Description:

We do not allow for API calls to use multiple arguments for anything but ids. The goal of this PR is to allow them.
Steps to test and reproduce this PR:

Make simillar API calls with multiple arguments for something else than ids

/api/contacts?where[0][col]=global_customer_id&where[0][expr]=in&where[0][val]="10","11"
/api/contacts?where[0][col]=global_customer_id&where[0][expr]=in&where[0][val]=10,11

They don't work

They should work correctly now

Hi there!
It has been decided to not create any extra Mautic 2 minor versions (which means no more features in M2) knowing that Mautic 3 is coming very soon.

We now want to integrate your contribution in the Mautic 3 roadmap as 3.1.0 candidate.

How to do?

1. Check if your feature or enhancement is still missing and relevant in Mautic 3
2. If Yes: rebase your PR against the 3.x branch
3. If No: please consider closing your PR if you are absolutely sure that the feature has made it into Mautic 3 already

Please report results by commenting on your PR to make us administration easier.

---

You can more information on how to do all of that on this blog post "Getting you PR ready for Mautic 3".

@galvani This PR is still based on Mautic 2. Could you please rebase it against the staging branch for Mautic 3 and to trigger a code coverage report? Thanks!

Bumping to 3.2 as this PR requires updating for 3.x and rebasing. cc @escopecz @alanhartless

@npracht yes, it is.

[escopecz]

Works for me 👍

[RCheesley]

@escopecz any chance you could offer a query to use with sample data to test this?

[escopecz]

Here is CURL. Paste it to a command line but update the values in capital letters:

curl "https://URL/index_dev.php/api/contacts?where%5B0%5D%5Bcol%5D=firstname&where%5B0%5D%5Bexpr%5D=in&where%5B0%5D%5Bval%5D=John,Jane" \
     -u 'USERNAME:PASSWORD'

In order to get some contacts in the response you have to have some contacts with first name of John and/or Jane

Looks good.
Works for me
Unit test included

Then approve it 👍
