Tips for accessing req.fields variables while utilizing Express-Formidable

For some reason, I am encountering difficulties when trying to access variables parsed within req.fields using Express-Formidable. Upon executing a console.log() of req.fields, the output is as follows:

{ 'registration[username]': '1', 
'registration[password]': '11' }

Despite this, I am unable to specifically access the username or password field. Various attempts have been made, including:

console.log(req.fields.registration.username)
console.log(req.fields.registration[username])
console.log(req.fields.registration['username'])
console.log(req.fields.username)

Any assistance on this matter would be greatly appreciated. Thank you!

Working with keys enclosed in square brackets can be a bit cumbersome, but fear not as you can still retrieve the values by treating them as strings.

Instead of using req.fields.keyName, opt for the alternative square bracket notation like so: req.fields[keyName].

There are two primary methods to achieve this:

Method A - Utilizing predefined key names

// Assume the key remains consistent
const emailKey = 'form[contactEmail]'

// Grab the value using this key
const emailValue = req.fields[emailKey]

Method B - Dynamically extract and utilize the keys

const allKeys = Object.keys(req.fields)

allKeys.forEach(key => {
  console.log(req.fields[key])
})

While Method B may present challenges in distinguishing individual values, it allows for extraction nonetheless.

Best of luck on your coding journey!
