Dynamic Signatures

[TimRogers]

How would I make a signature that allows users to put a piece of text into my signature? I know you can use PHP, but I don't have the slightest clue about PHP

(Apart from Cutenews stuff)

Could someone make me a saple signature, very plain, and show me how to allow users to imput text into it thru my website?

Yo Sphinx Myth please check your PM.

I have sent a new dynamic sig!

[Sir Topham Hatt]

Hmm, so which one is the best - the Cache version or the normal one?

Lol, here we go again though - start afresh :)

Okay, it's all good so far :D

BUT, it seems that its behind one. Take a look at:

http://www.wizzyworld.com/externals/sig/

Choose a message, but then when it shows you the message that is current, its the old one.

Although going to: and you can see it actually does change it. Any idea's? this isnt a major bad thing as i could make the "New Message Entered Successfully" page just a simple "Thanks - refresh original page to display the current one" OR even totally redesign it, lol.

Thanks again, Sphinx Myth!!

Ok, here is a new dynamic sig idea!

SigAtlas

I can't take much credit for it, since it's just a butchered version of IP-Atlas.

It will build up a picture of where people are from as they view the sig using their IP and lon/lat info from NetGeo to place a red dot on a map of the earth.

The "Cache" version seems to be the best for you because you don't write any dynamic data as date, IP, weather on your Sig.

Messages aren't dynamic because the sig is created/rendered and saved each time an user posts one of them.

[HeadKaze]: INCREDIBLE! :D

lol, okay, I am leaving it - its working okay.

Question though - how do I remove that white box around the selection thing? Or just make it invisible?

That is the only thing i need to know how to do. I have a feeling it's the "fieldset".

Thanks for ALL the help i have recieved on this :D

Yes, it's "FIELDSET" and "LEGEND".

After you've changed it, how come on the next page it shows the old image still and not the one that it's been changed to?

Try using refresh on your browser.

[Sir Topham Hatt]

It says that the page cant be refreshed but it can be sent again - that box in the middle :/

lol, Pete

Your sig was well updated, but your browser doesn't display the good picture.

As HeadKaze said, refresh your browser. But it doesn't work sometimes because of your browser cache (your browser thinks it's the same picture, so it displays the one it has in its cache).

To override this behaviour, try this little trick (sig_form.php):

<img src="<?=DSIG_SAVED_SIG.'?'.rand( );?>" />

A random parameter suffix is added to the picture URL, but it does nothing (because a picture isn't a script :shifty: ). Browsers will think it's a new picture, will refresh their caches and will display the new picture.

Okay, i'll try it :D

[Sir Topham Hatt]

It works it works!!

Thank you soooo much!!

[joasjdoajsd]

Well...I think I have managed to put together something that is 100% secure. People cannot change the message on your sig by copying the form code to another page on their site and submitting it.

Just use sessions!!!

Removed my sig thanks to some kid who kept writing f**k over and over again. I guess totally dynamic sigs are a bad idea. I'm thinking the "select a quote" option to be a better idea now.

But how to I do it? OCR? hehe no, I don't think so. IP Ban? Maybe, but anyway, I'm bored with the idea of dynamic sigs now anyway. Think I might just have something simple, or a random quote if I'm feeling special.

I could go on about "oh why is the world full of idiots", but really, it's not going to achieve anything except get the idiot more excited about his actions. I really don't care, and I don't know why I'm bothering to write this. I guess it's just a warning to all the other guys using one. It *will* be abused, this place is full of kids. Sad but true. Actually it's not really sad at all, it's a lesson to never expect people to do the right thing. Always write secure code with ways to prevent abuse.

Just use sessions to make sure only one page can change the image. Worked for me.

Any chance you could elaborate on what exactly using a sessions is, and how they work to prevent abuse? Perhaps provide a code example.

Edit: ok, I think I get what you mean, but how does restricting the changing of a sig by one web page prevent the user from writing rude and insulting comments whether that be a text based sig (by using very easy methods to avoid a swearing filter) or by a drawing sig such as SigScribble where identifying such words is practically impossible, even using the most advanced OCR technology.

I doubt it would even be very common for people to POST to the sig from another page. What is the point of that, and how different is it to POSTing from the official page?

I think the only valid method worth bothering with is IP banning.

Or maybe by validating every submitted message/drawing...but very boring...

That is exactly what it prevents users from doing.

Put this in the page that has the form on it (which in this case would be a drop down list)

<?php
session_start();
$_SESSION['Key'] = "Some Big Unknown Key....blablablalba";
?>

and put this on the page that updates your data file

<?php
session_start();
if ($_SESSION['Key'] == "Same as they key you defined in the first file") {
//Your Code Here
$_SESSION['Key'] = "NONE";
}
else
Echo ("Thanks for trying to hack my sig.  Go get a life.");
?>

The user will see the Thanks for trying to hack my sig message if they try to POST the data form another page.

Hope that helps ;)

I have made two new sigs :)

And

Click on me to change what Bill Clinton says!!! :)

Enjoy, pre :)

I had problems with people use rude/insulting words on my sig so I have added a word filter to it, any words that maybe seen as insulting/rude are filtered with * and new words can be added to list via an admin area. But on top of this I also added in ip ban so if i find someone continusly trying to do this on my sig i just simply type in the ip and ban it :)

[headkaze]

How about an auto-ban when someone uses a word from the filter list, that way you may actually prevent some abuse as well.

Hello,

I was wondering if there was a way to use a background image that I already have.

I made a basic image in Photoshop and I want to use it as the background for my dynamic signature.

I know that this is possible, but I do not know how to do it.

I know PHP, but I am not very familiar with the GD image tools. :ermm:

Clunt

[Clinteger]

There's no edit button... :no:

I spelled my name wrong! *Clint*

And I figured it out!

I use "imagecreatefrompng(filename.ext);"

And my host didn't have gd2 installed...
