Possibility to use arrays in fields

[jg-development]

Hi,

I want to post 2 addresses in one request.
(like billingaddress and deliveryaddress)
It seems Apigility cannot work with a fieldname like "billingAddress[salutation]". In the config this is just a string and not an array. Is it in any way possible to use input parameters as arrays?

Greetings Jan

I made a quick patch which works with the multiform and can handle flat arrays. Deep arrays foo[bar[baz]] are not supported only foo[] will work with this patch.

It will behave somewhat like the $_POST. Thats why we remove the [] from the name

I am not exactly sure where you do not manage to configure your nested field. But Apigility is definitely able to handle such cases. Check an example here on stackoverflow.
If this is not what you mean then please be more specific about where the configuration is failing.

When i was implementing your SO solution i had the feeling that it's for a fixed list? What if i would want to accept a normal array.

So my post could contain:

foo-bar[] = 1
foo-bar[] = 2
foo-bar[] = 3

@Wilt i found some other posts of you regarding this aswell as the post about the raw $data param we have in the methods. I am using this raw $data param, and that doesnt seem to work with arrays.

[Wilt]

I am not sure what you want to achieve. From the address example at the beginning I assumed you want to post a collection of addresses. But with your last foo-bar example it seems you simply want to post some array values. Do you want to post an array variable or a collection?
Can you be more explicit about your data type?

[michsk]

Array values as defined in foobar example. And get them from the raw data param which we have in the controllers

[Wilt]

Maybe the problem lies in your json structure. If I post data like this it works totally fine:

{
    "foo-bar": [1, 2, 3]
}

[michsk]

No, i use multiform

Created a pull request for this, maybe that makes it more obviouse; pull request: zfcampus/zf-content-negotiation#57
