INSTALLATION GUIDE:

1. Download the repository;

2. Copy thumb_helper.php to your ./application/helpers/ folder;

That's it, your good to go.

---

USAGE:

1. Loading the Helper

$this->load->helper('thumb');

USING WITH UPLOAD LIBRARY:

After uploading a image you have access to an simple array that has all the information about your image.

Like this:

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

Info on $image_data:

More information about this here: Codeigniter/user_guide/libraries/file_uploading

For now you can pass 4 params to the thumb helper:

1. Image data from upload;

2. Width

3. Height

4. Destination path

like this:

create_thumb($image_data, '100', '150', '.public/images/thumbs/');

Keep in mind that the 3rd param is optional. If only two params are passed to the thumb helper the thumb will resize the image maintaining the ratio. If theres a 3rd param the ratio will be equal to FALSE.

After the creation the thumb helper will return an array with the following content:

path -> The full path to the image;

thumb_marker -> The marker for the thumb, for now will always be equal to the thumb sizes that were passed to the thumb helper;

thumb_name -> The final name of the thumb;

I made this return in case someone needed to sent some of these values to the database for example.

USING REMOTE FILE:

For that insted of passing the array from image upload you can just pass the path to the file (including the file).

example:

create_thumb('./public/images/myimage.jpg', '100', '150');
