GD Image resizing and saving thumb

punstc · June 24, 2008

I'm really new at php and trying to figure out some of the image resizing things. but i'm having problems. I'm working with some reference that my lab instructor gave me but trying to combine it with my own code I'm running into problems. It keeps giving me this error

Warning: move_uploaded_file(../gallery_images/large/) [function.move-uploaded-file]: failed to open stream: Is a directory in /home/2008/03/jchamberlain/public_html/wpr/final_project/admin/gallery2.php on line 21

Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move '/tmp/phpl9AFmE' to '../gallery_images/large/' in /home/2008/03/jchamberlain/public_html/wpr/final_project/admin/gallery2.php on line 21

I could really use some help on this heres my code

<?php
$this_file = basename($_SERVER['PHP_SELF']);

if(empty($_POST)){
$status = ' ';	
}
else {
	$desc = $_POST['desc'];
	$destination = '../gallery_images/large/';
	$large = $_FILES['large']['name'];
	$large_tmp = $_FILES['large']['tmp_name'];
	$error_list = array();

	if(empty($large)){
		$error_list[] = 'Image';
	}
	if(empty($desc) OR ($desc == 'Description')){
		$error_list[] = 'Description';
	}
	else {
			if(move_uploaded_file($large_tmp, $destination)){


				$image_path = "../gallery_images/large/$large"; // Gets temorary image name from the server
				$dest_path = "../gallery_images/thumb/"; // Sets path to thumbnail images


				$max_width = 200;
				$max_height = 150;

				$size = GetImageSize($image_path);
				$width = $size[0];
				$height = $size[1];
				$x_ratio = $max_width / $width;
				$y_ratio = $max_height / $height;

				if(($width <= $max_width) && ($height <= $max_height)){
				  $new_width = $width;
				  $new_height = $height;
				}
				elseif(($x_ratio * $height) < $max_height){
				  $new_height = ceil($x_ratio * $height);
				  $new_width = $max_width;
				}
				else{
				  $new_width = ceil($y_ratio * $width);
				  $new_height = $max_height;
				}

				$src = imagecreatefromjpeg($image_path);
				$dst = imagecreatetruecolor($new_width,$new_height);
				imagecopyresized($dst, $src, 0, 0, 0, 0, $new_width,$new_height,$width,$height);
				imagejpeg($dst,"$dest_path"."$large", 90);
				$thumb = "$dest_path"."$large";
				imagedestroy($src);
				imagedestroy($dst);

				$status = "<p>The image \". $image. \" has been uploaded!</p>";


				$sql = "INSERT INTO jchamb_gallery SET large='$large', thumb='$thumb' desc='$desc'";
				$result = mysql_query($sql);

			}

			else{
				$status = "<p>There was an error uploading the image, please try again.</p>";
			}
		}
	}
if(count($error_list) > 0) {
	$status = "<p>You did not provide a(n):</p>\n";
	foreach($error_list as $error){
	    $status .= "\t<p><strong>$error</strong></p>\n";
	}
}	

?>

Make this line:

$destination = '../gallery_images/large/';

Into:

$destination = '../gallery_images/large/$large';

And put it after you create $large.

You must not have GD support or you don't have JPEG support on your server. Do me a favor please. Create a new file and put this in it, then show me the output:

<?php

if (imagetypes() & IMG_JPEG) {

echo "JPEG support enabled.";

}

else {

echo "JPEG support not enabled.";

}

?>

Just like that.

punstc · June 25, 2008

it output this

Fatal error: Call to undefined function imagetypes() in /home/2008/03/jchamberlain/public_html/wpr/final_project/admin/test.php on line 2

I'm testing all this on my schools server which we have to upload our projects to. It should have the GD library installed to because i'm basing the code off a script my lab instructor gave me

thanks for helping I really appreciate this.

DarkWater · June 25, 2008

GD is not installed. Do phpinfo(); and look for GD. =X It's definitely not installed if it's giving you that message though. =X

punstc · June 25, 2008

I'm looking in to how to install the GD library on php.net

but jsut incase I can't install it is there another way to do the resizing?

DarkWater · June 25, 2008

No. And I doubt you'll be able to install it unless you get access to the server.

punstc · June 25, 2008

Well thank you for taking the time to help, i really appreciate it, I guess ill just fake it with css.

.josh · June 25, 2008

well you could always ask your host to install it. frankly I'm kinda surprised they don't have it, but w/e. Failing that, you can specify dims with html tags or w/e.

DarkWater · June 25, 2008

@Crayon Violent: I think he meant literally resizing it as a thumbnail, but whatever. xD

.josh · June 25, 2008

@Crayon Violent: I think he meant literally resizing it as a thumbnail, but whatever. xD

yeah that is what he meant but I was talking about alternatives to gd. I know it doesn't make a physically smaller pic but display-wise, it can be shown as thumbnail sized that way.
