How to do it? New Description Field in Image Edit Section
Taking a look at UploadField (the image upload form) it looks like this form is 'EditForm'. The fields from this form are populated from UploadField::getFileEditFields() which calls getCMSFields() on the File object.
So using that understanding, modifying the getCMSFields function on the File object is easy.
1) Create an extension
**mysite/code/FileExtension.php**
<?php
class FileExtension extends DataExtension {
private static $db = array(
'ExtraField' => 'Varchar'
);
public function updateCMSFields(FieldList $fields) {
$fields->addFieldToTab('Root.Main', new TextField('ExtraField'));
}
2) Apply your extension to File
In _config.php
Object::add_extension('File', 'FileExtension');
(OR use YAML)
File:
extensions:
- FileExtension
3) Rebuild your database and visit your page with '?flush=1' to clear the cache
