Multiple thumbnails just isn't happening. - El Forum - 08-13-2009

For some reason I cannot convert more than one thumbnail.

Code:
if ($this->upload->do_upload('picture1'))

            {

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

                $db['picture1'] = $data['file_name'];

                $lib['image_library'] = 'gd2';

                $lib['create_thumb'] = TRUE;

                $lib['maintain_ratio'] = TRUE;

                $lib['width'] = 200;

                $lib['height'] = 200;

                $lib['new_image'] = getcwd() . '/web/uploads/profile_thumbs/'.$data['file_name'];

                $lib['source_image'] = $source.$data['file_name'];

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

                $this->image_lib->resize();

            }

            if ($this->upload->do_upload('picture2'))

            {

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

                $db['picture2'] = $data['file_name'];

                $lib['image_library'] = 'gd2';

                $lib['create_thumb'] = TRUE;

                $lib['maintain_ratio'] = TRUE;

                $lib['width'] = 100;

                $lib['height'] = 100;

                $lib['new_image'] = getcwd() . '/web/uploads/profile_thumbs/'.$data['file_name'];

                $lib['source_image'] = $source.$data['file_name'];

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

                echo $this->image_lib->display_errors();

            }

The second picture2 doesn't resize the image and doesn't display any errors. A picture is being uploaded. Any ideas what is happening here?

Hi,
change upload field names as array and use foreach loop to generate thumbnails.

Can you clarify this please. The filenames are in the db array. How would I use a foreach to loop through these thumbnails? I do not see how this would be much different to what I am doing now. If the 'if' statements are not working then why would a foreach loop?

You load the image library twice and you omitted calling resize() for the second image; try this instead:
User guide:

Quote:The clear function resets all of the values used when processing an image. You will want to call this if you are processing images in a loop.

Code:
$this->image_lib->clear();

Code:
if ($this->upload->do_upload('picture1'))

            {

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

                $db['picture1'] = $data['file_name'];

                $lib['image_library'] = 'gd2';

                $lib['create_thumb'] = TRUE;

                $lib['maintain_ratio'] = TRUE;

                $lib['width'] = 200;

                $lib['height'] = 200;

                $lib['new_image'] = getcwd() . '/web/uploads/profile_thumbs/'.$data['file_name'];

                $lib['source_image'] = $source.$data['file_name'];

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

                $this->image_lib->resize();

                $this->image_lib->clear();

            }

            if ($this->upload->do_upload('picture2'))

            {

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

                $db['picture2'] = $data['file_name'];

                $lib['image_library'] = 'gd2';

                $lib['create_thumb'] = TRUE;

                $lib['maintain_ratio'] = TRUE;

                $lib['width'] = 100;

                $lib['height'] = 100;

                $lib['new_image'] = getcwd() . '/web/uploads/profile_thumbs/'.$data['file_name'];

                $lib['source_image'] = $source.$data['file_name'];

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

                $this->image_lib->resize();

                echo $this->image_lib->display_errors();

            }
