Need help with creating functions

[Anon]

Hi -

Posted earlier, but still having some probs.

Trying to upload multiple images via my getImage function (see below).

the form contains e.g.
<input type=file name=Image>
<input type=file name=Image2>
then calling
getImage($Image);
getImage($Image2);
does not upload. Here's my function presently. Please yell at me when you find the stupid mistake. But do please explain why this is not working, because I'm fairly new at all this. Many thanks to all who take the time...

function getImage($img) {
global $img, $img_name, $img_type, $img_size;

if (!empty($img_name)) {

	if ($img_type == "image/jpeg" or $img_type == "image/pjpeg" or $img_type == "image/gif") {

		if ("image/gif" == $img_type) {
		$ext = ".gif";
		}
		else {
		$ext = ".jpg";
		}

	$imagepath = $server_path . "/gfx/articles/" . date("Ymd") . "." . time() . $type . $ext;

		if (copy($img, $imagepath)) {
		unlink($img);

			if ($img_name == "ImageUpload") {
			$Image = "/gfx/articles/" . date("Ymd") . "." . time() . $ext;
			}
			elseif ($img_name == "ImageUpload2") {
			$Image2 = "/gfx/articles/" . date("Ymd") . "." . time() . "-2" . $ext;
			}
			elseif ($img_name == "ThumbImageUpload") {
			$ThumbImage = "/gfx/articles/" . date("Ymd") . "." . time() . "-t" . $ext;
			}

		echo("success");
		}
		else {
		echo("failure");
		}

	}
	else {
	echo("Not a GIF or JPEG.");
	}


}

}

some incorrect $vars in the previous post.

function getImage($img) {
global $img, $img_name, $img_type, $img_size;

if (!empty($img_name)) {

	if ($img_type == "image/jpeg" or $img_type == "image/pjpeg" or $img_type == "image/gif") {

		if ("image/gif" == $img_type) {
		$ext = ".gif";
		}
		else {
		$ext = ".jpg";
		}

	$imagepath = $server_path . "/gfx/articles/" . date("Ymd") . "." . time() . $type . $ext;

		if (copy($img, $imagepath)) {
		unlink($img);

			if ($img_name == "Image") {
			$Image = "/gfx/articles/" . date("Ymd") . "." . time() . $ext;
			}
			elseif ($img_name == "Image2") {
			$Image2 = "/gfx/articles/" . date("Ymd") . "." . time() . "-2" . $ext;
			}
			elseif ($img_name == "Image3") {
			$ThumbImage = "/gfx/articles/" . date("Ymd") . "." . time() . "-t" . $ext;
			}

		echo("<tr><td colspan='8' bgcolor='#ccccff'>success</td></tr>");
		}
		else {
		echo("<tr><td colspan='8' bgcolor='#ccccff'>failure</td></tr>");
		}

	}
	else {
	echo("<tr><td colspan='8' bgcolor='#ccccff' align='center'>Not a GIF or JPEG.</td></tr>");
	exit();
	}


}

}

Well what''s the problem, what doesn't it do?

It doesn't upload anything. When the function is called, it seems to ignore it and just move on to the next part of the script.

Problem seems to be that the var is not being picked up. Don't know why.

First did you look at the upload routines in the manual?

Second, if you feel like something is not being picked up, print, print and print again! The easiest way to find out if something is missing is by simply printing the vars that you are using.

Also, use the print_r() function on the $HTTP_POST_VARS to see just what the script is receiving.
