Dynamic Signatures

March 28, 2005

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?

Hey,

I just went through a whole learning process about this.

The result are my two signature images.

One conjurs up data output by an iTunes plugin, and the other is a random quotes.

I will post the sourece for the latter:

&lt;?php

// tell the user's browser that it is an image
header("Content-type: image/png");

// load the background
$image = imagecreatefrompng("quote.png");

// define the color black (the colour of the text)
$clr_black = imagecolorallocate($image, 0, 0, 0);
$clr_white = imagecolorallocate($image, 255, 255, 255);

// Now let's add the text

// define the font, x_position
// how much the y_position changes (increments)
$line_number = 1;

//Get a random number
$num = rand(1,3);

//Start the switch function
switch ($num) {
//First Quote
case 1:
$quote = "Nothing strengthens authority so much as silence.";
$author = "Leonardo Da Vinci";
break;
//Second Quote
case 2:
$quote = "My life is one long curve, full of turning points.";
$author = "Pierre Elliott Trudeau";
break;
case 3:
$quote = "It\'s amazing what you can accomplish if you do not care who gets the credit. This is a test";
$author = "Leonardo Da Vinci";
break;
}
//Add text to image (img, size, angle, x,y, colour, .ttf, text)
ImageTTFText($image, 8, 0, 10, 50, $clr_black, "verdanai.TTF", stripslashes($author));
ImageTTFText($image, 9, 0, 10, 15, $clr_black, "verdana.TTF", wordwrap(stripslashes($quote), 80));

// and now... we display the image
imagepng($image);
imagedestroy($image);
?&gt;

If your understanding PHP is average, you should be able to pick this apart, and use what you need.

If you need more detailed instructions on how to use this, reply accordingly and I will post a description of the script.

that is cool

from where did you get that information?

March 29, 2005

I want to do this but allow users to choose what text to appear on the signature on a website?

I have done this using a script from a site:

But I want a version where users can change the text on a page on my host.

March 29, 2005

Try these:

Random Banner:

&lt;script LANGUAGE="Javascript"&gt;&lt;!--

// ***********************************************
// AUTHOR: WWW.CGISCRIPT.NET, LLC
// URL: http://www.cgiscript.net
// Use the script, just leave this message intact.
// Download your FREE CGI/Perl Scripts today!
// ( http://www.cgiscript.net/scripts.htm )
// ***********************************************

function banner() {
};

banner = new banner();
number = 0;

// bannerArray
banner[number++] = "&lt;a href='http://www.url1.com' target='_blank'&gt;&lt;img src='images/banner-1.gif' border='0'&gt;&lt;/a&gt;"
banner[number++] = "&lt;a href='http://www.url2.com' target='_blank'&gt;&lt;img src='images/banner-2.gif' border='0'&gt;&lt;/a&gt;"
banner[number++] = "&lt;a href='http://www.url3.com' target='_blank'&gt;&lt;img src='images/banner-3.gif' border='0'&gt;&lt;/a&gt;"
banner[number++] = "&lt;a href='http://www.url4.com' target='_blank'&gt;&lt;img src='images/banner-4.gif' border='0'&gt;&lt;/a&gt;"
banner[number++] = "&lt;a href='http://www.url5.com' target='_blank'&gt;&lt;img src='images/banner-5.gif' border='0'&gt;&lt;/a&gt;"
// keep adding items here...

increment = Math.floor(Math.random() * number);

document.write(banner[increment]);

//--&gt;&lt;/SCRIPT&gt;

Random Avatar:

&lt;?php
header('Content-type: image/jpeg');

//URL of the folder where the avatar images are
//The avatar images and php file can be in different places
$url = "http://homepage.ntlworld.com/frank.cox/damon/images/avatars/";

//List of filenames you wish to randomize, currently only jpegs are supported
//Note the last filename does not need a comma after it
$avatar = array (
"phpone.jpg",
"phptwo.jpg",
"phpthree.jpg"
);

//Select a random image from the list
$size = (count($avatar) - 1);
if (!isset($id) || ($size &lt; 0) || ($id &gt; $size)) {
$id = rand (0, ($size - 1));
}

//Output the image
$img = imagecreatefromjpeg($url . $avatar[$id]);
imagejpeg($img);
imagedestroy($img);
?&gt;

For that, you might want to try Tim Dorr: http://home.timdorr.com/scripts/sig/

If you get the script for that - see if you can post it here?

Hope they help,

Pete

March 29, 2005

Thanks, but what I am intersted in is a version where users can use a page on my site to change the text on it.

March 29, 2005

As above :p

March 29, 2005

^^^

Yeah, like that exactly

March 29, 2005

Wrote something like that a very long time ago, i'll dig it up and i'll post it here sometime today..

March 29, 2005

wow mooodi you rock, i've been looking for something like this for ages!

March 29, 2005

Thanks so much moodi, I expect me and Trix aren't the only ones wanting this

March 29, 2005

Me wants it to!

March 29, 2005

lv 2 rite in it sz bout ritin!!

March 30, 2005

lv 2 rite in it sz bout ritin!!

i didn't understand any of that o.o;;

March 30, 2005

Wrong topic most likely :sleep: :shifty:

Can't wait for moodi to be back!

March 30, 2005

yeh most probably, mee too! mooodi where are you?! D:

March 30, 2005

Waits...

March 30, 2005

It's pretty easy :-

1. Make a page with a form, a textbox and a button on. Make this script submit to something like action.php

2. In action.php make it check to see if something was entered (also badwords, if you feel so inclined). If everything checks out allright then write the text to a .txt file.

3. In your image script use file_get_contents to get the data from inside the textfile and load it to a variable. Write this variable to the image using imagettftext or whatever you're using.

Done !

March 30, 2005

Yeah, I would do that if i knew how to code it :p

But i dont :D

Waits. . .

(Has anyone asked Tim Dorr if he will release his code?!)

March 30, 2005

Zero1... we can't code.. well atleast not from scratch.. and TheTrainMan, yeh i tried once =/

March 31, 2005

Alright, I'll take a couple mins to fire this one out!

1. We'll be using two files for this. form.html and genimg.php (generate image).

form.html will simply have the form that a user can fill out to have the image display.

genimg.php will then take that information and using it to build the image you want!

Here's the form you can put on your site:

&lt;form action="genimg.php" method="post" name="genimg"&gt;
&lt;input type="text" name="text"&gt;&lt;br&gt;
&lt;input type="submit" value="Make Image!"&gt;
&lt;/form&gt;

And here's GenImg.php

&lt;?php

if(isset($_POST['text'])) {
	//generate image
	header("Content-type: image/png");

	$image = imagecreatefrompng("image.png");

	//Colour Black
	$clr_black = imagecolorallocate($image, 0, 0, 0);

	//Add the text! REMEMBER TO ADJUST the number 90 at the end of this line for the length of your image.
	//Simply keep changing it till it works well for your site. (It makes the text not spill off the image).
	ImageTTFText($image, 9, 0, 5, 14, $clr_black, "arial.TTF", wordwrap(stripslashes($_POST['text']), 90));

	imagepng($image);
	imagedestroy($image);
} else {
	?&gt;
	Sorry, you forgot to fill out the form!&lt;br&gt;
	&lt;form action="genimg.php" method="post" name="genimg"&gt;
	&lt;input type="text" name="text"&gt;&lt;br&gt;
	&lt;input type="submit" value="Make Image!"&gt;
	&lt;/form&gt;
	&lt;?php

}
?&gt;

This is a VERY basic code. I thought making it complicated would just confuse you :p.

You'll also need to put arial.TTF in the same directory as this file (You can find this file in: C:\Windows\Fonts\) and you'll also need an existing image named image.png.

The command:

ImageTTFText($image, 9, 0, 5, 14, $clr_black, "arial.TTF", wordwrap(stripslashes($_POST['text']), 90));

Has to be modified to make the text fit where you want it on your image. you can do this by adjusting the numbers 5 and 14. 5 sets the VERTICAL adjustment (up and down) and 14 adjusts the HORIZONTAL adjustment (LEFT and RIGHT). the number 9 is the font size, and the 0 is the angle.

I'd be glad to answer any questions.

EDIT**

Crud, I just relized you are wanting something a little different... You want people on your site to be able to Adjust YOUR signature image. Never mind this script then, it's not what you're looking for...

Notes:

Don't just copy paste the whole thing because its more than likely that you don't have fonts named trhe way I named them.

Make sure you have comments.dat (or whatever you specified your comments file to be) chomd'd to 777.

This is quite old so it is'nt the neatest work ever, and the pages are NOT what my usual stuff looks like.

The code above isn't the whole thing I cut out as much as possible (whilst keeping it error free) so that the comment thing is as clear as possible.

Pages :

filename.ext?go=list : will show all the comments.

filename.ext?go=change : will bring up the add comment change.

Preview :

This is what the above code should output.

Test: Add Comment and Archives.

Hope this is what you wanted ;) and umm sorry for the delay.. :rofl: ,
