正确的TCA'type'=>'check'的前端映射 [英] Correct frontend mapping of TCA 'type'=>'check'

问题描述

我目前在TYPO3 7/Extbase中实现了一个用户权限对象.按照(简化)将不同的权限映射为INT的位:

I currently implement a user right object in TYPO3 7/Extbase. Different rights are mapped as bits of an INT as per (simplified):

'permissions' => array(
 'label' => 'permissions'
 'config' => array(
  'type' => 'check',
  'items' => array(
   array('Permission 1', ''),
   array('Permission 2', '')
  )
 )
),

在后端中对此所做的修改可以正常工作，并且这些标志已正确地存储为它们在DB中的相应位.

Modification of this in the Backend works flawlessly and the flags are correctly stored as their corresponding bits in he DB.

如何在前端实现类似的行为?是否有(正确)将位值映射到流体复选框的方法?

How can I achieve similar behaviour in the frontend? Is there a (correct) way of mapping the bit values to fluid checkboxes?

推荐答案

您可以添加用于设置或返回位的自定义setter/getter函数.

You can add custom setter/getter functions that set or return the bits.

在您的模型中:

/**
 * @var int
 */
protected $permissions;

添加类似这样的内容:

/**
 * @return int
 */
public function getPermission2() {
  return $this->permissions & 2 > 0 ? 1 : 0;
}

/**
 * @param int $permission2
 */
public function getPermission2($permission2) {
  if ($permission2) {
    $this->permissions = $this->permissions | 2;
  } else {
    $this->permissions = $this->permissions ~ 2;
  }
}

然后，您可以在f:form.checkbox或{object.permission2}中的parameter="permission2"中找到其他流体视图帮助器.

Then you can parameter="permission2" in the f:form.checkbox or {object.permission2} for other fluid viewhelpers.

PS:对于权限1，您需要将2更改为1，对于权限3，它将是4

PS: for permission 1 you need to change the 2 to 1 and for permission 3 it would be 4
