To create a PDF in CodeIgniter, you can use libraries such as TCPDF or FPDF. These libraries allow you to generate PDF files by simply writing PHP code. First, you need to download the library and add it to your CodeIgniter project. Then, you can create a controller in CodeIgniter that will handle the PDF generation logic. This controller can load the library and call its functions to add content to the PDF file. You can customize the PDF layout and styling by modifying the code in the controller. Once the PDF file is ready, you can then prompt the user to download or view the file in the browser. With the help of these libraries, creating PDF files in CodeIgniter is a straightforward process that can be done efficiently with PHP code.
What is the recommended way to handle PDF generation in CodeIgniter?
There are several libraries and plugins available for generating PDF files in CodeIgniter. One popular and recommended way is by using the "mpdf" library.
To use mpdf in your CodeIgniter project, you can follow these steps:
- Download the mpdf library from the official website (https://mpdf.github.io/).
- Extract the downloaded files and place them in your CodeIgniter project directory (e.g. application/third_party/mpdf).
- Create a new helper file (e.g. Mpdf_helper.php) in the application/helpers directory and add the following code:
1 2 3 4 5 6 7 8 9 10 11 12 |
<?php if (!defined('BASEPATH')) exit('No direct script access allowed'); require_once APPPATH.'/third_party/mpdf/vendor/autoload.php'; class Mpdf_helper { public function generate_pdf($html, $filename) { $mpdf = new \Mpdf\Mpdf(); $mpdf->WriteHTML($html); $mpdf->Output($filename, 'I'); } } |
- Load the helper file in your controller where you want to generate the PDF file:
1
|
$this->load->helper('mpdf');
|
- Generate the PDF file by calling the generate_pdf function in your controller method:
1 2 3 |
$html = '<h1>Hello, World!</h1>'; $filename = 'example.pdf'; generate_pdf($html, $filename); |
- Access the controller method through the browser to generate and download the PDF file.
By following these steps, you can easily generate PDF files in CodeIgniter using the mpdf library.
What is the difference between TCPDF and FPDF in CodeIgniter?
TCPDF and FPDF are both libraries for generating PDF files in PHP. The main differences between the two are:
- TCPDF is a newer library and is more actively maintained than FPDF. It offers more features and supports newer PHP versions.
- TCPDF has better support for Unicode characters, allowing you to use different languages and special characters in your PDF files.
- TCPDF has better support for CSS styles, allowing you to style your PDF files more easily and accurately.
- FPDF is simpler and easier to use for basic PDF generation tasks, while TCPDF is more advanced and may have a steeper learning curve.
Overall, TCPDF is generally recommended for most PDF generation tasks in CodeIgniter due to its more modern features and better support.
What is the default page size for a PDF generated using CodeIgniter?
The default page size for a PDF generated using CodeIgniter is A4 (210mm x 297mm).
How to create a PDF form in CodeIgniter?
To create a PDF form in CodeIgniter, you can use the TCPDF library which is a free and open-source PHP class for generating PDF documents. Here are the steps to create a PDF form in CodeIgniter using TCPDF:
- Download TCPDF library: Download the TCPDF library from the official website (https://tcpdf.org/) and extract the files to your CodeIgniter project directory.
- Create a controller: Create a new controller in your CodeIgniter project to handle the PDF form generation. You can name the controller as "PdfController" or any other name of your choice.
- Load TCPDF library: In the constructor of your controller, load the TCPDF library by including the main TCPDF class file.

|
require_once APPPATH.'/third_party/tcpdf/tcpdf.php';
|
- Create a method to generate the PDF form: Create a method in your controller to generate the PDF form using TCPDF. You can define the layout of the form fields, labels, and buttons as per your requirements.
1 2 3 4 5 6 7 8 9 10 11 12 |
public function generate_pdf_form() { $pdf = new TCPDF(); $pdf->AddPage(); $pdf->SetFillColor(255, 255, 255); $pdf->SetXY(10, 10); $pdf->Cell(0, 10, 'My PDF Form', 0, 1, 'L', 1); // Add form fields, labels, and buttons here // Output the PDF to the browser $pdf->Output('my_pdf_form.pdf', 'I'); } |
- Access the PDF form: To access the PDF form, you can create a route in the routes.php file of your CodeIgniter project to map a URL to the generate_pdf_form method of your controller.
1
|
$route['generate-pdf-form'] = 'PdfController/generate_pdf_form';
|
Now, you can access the PDF form by visiting the URL mapped to the generate_pdf_form method of your controller. The PDF form generated using TCPDF will be displayed in the browser for the user to fill out and submit.
