Feedback Form
Introduction
In this post I'll show you the code for a feedback form which when someone fills it in, it sends the feedback to your email. It also has a feature that it adds a cookie to the device so you can only fill in the form once an hour.
Structure
Your files and folder needs to be structured like below:
-- main.py
-- app.py
-- functions.py
-- templates
|__ index.html
-- .env
Code
main.py
from app import app
if __name__ == "__main__":
app.run(host="0.0.0.0", port=8080)
app.py
from flask import Flask, render_template, redirect, request
from functions import send_mail, getcookie, addcookie, delcookies
import datetime
import os
import pytz
app = Flask(__name__, template_folder="templates")
app.config["SECRET_KEY"] = os.getenv("SECRET_KEY")
utc = pytz.UTC
@app.route("/")
def index():
return render_template("index.html")
@app.route("/submitform", methods=["POST", "GET"])
def submitform():
if request.method == "POST":
lastdone = getcookie("lastdone")
if lastdone != False:
timenow = datetime.datetime.now()
lastdone = lastdone.replace(tzinfo=utc)
timenow = timenow.replace(tzinfo=utc)
onehour = datetime.timedelta(hours=1)
lastdone = lastdone + onehour
if lastdone > timenow:
return "You can do the form at most once every hour!"
delcookies()
title = request.form["title"]
email = request.form["email"]
description = request.form["description"]
send_mail(title, email, description)
addcookie("lastdone", datetime.datetime.now())
return "done!"
else:
return redirect("/")
functions.py
import os
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
import smtplib
import ssl
from flask import session
def send_mail(title, email, description):
context = ssl.create_default_context()
MAILPASS = os.getenv("MAIL_PASSWORD")
MAIL = os.getenv("MAIL")
html = f"""
<h1>{title}</h1>
<p>{description}</p>
<p>From {email}</p>
"""
message = MIMEMultipart("alternative")
message["Subject"] = "Feedback Form"
part2 = MIMEText(html, "html")
message.attach(part2)
try:
sendermail = MAIL
password = MAILPASS
gmail_server = smtplib.SMTP('smtp.gmail.com', 587)
gmail_server.starttls(context=context)
gmail_server.login(sendermail, password)
message["From"] = sendermail
message["To"] = sendermail
gmail_server.sendmail(sendermail, sendermail, message.as_string())
return True
except:
return "Verification email not sent, due to some issues."
gmail_server.quit()
def addcookie(key, value):
session[key] = value
def delcookies():
session.clear()
def getcookie(key):
try:
if (x := session.get(key)):
return x
else:
return False

return False
templates/index.html
<!DOCTYPE html>
<html lang="en-GB">

<body>
<h1>Feedback Form</h1>
<form method="POST" action="/submitform">
<input placeholder="title" name="title" autocomplete="off" required><br>
<input type="email" placeholder="email" name="email" autocomplete="off" required><br>
<textarea name="description" rows="4" cols="50" placeholder="description">
</textarea>
<button class="login-form-button">submit</button>
</form>
</body>
</html>
.env
Before this code will work properly, you have to replace [mail] with the mail you want to receive the emails on, replace [password] with that mail's password, and replace [secret_key] with the secret key you want your Flask app to have.
MAIL=[mail]
MAIL_PASSWORD=[password]
SECRET_KEY=[secret_key]
Conclusion
After putting all of this code together, you will have a fully functional feedback form!
