Image Upload With Date (PHP)

[realm]

Hi,

I have made a script to handle an image upload and want the date to be in front of the image name when uploaded but does not seem to put the date in front and just uploads the image without the date in front. But all the code looks fine to me. I think i have been looking at it for too long tbh and will be something very easy.

$date = time("DMY",strtotime("now"));

if($_POST['action']=='Add Entry'){
    //handle image upload
    if(is_uploaded_file($_FILES['image']['tmp_name']) && move_uploaded_file($_FILES['image']['tmp_name'], './images/'.$_FILES['image']['name']) && $_FILES['image']['size']<(1024*100)){
        $imagefile = './images/'.$date.$_FILES['image']['name'];
    }

The time function does not accept any parameters. Check the PHP manual.

Indeed it doesn't take any parameters. It's the date() function which takes either one or two parameters.

Sorry i should have posted back i sorted this out the same day. It should have been:

$date = date("dmY",strtotime("now"));

if($_POST['action']=='Add Entry'){
    //handle image upload
    if(is_uploaded_file($_FILES['image']['tmp_name']) && move_uploaded_file($_FILES['image']['tmp_name'], './images/'.$date.$_FILES['image']['name']) && $_FILES['image']['size']<(1024*100)){
        $imagefile = './images/'.$date.$_FILES['image']['name'];

What are the contents of $date? Also, there's no need for the second parameter in the date function - if you want the time now, then you just leave out the second parameter i.e.

$date = date("dmY")

Unless, of course, that's supposed to be $now.

I'm assuming it works now?

Also, it's usually best to include the seconds and/or milliseconds to make it more unique. It depends if it's for multiple users, because two users on the same day could upload an image with the same filename which would break it.

Very good point Kezzer has made. Personally I would use a function such as flock - http://uk2.php.net/manual/en/function.flock.php
