How to Retrieve and Store Multidimensional Array Data in CodeIgniter 3

In modern web applications, it's common to deal with forms that pass multidimensional array data. For instance, you may have multiple addresses entered by a user, where each address has a street and a city. If you are using CodeIgniter 3, you may encounter challenges when trying to retrieve and store this structured data in your database.

The Problem

Suppose you created a form that allows users to input addresses as follows:

Additional Note

Make sure your database table is structured to accept these fields (e.g., street and city).

Conclusion

Retrieving and storing multidimensional array data in CodeIgniter 3 is straightforward once you understand how to access the data effectively. By following the steps outlined above, you can ensure that your application works efficiently, regardless of the complexity of the form data.

By structuring your data retrieval properly, you not only simplify your code but also lay the groundwork for effective data management in your applications.
