这个放在前面你个表单的博客内容

精髓放这

                            RadioField, IntegerField, DecimalField, SubmitField)
from wtforms.validators import DataRequired, InputRequired, Length, Email, EqualTo, NumberRange

class WtfForm(FlaskForm):
    # StringField 文本输入框,必填,用户名长度为4到25之间,占位符
    username = StringField('用户名:', validators=[Length(min=4, max=25)], render_kw={'placeholder': '请输入用户名'})

    # RadioField,单选框,choices里的内容会在ul标签里,里面每个项是(值,显示名)对
    gender = RadioField('性别:', choices=[('0', '男'), ('1', '女')], validators=[DataRequired()])

    # SelectField,下拉单选框,choices里的内容会在Option里,里面每个项是(值,显示名)对

@app.route('/login', methods=['GET', 'POST'])
def login():
    form = WtfForm()
    if request.method == 'POST':
        # 获取form表单提交过来的值
        username = form.username.data
        pwd = form.password.data
        print(username, pwd, sep='====')
    return render_template('wtf.html', form=form)



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


用的时候备查

需要注意的是如果EMAIL位置的报错那么你需要加载一个库

这样基本可以解决。然后是。。。。

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<form action="{{ url_for('login') }}" method="post">
    {{ form.csrf_token }}
    {{ form.username.label }}{{ form.username }}
    <br>
    {{ form.email.label }}{{ form.email }}
    <br>
    {{ form.password.label }}{{ form.password }}
    <br>
    {{ form.password2.label }}{{ form.password2 }}
    <br>
    {{ form.age.label }}{{ form.age }}
    <br>
    {{ form.height.label }}{{ form.height }}
    <br>
    {{ form.birthday.label }}{{ form.birthday }}
    <hr>
    {{ form.gender.label }}{{ form.gender }}
    <br>
    {{ form.job.label }}{{ form.job }}
    <br>
    {{ form.hobby.label }}{{ form.hobby }}
    <br>
    {{ form.description.label }}{{ form.description }}
    <br>
    {{ form.accept_terms.label }}{{ form.accept_terms }}
    <br>
    {{ form.submit }}
    <br>

</form>
</body>
</html>

如果需要将WFT与bootstrap进行联合渲染使用,那么参考这个 传送门
