Why is the file not being sent by mail?

Question

PHP

Hello. Please help. The site has a form for vacancies. All fields work. It was required to send a text file with a resume. It seems that everything was done correctly, but when sending data from the form (if we uploaded a file), an error appears. Without downloading the file, everything works. Console error "Swift_IoException in FileByteStream.php line 144: Unable to open file for reading".The file is stored in a temporary folder and is not saved after sending (this is what I need). I tried to upload the file to the server and, when sending mail, manually enter the path to the file for attach("/server folders/tmp/php/uploads/phpfoeu5Y/resume.docx"), then the file is attached and comes to the mail. But if I put the same path into the variable $path = "/server folders/tmp/php/uploads/phpfoeu5Y/resume.docx"; and output attach($path) then it will give me an error. Please help me point out my mistake.

Answer 1

$path = $_FILES["file"]["tmp_name"].'/'.$_FILES["file"]["name"];
well, what do you have here?
