NOT IN RANGE exception for smart contract call that returns many values.

NOT IN RANGE exception for smart contract call that returns many values.

[digitaldonkey]

uint[] is not supported the library yet. I consider to add https://github.com/sc0Vu/rlp but I need to do some Drupal work first.

[danielefavi]

Without uint[] I'm getting the exception
Call to a member function convertByAbi() on integer
raised by the function getMethodParams($m, $values) of the file SmartContract.php on line 138
$validAbiType = $val->convertByAbi($expectedType);

This is the new declaration of the function getProductById on the smart contract:

function getProductById(uint id) public view
returns (
    uint,
    string,
    bytes32,
    uint,
    uint,
    bool
) {
    ...
}

I would like to know if this exception is related to this issue.
Thank you

"Call to a member function convertByAbi() on integer" means that the integer is not a Instance of EthD.

Your calls should look similar to

$contract->getProductById(new EthQ($yourInt))

The call you mentioned gives me again the exception
NOT IN RANGE: 1277465586268147 ... ... ... 887421292544000 > (u)int256

Instead, it works with smart contract functions that returns one value only. For example this is the function on the smart contract side:
function getProductName(uint id) public view returns (string) { ... }

and, in this case, the following call works correctly

$prdName = $instance->getProductName(new EthQ(123));

I didn't get if I don't use properly your library or the feature with multiple values in return is not supported.

Hi,
What syntax should be used for receiving outbound parameters?

function getProductById(uint32 id) public view
returns (
    uint,
    string,
    bytes32,
    uint,
    uint,
    bool
)

To call above function I'm using:

$result = $schemaContract->getProductById(new EthQ($number, ['abi'=>'uint32']));

But 'left' part ($result) is wrong because function getProductById returns many parameters.

Can you help me how above syntax should looks like to get many outbound parameters?
Is it possible with your library or it is not supported yet?
Thx

As far as I understand without actual testing you are returning a list value, which is not supported yet.
You might add your contract and some test to the test contracts.

Let's get some test Data from https://ethereum.stackexchange.com/a/681/852

Should work now, but needs more testing.
