How to use tcpdf in Codeigniter?

@lottie 

To use TCPDF in Codeigniter, you can follow these steps:

1. Download and extract the TCPDF library from the official website (https://www.tcpdf.org/).
2. Place the extracted TCPDF folder inside the application/libraries folder of your Codeigniter project.
3. In your controller, load the TCPDF library using the $this->load->library() method. For example:

1

$this->load->library('tcpdf');

1. Create a new PDF document using the TCPDF() constructor. You can pass the page size, orientation and other parameters as arguments to the constructor. For example:

1

$pdf = new TCPDF('P', 'mm', 'A4', true, 'UTF-8', false);

1. Set the document properties using the SetTitle(), SetAuthor() and SetSubject() methods. For example:

1
2
3

$pdf->SetTitle('My PDF Document');
$pdf->SetAuthor('John Doe');
$pdf->SetSubject('PDF with TCPDF in Codeigniter');

1. Add content to the PDF using the various methods provided by TCPDF, such as AddPage(), WriteHTML(), Cell(), Multicell(), etc.
2. Output the PDF to the browser or save it to a file using the Output() method. For example:

1

$pdf->Output('my_pdf_document.pdf', 'I');

This will output the PDF to the browser. You can also use the F option to save the PDF to a file on the server.

I hope this helps! Let me know if you have any questions.

Step 3: Configuring the Autoloader

    public function generate_pdf() {
        // Example usage of TCPDF_wrapper class
        $pdf = new TCPDF_wrapper();
        $pdf->SetTitle('Hello World');
        $pdf->AddPage();
        $pdf->SetFont('helvetica', '', 12);
        $pdf->Cell(0, 10, 'Hello World', 0, 1, 'C');
        $pdf->Output();
    }
}
?>

Step 5: Accessing the Generate PDF Method

1. Configure a route to access the generate_pdf() method.
2. Open the application/config/routes.php file.
3. Add the following line to the file:

$route['generate-pdf'] = 'PdfController/generate_pdf';

Now you can access the generate_pdf() method by accessing the URL http://your_domain/generate-pdf, and it will generate a PDF with the text "Hello World". You can modify the content and styling of the PDF according to your requirements.
