UBB.Developers Forums UBB.threads 7 Development How Do I? removing photos from signatures

my members have started adding photos to their sigs, which i want to stop.
how?
I want them to keep the photos in their profile though, and which they also use as an avatar.
just no photos in sigs!

The easiest way is to not allow them to use the [img] markup tag.

In your config.inc.php file find this:

// Allow the image markup tag.
$config['allowimages']= 1;

and change it to 0 to turn it off.

Also, perhaps your allowing to many characters to be used in the signature. Try lowering the number so it's harder to put an URL to a photo in.



Just some thoughts.

if i remove the img tag though, wont that stop them from posting photos?

That is correct.

You could hack the script to disallow images in signatures.

The code which handles signatures is in changebasic.php. Look for $Signature. This would only affect changes to signatures, not existing signatures.

[]if i remove the img tag though, wont that stop them from posting photos?

---

The most basic solution that was suggested, without hacking would be to decrease the amount of characters allowed in sigs... as an image tag usually takes quite a few characters.

You can adjust that in the config file.

the thing is, i want to keep the sig limit at around the 200 mark, because people were complaining it was too short otherwise.
i want people to post images.
i just dont want images in sigs.
so edit changebasic.php is the way then? what is it I've got to remove? my programming knowledge of php can be written on the back of a stamp!
yep, and after a quick look at changebasic.php, i cant see no reference to images in sigs. i found the sig lines though! lol

I'm not sure I've got the ability either... but if nobody beats me to it.. I'll take a look at it. If i can figure it out I'll post it.

thanks, i would like to get this fixed one way or another!

In your changebasic.php file at around line 185, just above this:

$Signature = $html -> do_markup($Signature);


Add this:

if (eregi("\[img\]",$Signature,$sigimages)) {
$Signature = eregi_replace("\[img\].*\[/img\]|\[{$ubbt_lang['TEXT_IMAGE']}\].*\[\/{$ubbt_lang['TEXT_IMAGE']}\]","",$Signature);
}


This should strip out the img tag.

Ha.

I knew JustDave would know.
I was still hunting for the correct place.

Thanks Dave!

excellent, i'll give it a try 2moro (off out in a minute) and let you know! thanks!

ok, just tried quickly.
I dont have that line anywhere in my changebasic.php file.
what now?

What version are you using?

Post deleted by Dave_L

UBB.threads™ 6.0.3
recently installed it a few days ago

In 6.0.3 changebasic.php, I would add JustDave's code after this:

// --------------------------------
// Get rid of HTML in the signature
$Signature = str_replace("<","<",$Signature);
$Signature = str_replace(">",">",$Signature);
$Signature = str_replace("<br>","<br />",$Signature);

works like a dream!
Cheers guys!
mucho appreciated!

ok, lol
check this out
i *thought* it was solved
but now they are using html in their sigs to get around it!
anyway, i can see how to disable html in posts, but not sigs!
any ideas chaps?

Actually, I didn't think they could use html in their sigs...

What version are you using?

Never mind, seen your post above.. 6.0.3


In that version the code Dave_L showed you above is what keeps html out:

// --------------------------------
// Get rid of HTML in the signature
$Signature = str_replace("<","<",$Signature);
$Signature = str_replace(">",">",$Signature);
$Signature = str_replace("<br>","<br />",$Signature);


Did you remove this?

no, it's still there.
hmmmm, this is most bizarre.

I'm totally confused about how markup and HTML work in signatures now.

6.0.3 was an "emergency" release intended to fix a security bug in 6.0.2, but it also included a few changes from 6.1. I have the 6.0.3 .tar.gz file downloaded for reference, but I'm running 6.1b1 on my server.

There have been a couple of bugs posted regarding signatures. Maybe Rick needs to look at this thread. I'll flag it for his attention.

ok, thanks.

Ok, in 6.0.3 the signature wasn't converted until the post was made. So, the actual markup is stored in the database. That means this won't have any effect on users that already have their signature set. So it would require changing everyone's signatures or hacking showflat/showthreaded as well. I don't have a live copy of 6.0.3 to work on at the moment so not sure right off the top of my head where this would go.

I just found someone on my forums with a photo in his signature, and this was the code for it.
[*image]http://image1ex.villagephotos.com/extern/677958.jpg[*/image] (of course removing stars)
I doublechecked the changebasic.php file, and the hack was still in there.

This is the part with the original code and the hack.

// Get rid of HTML in the signature
$Signature = str_replace("<","<",$Signature);
$Signature = str_replace(">",">",$Signature);
$Signature = str_replace("<br>","<br />",$Signature);
if (eregi("\[img\]",$Signature,$sigimages)) {
$Signature = eregi_replace("\[img\].*\[/img\]|\[{$ubbt_lang['TEXT_IMAGE']}\].*\[\/{$ubbt_lang['TEXT_IMAGE']}\]","",$Signature);
}



that is correct yeah?

The problem is they have already placed this into their signature. The code above will only prevent users that have not added an image to their signature from doing so. You will have to manually edit the user's signature to remove any images that already exist.

ah right. ok! i'll do that now
thanks
(never occured to me)

Is it possible that someone make this compatible for 6.2 ? It's very useful I think

[6.2.1]

changebasic.php

Find:

// -----------------------
// Allow markup in the bio
$Bio = $html -> do_markup($Bio);
$Signature = $html -> do_markup($Signature);

Change it to:

// -----------------------
// Allow markup in the bio
$Bio = $html -> do_markup($Bio);
[:"red"]$allowimages = $config['allowimages']; // save
$config['allowimages'] = 0;[/]
$Signature = $html -> do_markup($Signature);
[:"red"]$config['allowimages'] = $allowimages; // restore[/]

Thanks
It is working great
