Class SimpleImageField
SimpleImageField provides an easy way of uploading images to Image
has_one relationships. These relationships are auto-detected if you name the
field accordingly. Unlike 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:
class Article extends DataObject { static $has_one = array('MyImage' => 'Image'); } // use in your form constructor etc. $myField = new SimpleImageField('MyImage');

Field( )
Returns the form field - used by templates. Although FieldHolder is generally what is inserted into templates, all of the field holder templates make use of $Field. It's expected that FieldHolder will give you the "complete" representation of the field on the form, whereas Field will give you the core editing widget, such as an input tag. |
