Name : Name of the student, Entry box is used to take user input Class : Combobox is used to take user input or selection of student class Gender : Radio buttons for selection of Gender of the student. mark : Entry to accept mark of the student. photo : Blob column to store uploaded any JPG or PNG image
Tkinter GUI to collect user inputs with Photo to store in student Database table with Blob column
There are two parts of this script. In first part we will create the layout and upload - display the student photo. In second part we will insert the details to Database.
We will first display the Tkinter GUI with all input elements.
The function my_upload() to show the file browser and allow uploading of file. After uploading the same image is displayed on the window over a button, showing a sample to the user about the image going to be stored in the database table.
Upload and display image in Tkinter GUI→ Here is the code to upload and display the image within the function.
def my_upload(): # show file browser and preview of photo
global filename,img
f_types = [('All Files', '*.*'),
('JPG', '*.jpg'),
('PNG', '*.png') ]
filename = filedialog.askopenfilename(filetypes=f_types)
img=ImageTk.PhotoImage(file=filename)
b3=tk.Button(my_w,image=img) # display image on this
b3.grid(row=4,column=1,columnspan=3,pady=20)
Above function my_upload() is called when the button b1 is clicked.
The other function my_add() will insert the uesr input data along with the Photo in database table. Details of this function my_add() is covered in Part II of this tutorial.

Run the above code to get the layout with all the inputs the user can use. We can point to any image and check the preview of the photo.
Part II : Storing data in Database
Inserting data with Picture to Blob column of MySQL student table using Tkinter GUI inputs Part II
To create table here is the SQL dump of the student_blob table.
CREATE TABLE IF NOT EXISTS `student_blob` (
`id` int(2) NOT NULL AUTO_INCREMENT,
`name` varchar(50) CHARACTER SET utf8 NOT NULL DEFAULT '',
`class` varchar(10) CHARACTER SET utf8 NOT NULL DEFAULT '',
`mark` int(3) NOT NULL DEFAULT '0',
`gender` varchar(6) CHARACTER SET utf8 NOT NULL DEFAULT 'male',
`photo` blob,
UNIQUE KEY `id` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
Here is the code to connect to MySQL database, enter your MySQL login details and database name here.
from sqlalchemy import create_engine
my_conn = create_engine("mysql+mysqldb://userid:pass@localhost/db_name")
This function my_add() reads the user entered data in Entry element ( name ) user selection of Combobox , radio buttons for gender , mark and the uploaded image. After connecting to MySQL database, it add the data to table.
As a confirmation of data insertion to MySQL table , we use the function lastrowid to get auto-increment id of the record added to the table. This number is displayed in the Message area in our Label l_msg.
def my_add():
global filename
flag_validation=True # set the flag
my_name=e2.get() # read name
my_class=cb1.get() # read class
my_mark=e5.get() # read mark
my_gender=r1_v.get() # read gender
fob=open(filename,'rb') # filename from upload_file()
fob=fob.read() # binary format the image is ready
my_data=(None,my_name,my_class,my_mark,my_gender,fob)
my_query="INSERT INTO student_blob values(%s,%s,%s,%s,%s,%s)"
id=my_conn.execute(my_query,my_data)
l_msg.config(text="id :" + str(id.lastrowid))
print("ID of Row Added = ",id.lastrowid)
Here to keep the code simple and small, the validation part is not included but
same can be added. Here is a list of validation you may consider adding to the script.
The button to add data can be kept as disabled unless some minimum length of text is entered as name and the image file is uploaded. Read how to disable / enable a button here
