image uploading script

deathadder · May 9, 2012

ok i have a image uploading script here, it works fine but theres one thing im unhappy with

when i first downloaded it it had 1 working one, and the rest examples which you basically have to put together yourself with the sample code (doesen't work without adding missing coding), i have done all that then i took the time to add a random string prefix, im new at php so it took me awhile to work out which strings would work in the right area.

now this is what i need help with, when it uploads it has two options, download and remove, these both work fine, but on the file uploader that does work it has "file uploaded to "http://site.com/image.png" the example of course did not work (had loading bar working, and etc but didn't upload or have the feature i just mentioned) and the coder of the script used javascript and inner html for the file uploaded.... etc, because it uploads without refreshing, only thing is i cant seem to get it to work with the new random string i put in, i tried to recreate one with the same type of thing they used for the filename but it didn't work

well here is the code, hope you can help.

image upload handler

<?php require_once "phpuploader/include_phpuploader.php" ?>
<?php

$uploader=new PhpUploader();

if(@$_GET["download"])
{
$fileguid=$_GET["download"];
$mvcfile=$uploader->GetUploadedFile($fileguid);
header("Content-Type: application/oct-stream");
header("Content-Disposition: attachment; filename=\"" . $mvcfile->FileName . "\"");
readfile($mvcfile->FilePath);
}

if(@$_POST["delete"])
{
$fileguid=$_POST["delete"];
$mvcfile=$uploader->GetUploadedFile($fileguid);
unlink($mvcfile->FilePath);
echo("OK");
}

if(@$_POST["guidlist"])
{
$guidarray=explode("/",$_POST["guidlist"]);

//OUTPUT JSON

echo("[");
$count=0;
foreach($guidarray as $fileguid)
{
	$mvcfile=$uploader->GetUploadedFile($fileguid);
	if(!$mvcfile)
		continue;

	//process the file here , move to some where
	//rename(...)	

	if($count>0)
		echo(",");
	echo("{");
	echo("FileGuid:'");echo($mvcfile->FileGuid);echo("'");
	echo(",");
	echo("FileSize:'");echo($mvcfile->FileSize);echo("'");
	echo(",");
	echo("FileName:'");echo($mvcfile->FileName);echo("'");
	echo("}");
	$count++;
}
echo("]");
}


//USER CODE:
$rand = substr(md5(microtime()),rand(0,26),10);
$targetfilepath= 'savefiles/' . $rand->rand . $mvcfile->FileName;
if( is_file ($targetfilepath) )
unlink($targetfilepath);
$mvcfile->MoveTo( $targetfilepath );


exit(200);

?>
