如何在 TYPO3 中嵌套 SplitProcessors？

  • 772

我需要按行拆分字符串，然后按|。

最初，我使用了一个与简单字符串一起工作的CommaSeparatedValueProcessor函数fieldDelimiter = |，但是现在字符串包含"和'用于测量，这使其无法工作。

我尝试设置fieldEnclosure其他值，"但似乎没有帮助。

所以我想我可以退回到SplitProcessor。有没有办法嵌套它来获得 2 个分割？

dataProcessing {
    10 = TYPO3\CMS\Frontend\DataProcessing\SplitProcessor
    10 {
        fieldName = data
        delimiter.char = 10
        as = myarray
    }
}

    我认为 SplitProcessor 嵌套是不行的。
    所以唯一的办法就是实现一个自定义的 dataProcessor。不过这没什么大不了的。

    EXT:你的扩展/类/数据处理/CustomSplitProcessor

    <?php

namespace VENDOR\YourExtension\DataProcessing;

use TYPO3\CMS\Core\Utility\GeneralUtility;
use TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer;
use TYPO3\CMS\Frontend\ContentObject\DataProcessorInterface;

class CustomSplitProcessor implements DataProcessorInterface
{

    public function process(ContentObjectRenderer $cObj, array $contentObjectConfiguration, array $processorConfiguration, array $processedData)
    {
        if (isset($processorConfiguration['if.']) && !$cObj->checkIf($processorConfiguration['if.'])) {
            return $processedData;
        }

        // The field name to process
        $fieldName = $cObj->stdWrapValue('fieldName', $processorConfiguration);
        if (empty($fieldName)) {
            return $processedData;
        }

        $originalValue = (string)($cObj->data[$fieldName] ?? '');

        // Set the target variable
        $targetVariableName = $cObj->stdWrapValue('as', $processorConfiguration, $fieldName);

        // Remove empty entries
        $removeEmptyEntries = (bool)$cObj->stdWrapValue('removeEmptyEntries', $processorConfiguration, false);

        // Set the firstDelimiter which is "LF" by default
        // Set the secondDelimiter which is "|" by default
        $firstDelimiter = (string)$cObj->stdWrapValue('firstDelimiter', $processorConfiguration, LF);
        $secondDelimiter = (string)$cObj->stdWrapValue('secondDelimiter', $processorConfiguration, '|');

        $splitArray = GeneralUtility::trimExplode($firstDelimiter, $originalValue, $removeEmptyEntries);

        foreach ($splitArray as $splitItem)
        {
            $processedData[$targetVariableName][$splitItem] = GeneralUtility::trimExplode($secondDelimiter, $splitItem, $removeEmptyEntries);
        }

        return $processedData;
    }
}

    在此示例中，第一个分隔符是LF(new-Line)，第二个分隔符是|。因此，您无需在 TypoScript 中根据情况设置分隔符。

    然后您可以像这样使用 DataProcessor：

    dataProcessing {
  10 = VENDOR\YourExtension\DataProcessing\CustomSplitProcessor
  10 {
    fieldName = data
    as = myarray
  }
}
