To use a custom function for uploading files in CodeIgniter, you can follow these steps:

  1. Create a new function in your controller that will handle the file upload process. This function should load the necessary libraries and helpers for file uploading.
  2. Define the function parameters to accept the file input field name from the form.
  3. Inside the function, use the CodeIgniter file upload library to process the file upload. You can set the configuration options for file upload such as file type, file size, upload directory, etc.
  4. After the file upload is successful, you can return the uploaded file information or display a success message to the user.


Here is an example of a custom file upload function in a CodeIgniter controller:

public function upload_file() {
    // Load the file upload library
    $this->load->library('upload');

    // Set file upload configuration
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|jpeg|png';
    $config['max_size'] = 1000; // in KB

    // Initialize file upload
    $this->upload->initialize($config);

    // Check if file upload is successful
    if ($this->upload->do_upload('file_input_name')) {
        // File uploaded successfully, get the uploaded file data
        $upload_data = $this->upload->data();
        $file_name = $upload_data['file_name'];

        // You can do further processing with the uploaded file here

        // Display success message to the user
        echo 'File uploaded successfully: ' . $file_name;
    } else {
        // File upload failed, display error message
        echo 'Error uploading file: ' . $this->upload->display_errors();
    }
}


Ensure that you also have a form in your view with the appropriate file input field and submit button that will trigger the file upload function in your controller.
