Question

我无法通过Silverstripe中的前端表单上传图片。我看过这个page上的例子，但它对我没有帮助。更新文本字段工作正常。我的代码发布在下面，我错过了什么？

public function ChecklistForm()
{
    $checklist = Checklist::get()->byID($this->request->param('ID'));

    $form = Form::create(
        $this,
        __FUNCTION__,
        FieldList::create(
            TextField::create('Object','')
                ->addExtraClass('form-control')
                ->setAttribute('placeholder','Object')
                ->setAttribute('value', $checklist->Object),
            TextField::create('Contact','')
                ->addExtraClass('form-control')
                ->setAttribute('placeholder','Contact')
                ->setAttribute('value', $checklist->Contact),
            TextField::create('Address','')
                ->addExtraClass('form-control')
                ->setAttribute('placeholder','Address')
                ->setAttribute('value', $checklist->Address),
            HiddenField::create('ChecklistId','')
                ->setAttribute('value', $this->request->param('ID')),
            UploadField::create('Images','Upload Images')
                ->setFolderName('checklist-images')

        ),
        FieldList::create(
            FormAction::create('handleChecklist','Update Checklist')
                ->setUseButtonTag(true)
                ->addExtraClass('btn btn-default-color btn-lg')
        ),
        RequiredFields::create('Object','Contact','Address')
    )
    ->addExtraClass('form-style');

    return $form;
}

public function handleChecklist($data, $form)
{
    $checklist = Checklist::get()->byID($data['ChecklistId']);

    $checklist->Object = $data['Object'];
    $checklist->Contact = $data['Contact'];
    $checklist->Address = $data['Address'];
    $form->saveInto($checklist);
    $checklist->write();

    $form->sessionMessage('Checklist has been updated!','good');

    return $this->redirectBack();
}

您之后错过了逗号：

HiddenField::create('ChecklistId','')
            ->setAttribute('value', $this->request->param('ID'))

使用UploadField以前端形式上传图片Silverstripe 4.0
