Please I am new to php and I have not been able to figure out why this code is not working. I tried downloading this docx file however, it downloads the file but when I open the file, nothing shows on the file. It is empty. I believe the file is corrupted and this is due to the code. The code is below:
<?php if(isset($_POST['file_name'])) { $file = $_POST['file_name']; echo $file; header('Content-Description: File Transfer'); header('Content-Type: application/vnd.openxmlformats-officedocument.wordprocessingml.document'); header('Content-Disposition: attachment; filename='.$file.''); header('Content-Transfer-Encoding: binary'); header('Expires: 0'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); header('Content-Length: ' . filesize($file)); ob_clean(); flush(); readfile('resumeFolder/'.$file); exit(); }?><form action="force_download.php" method="post" name="downloadform"><input name="file_name" value=" Aunt_CC_Letter.docx" type="hidden"><input type="submit" value="Download the MP3"></form>
