Node.js: Upload large file to MongoDB AND data from text inputs on the same page to different collections
Actually when using multer, the text-fields from your form should still be populated under req.body.<field-name>, so you should be able to just use your initial code for inserting the tour-data:
app.post("/office/add-score", upload.single("file"), (req, res) => { const addedTour = new Tour({ tour: { tourHeading: req.body.tourHeading, tourDescription: req.body.tourDescription, }, program: { tourProgram: req.body.tourProgram, tourProgramDescription: req.body.tourProgramDescription, } }); addedTour.save(...)});
