There are a few unanswered questions here on SO about this WTForms feature. There seems to be no documentation covering the uniqueness between this and FileField. Does anyone have a working example for how to upload multiple files and access them all in python?
class RegistrationForm(FlaskForm):
username = StringField('Username', validators=[validators.Length(min=4, max=25), validators.DataRequired()])
password = PasswordField('Password', [validators.DataRequired()])
packets = MultipleFileField('Upload filesT')
@app.route('/', methods=['GET', 'POST'])
def index():
form = forms.RegistrationForm()
if request.method == 'POST':
# Junk code for sake of exploration.
if form.packets.data:
print("files")
print(form.packets.data)
for file in form.packets.data:
print(file)
packet_filenames = secure_filename(form.packets.data)
else:
print("no files")
