To upload a zip file in CodeIgniter, you can use the following steps:

  1. First, ensure that the upload library is loaded in your controller. You can do this by adding the following line of code in your controller's constructor or in the function where you want to use the upload library:
1
$this->load->library('upload');


  1. Then, set the configuration options for the upload. You can do this by setting the values in an array and passing the array to the initialize method of the upload library. Here is an example of the configuration options:
 1

10
$config = array(
    'upload_path' => './uploads/',  // the path where the uploaded zip file will be stored
    'allowed_types' => 'zip',       // allowed file types
    'max_size' => 1024,             // maximum file size in kilobytes
    'max_width' => 0,               // maximum width of the image in pixels
    'max_height' => 0,              // maximum height of the image in pixels
    'file_name' => 'myzipfile.zip'  // the name of the file to be uploaded
);

$this->upload->initialize($config);


  1. Next, use the do_upload method of the upload library to handle the actual file upload. This method returns a boolean value indicating whether the upload was successful or not.

5
if ($this->upload->do_upload('zip_file')) {
    // file upload was successful
} else {
    // file upload failed
}


  1. If the file upload was successful, you can access the uploaded file data using the data method of the upload library. This method returns an array containing information about the uploaded file, such as the file name, file size, and file type.
1
$upload_data = $this->upload->data();


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

To upload a zip file in Codeigniter, you can follow these steps:

  1. Create a form in your view file (upload_view.php) to allow users to select and upload the zip file.

  1. Create a method in your controller (UploadController.php) to handle the upload process.

class UploadController extends CI_Controller {
    
    public function process() {
        $config['upload_path'] = './uploads/';
        $config['allowed_types'] = 'zip';
        $this->load->library('upload', $config);

        if (!$this->upload->do_upload('zip_file')) {
            // Handle upload error
            $error = $this->upload->display_errors();
            echo $error;
        } else {
            // Upload success
            $data = $this->upload->data();
            $zip_path = $data['full_path'];

            // Extract the ZIP file
            $extract_dir = './uploads/extracted/';
            $this->zip->extract($zip_path, $extract_dir);

            // Process the extracted files
            // ...
        }
    }
}


  1. Make sure to load the necessary helper and library in your controller's constructor.

class UploadController extends CI_Controller {
    
    public function __construct() {
        parent::__construct();
        $this->load->helper('url');
        $this->load->library('zip');
    }
    
    // ...
}


  1. Finally, make sure you have set the appropriate permissions on the ./uploads/ and ./uploads/extracted/ directories, so that Codeigniter can read, write, and extract files.


That's it! Now users can select a zip file using the form and upload it. The zip file will be stored in the ./uploads/ directory. You can then use the zip library in Codeigniter to extract the uploaded zip file and process the extracted files as per your requirements.
