'How to insert an array with some repeating values into mysql using node.js
I'm trying to insert and values into my database and I thought having the same name for the inputs in my form would make it easier for me to insert them in bulk, I want to iterate OrderNo and quantity and insert them to a new column while keeping the other inputs such as fname the same until the values in OrderNo are done.
app.post("/send-data", (req,res)=>{
let sql = "INSERT INTO foodorder.orders (" +
"food_id," +
" qty,"+
" customer_FName," +
" customer_LName," +
" customer_number," +
" customer_email," +
" customer_facebook," +
" order_date," +
" delivery_option," +
" mode_of_payment," +
" delivery_time" +
") VALUES (" +
` ${req.body.OrderNo},` +
` ${req.body.quantity},` +
` "${req.body.fname}",` +
` "${req.body.lname}",` +
` "${req.body.Contact}",` +
` "${req.body.email}",` +
` "${req.body.facebook}",` +
` "${req.body.date}",` +
` "${req.body.delivery}",` +
` "${req.body.payment}",` +
`"${req.body.time}"` +
`)`;
con.query(sql, (err,result) => {
if(!err){
res.send(result);
}
else{
res.json(req.body);
throw err;
}
})
});
This is the code that I have and currently it only accepts 1 OrderNo and quantity and when I try to order many products with different quantities it will say column count doesn't match value count at row 1 (see attached photo below)
[the output i get from my forms *I didnt include in the screenshot the other output details such as email etc.][1]
is there a way to just iterate the OrderNo and quantity and insert them creating new columns but with the same fname and lname etc.? or do i need to use MySql cursor?
Note that my code works and inserts if i only have selected 1 order and 1 quantity in my forms
UPDATE
Attached here is what I wanna achieve. I wanna know a way to iterate or loop the OrderNo and quantity and insert them into their respective columns while keeping the other values the same like fname and lname.

Fixed by iterating the OrderNo. Thanks so much Diogo
