To download existing files in CodeIgniter, you can use the following method:
- Create a controller in your CodeIgniter application to handle the download process. You can create a new controller or use an existing one. For this example, let's create a new controller called Download.
- In the Download controller, create a method to handle the file download process. You can use the following code as a starting point:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
public function index()
{
$filename = 'path_to_your_file.pdf'; // Change this to the path of the PDF, Excel, or text file you want to download
// Check if the file exists
if (file_exists($filename)) {
// Set the appropriate headers
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="' . basename($filename) . '"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($filename));
// Flush the output buffer
ob_clean();
flush();
// Read the file and output its contents
readfile($filename);
} else {
echo 'File not found';
}
}
|
- Replace 'path_to_your_file.pdf' with the actual path to the file you want to download. You can also change the Content-Type header based on the type of file you are downloading (e.g., application/pdf for PDF files, application/vnd.ms-excel for Excel files, text/plain for text files).
- Use the following URL to trigger the file download process in your browser:

http://localhost/your_project_name/index.php/download |
That's it! You should now be able to download existing PDF, Excel, or text files in CodeIgniter using the above method.
