Codeigniter图像调整大小库无法正常工作

Question

for($i=0; $i< count($data['upload_data']); $i++){

                //resize uploade image
                $config['image_library'] = 'gd2';
                $config['source_image'] = $data['upload_data'][$i]['full_path'];
                $config['new_image'] = $data['upload_data'][$i]['full_path'];
                $config['maintain_ratio'] = TRUE;
                $config['width']    = 700;
                $config['height']   = 700;

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

                $this->image_lib->resize(); 
                $this->image_lib->clear();
}

I want to resize the images in a loop, all the images are already in the database, but after running this script, only the first image is resized.

All the path are correct, anyone else encountering this problem?

After loading image_lib you might need to initialize it.

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

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

See: https://ellislab.com/codeigniter/user-guide/libraries/image_lib.html

You will NOT need to use the $this->image_lib->initialize function if you save your preferences in a config file.
