How to use TCPDF with CakePHP?

CakePHP is a very popular PHP framework that provides many convenient methods for web application development. TCPDF is a very commonly used PDF generation library when we need to generate PDF files in applications. This article will introduce how to use TCPDF in CakePHP.

1. Installing TCPDF

First, we need to install TCPDF in our CakePHP project. This can be done in several ways, such as manually copying TCPDF into the project's vendor folder, or using Composer to install TCPDF.

If you want to use Composer to install TCPDF, you only need to run the following command in the root directory of the project:

composer require tecnickcom/tcpdf

Then, Composer will automatically download and install TCPDF for you.

2. Create a TCPDF view file

Once we have installed TCPDF, we can create a TCPDF view file. This view file will be used to generate PDF files. In our CakePHP application, we can create a tcpdf.ctp file in the app/View/Tcpdf/ directory. The file name can be anything you want.

In this file, we need to instantiate TCPDF and set some basic PDF properties, such as page orientation, page size, left, right, top and bottom margins, etc.

For example, here is a very basic tcpdf.ctp file:

<?php

// Set the page orientation and size, and the page margins
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false); PDF PAGE FORMAT, true, 'UTF-8', false); $pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('Your Name');
$pdf->SetTitle('Your PDF Title');
$pdf->SetSubject('Your PDF Subject');
$pdf->SetKeywords('your, keywords, here');
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);

// Add a page
$pdf->AddPage();

// Output the PDF
$pdf->Output('example_001.pdf', 'D');

In this example, we set the page orientation and size, and set the margins for one page. We then added a page and downloaded the PDF file to the browser.

2. Create PDF Controller

Now we need to create a Controller to render the TCPDF view. We can create a PdfController.php file in the app/Controller/ directory. In this file, we need to load the TCPDF library in the beforeFilter() method.

For example, the following is the code we can use in the PdfController.php file:

<?php

App::import('Vendor', 'tcpdf/tcpdf');
class PdfController extends AppController {

    public function beforeFilter() {
        parent::beforeFilter();
        $this->autoRender = false;
        $this->layout = false;
    }

    public function index() {
        $this->render('/Pdf/tcpdf');
    }

}

In this code, we import the TCPDF library into our Controller, and in the beforeFilter() method Turn off automatic rendering and layout in .

Then, we created a method called index() that will render our TCPDF view file (in the app/View/Tcpdf/ directory).

3. Access the PDF page

Finally, we need to access our PDF generation page through the browser to generate the PDF file. We can complete this process by accessing the following page address: http://yourdomain.com/pdf/index.

Once we access the PDF page, we can see the generated PDF file and can download it to our local computer. We can also generate more complex PDF files by modifying the tcpdf.ctp file.

Summary:

In this article, we learned how to use TCPDF to generate PDF files in CakePHP. We have to install TCPDF library and create a TCPDF view file.

Then, we need to create a Controller to render our TCPDF view file. Finally, by accessing the PDF page, we can display our PDF files to users as browser downloads.

Through this article, you learned how to use TCPDF in a CakePHP application to generate PDF files. This can provide additional functionality to your application and provide your users with some great features and experiences.
