Rename if file exists on upload

[NathanLedet]

I have an upload script and I'm wondering how I check to see if the file exists on the server already, and if so, append a 01 or 02 (if there is a 01).  Thanks for any advice

You could use a while loop. Split the extension from the file name then append an integer and the extension

 

I didn't test this but i think you'll get the general idea:

 

<?php
// This should keep checking until the file doesn't exists
while( file_exists($YourFile) {
  $Count += 1;
  $YourImageFile = $FileName . $Count . $Extension;
}
?>

This may be long, but it should work...

 

$file = 'location/of/your/file.jpg';

$pos = strrpos($file,'.');
$ext = substr($file,$pos); 
$dir = strrpos($file,'/');
$dr  = substr($file,0,($dir+1)); 

$arr = explode('/',$file);
$fName = trim($arr[(count($arr) - 1)],$ext);


$exist = FALSE;
$i = 0;
while(!$exist){
     if(file_exists($file.$i)||file_exists($file)){
          continue;
     }else{
          $exist = TRUE;
          $file = $dr.$fName.$i.$ext;
     }
     $i++;
}

echo $file;
// Upload Script Here

how do i then rename the file before copying? automatically?

[uberweiss]

i mean, i can't get either of them to work... what am i doing wrong...

 

i made this:

 

where should i paste in the code?

 

<?php

 

$path = "C:\web\www-root\www.eurogiro.com\html\joomla\upload";//Sti til mappen filen skal uploades i!

$filename = "coc.xls";//Filens navn

 

 

 

if(count($_POST)>0)//Der bliver postet til scriptet

{

    $file = $_FILES['file'];

   

   

   

    if(move_uploaded_file($file['tmp_name'], $path."/".$filename))

    {

        echo 'The file has been succesfully uploaded';

    }

    else

    {

        echo 'The file wasnt uploaded. Please try again';

    }

}

else

{

$form = '<form enctype="multipart/form-data" action="" method="post">

<input type="file" name="file" value=""><br>

<input type="submit" name="submit" value="Upload">

</form>';

echo $form;

}

echo "</body>

</html>";

?>

rename("/path/older_file.ext", "/path/new_filename.ext");

Check if the file exists before uploading, if exists rename with the new generated name. I guess this should work

$file_path = $path."/".$filename
if (file_exists($filepath)) {
   /*generate the $new_file_path, with the code given you before*/
   rename($filepath,$new_file_path);
}

if(move_uploaded_file($file['tmp_name'], $path."/".$filename))
    {
        echo 'The file has been succesfully uploaded';
    }
    else
    {
        echo 'The file wasnt uploaded. Please try again';
    }

thanks alot...

 

the only problem now is that i hardcode the "new file name" i would like if the file exists call the file filename1 and if filename1 exists then filename2 and if filename2 exist then filename3 and so on...
