friendly.
