I have created a contract with functions...the get() is used for storing and getarray is for returning values...

struct arrayy{
    uint256[] arrayvalue;
}
mapping(address => arrayy) arraymapping;

event logg(
    uint256 z,
    address sender
);

function get(uint256 y, address _owner) internal{
   arraymapping[_owner].arrayvalue.push(y);
   emit logg(y,_owner);
}

function getarray(address _owner) internal returns(uint256[]){

    return(arraymapping[_owner].arrayvalue);
}

Then I deployed the contract, and tried to call the get() function by using...

DeployedContractAddress.call(bytes4(keccak256("get(uint256,address)")),1234,0xfffff);

The value is stored because, When I tried to call the getarray() function the value is returned...

But the emit() is not working...

Why this emit() is not working? Help me to resolve this issue? Help will be appreciated...

As pr your code I can see there is a issue in access specifier. There is no issue in emit()

function get(uint256 y, address _owner) internal{
   arraymapping[_owner].arrayvalue.push(y);
   emit logg(y,_owner);
}

As per solidity document, you can invoke/call internal method's with in the contract and child contract. You can't access out side your contract.

Instead of internal use public or external, so that you can access outside of contract.

function get(uint256 y, address _owner) public{
   arraymapping[_owner].arrayvalue.push(y);
   emit logg(y,_owner);
}

    Yes I changed the code....But when I tried to call the function...uisng below equation... DeployedContractAddress.call(bytes4(keccak256("get(uint256,address)")),1234,0xfffff); still the log is not getting...

  • Same issue for me...When using DeployedContractAddress.call(bytes4(keccak256("get(uint256,address)")),1234,0xfffff); logs are not displayed. ie; when function is called by deployed address, logs are displayed. But when I tried to call function from other wallet address,its not working...Is it not possible?
