Why Am I Getting \'You Did Not Select a File to Upload\' When Uploading Multiple Files in CodeIgniter?

Multiple File Uploads with CodeIgniter

Issue:

When attempting to upload multiple files using the provided example, the error message "You did not select a file to upload." persistently appears.

Solution:

The issue lies within the upload method. To correctly upload multiple files using CodeIgniter, the code should be updated as suggested below:

private function upload_files($title, $files)
{
    $config = array(
        'upload_path'   => './upload/real_estate/',
        'allowed_types' => 'jpg|gif|png',
        'overwrite'     => 1,                       
    );

    $this->load->library('upload', $config);

    foreach ($files['name'] as $key => $image) {
        $_FILES['images[]']['name']= $files['name'][$key];
        $_FILES['images[]']['type']= $files['type'][$key];
        $_FILES['images[]']['tmp_name']= $files['tmp_name'][$key];
        $_FILES['images[]']['error']= $files['error'][$key];
        $_FILES['images[]']['size']= $files['size'][$key];

        $config['file_name'] = $title .'_'. $image;

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

        if ($this->upload->do_upload('images[]')) {
            $this->upload->data();
        } else {
            return false;
        }
    }

    return true;
}

Explanation:

The primary difference lies in the initialization of the upload method. When using multiple file inputs with the same name, the input array must be referenced as '$_FILES['images[]']', instead of '$_FILES['images']', as seen in the corrected code provided. This ensures that each individual file is processed and uploaded correctly.
