php file upload overwrite

hello -

i'm using some commercial php upload script that i purchased years ago.

the problem is it won't allow me to overwrite my images which i have to do for this particular application - it just creates new ones.

don't know a lot about php upload so i tried throwing an $overwrite=true variable in the code for kicks and nothing changed. here's the way the code for the variables:

// *** BEGIN Simply Upload ***
require_once("FXInc/uploadAction.inc");
$errMsg = "";
$action = true;
$noPath = true;
$rename = false;
$delete = false;
$overwrite = true;
$FX_successRedirect = "";
$FX_DirPath = "../images/ba/".$thumbs_dir."/thumbs/";
$FX_typearray = array("application","audio","image");
$FX_extarray = array();
$FX_size = "";
$FX_fields = array();
if ((isset($HTTP_POST_VARS["FX_upload"])) && ($HTTP_POST_VARS["FX_upload"] == "form1")) {
  require_once("FXInc/upload.inc");
}
// *** END Simply Upload ***

well it look like the code you have has few years ;). The $HTTP_POST_VARS variable is deprecated for long time ;). Maybe you should consider pay someone to wrote or modify your script :).
But back to the point. You have to show us a little bit more of your code, fragment you show us is too small. We can't predict problem just from definition of variables ;)

thanks for taking a look at this szewkam:

this file looks relevant:

<?php
function renameIt($name,$path) {
  $re = "/\(\d+\)/";
  if (preg_match($re,$name,$matches)) {
    $num = substr($matches[0],1,strlen($matches[0])-2);
    $newName = preg_replace($re,"(".(++$num).")",$name);
  } else {
    $newName = str_replace(".","(1).",$name);
  }
  if (file_exists($path . $newName)) $newName = renameIt($newName,$path);
  return $newName;
}
 
$FX_uploadAction = $HTTP_SERVER_VARS['PHP_SELF'];
if (isset($HTTP_SERVER_VARS['QUERY_STRING'])) {
  $FX_uploadAction .= "?" . htmlentities($HTTP_SERVER_VARS['QUERY_STRING']);
}
?>

Hi phillystyle123,

if you want to overwrite the file everytime, you can simply make a small change to the rename function,
like this:

function renameIt($name,$path) {

  return $name; // amendment: don't rename  -- phillystyle123, [date]

  $re = "/\(\d+\)/";

  [...]
}

Make sure that the file is writable. If there are problems with overwriting the file,
you can have the old one deleted beforehand:

function renameIt($name,$path) {

  unlink($path . $newName);
  return $name; // amendment: don't rename  -- phillystyle123, [date]

  $re = "/\(\d+\)/";

  [...]
}

Best,

[Webinar] Kill tickets & tabs using PowerShell

Are you tired of cycling through the same browser tabs everyday to close the same repetitive tickets? In this webinar JumpCloud will show how you can leverage RESTful APIs to build your own PowerShell modules to kill tickets & tabs using the PowerShell command Invoke-RestMethod.

you can also find a file where function renameIt is called, and just comment line with it or remove the call :)

thanks guys - solutionDriver - can you show me where your code would fit into my code?

this is what i'm guessing:
<?php
function renameIt($name,$path) {
unlink($path . $newName);
  return $name; // amendment: don't rename  -- phillystyle123, [date]
 
  $re = "/\(\d+\)/";
  $re = "/\(\d+\)/";
  if (preg_match($re,$name,$matches)) {
    $num = substr($matches[0],1,strlen($matches[0])-2);
    $newName = preg_replace($re,"(".(++$num).")",$name);
  } else {
    $newName = str_replace(".","(1).",$name);
  }
  if (file_exists($path . $newName)) $newName = renameIt($newName,$path);
 }
 
$FX_uploadAction = $HTTP_SERVER_VARS['PHP_SELF'];
if (isset($HTTP_SERVER_VARS['QUERY_STRING'])) {
  $FX_uploadAction .= "?" . htmlentities($HTTP_SERVER_VARS['QUERY_STRING']);
}
?>

You may need to change $delete = false; to $delete = true; and to make sure that there is enough permissions for deletion. Overwrite is simply delete then create new.
