Flask: ImmutableMultiDict([]) - Why is it empty? [duplicate]

Question

I'm trying to transfer formdata from html into a database, but when i try to send the content i got an empty Dict.

html looks like this:

...
<form id="set" action="/settings" method="POST">
<h3>Name</h3>
<input type="text" class="input" name="name" id="name" value={{name}}>
<h3>Email</h3>
<input type="text" class="input" name="email" id="email" value={{email}}>
<br><button class="btn" type="submit" form="set">Update</button>
</form>
...

pythoncode looks like this:

...
@app.route("/settings", methods=['POST'])
@login_required
def settings():
    if request.method == 'POST':
        name = request.form['name']
        email = request.form['email']
...

then i got this error:

werkzeug.exceptions.BadRequestKeyError: 400 Bad Request: The browser (or proxy) sent a request that this server could not understand.
KeyError: 'name'

so i printed out the dict

ImmutableMultiDict([])

and saw it was empty. But why? What do i have to change?

Btw i'm using multiple forms in this html, but i dont think this is the problem.

Answer 1

I have found the solution. Sorry, the code above is working. I haven't shared the full code. I have multiple forms in my html and not all input form tags had a name.

wrong:

<input type="text">

correct:

<input type="text" name="pw" id="pw">
