How To Make SignIn Form In Python Using Tkinter With MySQL DataBase
In this Python Tutorial we will see Make A Login Form Using Python Tkinter And MySQL Database.
Source Code:
- Create the Login Form
#login form
import tkinter as tk
from tkinter import messagebox
from py_mainform_2 import mainform
import mysql.connector
# connect with mysql database
connection = mysql.connector.connect(
host='localhost',
user='root',
password='',
port='3306',
database='py_lg_rg_db'
)
c = connection.cursor()
root = tk.Tk()
# create a function to close the window
def close_window():
root.destroy()
# width and height
w = 400
h = 260
class loginForm:
def __init__(self,master):
self.master = master
# start center window
ws = self.master.winfo_screenwidth()
hs = self.master.winfo_screenheight()
x = (ws-w)/2
y = (hs-h)/2
self.master.geometry('%dx%d+%d+%d' % (w, h, x, y))
# end center window
# start create widgets
self.frame = tk.Frame(self.master, bg='#fff')
self.btnsFrame = tk.Frame(self.frame, bg='#fff', padx=40, pady=15)
self.windowTitle = tk.Label(self.frame, text='Login Window', bg='#fff',
fg='blue', font=('Tahoma',20), pady=30)
self.usernameLabel = tk.Label(self.frame, text='Username:', bg='#fff',
font=('Verdana',16))
self.usernameTextbox = tk.Entry(self.frame, font=('Verdana',12), width=25,
borderwidth='2', relief='ridge')
self.passwordLabel = tk.Label(self.frame, text='Password:', bg='#fff',
font=('Verdana',16))
self.passwordTextbox = tk.Entry(self.frame,show='*', font=('Verdana',12),
width=25, borderwidth='2', relief='ridge')
self.btnLogin = tk.Button(self.btnsFrame, text='Login', bg='green',
font=('Verdana',12), fg='#fff', padx=25,
pady=10, command=self.login_func)
self.btnCancel = tk.Button(self.btnsFrame, text='Cancel', bg='orange',
font=('Verdana',12), fg='#fff', padx=25,
pady=10, command=close_window)
# end create widgets
# start place widgets
self.frame.pack(fill='both')
self.windowTitle.grid(row=0, column=0, columnspan=2)
self.usernameLabel.grid(row=1, column=0)
self.usernameTextbox.grid(row=1, column=1)
self.passwordLabel.grid(row=2, column=0, pady=(10,0))
self.passwordTextbox.grid(row=2, column=1, pady=(10,0))
self.btnsFrame.grid(row=3, column=0, columnspan=2, pady=10)
self.btnLogin.grid(row=0, column=0, padx=(0,35))
self.btnCancel.grid(row=0, column=1)
# end place widgets
# create a function to login
def login_func(self):
username = self.usernameTextbox.get()
password = self.passwordTextbox.get()
select_query = 'SELECT * FROM `users` WHERE `username` = %s and password = %s'
vals = (username, password,)
c.execute(select_query, vals)
#print(c.fetchall())
user = c.fetchone()
if user is not None:
#messagebox.showinfo('Login', 'Yes')
mainformwindow = tk.Toplevel()
app = mainform(mainformwindow)
root.withdraw()
mainformwindow.protocol('WM_DELETE_WINDOW', close_window)
else:
messagebox.showwarning('Error', 'Enter a Valid Username & Password')
def main():
login_window = loginForm(root)
root.mainloop()
if __name__ == '__main__':
main()
- Create the Mainform
# main form
import tkinter as tk
from tkinter import *
w = 1200
h = 650
class mainform:
def __init__(self, master):
self.master = master
# ----------- CENTER FORM ------------- #
ws = self.master.winfo_screenwidth()
hs = self.master.winfo_screenheight()
x = (ws-w)/2
y = (hs-h)/2
self.master.geometry("%dx%d+%d+%d" % (w, h, x, y))
self.frame = tk.Frame(self.master)
self.frame.pack()
self.master.config(bg="#2A2C2B")
self.lbl = tk.Label(self.master, text='Main Form', font=('verdana',50, 'bold')
, fg='#ecf0f1',bg="#2A2C2B")
self.lbl.place(rely=0.5, relx=0.5, anchor=CENTER)
