Installation
-------------------------------------
0) You need to install Composer first, if you already installed you can skip this step.
1) Open your working folder, if you are using xammpp you need to open htdocs directory.
2) Now open CMD and go to htdocs folder, and run the composer command given below.
composer create-project codeigniter4/appstarter ci4_crud
Note: make sure intl and mbstring extension installed.
3) To access the project in browser, we need top open ci4_crud in CMD and run the command given below.
php spark serve
If, you see a welcome screen it means, you have successfully installed Codeigniter 4 project.
4) Create a database called ci4_latest with a table called "books", that we will use in our CRUD application
id, title, isbn_no, author, created_at
5) Create a controller called "Book" inside the following directory.
app\controllers\Book.php
6) Now inside "Book" controller, we'll create a method called "index". This method will load our
first landing page, which will hold the listing of books in a tabular form.
7) Open routes.php and create a "Get" route for books listing.
8) We will use bootstrap 4 for our project, you can download bootstrap files from my github account.

9) Create a folder name "assets" inside public directory and paste the "css" and "js" folder there.
10) Now, we will create a view called "list.php" inside sub folder called "books" in views
directory, directory given below.
app\views\books\list.php
11) Let's load our "list.php" view in "index" method of Book Controller class and create some basic
structure for our CRUD APP in our "list.php" view.
############# Create
12) Now we'll create function in "Book Controller" that will load our create form
Location: app\Controllers\Book.php
13) Now in routes.php file we need to define a get route.
14) Let's create a view called "create.php" in the location given below. And load this view in in
create method of "Book Controller"
Location: Views/books/create.php
15) Lets create our create form inside "create.php" view.
16) In "create" method of "Book" Controller, we'll validate our form, and then save values in DB.
17) Before save we need to create a model which will interact with database and save values in DB,
we will create a model called "BookModel.php" in following location.
App\Models\BookModel.php
Note: Make sure define allowed fields in model
protected $allowedFields = ['title','isbn_no','author'];
19) Now after save we will redirect user with a flash session message
Winner Winner Chicken Dinner, you have successfully completed create part.
