How to rewrite the code by naming the image with the upload time



If (is_uploaded_file ($ _ FILES ['upfile'] ['tmp _ name']) {

$ Upfile = $ _ FILES ["upfile"];

$ Name = $ upfile ["name"];
$ Type = $ upfile ["type"];
$ Size = $ upfile ["size"];
$ Tmp_name = $ upfile ["tmp_name"];
$ Error = $ upfile ["error"];


Switch ($ type ){
Case 'image/pjpeg ': $ OK = 1;
Break;
Case 'image/jpeg ': $ OK = 1;
Break;
Case 'image/GIF': $ OK = 1;
Break;
Case 'image/png ': $ OK = 1;
Break;
}

If ($ OK & $ error = '0 '){
Move_uploaded_file ($ tmp_name, 'up/'. $ name );
Echo "uploaded successfully ";
Echo "$ name
";
Echo "$ type
";
Echo "$ size
";
Echo "$ tmp_name
";


}
}

------ Solution --------------------
I seem to remember which post you asked this question? I wanted to answer your question this afternoon. Why did you send it here?
What time does your time mean? Timestamp?

Modify here
// Move_uploaded_file ($ tmp_name, 'up/'. $ name );
// Get the file extension
$ Oldname = $ upfile ['name']; // note the inclusion path.
$ Fileexpand = pathinfo ($ oldname, PATHINFO_EXTENSION );
$ Filename = strtotime (); // Time stamp
// $ Filename = date ('ymmdgis '); // Beijing time
Move_uploaded_file ($ tmp_name, 'up/'. $ filename. $ fileexpand );

------ Solution --------------------
Move_uploaded_file ($ tmp_name, 'up/'. $ filename. $ fileexpand );

Here the error is changed
Move_uploaded_file ($ tmp_name, 'up/'. $ filename.'. '. $ fileexpand );

The code above is what you want

There is another question: Preview the image.
You can use JavaScript to control a hidden div to read the image and assign the file name to js after uploading...
Maybe you cannot understand ....
