使用 Typoscript 访问 DCE（动态内容元素）创建的字段

Question

在一个项目中，我正在使用 TYPO3 扩展 DCE（动态内容元素）。使用 DCE，您无需编写扩展程序即可创建自己的动态内容元素。

创建内容对象后，您可以使用 FLUID 访问创建的内容元素。

到目前为止一切顺利。一切都很完美。

现在我的问题：

我需要像这样使用 Typoscript 访问 DCE 中的变量：

10 = TEXT
10 {
    field = referenceCustomer
    wrap = <span class="referenceCustomer">|</span>
}

字段referenceCustomer 之前由DCE 创建。使用 FLUID，我可以访问该字段

{field.referenceCustomer}

我真的不知道如何访问生成的字段..

但真正令人困惑的是，我能够访问我在 Typoscript 中使用 DCE 创建的 FAL Image 字段..

此代码有效：

10 = FILES
10 {

    references {
        table = tt_content
        uid.field = uid
        fieldName = referenceImages
    }

    begin = 0
    maxItems = 1

    renderObj = IMAGE
    renderObj {

        file {
            import.data = file:current:uid
            treatIdAsReference = 1
            width = 365c
            height = 125c
        }                                    

        altText.data = file:current:title
        titleText.data = file:current:title
    }

}

也许你可以帮助我.. 只见树木不见树林..

为了将此问题标记为已解决，我将自己发布答案。

我做了一个 PHP Userfunc。 UserFunc 能够读取 FlexForm 值。

这是我的解决方案：

Typoscript 对象：

includeLibs.FlexformValue =  fileadmin/templates/Utility/UserFunc/FlexformValue.php

5 = USER
5 {
    userFunc = FlexformValue->field
    userFunc {

        uid = TEXT
        uid {
            field = uid
        }

        field = referenceCustomer

    }

}

以及所需的 PHP UserFunc：

    function field($content, $conf) {

        $conf = $conf['userFunc.'];

        $res = $GLOBALS['TYPO3_DB']->exec_SELECTquery('pi_flexform', 'tt_content', 'uid = ' . $uid);

            }
            elseif (is_array($value) && array_key_exists('el', $value)) {
                $propertyName = substr($key, 9);

                            if (is_array($entry)) {
                                foreach($entry as $k => $v) {
                                    $entry[$k] = $v['vDEF'];
                                }
                                $values[$i++] = array('container_' . $propertyName => $entry);
                            }
                        }
                    }
                }
                $caller->temporaryDceProperties[$propertyName] = $values;
            } elseif (is_array($value)) {
                $this->getVDefValues($value, $caller, $key);
            }
        }
    }

}

我希望这个答案能帮助和我有同样问题的人..

问题解决了。
