{{form.csrf_token}}
</form>
from flask import Flask,request,make_response,render_template,redirect
from flask_wtf import FlaskForm
from wtforms import *
from wtforms.validators import DataRequired
app = Flask(__name__)
app.secret_key=b'\x97\x91\xde\xc3dlP\xdf\xe49;\x9cn\xc5\xd2\xb0\x0e\xfd\x8f\xbd\x867b\xe6'

from wtforms import *
from wtforms.validators import DataRequired
app = Flask(__name__)
app.secret_key=b'\x97\x91\xde\xc3dlP\xdf\xe49;\x9cn\xc5\xd2\xb0\x0e\xfd\x8f\xbd\x867b\xe6'
class MyForm(FlaskForm):
name = StringField('name', validators=[DataRequired('这个字段必填')])
is_fav = BooleanField(label='推荐')
my_file= FileField(label='图片')
info = TextField(label='简介')
pwd = PasswordField(label='密码')
ta = TextAreaField(label='富文本框')
roles = SelectField(choices=[(1,'admin'),(2,'teacher'),(3,'student')])
auths = SelectMultipleField(choices=[(1,'admin'),(2,'teacher')])
submit = SubmitField(label='提交')
@app.route('/sucess')
def sucess():
return '提交成功'
@app.route('/submit',methods=('GET','POST'))
def submit():
form = MyForm()
if form.validate_on_submit():
return redirect('/sucess')
return render_template('submit2.html',form=form)四、表单样式
使用bootstrap表单样式
1.render_kw
from flask import Flask,request,make_response,render_template,redirect
from flask_wtf import FlaskForm
from wtforms import *
from wtforms.validators import DataRequired
app = Flask(__name__)
app.secret_key=b'\x97\x91\xde\xc3dlP\xdf\xe49;\x9cn\xc5\xd2\xb0\x0e\xfd\x8f\xbd\x867b\xe6'
class MyForm(FlaskForm):
name = StringField('name', validators=[DataRequired('这个字段必填')],render_kw={'class':'form-contral'})
is_fav = BooleanField(label='推荐')
my_file= FileField(label='图片')
info = TextField(label='简介',render_kw={'class':'form-contral'})
pwd = PasswordField(label='密码',render_kw={'class':'form-contral'})
ta = TextAreaField(label='富文本框',render_kw={'class':'form-contral'})
roles = SelectField(choices=[(1,'admin'),(2,'teacher'),(3,'student')])
auths = SelectMultipleField(choices=[(1,'admin'),(2,'teacher')])
submit = SubmitField(label='提交',render_kw={'class':'btn btn-default'})
@app.route('/sucess')
def sucess():
return '提交成功'
@app.route('/submit',methods=('GET','POST'))
def submit():
form = MyForm()
if form.validate_on_submit():
return redirect('/sucess')
return render_template('submit2.html',form=form)<!DOCTYPE html>

<meta charset="UTF-8">
