Develop free-text plugin with feedback

WIP plugin, still has issues with answer form submit. Does not save data and goes to previous question instead of next.

Ready to review and merge if no changes needed.

Just one thing before this can be merged: please use global namespace indicator before every global function call: \ array_key_exists (....
In general this has a lot of potential for improvements, for example:

• Provide a field with number of phrases required to score max (currently only answer with all phrases allows to score max).
• Provide phrase variants so any of the variants will count as a phrase found (phrases setting textarea: each row is a phrase and variants separated by a pipe).
• Allow 1 or 2 letter difference when searching with feedback like "phrase found but you have a typo".

Let's leave all those things as follow-ups though, fix the global namespace prefix and merge for now.

I've added global namespace indicators before every global function call -- I think I got 'em all!

field with number of phrases required to score max

I'm not sure if I understand the usefulness of this, to my mind a teacher would only add the match-phrases that they wanted to see in the student answer, so if they get all of them they get 100% score. But maybe you're seeing a use case that I'm missing where this would be needed?

phrase variants so any of the variants will count as a phrase found (phrases setting textarea: each row is a phrase and variants separated by a pipe)

Excellent idea! Already included in the plugin from the beginning. 😁

Allow 1 or 2 letter difference when searching with feedback like "phrase found but you have a typo"

I would LOVE to add this feature, but couldn't find a way to do it that isn't super resource-intensive. Can you suggest a method?

Looks good! as for incomplete string matching - this probably needs a dedicated method that'd iterate over the string checking character by character, if we have a match we check the next character etc. It's not going to be very heavy, just writing it may be challenging. One day maybe.

Automatically closed - issue fixed for 2 weeks with no activity.
