Help with java script

**fat_lee** · 24th February 2003

Is there any way of changing this java script to HTML so i can use it on my sig?

PHP Code:


 <HEAD>



<SCRIPT LANGUAGE="JavaScript">

<!-- Begin

var rand1 = 0;

var useRand = 0;



images = new Array;

images[1] = new Image();

images[1].src = "http://www.lee404s.dsl.pipex.com/tatu2.jpg";

images[2] = new Image();

images[2].src = "http://www.lee404s.dsl.pipex.com/tatu.jpg";





function swapPic() {

var imgnum = images.length - 1;

do {

var randnum = Math.random();

rand1 = Math.round((imgnum - 1) * randnum) + 1;

} while (rand1 == useRand);

useRand = rand1;

document.randimg.src = images[useRand].src;

}

// End -->

</script>

</HEAD>



<BODY OnLoad="swapPic()">

Here you go

**fat_lee** · 24th February 2003

Thanks guys!!

But is there anyway of doing it so it changes on refresh?

**WTD** · 24th February 2003

Yeah there is using PHP, but your host doesn't provide PHP enabled web space

**fat_lee** · 24th February 2003

If i had a host that did allow PHP could i do it then? even though the forum doesnt allow PHP sigs?

**WTD** · 24th February 2003

Yeah because using PHP and the GD Image library you can create an image, and output it to the browser as an Image, as far as a client is concerned, the php script is an image, as all processing is done server side..

Take a look at this script here

Thats all greek to me mate, never even looked at PHP is it worth looking into as a Hobby language, im not employed in the computer industry nor do i ever want to be, but i like web site building. is it worth bothering?

on a second note you could code that up so i can use it in a sig could you? i know its cheeky but it would look cool

**WTD** · 24th February 2003

lol it is coded up in a script already

Find some PHP enabled webspace, which has GD Image capabilities and I will tell you how to get it working.

i got some php web space and if its just that file i could host it for you ! just gives a shout

**fat_lee** · 25th February 2003

WTD sorry i meant how do i tell it where to put my images etc, i dont understand PHP. it says

$image[$i] = $im; // Add that image filename to the array
$i++; // Increment our counter

does that mean i write it as.

$image[$i] = $im; //www.lee404s.dsl.pipex.com/tatu.jpg
$image[$i] = $im; //www.lee404s.dsl.pipex.com/tatu2jpg
$i++; // Increment our counter

and then paste the lot onto the right kind of web space? or am i barking up the wrong tree?

Ryan thanks for the offer mate i might just take you up on it

Save this as signature.php

PHP Code:


<?php 

Header("Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0"); 

Header("Expires: Thu, 19 Nov 1981 08:52:00 GMT"); 

Header("Pragma: no-cache"); 

Header("Content-Type: image/gif"); 

// Header info, forces no cache and image type of GIF 



$dir = "images" ; // Define the subdirectory to where we store the images.. 



srand((double)microtime()*1000000); // Set a random seed up 

$i = 0; // Set our counter to 0 

$dirHandle = opendir($dir); // Open the images directory 

while(($im = readdir($dirHandle))) // Read in image filenames 

{ 

if($im != ".." && $im != ".") // Don't read in the 2 directories ".." and "." 

{ 

$image[$i] = $im; // Add that image filename to the array 

$i++; // Increment our counter 

} 

} 

closedir($dirHandle); // Close the directory handle 

$n = rand(0,(count($image)-1)); // Create a random number from 0 to the size of the array 



if(!readfile($dir."/".$image[$n])) // Read in a file and output it to the output buffer.. 

readfile($dir."error/error.gif"); // If we can't for some reason use the error.gif file in the error directory 

?>

Put that in a directory with all the images (in gif format) that you want it to open randomly in a subdirectory called "images" on each refresh and bobs your uncle...

Sorry mate you lost me again. when you say put that in the same directory, do you mean on my web space? how would i put it in. on a text file?

http://www.mywebspace.com/folder/tex...ithphponit.txt
www.mywebspace.com/folder/pic1.gif
www.mywebspace.com/folder/pic2.gif

and then i put this file

http://www.mywebspace.com/folder/tex...ithphponit.txt

as my sig in image tags and i will get those two pictures on random refresh?

**WTD** · 25th February 2003

All that code in my post between the lines should go into a file called signature.php

Put that in a folder in some PHP webserver.
In the same folder have a folder called images.
In the images folder put in all the images you want to display. Like image1.gif, image2.gif, image3.gif, image4.gif

Then in your sig put this

[ IMG]http://yourdomain/yourfolder/signature.php[ /IMG]

and it will show you a random image file when you refresh each page.

like I said before, you need PHP enabled webspace, and pipex web space isn't enabled. Hopefully ryan will read this and set this up for you

**fat_lee** · 25th February 2003

It doesnt seem to be working for me mate. ive got that PHP file here

http://members.lycos.co.uk/lee404s/signature.php

and in the same folder there's another folder called images with 2 pictures in mate and all i get is a red x?
