Mast3r Betty Posted December 20, 2006 Share Posted December 20, 2006 Hello, I just got into uploading images onto my website, and ran into a little problem with the file names being unique. How would I make it so that when a file is uploaded, it is renamed to a random number (or something equal)?I'm using this nice code from W3; <?phpif (($_FILES["file"]["type"] == "image/gif")|| ($_FILES["file"]["type"] == "image/jpeg")&& ($_FILES["file"]["size"] < 20000)) { if ($_FILES["file"]["error"] > 0) { echo "Return Code: " . $_FILES["file"]["error"] . "<br />"; } else { echo "Upload: " . $_FILES["file"]["name"] . "<br />"; echo "Type: " . $_FILES["file"]["type"] . "<br />"; echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />"; echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />"; if (file_exists("upload/" . $_FILES["file"]["name"])) { echo $_FILES["file"]["name"] . " already exists. "; } else { move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $_FILES["file"]["name"]); echo "Stored in: " . "upload/" . $_FILES["file"]["name"]; } } }else { echo "Invalid file"; }?> Thank you. Link to comment Share on other sites More sharing options...
Lulzim Posted December 20, 2006 Share Posted December 20, 2006 you can specify a new name in the move_uploaded_file functionthe second argument of the move_uploaded_file is the destination folder and the file name, so just add a random number move_uploaded_file($_FILES["file"]["tmp_name"],"upload/" .rand(1.999). $_FILES["file"]["name"]); just be careful not to add the random numbers in the end of the file name, because a picture lets say somepicture.jpg would be somepicture.jpg3213132 and you will not be able to display that picture in your web page Link to comment Share on other sites More sharing options...
