[SOLVED] Image Upload & Resize

[rik72]

http://track9.info/info.php this is my phpinfo

 

I'm using the following code;

 

$fileName = $_FILES["uploadfile"]["name"];
// get the file extension first
$ext = substr(strrchr($fileName, "."), 1);
// make the random file name
do{
$randName = md5(rand() * time());
$pass = "$randName.$ext";
$Check = (file_exists("upimg/$pass") || file_exists("thimg/$pass") || file_exists("avimg/$pass"));
}while( $Check );
$uploadedfile = $_FILES["uploadfile"]["tmp_name"];

list($width,$height)=getimagesize($uploadedfile);

$newwidth1=600;
$newwidth2=180;
$newwidth3=100;
$newheight1=($height/$width)*600;
$newheight2=($height/$width)*180;
$newheight3=($height/$width)*100;

switch($_FILES['uploadfile']['type'])
{
case "image/gif":
	$src = imagecreatefromgif($uploadedfile);//Create from GIF!
	$type = "gif";
break;
case "image/jpg":
case "image/jpeg":
	$src = imagecreatefromjpeg($uploadedfile);//Create from JPEG!
	$type = "jpg";
break;
}
#1
//$src = imagecreatefromjpeg($uploadedfile);//Create from JPEG!
$tmp1=imagecreatetruecolor($newwidth1,$newheight1);
imagecopyresampled($tmp1,$src,0,0,0,0,$newwidth1,$newheight1,$width,$height);
$filename = "upimg/$pass";// . $_FILES["uploadfile"]["name"];
if($type == "gif")
{
imagegif($tmp1,$filename,100);
}elseif($type == "jpg"){
imagejpeg($tmp1,$filename,100);
}
imagedestroy($src);

#2
$tmp2=imagecreatetruecolor($newwidth2,$newheight2);
imagecopyresampled($tmp2,$tmp1,0,0,0,0,$newwidth2,$newheight2,$newwidth1,$newheight1);
$filename = "thimg/$pass";// . $_FILES["uploadfile"]["name"];
if($type == "gif")
{
imagegif($tmp2,$filename,100);
}elseif($type == "jpg"){
imagejpeg($tmp2,$filename,100);
}
imagedestroy($tmp1);

#3
$tmp3=imagecreatetruecolor($newwidth3,$newheight3);
imagecopyresampled($tmp3,$tmp2,0,0,0,0,$newwidth3,$newheight3,$newwidth2,$newheight2);
$filename = "avimg/$pass";// . $_FILES["uploadfile"]["name"];
if($type == "gif")
{
imagegif($tmp3,$filename,100);
}elseif($type == "jpg"){
imagejpeg($tmp3,$filename,100);
}
imagedestroy($tmp2);
imagedestroy($tmp3);

$name = $_FILES["uploadfile"]["name"];
}

 

Can upload fine using firefox, but using internet explorer get this;

 

Warning: imagecopyresampled(): supplied argument is not a valid Image resource in /home/u2/ozaki12/html/track9/newt9/PHP_FILES/uploader.php on line 49

 

Warning: imagedestroy(): supplied argument is not a valid Image resource in /home/u2/ozaki12/html/track9/newt9/PHP_FILES/uploader.php on line 57

 

Any ideas?

<form action="index.php?pageid=31" method="post" enctype="multipart/form-data">
<p><b>Supported Formats: JPG,GIF ONLY!</b></p>

<input type="file" name="uploadfile">

Hummm..

only problem i can see is an extra } at the end of the php script..

 

my test works fine..

<?php
if(isset($_FILES))
{
$fileName = $_FILES["uploadfile"]["name"];
// get the file extension first
$ext = substr(strrchr($fileName, "."), 1);
// make the random file name
do{
$randName = md5(rand() * time());
$pass = "$randName.$ext";
$Check = (file_exists("upimg/$pass") || file_exists("thimg/$pass") || file_exists("avimg/$pass"));
}while( $Check );
$uploadedfile = $_FILES["uploadfile"]["tmp_name"];

list($width,$height)=getimagesize($uploadedfile);

$newwidth1=600;
$newwidth2=180;
$newwidth3=100;
$newheight1=($height/$width)*600;
$newheight2=($height/$width)*180;
$newheight3=($height/$width)*100;

switch($_FILES['uploadfile']['type'])
{
case "image/gif":
	$src = imagecreatefromgif($uploadedfile);//Create from GIF!
	$type = "gif";
break;
case "image/jpg":
case "image/jpeg":
	$src = imagecreatefromjpeg($uploadedfile);//Create from JPEG!
	$type = "jpg";
break;
}
#1
//$src = imagecreatefromjpeg($uploadedfile);//Create from JPEG!
$tmp1=imagecreatetruecolor($newwidth1,$newheight1);
imagecopyresampled($tmp1,$src,0,0,0,0,$newwidth1,$newheight1,$width,$height);
$filename = "upimg/$pass";// . $_FILES["uploadfile"]["name"];
if($type == "gif")
{
imagegif($tmp1,$filename,100);
}elseif($type == "jpg"){
imagejpeg($tmp1,$filename,100);
}
imagedestroy($src);

#2
$tmp2=imagecreatetruecolor($newwidth2,$newheight2);
imagecopyresampled($tmp2,$tmp1,0,0,0,0,$newwidth2,$newheight2,$newwidth1,$newheight1);
$filename = "thimg/$pass";// . $_FILES["uploadfile"]["name"];
if($type == "gif")
{
imagegif($tmp2,$filename,100);
}elseif($type == "jpg"){
imagejpeg($tmp2,$filename,100);
}
imagedestroy($tmp1);

#3
$tmp3=imagecreatetruecolor($newwidth3,$newheight3);
imagecopyresampled($tmp3,$tmp2,0,0,0,0,$newwidth3,$newheight3,$newwidth2,$newheight2);
$filename = "avimg/$pass";// . $_FILES["uploadfile"]["name"];
if($type == "gif")
{
imagegif($tmp3,$filename,100);
}elseif($type == "jpg"){
imagejpeg($tmp3,$filename,100);
}
imagedestroy($tmp2);
imagedestroy($tmp3);

$name = $_FILES["uploadfile"]["name"];
}

?>
<form method="post" enctype="multipart/form-data">

Yeah, thats for an if statement at the top making sure their is an active session, anyone else got any ideas how to fix this?

[MadTechie]

But it works.. ???

 

ooow Okay one thing..

 

try this

switch($_FILES['uploadfile']['type'])
{
case "image/gif":
	$src = imagecreatefromgif($uploadedfile);//Create from GIF!
	$type = "gif";
break;
case "image/jpg":
case "image/pjpeg": //Add this (photoshop jpeg)
case "image/jpeg":
	$src = imagecreatefromjpeg($uploadedfile);//Create from JPEG!
	$type = "jpg";
break;
}

you may want to check to see what IE is providing here:

 

$_FILES['uploadfile']['type']
