Call to PHP in signature

[cruocitae]

I have a PHP script which detects the visitors' ip, and creates a [email]root@you.rip.adr.ess[/url] image using the gd library.I've seen that script used on other forums (in siggies), and I'd like to add it here too. br

PNG image [I think other image types work too, but PNG springs to mind].
You have to generate the PNG using PHP then destroy the image when done.

You need a folder on your webserver, and you need to put a .htaccess file in this folder with the following code:

AddType application/x-httpd-php .png

You need to put an image in this folder called sigback.png (called in php file).


Then, this should be saved as sig.png:

<?php

header("Content-type: imageNG");

$text2 = "Your IP is: '.$_SERVER['REMOTE_ADDR'].'.";

$image = imagecreatefrompng("sigback.png");
/* Hex text colour */
$colour = imagecolorallocate($image, 255, 255, 255);

/* X and Y coordinates for the text on your image */

$px=120;
$py=30;

imagestring($image, 2, $px, $py+12, $text2, $colour);

imagepng($image);
imagedestroy($image);
?>

This is untested, so I don't know if it'll work.

You didn't understand me, I already have a script.

<?php
header("Content-type: image/png");
$im = imagecreatefrompng("rootsig.png");
$color = imagecolorallocate($im, 0, 0, 0);
$font = "fonts/verdana.ttf";
$rmpath = $_SERVER['REMOTE_ADDR'];
$curup = "root@".$rmpath;
imageAlphaBlending($im, true);
imageSaveAlpha($im, true);
imagettftext($im, 7.5, 0, 0, 12, $color, $font, $curup);
imagepng($im);
imagedestroy($im);
?>

Well, I admit that yours is a bit more simple.
But how can I insert this png HERE (GC), so every once a user visits the forum he would get this image with his own IP.

Insert the PNG in your signature.

[img]http://www.yoursite.com/images/sig.png[/img]

I don't understand your question now.

[cruocitae]

If I isnert the png, there will only show up a blank white png, and it won't show the user it's ip. Not my ip.

[andrew247]

Um, I dunno.

Did you by any chance put rootsig.png in your signature instead of sig.png?

Does your host support the GD Library?

Hang on, and I'll try and set up mine, and see if I have any difficulties.


EDIT: I have difficulties telling the PNG file to be a PHP file.

I got my PHP file to work. [Here], but when I rename it sig.png, when I try to open the file, it asks what program I want to use to download it. I have a .htaccess file telling all files to open as PHP, regardless of extension, so I'm not sure if it's just my host.
