How to Import CSV Data into Custom Content Types (CCTs) Using WordPress and JetEngine

When managing a business, importing data from CSV files is a powerful way to save time and avoid manual input errors. In this tutorial, we’ll explore how to import CSV files into Custom Content Types (CCTs) using WordPress and the JetEngine plugin.

This guide assumes basic knowledge of WordPress, PHP, and database management. We’ll break down the process of creating a function to import customer data (like names and email addresses) from a CSV file into the "Customers" CCT.

Understanding CCTs and JetEngine

CCTs (Custom Content Types) in JetEngine provide a more flexible and efficient way to store data compared to Custom Post Types (CPTs). Unlike CPTs, CCTs don’t use the WordPress post table but instead rely on custom database tables. This makes them ideal for handling large datasets or complex relationships.

Goal of the Tutorial

We will create a WordPress shortcode that allows users to upload a CSV file via the front end. The script will read this file, validate the data, and insert it into the CCT’s database table. The focus will be on importing customers' names and emails into the cliente_cct CCT, with the database table wp_jet_cct_cliente_cct.
