Sig image size control

I wrote this hack so i could obviously do what the title says.

When installed it you get an option in vb option of max height and width.

If a user's sig is too big, then when you look at their sig it'll say sorry this image is too large. And if the link doesn't work, then it'll say sorry that image doesn't exist. Thnx.. Don't forget to back up the databases!

[edit]This new one gets rid of the queries.. but, you have to submit your vbulletin options after installing the hack in order for it to work.[/edit]

[edit]Update again, this fixes smooties prob's with it images being set to unlimited[/edit]

So, this hack won't work unless all my users update their bios? It won't work on the fly when the hack is installed?

That would be correct.

[Darren Evans]

Ok... can someone post a query that deletes all sig files so I don't have to go in and manually delete each one?

[Smoothie]

One thing you might try, turn off:
Allow vB IMG code in signatures in the admin cp, submit, then go back and turn it back on.

Nope. That didn't work. Thanks for the reply, though.

update user set signature="";

and yes, it is possible to do it with Swf files, but I haven't written the code for that yet.

[LightBringer]

Herman, has there been any updates on the swf code for this hack?

[Herman]

Ok for SWF! Here it is.. I haven't completely put a lot of thought into this code b/c I was busy today, but it will do the job.

I designed this addition to be completely independant of the IMG sig control hack.. This hack addition will only affect swf's, so if you don't care about IMG and want swfs controled, only install this, however, you can install them both, and it wll control both.

find:

  // check max images
  if ($maximages!=0) {

add ABOVE

    $signature = preg_replace("/(\[)(swf)(=)(['\"]?)([^\"']*)(\\4])(.*)(\[\/swf\])/seiU", "\swf_size_check('\\5','\\7')", $signature);

find at the very end of the file:

?>

add ABOVE:

function swf_size_check($image, $h_w) {


  global $maxsigheight, $maxsigwidth;

  //parse_all img tags

  $image_xy=@getimagesize($image);

  if ($image_xy==NULL)
	{
	return "Image not found";
	}
  else	{
	//ok, here we need to see if the user specified a size(i believe the swf will
	//default to default size if no height width is specified, so lets get the 
	//dimensions of the swf..

	$im_width=$image_xy[0];
	$im_height=$image_xy[1];


	//ok, did the user specify a height? lets see...

	unset($params);
	$params=explode(" ", $h_w);

	foreach($params AS $param)
		{
		if (preg_match("/(height)(=)(['\"]?)([^\"']*)(\\3)/siU", $param))
			{
			$im_height=preg_replace("/(height)(=)(['\"]?)([^\"']*)(\\3)/seiU", "\intval('\\4')", $param);
			}
		if (preg_match("/(width)(=)(['\"]?)([^\"']*)(\\3)/siU", $param))
			{
			$im_width=preg_replace("/(width)(=)(['\"]?)([^\"']*)(\\3)/seiU", "\intval('\\4')", $param);
			}
		}


	if ($im_width > $maxsigwidth)
		{
		return "Sorry, swf size exceeds maximum width of ".$maxsigwidth.".";
		}

	if ($im_height > $maxsigheight)
		{
		return "Sorry, swf size exceeds maximum height of ".$maxsigheight.".";
		}

	}


return "[swf=".$image."]" . $h_w . "[/swf]";
}

Keep in mind, that this is NOT fully tested, but I wrote it b/c of requests.

BTW, why does it parse the BBCODE in the [code] statements? This is very annoying.. In my above post, where the words appear italicized, there should be [i ] and [/i ] ending tags, for those interested.

thx man i installed it

[Thunderpuck]

Excellent! I really needed this. Thanks!

I thought I had this working well, installed it and tested it. I have the max images per post/signature set to 20, I set the max image height to 200 and width to 500 and saved the changes in the options screen. I tested it with a 640x480 image and sure enough, it said I exceeded the width.

I just had a new user register today, and put in a signature of 224x464. The height exceeds my limit in the option yet his signature still show up. So for some reason, it's not checking the height but it checks the width. Can someone verify that if you upload a picture that only exceeds the height limit, that this hack will work? Thanks.

Oh yeah, I just double checked the code from the installation of this hack and everything matches up properly.

Does it work with VB2.0.3 ?

thanks !

[Herman]

rstark, your problem may be that the HTML code is enabled, that will make him able to get a larger signature than usual, so, disable that and it ends.... And it should work with any version of vB.
