Basic Example - Part 1
To clearly illustrate the purpose and functionality of the File Asset Manager, it is beneficial to examine a practical example. This section will guide through a straightforward example using the 'welcome' module that's included with all Trongate framework installations. The objective is to store a JavaScript file within the 'welcome' module and display a simple webpage that executes the module's internal JavaScript file.
The Starting Point
A fresh installation of a Trongate web application includes a module named 'welcome', which contains a controller file named Welcome.php. The 'Welcome' controller file comprises a class with a single method, as illustrated below:
<?php
class Welcome extends Trongate {
function index() {
$this->view("welcome");
}
}
The precise code contained within the 'Welcome' controller file will differ from the example shown. For brevity, elements such as access modifiers (e.g., public/private/protected), type hinting, return types, and doc blocks have been omitted.
Adding a New Method
Next, a new method will be added to the controller file. This method, named 'hello', will load a simple view file displaying the message 'hello world'. The updated controller code is as follows:
<?php
class Welcome extends Trongate {
function index() {
$this->view("welcome");
}
function hello() {
$this->view("hello");
}
}
A Simple View File
Proceed by creating a view file containing basic HTML. The code sample below demonstrates a simple HTML template with the message 'Hello World' encapsulated within <h1> tags.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<h1>Hello World</h1>
</body>
</html>
Displaying Content
To verify, open a web browser and navigate to the application homepage, followed by welcome/hello. The 'Hello World' message should be displayed on the screen.
