Add time to file upload name

Hello.
i have a script for upload file. this script has a problem with duplicate names, in upload folder. i want rename file name in upload folder. i want add date and time after file name when uploaded. how can i do it?
for example file name is 'abc.jpg'. i want rename file name after uploaded in upload folder to: abc' + '$time'.jpg.

Code: Select all

$time = date("H:i:s", time()+$timezone); old name=abc.jpg new name= abc $time.jpg
- php script:

Code: Select all

<?php $allowedExts = array("gif", "jpeg", "jpg", "png"); $temp = explode(".", $_FILES["file"]["name"]); $extension = end($temp); if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/jpg") || ($_FILES["file"]["type"] == "image/pjpeg") || ($_FILES["file"]["type"] == "image/x-png") || ($_FILES["file"]["type"] == "image/png")) && ($_FILES["file"]["size"] < 20000) && in_array($extension, $allowedExts)) { if ($_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"; } ?>

Hello,
See if this script is useful and try addapt it in your code.

Code: Select all

$time = date('H-i-s', time()); $name ='abc.jpg'; $extension ='jpg'; $name = preg_replace('/(.+?)\.'. $extension .'$/i', '$1_'. $time .'.'. $extension, $name); echo $name; // abc_19-39-11.jpg

Hello.
the above mentioned script works great, but it does not work with this:

Code: Select all

$timezone = 0; $now = date("Y-m-d", time()+$timezone); $time = date("H:i:s", time()+$timezone); $time2=$now.'-'.$time; $name = preg_replace('/(.+?)\.'. $extension .'$/i', '$1_'. $time2 .'.'. $extension, $name);
and it show this message:

Code: Select all

Warning: move_uploaded_file(upload/abc_2016-11-16-17:04:29.jpg): failed to open stream: Invalid argument in C:\xampp\htdocs\upload\upload_file.php on line 47 Warning: move_uploaded_file(): Unable to move 'C:\xampp\tmp\phpA075.tmp' to 'upload/abc_2016-11-16-17:04:29.jpg' in C:\xampp\htdocs\upload\upload_file.php on line 47
and it can not move file to upload folder!

The character ":" is not allowed in file name; so, you should replace it with "-" or "_" in the string with the time.

Code: Select all

$time = date("H-i-s", time()+$timezone);
