Limit [SIZE] tag

I was looking around for a hack to limit how large users can make their text size via the vb [SIZE] tag.

I was looking at the preg_replace() function (
http://us4.php.net/manual/en/function.preg-replace.php ).

I'm not sure what to do because the size tag can be done in two different ways making the replace statement more difficult:

PHP Code:


		
			
[SIZE=4]Blah[/SIZE]

[SIZE=+4]Blah[/SIZE]

Size=4
Size=+4

Any help would be appreciated. Size=100 in signatures gets old quick. :(

Thanks!

PHP Code:


		
			
[disable]$message = preg_replace("/\[size=\+(\d+)\](.+)\[\/size\]/siU", "[size=\\1]\\2[/size]", $message);

$message = preg_replace("/\[size=(4|5|6|7|8|9|10|11|12|13)\](.+)\[\/size\]/siU", "[size=3]\\2[/size]", $message);[/disable]

is what I use to limit it to 3. It makes the + useless. I use it in new reply, new thread, and edit post. Where is kind of irrelevant, as long as it is before $message is saved into the db. ;)

Just experiment with positioning. :)

hmmm. I suppose that's a good start but it didn't work completely on my site.

Size=100 still went through (or anything over 13) and some of the other sizes I tried ended up as this character:

Didn't work completely? What's wrong with the code supplied by cirisme?

I just realized that the other day(after a member used 15), so I updated my code to handle it:

PHP Code:


		
			
[disable]$message = preg_replace("/\[size=\+(\d+)\](.+)\[\/size\]/siU", "[size=\\1]\\2[/size]", $message);

$message = preg_replace("/\[size=(4|5|6|7|8|9|\d\d|\d\d\d)\](.+)\[\/size\]/siU", "[size=3]\\2[/size]", $message);[/disable]

When I get time, I plan on updating and testing this: (it should work, but I haven't tested it just yet :surprised: )

PHP Code:


		
			
[disable]$message = preg_replace("/\[size=\+?[4-999]\](.+)\[\/size\]/siU", "[size=3]\\1[/size]", $message);[/disable]

It will go to size 999, but you could make it go higher ;)

Just tested it, and this works well:

PHP Code:


		
			
[disable]$message = preg_replace("/\[size=\+?[4-9]*\](.+)\[\/size\]/siU", "[size=3]\\1[/size]", $message);[/disable]

Enjoy :)

I tried that code as well and had problems.

Try the statement:

PHP Code:


		
			
 I go to some fast food place and get super [size=+4]size 5[/size].

Size 5 gets replaced with .

Make sure you change the \1 to have double slashes(\\1), apparently vb.org's php tags mess up the double slashes.

Ahhh thanks.

My only consideration now would be if someone enters the number 1000000 for the size.

Hehehe.

Nice site btw. I registered there under Ibuprofen. Good reading for sure.

Heh, at first I thought I had this covered, but I just realized I don't. As long as they don't go to 4 they can still abuse it, so they could do 33(or 3333 for example) and be fine :paranoid:

Let's keep this a secret till I can find a fix ;)
