Silverstripe:从 many_many 关系自定义上传中获取 var [英] Silverstripe: get var from many_many relation custom upload

问题描述

我想知道如何自定义此上传字段以从 $belongs_many_many Act 表中获取.

I would like to know how customize this uploadfield to get from $belongs_many_many Act table.

部分代码....

<? 

class MultipleBlock extends DataObject {

    private static $db = array(
        'Act' => 'Varchar',


    private static $many_many = array(
        'MultipleBlockColumns' => 'MultipleBlockColumn'
    );


}

class MultipleBlockColumn extends DataObject {

    static $belongs_many_many = array(
        'MultipleBlocks' => 'MultipleBlock'
    );
    private static $has_one = array(
        'Image' => 'Image',
    );

    $fields->addFieldToTab('Root.Image',$uploadField = new UploadField(
                $name = 'Image',
                $title = 'Image'
            )    
        );

    enter code here
    $uploadField->setFolderName('Uploads/Subsite'.Subsite::currentSubsiteID().'/images/'.$var);

}

我尝试了这些方法来获取 Act 变量，但没有出现:

I have tried these methods to get Act variable but nothing appear:

$var=$this->Parent->MultipleBlocks->Act;
$var=$this->many_many(MultipleBlocks)->Act;
$var=$this->Parent->Act;

有什么想法吗?提前致谢！

Any idea? Thanks in advance!

推荐答案

哇...经过几天的学习，对 Silverstripe 有了更多的了解，我找到了我的解决方案.从 MultiBlock 列实现 MultiBlocks 是这样的:

Wow... after some days, and learning Silverstripe little more, I have found my solution. To achieve MultiBlocks from MultiBlock column is this :

parent::MultipleBlocks();

为了自定义保存到文件夹，有我的代码...它运行良好.必须先创建 MultiBlockColumns 的 ID.

To make my save to folder customization, there is my code... It works perfectly well. The ID of the MultiBlockColumns must be create first.

$parent = parent::MultipleBlocks();
            $uploadField->setFolderName('Uploads/Subsite'.Subsite::currentSubsiteID().'/images/'.$parent['MultipleBlock']->Act);

就是这样！感谢您提交想法.

That's it! Thanks for submitting idea.
