adding timestamp to file while uploading

[eluser]quest13[/eluser]
Hi,

I would like to add a timestamp value attached to file name, so that every filename becomes unique.

I tried in the following way,

$file_name = $_FILES["uploadedfile"]["name"].microtime();

but the file is saved as follows and hence corrupted

test_filename.jpg0.14866500 1252686986

Can anyone help me to solve my problem ?

I want to create each filename with unique name and want to keep the jpg format too.

Any idea ?

Thanks

The CI file upload library adds a number after the filename
of the just uploaded file if a file with the same name
allready exixts. So you don't have to worry about that.

You're adding the time in the wrong spot. The way you're doing is resulting exactly as expected. Flip flop! Oh, and microtime() would not be a good addon for a file name, since it has periods and spaces and such in it. Use time() instead.

Code:

$file_name = time() . $_FILES['uploadedfile']['name'];
