Resize width

[isabellek]

Hello,
I know this should be really easy - just a matter of switching some variables, but I'm getting all mixed up. I'd like to resize images by width (not by height as it's set now).

if(isset($_POST['Submit']))

{
	$size = 300; // the thumbnail height

$filedir = 'img_original_main/'; // the directory for the original image
$thumbdir = '../img_resize_main/'; // the directory for the thumbnail image
$prefix = ''; // the prefix to be added to the original name

$maxfile = '2000000';
$mode = '0666';

$userfile_name = $_FILES['image']['name'];
$userfile_tmp = $_FILES['image']['tmp_name'];
$userfile_size = $_FILES['image']['size'];
$userfile_type = $_FILES['image']['type'];

if (isset($_FILES['image']['name'])) 
{
	$prod_img = $filedir.$userfile_name;

	$prod_img_thumb = $thumbdir.$prefix.$userfile_name;
	move_uploaded_file($userfile_tmp, $prod_img);
	chmod ($prod_img, octdec($mode));

	$sizes = getimagesize($prod_img);

	$aspect_ratio = $sizes[1]/$sizes[0]; 

	if ($sizes[1] <= $size)
	{
		$new_width = $sizes[0];
		$new_height = $sizes[1];
	}else{
		$new_height = $size;
		$new_width = abs($new_height/$aspect_ratio);
	}

	$destimg=ImageCreateTrueColor($new_width,$new_height) or die('Problem In Creating image');
	$srcimg=ImageCreateFromJPEG($prod_img) or die('Problem In opening Source Image');
	ImageCopyResampled($destimg,$srcimg,0,0,0,0,$new_width,$new_height,ImageSX($srcimg),ImageSY($srcimg)) or die('Problem In resizing');
	ImageJPEG($destimg,$prod_img_thumb,90) or die('Problem In saving');
	imagedestroy($destimg);
}

I think this is really all you need to do:

On the line where you have been declaring max thumb height, now just declare max thumb width, and that should be it..

$size = 300; // WIDTH
