How to Get All Entry Box Values and Insert into SQLite3 in Python Tkinter

Working with user inputs in GUI applications is common, especially when you're developing with Python's Tkinter library. A typical scenario involves creating multiple entry boxes where users can input data, which you then want to store in a database, such as SQLite3. In this guide, we will explore how to retrieve values from these entry boxes and insert all of them into SQLite3 efficiently.

The Problem at Hand

Many developers face the issue of retrieving values from multiple Tkinter entry boxes and inserting them into a database. In one scenario, a user has created multiple entry boxes dynamically but found that only the last three entries were being saved into the SQLite3 database. This likely resulted from the way the entries were being accessed and stored.

Here's a quick recap of the steps the original code implemented before we dive into the solution:

Create a Tkinter GUI with dynamic entry boxes.

Insert values from a few selected entry boxes into an SQLite3 database.

However, the goal here is to ensure that we save the values from all entry boxes instead of just the last few.

Solution Steps

To achieve the desired functionality, we will make some adjustments to the code. Below are the modified components of the solution:

Step 1: Use a List to Store Entry Values

The existing code uses a list called self.all_entries to store references to all entry box groups. This allows us to collect all values when needed.

Step 2: Modify the Save Function

Here’s the key modification in the save() function. Instead of inserting values from only the most recent entries, we will loop through all entry sets stored in self.all_entries.

Updated Code Example

Here’s a snippet demonstrating how to implement these changes:

Step 3: Retrieve and Display Entries

Ensure you have a method to display the entries correctly:

Here, you retrieve and print the values of all boxes, enabling you to validate what’s being stored in SQLite.

Step 4: Dynamic Entry Box Creation

Your addBox() function creates new entry boxes dynamically:

Conclusion

By adopting these modifications, you can efficiently retrieve values from all entry boxes in your Tkinter application and insert them into an SQLite database. This not only enhances the functionality of your application but also improves its user experience by allowing users to input vast amounts of data easily.

With this guide, you now have a clear understanding of how to handle multiple entry boxes with Tkinter and save data into SQLite3 seamlessly. Happy coding!
