SS3 UploadField

7 July 2012 at 5:14pm Last edited: 7 July 2012 5:39pm
Hi,
I have 2 questions regarding using Uploadfield in frontend to upload images:
1) By default, uploadfield will upload images as 'File'. I have a custom class called "ProfilePhoto" that extends "Image" which extends "File". Is there a way to configure uploadfield so that it upload images as "ProfilePhoto" ?
2) The "ProfilePhoto" has a Has-One relationship to "Member". How do I configure the UploadField so that after the image is uploaded, it will auto-detect and update the relationship.

Hi there,
even if it is not that old, let me wake up this thread.
I have the same problem with the UploadField.
I want to use it in a frontendform instead of the SimpleImageField, that I have used in the previous Silverstripe Versions.
First, is there any way, to configure the UploadField, to hide the "From Files" Button.
Next: If I make the UploadField Required, it returns the UploadField always with the error message, that it was not filled.
Also, it seems, that I can't write it's content to the DataObject by $form->saveInto(DATAOBJECT).
Here is a Piece of code that I use:
// CRUD
public function MitarbeiterAddForm(){$data = Session::get("FormInfo.Form_MitarbeiterAddForm.data");
$avatarField = new UploadField('Avatar', 'Mitarbeiter Photo');
$avatarField->allowedExtensions = array('jpg', 'gif', 'png');
$avatarField->setFolderName('mitarbeiter01');
//print_r($avatarField->getAttributes()); die();// Create fields
$fields = new FieldList(
new TextField('Name', 'Name'),
$avatarField
);// Create actions
$actions = new FieldList(
new FormAction('doAdd', 'Mitarbeiter anlegen')
);$requiredFields = new RequiredFields(
'Name'
//'Avatar'
);$form = new Form($this, 'MitarbeiterAddForm', $fields, $actions, $requiredFields);
if(is_array($data)){
$form->loadDataFrom($data);
}
return $form;
}public function doAdd($data, $form){
$errors = false;
if($Mitarbeiter = DataObject::get_one('Mitarbeiter01', "Name='".Convert::raw2sql($data['Name'])."'")){
$form->addErrorMessage('Name', 'Ein Mitarbeiter mit diesem namen existiert bereits.', 'bad');
$errors = true;
}if($errors){
Session::set("FormInfo.Form_MitarbeiterAddForm.data", $data);
return $this->redirectBack();
}$o_Mitarbeiter = new Mitarbeiter01();
$form->saveInto($o_Mitarbeiter);
$o_Mitarbeiter->write();Session::clear("FormInfo.Form_MitarbeiterAddForm.data");
// return Director::redirect($this->URLSegment.'/profile');
// We use Email Verified Member
return $this->redirect('mitarbeiter01/all');
}/**
* Show the registration form
*/
public function all(){$tmpPage = new Page();
$tmpPage->Title = 'Mitarbeiter';
$tmpPage->URLSegment = self::$url_segment;
$tmpPage->ID = -1; // Set the page ID to -1 so we dont get the top level pages as its children
$controller = new BaseController01($tmpPage);
$controller->init();// WebApps
if(!isset($_GET['start']) || !is_numeric($_GET['start']) || (int)$_GET['start'] < 1) $_GET['start'] = 0;
//$CurrentWebApps = Member::currentUser()->WebApps()->getRange((int)$_GET['start'], 10);$customisedController = $controller->customise(array(
'Title' => 'Mitarbeiter',
'Content' => "<p>Mitarbeiter Liste</p>",
"Form" => $this->MitarbeiterAddForm(),
"Mitarbeiter" => DataObject::get('Mitarbeiter01', '', '', '', (int)$_GET['start'].", 10")
));
return $customisedController->renderWith(array('MitarbeiterController01_all', 'MitarbeiterController01', 'Page', $this->owner->stat('template_main'), 'ContentController'));

Hi... I have managed to figure out how to use the UploadField at FrontEnd and It will automatically manage the relationship.
.
Note my database design is as below:
MemberProfile object has a has-one relationship to ProfilePhoto object
ProfilePhoto object extends the Image object.
MemberProfile object also has a has-one relationship to Member object.My code is as below:
public function getFrontendFields_edit_profilePhoto() {
$CurrentMember = Member::currentUser();
$CurrentMemberID = Member::currentUserID();$CurrentMemberProfile = DataList::create('MemberProfile')->filter('MemberID', $CurrentMemberID)->First();
$CurrentProfilePhotos = DataList::create("ProfilePhoto")->filter(array('MemberProfileID' => $CurrentMemberID);$fields = new FieldList();
$fields->push($imageField = new UploadField('ProfilePhoto', 'Upload Profile Photo', $CurrentProfilePhotos)));
$imageField->getValidator()->setAllowedExtensions(array('jpg', 'jpeg', 'png', 'gif'));
$imageField->setConfig('allowedMaxFileNumber', 1);
$path = preg_replace('/^' . ASSETS_DIR . '\//', '', 'Uploads/' . $CurrentMemberID);
$imageField->setFolderName($path);
$imageField->setConfig('previewMaxWidth', 40);
$imageField->setConfig('previewMaxHeight', 40);
$imageField->setRecord($CurrentMemberProfile);
return $fields;
}Note that it is important to set the canCreate / canView / canEdit / canDelete functions in the ProfilePhoto class.
Hope it helps those facing the same problems.

I have also managed to hide the "From Files" button by using my own UploadField, I am not sure whether it is best practice but it works well.
Steps as below:
1) Create mysite/code/forms/UploadField_FrontEnd.php
<?php
/**
*
* Extends the Upload and modift the template so that it won't display the option "From Files"
*/
class UploadField_FrontEnd extends UploadField {}
2) Create mysite/code/templates/UploadField_FrontEnd.ss
Copy the code from framework/templates/UploadField.ss and delete the "From Files" html code.
3) Replace UploadField with UploadField_FrontEnd in your form code, for eg:
$fields->push($imageField = new UploadField_FrontEnd('ProfilePhoto', 'Upload Profile Photo', $CurrentProfilePhotos)));
4) Run ?dev/build and ?flush=1
