Watermark image upload in codeigniter

Question

Hello! I’m trying to insert watermark when registering the image, but the image is upada, only it does not insert the watermark and does not return errors, someone has some suggestion?

Follows code below:

foreach ($_FILES as $field => $file) {
        if ($file['error'] == 0) {
            if ($this->upload->do_upload($field)) {
                $data = $this->upload->data();
                $dados['imagem'] = $data['file_name'];       

                $img_config['wm_type'] = 'overlay';
                $img_config['wm_overlay_path'] = PATH_FRONT_END_UPLOAD.'usuarios/logo.png';
                $img_config['wm_x_transp'] = 20;
                $img_config['wm_y_transp'] = 10;
                $img_config['wm_opacity'] = 50;
                $img_config['wm_vrt_alignment'] = 'bottom';
                $img_config['wm_hor_alignment'] = 'center';
                $config['source_image'] = $data['full_path'];  
                $this->image_lib->watermark();
                $this->image_lib->clear();
                $this->image_lib->initialize($config); 
            } else {
                $errors = $this->upload->display_errors();
                die($errors);
            }
        }
    }

Good afternoon. I had a similar problem with generation of thumbnails. The solution was to load the lib out of the foreach and with each new configuration parameterized, I used the following code:

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

I hope I’ve helped!

Updated: Try the following code:

foreach ($_FILES as $field => $file) {
        if ($file['error'] == 0) {
            if ($this->upload->do_upload($field)) {
                $data = $this->upload->data();
                $dados['imagem'] = $data['file_name'];       

                $img_config['wm_type'] = 'overlay';
                $img_config['wm_overlay_path'] = PATH_FRONT_END_UPLOAD.'usuarios/logo.png';
                $img_config['wm_x_transp'] = 20;
                $img_config['wm_y_transp'] = 10;
                $img_config['wm_opacity'] = 50;
                $img_config['wm_vrt_alignment'] = 'bottom';
                $img_config['wm_hor_alignment'] = 'center';
                $config['source_image'] = $data['full_path'];  
                $this->image_lib->clear();
                $this->image_lib->initialize($img_config);                 
                $this->image_lib->watermark();

            } else {
                $errors = $this->upload->display_errors();
                die($errors);
            }
        }
    }
