希望有知识的人读到这个。

任务很简单，但出了点问题。我写了一个扩展来为每个页面扩展页面表，并带有一些新的道具。

这些值是： 1 个布尔值（扩展是否处于活动状态） 1 个文本值（例如 css 类名） 1 个文件链接到 sys_file 用于上传的图像

字段本身在后端按预期工作。 后端的字段 但是如果我尝试通过前端的流体访问它们，是否只保存了一个 lony 1 (Int)？

在流体中：{data.tx_mnadditionalpagefields_extended_background_image}

导致这个 -> 1（整数）

我在做什么错？

我的 ext_tables.sql

CREATE TABLE pages (
    tx_mnadditionalpagefields_custom_css_class varchar(255) DEFAULT '' NOT NULL,
    tx_mnadditionalpagefields_activate_extended_rules TINYINT(1) UNSIGNED DEFAULT '0' NOT NULL,
    tx_mnadditionalpagefields_extended_background_image int(11) unsigned NOT NULL default '0'
);

我的分机.../Configuration/TCA/Overrides/pages.php

<?php

defined('TYPO3_MODE') or die();

// Configure new fields:
$fields = [
    'tx_mnadditionalpagefields_custom_css_class' => [

对于图像/文件，本地表仅存储对文件的引用计数。(int)1 表示，有一个参考。

查看 DataProcessing，了解如何将这些文件引用与 Fluid 一起使用： https ://docs.typo3.org/c/typo3/cms-core/master/en-us/Changelog/7.4/Feature-67662-DataProcessorForFiles.html
