Setting up an Api

You can create a plugin, e.g. "Api" to include all your API controller code. If you have an Api plugin, make sure you set 'bootstrap' => true when loading the plugin in your bootstrap.

To make sure we always return errors in the api as JSON, include this to your App's or Plugin's bootstrap.php:

if (substr(env('REQUEST_URI'), 0, 5) === '/api/') {
    $errorHandler = new \CkTools\Error\ApiErrorHandler([
        'exceptionRenderer' => '\CkTools\Error\ApiExceptionRenderer'
    ]);
    $errorHandler->register();
}

Load the ApiComponent in your AppController's initialize() callback:

$this->loadComponent('RequestHandler');
$this->loadComponent('CkTools.Api');

In your AppController's beforeFilter() callback call

$this->Api->setup();

In a controller, your API endpoint controller action could look like this:

public function hello_world()
{
    $this->request->allowMethod('get');
    return $this->Api->response(200, ApiReturnCode::SUCCESS, [
        'hello' => 'world'
    ]);
}

This call will return an application/json response with the HTTP Status Code 200 and the following body:

{"code": "success","data":{"hello":"world"}}

Create a PDF using CakePHP Views

CkTools includes a simple wrapper for the MPDF (http://www.mpdf1.com/mpdf/index.php) library.

Usage (in this example in the controller, but you can use this wherever you want):

use CkTools\Lib\PdfGenerator;

$pdfGenerator = new PdfGenerator([
    'pdfSourceFile' => '/path/to/your/template.pdf' // optional
]);
$pdfGenerator->render('my_element', [
    'viewVars' => [
        'foo' => 'bar'
    ],
    'target' => PdfGenerator::TARGET_BROWSER,
    'cssFile' => '/path/to/your/styles.css',
    'cssStyles' => 'body { font-size: 20px }'
]);

In Template/Element/my_element.ctp you have the passed viewVars and the $mpdf variable for manipulating the PDF.

<?php $this->start('my_block') ?>
    <div class="foo"><?= $foo ?></div> 
<?php $this->end() ?>

<?php
$mpdf->SetHeader('My Document Title');
$mpdf->Bookmark('Start of the document');
$mpdf->WriteHTML($this->fetch('my_block'));

// Add a new page
$mpdf->AddPage();
$mpdf->WriteHTML("This is page 2");
?>
