如何调整文件中的图像获取内容

Question

I'm using codeigniter and i want to resize image from user that upload via url.

Here is my code:

            //upload via url
            $url = $this->input->post('photo');
            /* Extract the filename */
            $filename = substr($url, strrpos($url, '/') + 1);
            /* Save file wherever you want */
            file_put_contents('myuploads/'.$filename, file_get_contents($url));
            //resize start
            $config['image_library'] = 'gd2';
            $config['source_image']  = $filename;
            $config['overwrite']     = TRUE;
            $config['width'] = 59;
            $config['height'] = 90;
            $this->load->library('image_lib', $config);
            $this->image_lib->initialize($config);
            $this->image_lib->resize();
            $data=array(
                'username'=>$this->input->post('username'),
                'deskrip'=>$this->input->post('deskrip'),
                'photo'=>$filename
              );
            $this->db->where('id',$id);
            $outp = $this->db->update('user',$data);

Upload is working but the problem is the image won't resize into 59x90 and still in original size.

Any answer?

Many thanks..

Answer 1

resize() method is working or not you can see error by :

    if ( ! $this->image_lib->resize())
{
    echo $this->image_lib->display_errors();
}

see Documentation There is a nice tutorial of image Manipulation ,from tutsplus

Hope this help you.

Thanks
