and this is my backend code
Orders.patch([ Object.assign({id: req.params.id}, req.body) ])
.then(orders => {
DB.query("SELECT oauth FROM users WHERE id = "+req.body.driver+" OR id = "+req.body.customer+"").then(res=>{
res.map((row,i)=>{
let tmp = {
token: row.oauth.token
}
res[i] = tmp;
});
// console.log(res);
const arrayToken = res.map(function (obj) {
return obj.token;
});
// console.log(arrayToken);
const message = {
// to: res[0].token,
registration_ids: arrayToken,
notification: {
body: "Hey! you got update order notification."
}
};
fcm.send(message, function(err, response){
console.log(response);
})
}).catch(err => console.log(err));
jsonData = util.jsonData(null, orders);
res.json(jsonData);
})
.catch(err => {
jsonData = util.jsonData(400);
res.status(jsonData.code).json(jsonData);
})
})
So how to fixed it and can you help me explain error of my code ?

Answer 1

Error is here
WHERE id = "+req.body.driver+" OR id = "+req.body.customer+"
You need to use defined variables in this scope
