Question

我试图找出一种方法（如果可能的话）删除或隐藏自定义标签中的某些字段。自定义选项卡标有＆＃34; Rotator＆＃34;它包含可用于页面上旋转横幅的图像。主页横幅略有不同，因为它在子页面上还有2个额外的字段：BackgroundImage和Body（用于存放各种文本）。我想让内容管理器变得简单，所以我想在子页面上隐藏这些字段。

我知道removeFieldFromTab及其工作原理，我正在考虑在Page.php文件中使用它（因为它基本上是我的SilverStripe文件中所有页面类型的主模板）：

  public function getCMSFields() {
    $fields = parent::getCMSFields();

    $gridFieldConfig = GridFieldConfig_RecordEditor::create();

    $gridFieldConfig->addComponent(new GridFieldBulkImageUpload());
    $gridFieldConfig->addComponent(new GridFieldSortableRows('SortOrder'));

    $gridFieldConfig->getComponentByType('GridFieldDataColumns')->setDisplayFields(array(
        // field from drawer class => label in UI
        'ID' => 'ID',
        'Title' => 'Title',
        'Thumbnail' => 'Thumbnail',
        'InternalURL.Link' => 'Internal URL',
    ));

    $gridfield = new GridField(
        "Rotator",
        "Rotator",
        $this->Rotator()->sort("SortOrder"),
        $gridFieldConfig
    );

    $fields->addFieldToTab('Root.Rotator', $gridfield);
    $fields->addFieldToTab("Root.Main", new TextField("H1"), "Content");
    $fields->addFieldToTab("Root.Main", new TextField("Subheader"), "Content");
    $fields->addFieldToTab('Root.Main', new TextField('PageTitle', 'Page Title'), 'MetaDescription');
    $fields->removeFieldFromTab('Root.Rotator', 'Body');
    $fields->removeFieldFromTab('Root.Rotator', 'BackgroundImage');
    return $fields;
}

以下是Rotator类的代码：

<?php

class RotatorImage extends DataObject {

    public static $db = array(
        'SortOrder' => 'Int',
        'Header' => 'varchar',
        'Body' => 'HTMLText',
    );

    // One-to-one relationship with gallery page
    public static $has_one = array(
        'Image' => 'Image',
        'BackgroundImage' => 'Image',
        'Page' => 'Page',
        'InternalURL' => 'SiteTree',
    );

    // tidy up the CMS by not showing these fields
    public function getCMSFields() {
        $fields = parent::getCMSFields();
        $fields->removeFieldFromTab("Root.Main","PageID");
        $fields->removeFieldFromTab("Root.Main","SortOrder");
        return $fields;
    }

    // Tell the datagrid what fields to show in the table
    public static $summary_fields = array(
        'ID' => 'ID',
        'Title' => 'Title',
        'Thumbnail' => 'Thumbnail',
        'InternalURLID' => 'Internal URL',
    );

    // this function creates the thumnail for the summary fields to use
    public function getThumbnail() {
        return $this->Image()->CMSThumbnail();
    }

    public function canEdit() {
        return true;
    }

    public function canDelete() {
        return true;
    }

    public function canCreate(){
        return true;
    }

    public function canPublish(){
        return true;
    }

    public function canView(){
        return true;
    }
}

但是这不起作用，我确信我的字段名称是正确的。我试过Root.Rotator.Main＆＃39;和＆＃39; Root.Rotator.Content＆＃39;只是看看会发生什么，那些也没有用。我错过了什么？是否可以通过这种方式隐藏自定义选项卡上的字段，还是需要尝试其他内容？

Answer 1

嗯，您想要隐藏网格域详细信息表单中的字段吗？无法在您的网页getCMSFields()中完成，因为网格负责生成详细信息表单。两种可能的解决方案：

1）告诉网格使用自定义组件隐藏这些字段。我不知道怎么做

2）告诉您的Rotator类仅在相关页面是主页时显示字段：

public function getCMSFields() {
    $fields = parent::getCMSFields();

    //...other stuff....

    $isOnHomePage = ($this->Page() && $this->Page()->ClassName == 'HomePage'); //put in your own classname or conditions

    if(!$isOnHomePage) {
        //remove the fields if you're not on the HomePage
        $fields->removeByName('Body');
        //we need to suffix with "ID" when we have a has_one relation!
        $fields->removeByName('BackGroundImageID'); 
    }
    return $fields;
}

Answer 2

这会有用......

$fields->removeByName('FieldName');

尝试删除/隐藏SilverStripe
