Header Error to resize image??

[mcontreira]

Hello everybody,

I created a function called 'imgCreate ()' to resize an image.

I'm trying to use this function to recreate images in two sizes that

I need from a base image received by upload. The question is,

the two images are created from the base image that I keep in a folder 'uploads',

the original image is saved correctly now two other file is created, but it only comes with zero bytes

and the image does not appear, or is not properly created. Another thing also happened

is that the images began to be displayed in binary. I tried to insert the header ("Content-type: image / jpeg)

but still does not work. I've tried several ways to correct but still not had success, if someone can me

better target for correction of these errors will be immensely grateful.

 

Below is the code I'm using.

 

 

Function 'imgCreate()' in file 'funcoes.php':

 

<?php

function imgCreate($imgjpg, $width_target)

{

$img = imagecreatefromjpeg($imgjpg);

 

$width_origin = imagesx($img);

$heigth_origin = imagesy($img);

 

$heigth_new = (int)($heigth_origin * $width_target)/$width_origin;

 

$new = imagecreatetruecolor($width_target,$heigth_new);

 

$criado = imagecopyresampled($new, $img, 0, 0, 0, 0, $width_target, $heigth_new, $width_origin,  $heigth_origin);

 

if($criado){

header("Content-type: image/jpeg");

echo imagejpeg($new, $arquivo, 100);

}

else

return "Not possible create image!";

}

?>

 

Code where I'm trying to use the function:

 

<?php

require 'funcoes.php';

 

$photo = $_FILES["photo"];

 

if(isset($photo))

{

$widthThumb = 117;

$widthImage = 350;

 

$newNamePhoto  = uniqid(time());

 

$newPhoto = "../uploads/".$newNamePhoto;

 

$newNameThumb = $newNameFoto."_thumb.jpg";

$newNameImage = $newNameFoto."_img.jpg";

 

move_uploaded_file($photo['tmp_name'], $newPhoto);

 

$thumb = imgCreate($newFoto, $newPhoto, $widthThumb);

$file  = fopen("../uploads/".$newNameThumb,"wb");

fwrite($file, $thumb, sizeof($thumb));

fclose($file);

 

$image = imgCreate($newFoto, $newPhoto, $widthImage);

$file  = fopen("../uploads/".$newNameImage,"wb");

fwrite($file, $image, sizeof($image));

fclose($file);

}

?>

i am not sure what is wrong in your code, but i might help you by showing the code i always use to do what you want, it works perfectly:

 

$filename = 'photo';
$file = time().'-'.$_FILES['photo']['name'];

if (trim($_FILES[$filename]['tmp_name']) == TRUE)
   {
//photo uploaden
$filename = 'photo';
$source = $_FILES[$filename]['tmp_name'];
$path= 'photos/big/';
$path2= 'photos/small/';
$destination = $path.$file ;
$destination2 = $path2.$file ;
photoupload($filename, $source, $destination, $destination2);

//photo big resizen
$source = $destination;
$maxx= '450';
$maxy= '450';
photoresize($source, $maxx, $maxy);

//photo small resizen
$source = $destination2;
$maxx= '75';
$maxy= '75';
photoresize($source, $maxx, $maxy);
  }


$sql="INSERT INTO photo
(file)
VALUES
('$file')";

if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }

 

and the used functions:

 

 

function photoupload($filename, $source, $destination, $destination2)
{
/*START PHOTOUPLOAD*/


        
// Does the file have the right MIME type?

   if ($_FILES[$filename]['type'] != 'image/pjpeg' AND $_FILES[$filename]['type'] != 'image/jpeg' AND $_FILES[$filename]['type'] != 'image/gif' AND $_FILES[$filename]['type'] != 'image/png' AND $_FILES[$filename]['type'] != 'image/wbmp')
      {
      echo 'the file you want to upload is no photo, please go back to try again';
      exit;
      }

		  
      move_uploaded_file ($source, $destination );
		copy($destination, $destination2);


return 0;	

   

/*END PHOTOUPLOAD*/
}

function photoresize($source, $maxx, $maxy)
{
/*START PHOTORESIZE*/

	// Get current dimensions

    list($width_orig, $height_orig) = getimagesize($source);



       // Check if they are over their limit

       if ( ($width_orig > $maxx) || ( $height_orig > $maxy))

          {

          if ($maxx && ($width_orig < $height_orig)) 
				  {
					$maxx = ($maxy / $height_orig) * $width_orig;
					} 
				else 
					{
					$maxy = ($maxx / $width_orig) * $height_orig;
					}
		   
		   // Resample voorbereiden
		   $image_p = imagecreatetruecolor($maxx, $maxy);
			 $image_type = strtolower( substr($source, strrpos( $source, '.' )) );

			 switch( $image_type )
			   {
				 case '.gif' :  $image = imagecreatefromgif($source);  break;
				 case '.jpg' :  $image = imagecreatefromjpeg($source); break;
				 case '.jpeg':  $image = imagecreatefromjpeg($source); break;
				 case '.png' :  $image = imagecreatefrompng($source);  break;
				 case '.bmp' :  $image = imagecreatefromwbmp($source); break;
				 }
		   // Resample de afbeelding

			 imagecopyresampled($image_p, $image, 0, 0, 0, 0, $maxx, $maxy, $width_orig, $height_orig);

				 // Output
			 switch( $image_type)
			   {
				 case '.gif'  :  imagegif($image_p, $source, 100);  break;
				 case '.jpg'  :  imagejpeg($image_p, $source, 100); break;
				 case '.jpeg' :  imagejpeg($image_p, $source, 100); break;
				 case '.png'  :  imagepng($image_p, $source, 100);  break;
				 case '.bmp'  :  image2wbmp($image_p, $source, 100);break;
				 }
			  
         

        } 
	                                            



return 0;	

    

/*END PHOTORESIZE*/
}		

 

hope it helps!
