Simple example of using a RadioField in Flask-WTForms to generate a form.

example.html

<form method="post">
    {{ form.hidden_tag() }}
    {{ form.example }}
    <input type="submit">
</form>

siecje.py

from flask import Flask, render_template
from flask.ext.wtf import Form, RadioField

SECRET_KEY = 'development'

app = Flask(__name__)
app.config.from_object(__name__)
class SimpleForm(Form):
    example = RadioField('Label', choices=[('value','description'),('value_two','whatever')])


@app.route('/',methods=['post','get'])
def hello_world():
    form = SimpleForm()
    if form.validate_on_submit():
        print form.example.data
    else:
        print form.errors
    return render_template('example.html',form=form)

if __name__ == '__main__':
    app.run(debug=True)

nice, I have been looking for this

Great !!!

What I need clear:

1. I have form "role.html" and I am using :

{{ wtf.form_field(form.jobtitle, placeholder='Job Title', size=10 ) }}

{{ wtf.form_field(form.jobtype) }}

{{ wtf.form_field(form.companytype) }}

{{ wtf.form_field(form.companyculture) }}

To generate.

Now, when I will enter the values accordingly, how can I show them on webpage (on label) ?

Kindly guide, as I am trying to learn Python/Flask

This is how it worked for me under python 3.

from flask import Flask, render_template
from wtforms import Form, RadioField

SECRET_KEY = 'development'

app = Flask(__name__)
app.config.from_object(__name__)


class SimpleForm(Form):
    example = RadioField(
        'Label', choices=[('value', 'description'), ('value_two', 'whatever')])


@app.route('/', methods=['post', 'get'])
def hello_world():
    form = SimpleForm()
    if form.validate():
        print(form.example.data)
    else:
        print(form.errors)
    return render_template('example.html', form=form)


if __name__ == '__main__':
    app.run(debug=True)

I also needed to remove the hidden_tag() from the form, since I get the error message: object has no attribute 'hidden_tag'.

<form method="post">
  {{ form.example }}
    <input type="submit">
</form>

This was what I had to do to get it working on Python 3 using FlaskForm

from flask import Flask, render_template
from flask_wtf import FlaskForm
from wtforms import RadioField


SECRET_KEY = 'development'


app = Flask(__name__)
app.config.from_object(__name__)
class SimpleForm(FlaskForm):
    example = RadioField('Label', choices=[
        (1,'description'), (2,'whatever')],
        default=1, coerce=int)


@app.route('/',methods=['post','get'])
def hello_world():
    form = SimpleForm()
    if form.validate_on_submit():
        print(form.example.data)
    else:
        print(form.errors)
    return render_template('example.html',form=form)


if __name__ == '__main__':
    app.run(debug=True)

this works

how to validate the radiobutton

how to make the options side by side, like this:

• option 1 *option 2 *option3 * option4 ...

how to validate the radiobutton

from wtforms.validators import InputRequired

example = RadioField('Label', choices=[
        (1,'description'), (2,'whatever')],
        default=1, coerce=int, validators=[InputRequired()])
