Need help adding a timestamp to my filename/variable

Posted on 16th Feb 2014 07:03 pm by admin

Hello,

I'm kind of stupid when it comes to php and I need a tiny bit of help. I've got a form/php setup that allows a user to upload an image to my server. The upload is working well, and the code is functioning as is, however, I would like to add a timestamp to the file name before it is saved to the server, as well as making sure the time stamped file name is turned into a variable I can recall on a later php page. This is all in an effort to create unique filenames for uploaded content.

Here is my current form code:

<FORM ENCTYPE="multipart/form-data" ACTION="uploadck.php" METHOD=POST>
Upload this file: <INPUT NAME="file_up" TYPE="file">
<INPUT TYPE="submit" VALUE="Send File"></FORM>

and here is the php for that form:

<?
$file_upload="true";
$file_up_size=$_FILES['file_up'][size];
echo $_FILES[file_up][name];
if ($_FILES[file_up][size]>1000000){$msg=$msg."Your uploaded file size is more than 1MB so please reduce the file size and then upload. Visit the help page to know how to reduce the file size.<BR>";
$file_upload="false";}

if (!($_FILES[file_up][type] =="image/jpeg" OR $_FILES[file_up][type] =="image/gif")){$msg=$msg."Your uploaded file must be of JPG or GIF. Other file types are not allowed<BR>";
$file_upload="false";}

$file_name=$_FILES[file_up][name];
$add="upload/$file_name"; // the path with the file name where the file will be stored, upload is the directory name.
if($file_upload=="true"){

if(move_uploaded_file ($_FILES[file_up][tmp_name], $add)){
echo "Congratulations, file succesfully uploaded";
}else{echo "Failed to upload file Contact Site admin to fix the problem";}

}else{echo $msg;}
?>
