How to use Handlebars in CakePHP?

CakePHP is a popular PHP framework that provides developers with many useful features and tools to help them build web applications more easily. Handlebars is a JavaScript template library that allows you to create reusable templates for dynamically inserting data into web pages. In this article, we will explore how to use Handlebars with CakePHP.

1. Installing Handlebars

First, you need to install Handlebars in your CakePHP application. To do this, you can use Composer to add it as a dependency to your project. Open the application's terminal and run the following command:

composer require phly/mustache

This will automatically download and install Handlebars into your project. You also need to introduce Handlebars in your controller using the following code:

use HandlebarsHandlebars;

2. Create Handlebars Template

Next, you need to create a Handlebars template that will be used to display your data. Create a new file called "template.hbs" and populate it with the following code:

<h1>{{title}}</h1>
<p>{{content}}</p>

This is a simple template that will display two variable values: title and content. These variables will be passed from your controller.

3. Loading data

In your controller you can load the data using the following code:

$data = [
    'title' => 'Welcome to my site',
    'content' => 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.'
];

The data contains two variables: title and content, which will be used in Handlebars templates. You can pass data to the view using the following code:

$this->set(compact('data'));

4. Rendering Template

Next, you need to use Handlebars to render your template and insert the data into it. You can do this using the following code:

$handlebars = new Handlebars();
$template = file_get_contents(APP . 'View' . DS . 'template.hbs');
$output = $handlebars->render($template, $data);
$this->set(compact('output'));

This will render the template using Handlebars and insert the data into it. Finally, you will have a variable called "output" that contains the complete HTML code.

5. Display the output

The last step is to display the output in the view. You can insert HTML code into your page using the following code:

<?= $output ?>

6. Conclusion

Now you know how to use Handlebars in CakePHP to create dynamic templates. Handlebars makes it easy to build reusable templates, which can improve the maintainability and scalability of your application. Try Handlebars on your next project and see how it streamlines your workflow.
