CakePHP 4 Installation

To create a CakePHP project, run this command into your shell or terminal. Make sure composer should be installed in your system.

$ composer create-project --prefer-dist cakephp/app:~4.0 mycakephp

Above command will creates a project with the name called mycakephp.


Load JS (Javascript) Files

Suppose you have a layout called app.php inside /templates/layout folder. In this layout we will see how to add js files.

Using Html script Tag

Here, we will use script tag of HTML to add Js file links.

<html>

<head>
    <title>Welcome to CakePHP 4 Application</title>
</head>

<body>
  ...  
  
  <script src="/js/jquery.min.js"></script>
  <script src="/js/bootstrap.min.js"></script>
</body>

</html>

Using URL Helper To Create Js Links

This method will create links of Js files with application URL.

<html>

<head>
    <title>Welcome to CakePHP 4 Application</title>
</head>

<body>
  ... 
  
  <script src="<?= $this->Url->build('/js/jquery.min.js', ['fullBase' => true]) ?>"></script>
  <script src="<?= $this->Url->build('/js/bootstrap.min.js', ['fullBase' => true]) ?>"></script>
</body>

</html>

Using HTML helper

We will use script() method of HTML helper to link Js files. We can load either row by row or we can load multiple Js files at once.

You can add .js with file name or not. It is optional to use inside script() method. If you add only file name then method will add .js automatically with it.

Load Js file step by step:

<html>

<head>
    <title>Welcome to CakePHP 4 Application</title>
</head>

<body>
  ... 
  
  <?php echo $this->Html->script("jquery.min.js"); ?>
  <?php echo $this->Html->script("bootstrap.min.js"); ?>
</body>

</html>

script() method picks file from /webroot/js directory. So don’t need to pass folder path here. If you have your js files into some different folder then you need to specify.

Load all Js files at once:

<html>

<head>
  <title>Welcome to CakePHP 4 Application</title>  
</head>

<body>
    ...
  
    <?php echo $this->Html->script([
        "jquery.min.js",
        "bootstrap.min.js"
    ]); ?>
</body>

</html>
