/**
|
|
* A field that allows you to attach an image to a record from within a iframe - designed for use in AJAX forms where it
|
|
* is not possible to use {@link SimpleImageField}.
|
|
*
|
|
* <b>Usage</b>
|
|
*
|
|
* If you want to upload all assets from this field to a given folder you can define the folder in 2 ways. Either in the constructor or as a method on the field
|
|
*
|
|
* <code>
|
|
* $myField = new ImageField("myName", "Upload image below", null, null, null, "myFolder");
|
|
* </code>
|
|
*
|
|
* Will upload images into the assets/myFolder folder. If that folder does not exist it will create it for you. You can also define it as a method
|
|
*
|
|
* <code>
|
|
* $myField = new ImageField("myName");
|
|
* $myField->setFolderName('myFolder');
|
|
* </code>
|
|
*
|
|
* @deprecated 3.0 Use UploadField with $myField->allowedExtensions = array('jpg', 'gif', 'png')
|
|
*
|
|
* @package forms
|
|
* @subpackage fields-files
