I am trying to upload a doc file from a form and send it to email. I am using
$_FILES['file']['tmp_name'];
The problem is, it is returning a randomly generated file name. So, when it reaches the inbox, the filename is phpvwRGKN.dat (filename is random each time).
How can I preserve the filename and extension?
Note: I am using geekMail class
This question is related to
php
$_FILES['file']['tmp_name']; will contain the temporary file name of the file on the server. This is just a placeholder on your server until you process the file
$_FILES['file']['name']; contains the original name of the uploaded file from the user's computer.
Just a suggestion, but you might try the Pear Mail_Mime class instead.
http://pear.php.net/package/Mail_Mime/docs
Otherwise you can use a bit of code. Gabi Purcaru method of using rename() won't work the way it's written. See this post http://us3.php.net/manual/en/function.rename.php#97347 . You'll need something like this:
$dir = dirname($_FILES["file"]["tmp_name"]);
$destination = $dir . DIRECTORY_SEPARATOR . $_FILES["file"]["name"];
rename($_FILES["file"]["tmp_name"], $destination);
$geekMail->attach($destination);
Like @Gabi Purcaru mentions above, the proper way to rename and move the file is to use move_uploaded_file(). It performs some safety checks to prevent security vulnerabilities and other exploits. You'll need to sanitize the value of $_FILES['file']['name'] if you want to use it or an extension derived from it. Use pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION) to safely get the extension.
$_FILES["file"]["name"] - the name of the uploaded file
$_FILES["file"]["tmp_name"] contains the actual copy of your file content on the server while
$_FILES["file"]["name"] contains the name of the file which you have uploaded from the client computer.
If you wanna get the uploaded file name, use $_FILES["file"]["name"]
But If you wanna read the uploaded file you should use $_FILES["file"]["tmp_name"], because tmp_name is a temporary copy of your uploaded file and it's easier than using
$_FILES["file"]["name"] // This name includes a file path, which makes file read process more complex
