我遇到了以下问题.

我试图从我的数据库中获得一些结果,我想将结果插入下拉列表.

在examle文件中有以下示例:

$objValidation->setFormula1('"Item A,Item B,Item C"');

所以结果必须以逗号分隔,总结果必须在""之间.

这是迄今为止的代码:

$configurations = Db::getInstance()->queryResults('SELECT * FROM configurations', array($siteNumber));
$objPHPExcel->getActiveSheet()->setCellValue('B7', "List:");

$configs = '"';
foreach($configurations as $config) {
    $configs .= $config->configuration_name . ', ';
}
$configs .= '"';

$objValidation = $objPHPExcel->getActiveSheet()->getCell('B8')->getDataValidation();
$objValidation->setType( PHPExcel_Cell_DataValidation::TYPE_LIST );
$objValidation->setErrorStyle( PHPExcel_Cell_DataValidation::STYLE_INFORMATION );
$objValidation->setAllowBlank(false);
$objValidation->setShowInputMessage(true);
$objValidation->setShowErrorMessage(true);
$objValidation->setShowDropDown(true);
$objValidation->setErrorTitle('Input error');
$objValidation->setError('Value is not in list.');
$objValidation->setPromptTitle('Pick from list');
//$objValidation->setPrompt('Please pick a value from the drop-down list.');
$objValidation->setFormula1($configs);  

任何人都知道为什么下拉列表没有填充？

提前致谢!

我刚刚安装了 Python 开始尝试使用 Scrapy。找到了一个首先安装 Miniconda 的教程，这样我就可以安装 Scrapy。现在的问题是我尝试运行的软件也需要 Twisted。所以我用pip安装了twisted。

Twisted 似乎已正确安装，但在运行脚本时仍然出现错误，提示找不到 Twisted 模块。
