[RESOLVED] resize and copy image twice on post

[Arc]

Hey guys. I am trying this and don't know if it's possible, I can't get it to work.

I need to post an image and then resize and copy it twice....creating a thumbnail and full image out of one image.

Is that possible?

If so, i will post my code.

Of course it is! All of what you talked about doing can be done using the GD library along with a couple of file handling functions native to PHP.

Cool man, that's great news. I was just looking at Yahoo image upload deal and see that they can do it as well.

Ok, here's my code. I can upload an image and resize it and copy it no problem, but my errors are coming when I try to resize and copy the image twice.

Here is the function I use to resize and copy the image.

// Upload and resize photo --------- 
     function jpgResizeUpload($source, $dsrdWidth, $dsrdHeight, $uploadDir, $dsrdImgName, $quality = 70){ 

		/* Check for the image's exisitance */  
    if (!file_exists($source)){  

    }else{  
        list($imageW, $imageH, $type, $attrib) = getimagesize($source); // get variables for image width and height 

        $size = getimagesize($source); // Get the image dimensions and mime type 


        // check image size to make sure it's under desired width x desired height 

        if((($imageW > $dsrdWidth) || ($imageH > $dsrdHeight)) && ($type == "2")) {     // image width or height is greater than what you want 

           if($imageH > $imageW) { 
              $ratio = ($imageH/$imageW); 

              $newH = $dsrdHeight; 
              $newW = ($newH/$ratio);  
           }//end if 

           if($imageW > $imageH) { 
              $ratio = ($imageW / $imageH); 

              $newW = $dsrdWidth;  
              $newH = ($newW/$ratio); 
           }//end if 

           if($imageW == $imageH) { 
              $ratio = "1"; 

              $newW = $dsrdHeight; 
              $newH = $dsrdHeight; 
           }//end if 

        $resize = imagecreatetruecolor($newW, $newH); // Create a blank image 


            switch ($size['mime']){  
                case 'image/jpeg':  
                $im = imagecreatefromjpeg($source);  
                imagecopyresampled($resize, $im, 0, 0, 0, 0, $newW, $newH, $size[0], $size[1]); // Resample the original JPEG 
                $newFileName1 = "$uploadDir/$dsrdImgName";  
                imagejpeg($resize, $newFileName1, $quality);  
                break;  

                case 'image/png':  
                $im = imagecreatefrompng($source);  
                imagecopyresampled($resize, $im, 0, 0, 0, 0, $newW, $newH, $size[0], $size[1]); // Resample the original PNG 
                imagepng($resize, '', $quality); // Output the new PNG 
                break;  
            }//end switch  

            imagedestroy($im);  


   }else{ //image wasn't too big (or was format other than jpeg)... upload as normal 

       copy($source, "$uploadDir/$dsrdImgName"); 
	}//end if
   }//end if  
 }//end uploadResize 

And here is how I am trying to use it

foreach($_FILES as $Image){
   $imageTempName = $Image['tmp_name'];
   $imageName = $Image['name'];
   $imageType = $Image['type'];

 if (!empty($imageName)){
  if ($imageType != "image/pjpeg" AND $imageType != "image/jpeg"){
  $se->errorMessage("error.php","Image must be in .jpg format.","addbefore2.php");
  exit();
  }//end if

 }//end if

   $time = time();
   //resize, rename and copy Full Image

   $fullPath = "/home/httpd/vhosts/collisionsite.com/httpdocs/webadmin/accountimages/$accountID";
	$photo->jpgResizeUpload($imageTempName, "800","600", $fullPath, $time.".jpg");
	$time+=1;
	// Error is coming on this line when I try to fool with the image again $thumbphoto->jpgResizeUpload($imageTempName, "200","600", $fullPath, $time.".jpg");

   if($imageTempName) unlink ($imageTempName);
   if($imageName == NULL){
	$imageNameArray[]="";
   }else{
     $imageNameArray[]=$time;
	}//end if
sleep(1);
}//end for

If you can help me out I appreciate it!

I am getting the error the second time I try to call the jpResizeUpload function. It says someting like, "Call to member function on non existant object". It's like the file no longer exists so I can't use it again.

Any idea what I am doing wrong?

thanks! 🙂

Never mind, I figured it out.
