File Upload Problem

[mrcniceguy]

have a script which i found online,through google for uploading and resizing photos when they are uploaded.
It works well,the only problem is that there are some images when i upload them they are not detected as a file,but others are uploaded well.
for example image of this properties is not detected.
(Dimension:3264*2448
camera model,DSC-W150
type:JPEG Image.
size:2,70 MB.
)
below is the script:

<?php
$user=$_SESSION['user'];

if(isset($_POST['submit']))
	{
	include"config.php";
		
		
		
		//make sure this directory is writable!
		$path_thumbs ='C:/wamp/www/website/thumb/';
		
		//the new width of the resized image, in pixels.
		$img_thumb_width = 120; // 

		$extlimit = "yes"; //Limit allowed extensions? (no for all extensions allowed)
		//List of allowed extensions if extlimit = yes
		$limitedext = array(".gif",".jpg",".png",".JPG",".JPEG",".jpeg",".bmp");
		
		//the image -> variables
	    $file_type = $_FILES['vImage']['type'];
        $file_name = $_FILES['vImage']['name'];
        $file_size = $_FILES['vImage']['size'];
        $file_tmp = $_FILES['vImage']['tmp_name'];

        //check if you have selected a file.
        if(!is_uploaded_file($file_tmp)){
           echo "Error: Please select a file to upload!. <br><a href=profilephoto.php>back</a>";
           exit(); //exit the script and don't process the rest of it!
        }
       //check the file's extension
       $ext = strrchr($file_name,'.');
       $ext = strtolower($ext);
       //uh-oh! the file extension is not allowed!
       if (($extlimit == "yes") && (!in_array($ext,$limitedext))) {
          echo "Wrong file extension.  <br>--<a href=profilephoto.php>back</a>";
          exit();
       }
       //so, whats the file's extension?
       $getExt = explode ('.', $file_name);
       $file_ext = $getExt[count($getExt)-1];

       //create a random file name
       $rand_name = md5(time());
       $rand_name= rand(0,999999999);
       //the new width variable
       $ThumbWidth = $img_thumb_width;

	   //////////////////////////

       //keep image type
       if($file_size){
          if($file_type == "image/pjpeg" || $file_type == "image/jpeg"){
               $new_img = imagecreatefromjpeg($file_tmp);
           }elseif($file_type == "image/x-png" || $file_type == "image/png"){

           list($width, $height) = getimagesize($file_tmp);
           //calculate the image ratio

?>

this line here is the one return errors.

//check if you have selected a file.
        if(!is_uploaded_file($file_tmp)){
           echo "Error: Please select a file to upload!. <br><a href=profilephoto.php>back</a>";
           exit(); //exit the script and don't process the rest of it!
        }

Thankx for the link,but still i dont know what to do with the code.

[nickardo]

i found online,through google for uploading and resizing photos when they are uploaded.

Is the script also uploading photo's? and isn't it about serveral extensions?
or file sizes?

[mrcniceguy]

the extension is limited here,which is all image types

$limitedext = array(".gif",".jpg",".png",".JPG",".JPEG",".jpeg",".bmp");

also its not limiting file sizes,thats why i`m suprised.
because it uploads some photos and others is like i mentioned above.

[nickardo]

That is strange indeed is there absolutely no difference between the pictures size extensions etc?

Hi guys, i just wanted to bump this thread, as I'm having the same problem.

I found this resizing function on php.net. and it works fine for jpg and png files, but I'm having problems with uploading and resizing JPG files. the funny thing is, if i rename the image, say DC0001.JPG -> DC0001.jpg, it will be accepted and resize just fine.

Here is the code.

function createimage($name,$filetype,$filename,$new_w,$new_h) {
	
	//$filetype = strtolower($filetype);
	
	if ($filetype=='jpg' || $filetype=='jpeg' || $filetype=='JPG' || $filetype=='JPEG')
		$src_img = imagecreatefromjpeg($name);
	if ($filetype=='png')
		$src_img = imagecreatefrompng($name);
	if($src_img===false) return false;

	$orig_w = imageSX($src_img);
	$orig_h = imageSY($src_img);
	$new_w = ($orig_w > $new_w) ? $new_w : $orig_w;
	$new_h = ($orig_h > $new_h) ? $new_h : $orig_h;
	$dst_img = imagecreatetruecolor($new_w,$new_h);
	if($dst_img===false) return false;
	
	if(imagecopyresampled($dst_img,$src_img,0,0,0,0,$new_w,$new_h,$orig_w,$orig_h)===false) return false;

	if ($filetype=='png'){
		if(imagepng($dst_img,$filename)===false) return false;
	} else {
		if(imagejpeg($dst_img,$filename)===false) return false;	
	}

	imagedestroy($dst_img);
	imagedestroy($src_img);
	
	return true;
}

any ideas about the problem is much appreciated. thanks!

Use var_dump() on you variables to make sure they have the value you expect them to have. For example, checking the value of $filetype would be a good idea.
