I am a bit stuck with image manipulation and thumbnail generation. I have a controller that process a file uploaded and is supposed to do the following:-
1. SAVE THE IMAGE TO A DIRECTORY AFTER RENAMING IT ($string)
2. RESIZE THE IMAGE
3. CREATE A THUMBNAIL OF THE RESIZED IMAGE SO THAT TWO IMAGES SHOULD EXIST IN THE DIRECTORY.
The script below works as far as creating the directory and the new re-sized image, but I can't seem to then create a thumbnail of the resized image. Any ideas?
Code:
//upload photo file
public function upload_file() {
$this->load->model('image_file');
$string = $this->image_file->string_generate();
$set_image_path = $this->image_file->set_image_path($string);
$config['upload_path'] = $set_image_path;
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['max_size'] = '4000';
$config['max_width'] = '6000';
$config['max_height'] = '4000';
$config['file_name'] = $string;
$this->load->library('upload', $config);
//write the data to the photo db
$mem_id = $this->session->userdata('mem_id');
$this->image_file->write_imagedata($mem_id, $string, $set_image_path);
//create the directory
mkdir($set_image_path, 0644, true);
//do upload & process image (rezize and rename)
$this->upload->do_upload('userphoto');
$results = $this->upload->data();
$config['image_library'] = 'gd2';
$config['source_image'] = $set_image_path.$string;
$config['create_thumb'] = FALSE;
$config['maintain_ratio'] = TRUE;
$config['quality'] = 50;
$config['width'] = 800;
$config['height'] = 600;
$this->load->library('image_lib', $config);
$this->image_lib->resize();
$this->image_lib->clear();
//create thumbnail
$config['image_library'] = 'gd2';
$config['source_image'] = $set_image_path.$string;
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['quality'] = 50;
$config['width'] = 200;
$config['height'] = 150;
$this->image_lib->resize();
It seems to get as far as the //create thumbnail but doesn't process anything beyond this.
