Blank document when downloading word file just created. - Shawn - 06-09-2016

Using PHPWord I load a template from my public directory:

Code:
$templateProcessor = new \PhpOffice\PhpWord\TemplateProcessor(asset_url() . 'templates/receipt_template.docx');

I generate a file name and set headers for downloading the file:

Code:
$datetime = date('Y_M_d_G_i');

$filename = 'receipt_' . $datetime . '.docx';

header("Content-Description: File Transfer");

header('Content-Disposition: attachment; filename="' . $filename . '"');

header('Content-Type: application/vnd.openxmlformats-officedocument.wordprocessingml.document');

header('Content-Transfer-Encoding: binary');

header('Cache-Control: must-revalidate, post-check=0, pre-check=0');

header('Expires: 0');

I save the template as a new docx file (no changes for now) to the same directory. This works. I can see the new file in the public html directory and it has all the content of the template

Code:
$templateProcessor->saveAs(set_realpath('assets/templates/' . $filename));

This code downloads a word file, but the file is blank:

Code:
force_download(set_realpath('assets/templates/' . $filename, NULL, TRUE));

The above code resides in one controller. Is it a problem with opening a new filehandle before the other one is closed?

If a file is open it cannot be modified.

How do I ensure that the file has been closed after the TemplateProcessor->saveAs statement, before attempting the force_download?

This is the solution I arrived at:
I created as directory structure at the same level of the application and system directory (outside the public html)
assets\templates\receipt_template.docx
assets\receipts\

In my model:

Code:
// delete any previous files created and downloaded, first

$this->delete_receipt('../assets/receipts');

//create TemplateProcessor object with word doc

$templateProcessor = new \PhpOffice\PhpWord\TemplateProcessor('../assets/templates/receipt_template.docx');

// make substitutions

$templateProcessor->setValue('name', htmlspecialchars('Elementary School Teachers Federtion of Ontario', ENT_COMPAT, 'UTF-8'));

$templateProcessor->setValue('amount', htmlspecialchars('35.50', ENT_COMPAT, 'UTF-8'));

// generate file name and save in receipts directory

$datetime = date('Y_M_d_G_i');

$filename = 'receipt_' . $datetime . '.docx';

$templateProcessor->saveAs('../assets/receipts/' . $filename);

//download

force_download('../assets/receipts/' . $filename, NULL, TRUE);
