在codeigniter php中设置图像的宽度和高度不起作用

Question

i have a codeigniter website where user can upload multiple images, i want all the images to be of the same size, i have done the following code in controller:

if (isset($_POST['addblog'])) {
    $this->load->library('upload');
    $image = array();
    $ImageCount = count($_FILES['image_name']['name']);

    for ($i = 0; $i < $ImageCount; $i++) {
        $_FILES['file']['name'] = $_FILES['image_name']['name'][$i];
        $_FILES['file']['type'] = $_FILES['image_name']['type'][$i];
        $_FILES['file']['tmp_name'] = $_FILES['image_name']['tmp_name'][$i];
        $_FILES['file']['error'] = $_FILES['image_name']['error'][$i];
        $_FILES['file']['size'] = $_FILES['image_name']['size'][$i];

        $uploadPath = './uploads/blog/';
        $config['upload_path'] = $uploadPath;
        $config['allowed_types'] = 'jpg|jpeg|png|gif';
        $config['width'] = 200;
        $config['height'] = 250;

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

        if ($this->upload->do_upload('file')) {

            $imageData = $this->upload->data();

            $uploadImgData[] = $imageData['file_name'];
        }
    }
    $blogimage = $uploadImgData;
}

as u can see i have set the height and width in config, the images are still uploaded in ther original size, can anyone please tell me what is wrong in here, thanks in advance

You has just made a little mistake in your config :

$config['max_width'] = 200; 
$config['max_height'] = 250; 

Sadly "min_width" and "min_height" seems doesn't exist yet
