Error: Can not send value to non-payable contract method or constructor

2022-02-04 00:13:11 Q & A of Denglian community

Contract The method of has been set to payable, however web3 Still no hint payable,remix There is no problem with internal interaction , I don't know how to adjust ?

// ------------------------------------------------------------------------    // 1,000,000 UICI Tokens per 1 ETH    // ------------------------------------------------------------------------    function setInfo(string _fName, uint _age) public payable {        fName = _fName;        age = _age;        require(now >= startDate && now <= endDate);        uint tokens;        if (now <= bonusEnds) {            tokens = msg.value * 1200000;        } else {            tokens = msg.value * 1000000;        }        balances[msg.sender] = safeAdd(balances[msg.sender], tokens);        _totalSupply = safeAdd(_totalSupply, tokens);        Transfer(address(0), msg.sender, tokens);        owner.transfer(msg.value);    }    function getInfo() public constant returns (string, uint) {       return (fName, age);   }
