TYPO3 EXT:femanager添加下拉选择字段遇类型错误求助

报错信息 #

The argument "options" was registered with type "array", but is of type "string" in view helper "In2code\Femanager\ViewHelpers\Form\SelectViewHelper".

问题场景 #

在TYPO3 V11.5.37 + femanager 7.3.1环境下，扩展femanager自定义字段时添加用户类型下拉选择框，出现上述错误，当前模板调用代码：

<femanager:form.select
  id="femanager_field_usertype"
  property="userType"
  options="{1:private, 2:business, 3:real estate agent}"
  defaultOption="{f:translate(key:'pleaseChoose')}"
  class="form-control"
  additionalAttributes="{femanager:Validation.FormValidationData(settings:settings,fieldName:'userType')}" />

解决方案 #

错误根源是options参数被解析成了字符串，而非要求的数组类型。在Fluid模板中，数组的字符串值必须用单引号包裹，否则会被识别为变量或无效语法。修改后的代码如下：

<femanager:form.select
  id="femanager_field_usertype"
  property="userType"
  options="{1:'private', 2:'business', 3:'real estate agent'}"
  defaultOption="{f:translate(key:'pleaseChoose')}"
  class="form-control"
  additionalAttributes="{femanager:Validation.FormValidationData(settings:settings,fieldName:'userType')}" />

仅需给每个选项值添加单引号'，即可让Fluid正确解析为数组类型。
