PHPExcel corrupt file Drop down list not working Windows Excel Data validation

Question

If I use:

$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('"male,female"');

to create an excel file, I get the following errors on windows Excel

1. We found a problem with some content in 'filename.xlsx'. Do you want to recover....
2. Removed Feature: Data validation from /xl/worksheets/shee1.xml part

If I comment that code out it opens normally.

Works as expected on Ubuntu Libre Office.

Answer 1

This is all explained in the PHPExcel documentation

And if you look at the examples such as 15datavalidation.php, it demonstrates how to create List type data validations

$objValidation = $objPHPExcel->getActiveSheet()
    ->getCell('B5')
    ->getDataValidation();
$objValidation->setType( PHPExcel_Cell_DataValidation::TYPE_LIST );
$objValidation->setErrorStyle( PHPExcel_Cell_DataValidation::STYLE_INFORMATION );
...
$objValidation->setFormula1('"Item A,Item B,Item C"');

shows how to create a list of fixed values

$objValidation = $objPHPExcel->getActiveSheet()
    ->getCell('B7')
    ->getDataValidation();
$objValidation->setType( PHPExcel_Cell_DataValidation::TYPE_LIST );
$objValidation->setErrorStyle( PHPExcel_Cell_DataValidation::STYLE_INFORMATION );
...
$objValidation->setFormula1('$D$2:$D$6');

shows how to create a list using a formula

Example 39dropdown.php even shows how to created linked lists, where the values in one list are dependent on the selected value of another
