/**
|
|
* SimpleImageField provides an easy way of uploading images to {@link Image} has_one relationships.
|
|
* These relationships are auto-detected if you name the field accordingly.
|
|
* Unlike {@link ImageField}, it doesn't use an iframe.
|
|
*
|
|
* Restricts the upload size to 2MB by default, and only allows upload
|
|
* of files with the extension 'jpg', 'gif' or 'png'.
|
|
*
|
|
* Example Usage:
|
|
* <code>
|
|
* class Article extends DataObject {
|
|
* static $has_one = array('MyImage' => 'Image');
|
|
* }
|
|
* // use in your form constructor etc.
|
|
* $myField = new SimpleImageField('MyImage');
|
|
* </code>
|
|
*
|
|
* @package forms
|
|
* @subpackage fields-files
