Populate dropdown with phpexcel

Question

I'm running into the following problem.

Im trying to get some results from my database and I want to insert the results into a dropdown list.

In the examle file was the following example:

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

so the results have to be comma seperated and the total results have to be between "".

Here is the code so far:

$configurations = Db::getInstance()->queryResults('SELECT * FROM configurations', array($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);  

Anybody has an idea why the dropdownlist does not get populated??

Thanks in advance!

Answer 1

Here is the correctly working code:

<?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');
?>

It will output to populate.php in the same directory as this script.

First off, it's not setFormula1("'".$configs."'"). It's setFormula1('"'.$configs.'"').

Secondly, you might be missing something elsewhere, which is why you are getting ERR_CONNECTION_RESET. I posted a working example just in case you are missing something else in the code as well. If you had posted the entire code, I could have known for sure.
