CI_Upload::data()

data([$index = NULL])

Parameters:	$data (string) – Element to return instead of the full array
Returns:	Information about the uploaded file
Return type:	mixed

This is a helper method that returns an array containing all of the data related to the file you uploaded. Here is the array prototype:

Array
(
        [file_name]     => mypic.jpg
        [file_type]     => image/jpeg
        [file_path]     => /path/to/your/upload/
        [full_path]     => /path/to/your/upload/jpg.jpg
        [raw_name]      => mypic
        [orig_name]     => mypic.jpg
        [client_name]   => mypic.jpg
        [file_ext]      => .jpg
        [file_size]     => 22.2
        [is_image]      => 1
        [image_width]   => 800
        [image_height]  => 600
        [image_type]    => jpeg
        [image_size_str] => width="800" height="200"
)

To return one element from the array:

$this->upload->data('file_name');       // Returns: mypic.jpg

Here’s a table explaining the above-displayed array items:

Item	Description
file_name	Name of the file that was uploaded, including the filename extension
file_type	File MIME type identifier
file_path	Absolute server path to the file
full_path	Absolute server path, including the file name
raw_name	File name, without the extension
orig_name	Original file name. This is only useful if you use the encrypted name option.
client_name	File name as supplied by the client user agent, prior to any file name preparation or incrementing
file_ext	Filename extension, period included
file_size	File size in kilobytes
is_image	Whether the file is an image or not. 1 = image. 0 = not.
image_width	Image width
image_height	Image height
image_type	Image type (usually the file name extension without the period)
image_size_str	A string containing the width and height (useful to put into an image tag)
