We're having requirement to get failure message from require
validation. I've searched a lot for the same and found that Remix is displaying messages, however web3 is not.
In order to get messages, we have created internal function which returns Boolean result and a string message.
function validateDoc(
bytes32 _a,
string _b,
uint256 _c
) internal view
returns(bool, string){
if(condition 1){
return(false, "failure message1");
}else if(condition 2){
return(false, "failure message2");
}
}else if(condition 3){
return(false, "failure message3");
}
}else if(condition 4){
return(false, "failure message4");
}
}
Further, I'm calling it from another function:
function Main(
bytes32 _a,
string _b,
uint256 _c
) public returns(bool, string) {
validateDoc(_a, _b, _c); // TODO: return bool result and message.
// Other code
// ...
return (true, "success message");
}
But the issue is, how to return both result of validateDoc
in Main
function?
