使用phpexcel填充下拉菜单
我遇到了以下问题。
我试图从我的数据库中得到一些结果，我想将结果插入到下拉列表中。
在检验文件中是以下示例：
$objValidation->setFormula1('"Item A,Item B,Item C"');
所以结果必须用逗号分隔，总的结果必须在“”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);
有人有一个想法，为什么dropdownlist不会填充？
提前致谢！

这是正确的工作代码：
<?php error_reporting(E_ALL); ini_set('display_errors', TRUE); ini_set('display_startup_errors', TRUE); define('EOL',(PHP_SAPI == 'cli') ? PHP_EOL : '<br />'); require_once dirname(__FILE__) . './PHPExcel.php'; echo date('H:i:s') , " Create new PHPExcel object" , EOL; $objPHPExcel = new PHPExcel(); $objPHPExcel->setActiveSheetIndex(0); $objPHPExcel->getActiveSheet() ->setCellValue('B5', "SELECT ITEM") ; $configs = "DUS800, DUG900+3xRRUS, DUW2100, 2xMU, SIU, DUS800+3xRRUS, DUG900+3xRRUS, DUW2100"; $objValidation = $objPHPExcel->getActiveSheet()->getCell('B5')->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.'"'); // Set active sheet index to the first sheet, so Excel opens this as the first sheet $objPHPExcel->setActiveSheetIndex(0); // Save Excel 95 file echo date('H:i:s') , " Write to Excel5 format" , EOL; $callStartTime = microtime(true); $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); $objWriter->save('populate.xls'); ?>
它将会输出到与这个脚本相同的目录中的populate.php 。
首先，它不是setFormula1("'".$configs."'") 。 它是setFormula1('"'.$configs.'"') 。
其次，你可能会错过其他地方，这就是为什么你得到ERR_CONNECTION_RESET 。 我发布了一个工作示例，以防万一您在代码中丢失了其他内容。 如果你已经发布了整个代码，我可以肯定知道。
改变线
$objValidation->setFormula1($configs);
至
$objValidation->setFormula1("'".$configs."'");
因为在结构中的数据是用单引号（'）。
示例工作代码
$objValidation2 = $sheet -> getCell('E1') -> getDataValidation(); $objValidation2 -> setType(PHPExcel_Cell_DataValidation::TYPE_LIST); $objValidation2 -> setErrorStyle(PHPExcel_Cell_DataValidation::STYLE_INFORMATION); $objValidation2 -> setAllowBlank(true); $objValidation2 -> setShowInputMessage(true); $objValidation2 -> setShowErrorMessage(true); $objValidation2 -> setShowDropDown(true); $objValidation2 -> setErrorTitle('Invalid date'); $objValidation2 -> setError('Date is not in list.'); $objValidation2 -> setPromptTitle('Select DOB date'); $objValidation2 -> setPrompt('Please pick a date from the drop-down list.'); $dates = '"01,02,03,04,05,06,07,08,09,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31"'; $objValidation2 -> setFormula1("'".$dates."'");
