Firebase PHP Data Submission - arrayValue, mapValue

Question

I am trying to push data to a firestore DB using PHP and the Google apis.

Inside the documentation and examples I have seen around the web, I am able to use mapValue and arrayValue when sending data.

The example I am using is as follows:-

[
    "orderName" => [
        "stringValue" => "Gbeila Aliu Wahab"
    ],
    "orderLocationName" => [
        "stringValue" => "Accra Mall Limited"
    ],
    "orderTotalAmount" => [
        "doubleValue" => 150.5
    ],
    "orderDescription" => [
        "stringValue" => "Lorem Ipsum is simply dummy text of the printing and typesetting industry"
    ],
    "orderLocationGeoPoints" => [
        "geoPointValue" => (object) [
            "latitude" => 5.5557, 
            "longitude" => -0.1963
        ]
    ],
    "orderStatus" => [
        "stringValue" => "NotAssigned"
    ],
]

This works perfectly fine, but when I attempt to send an object or an array I get the following error returned to me:-

"message": "Invalid JSON payload received. Unknown name \"map_value\" at 'document.fields[0].value': Proto field is not repeating, cannot start list.",

when attempting to map the value using the following code:-

"orderName" => [
    "mapValue" => ["Gbeila Aliu Wahab", 123]
]

// or

"orderName" => [
    "arrayValue" => [
        "first" => [
            "stringValue" => "test"
        ], 
        "second" => [
            "stringValue" => "test123"
        ]
    ]
]

I have tried many variations to try to get this to work.

How am I supposed to be using the mapValue and arrayValue I can see a lot of mentions regarding the value option but I cannot see any examples on how to use the.

Any help would be greatly appreciated.

Answer 1

Payload to your array or map you're generating is incorrect as per the documentation. You need to wrap your actual data (to store) under values key, your final array should be:

["orderName" => ["arrayValue" => ["values" => [["stringValue" => "test"], ["stringValue" => "test123"]]]]]

Similarly your mapValue should be

["orderName" => ["mapValue" => ["fields" => ["field1" => ["stringValue" => "Gbeila Aliu Wahab"]]]]]

Also, you can play with other data mapper via this package.
