CodeIgniter 4 CRUD Series with MySQL
This post is a re-share of an article I originally published on my Medium account and is part 3 in the CodeIgniter 4 CRUD with MySQL series. Be sure and visit the 2 previous blog posts to get up to speed.
CodeIgniter 4, like most frameworks, provides an ORM (or something comparable) to help ease the pain of working with databases (if that is in fact, pain for you 😁). In CodeIgniter’s case, there are the Model and Query Builder classes
CodeIgniter 4 Model update() method
The CodeIgniter Model class has CRUD methods built right in and they are super-easy to employ for those standard CRUD operations. The model update() method accepts 2 parameters for UPDATE operations: the primary key id for the target row to be updated, and an associative array of data with key/value pairs matching the tables’ columns.
Learn more about the update() method and see examples in the post, CodeIgniter 4 CRUD Series with MySQL: Update.
