TYPO3技术咨询：复用pageSetup.ts后能否删setup.ts配置及无控制器扩展的Fluid调用

Q2: 无控制器的TYPO3扩展，如何在后端布局的Fluid模板中调用constants.ts里的配置？ #

Since your extension doesn’t have a controller, you don’t have a plugin context to pull settings from directly. But there are three straightforward ways to make this work:

Method 1: Mirror the setting to a global TypoScript variable

This is the simplest approach. Update your extension’s setup.ts to copy the plugin setting into a global page variable accessible in backend layouts:

# In your extension's setup.ts
page.siteClaim = {$plugin.tx_rmbase.settings.siteClaim}

Then access it in your backend layout Fluid template like this:

{TSFE.config.page.siteClaim}

Method 2: Inject the variable directly into your backend layout config

If you define backend layouts via TypoScript, inject the setting as a template variable directly in the layout definition. Add this to your extension’s setup.ts:

page.backend_layouts {
    # Replace with your backend layout key/name
    my_custom_layout {
        title = My Backend Layout
        config {
            # Your existing backend layout grid config here
            backend_layout {
                colCount = 1
                rowCount = 1
                rows {
                    1 {
                        columns {
                            1 {
                                name = Main Content
                                colPos = 0
                            }
                        }
                    }
                }
            }
        }
        # Path to your backend layout Fluid template
        template = EXT:rmbase/Resources/Private/Layouts/Backend/MyLayout.html
        # Inject the setting as a template variable
        variables {
            siteClaim = {$plugin.tx_rmbase.settings.siteClaim}
        }
    }
}

Now you can use {siteClaim} directly in your Fluid template—no extra code needed.

Method 3: Build a custom ViewHelper (for flexibility)

If you need to access multiple settings or want a reusable solution, create a simple ViewHelper to fetch TypoScript values:

1. Create the ViewHelper class in your extension:

<?php
namespace MonTea\Rmbase\ViewHelpers;

use TYPO3\CMS\Core\Utility\GeneralUtility;
use TYPO3\CMS\Core\Configuration\TypoScript\TypoScriptService;
use TYPO3Fluid\Fluid\Core\ViewHelper\AbstractViewHelper;

class GetTypoScriptSettingViewHelper extends AbstractViewHelper
{
    public function initializeArguments()
    {
        $this->registerArgument('path', 'string', 'TypoScript path to the setting (e.g. plugin.tx_rmbase.settings.siteClaim)', true);
    }

    public function render()
    {
        $typoScriptService = GeneralUtility::makeInstance(TypoScriptService::class);
        // Get the full TypoScript setup
        $fullTypoScript = isset($GLOBALS['TSFE']) ? $GLOBALS['TSFE']->tmpl->setup : [];
        $plainTypoScript = $typoScriptService->convertTypoScriptArrayToPlainArray($fullTypoScript);
        
        // Fetch the value using the provided path
        return \TYPO3\CMS\Core\Utility\ArrayUtility::getValueByPath($plainTypoScript, $this->arguments['path'], '.');
    }
}

2. Use it in your Fluid template:

{namespace rmbase=MonTea\Rmbase\ViewHelpers}
<p>{rmbase:getTypoScriptSetting(path: 'plugin.tx_rmbase.settings.siteClaim')}</p>

Note: For backend contexts, you might need to ensure $GLOBALS['TSFE'] is initialized—if you run into issues, you can add code to initialize it manually, but the first two methods are usually easier for backend layouts.
