Doubleclick random number generator?

[masm50]

Hi all,

I use Bulletmedia as my ad network, and theys erve ads through DoudleClick DART. So that is my code.

I need to add a random number generator to the add code so it writes a 5 digit number different for ever page view. I need it to write the same number 4 times in the code.

I think you can do this with javascript. I would appreciate any help with it, as I'm a complete newbie to JavaScript.

Cheers

Hi, I think the following code should generate a random 5 digit number. Just add your adnetwork code in the "document.write" part of the code inserting '+RN+' wherever you want the random number inserted. If you code is more than just a image and click URL you can add more document.write lines. HTH

<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
RN = Math.floor(Math.random() * (1 + 99999 - 10000) + 10000);
document.write('<a href="INSERT YOUR CLICK URL HERE?'+RN+'">');
document.write('<img src="INSERT YOUR IMAGE URL HERE?'+RN+'"></a>');
// End -->
</SCRIPT>

Thanks a lot for your help John!

But I'm still stuck on how to implement that random number generator.

Here's the code I have to add to my pages:

<IFRAME SRC="http://ad.doubleclick.net/adi/musicware.bulletmedia/;sz=468x60;ord=19761534551833420?" name="frame1" width="468" height="60" frameborder="no" border="0" MARGINWIDTH="0" MARGINHEIGHT="0" SCROLLING="no">
<SCRIPT language="JavaScript1.1" SRC="http://ad.doubleclick.net/adj/musicware.bulletmedia/;abr=!ie;sz=468x60;ord=19761534551833420?">
</SCRIPT>
<NOSCRIPT>
<A HREF="http://ad.doubleclick.net/jump/musicware.bulletmedia/;abr=!ie;sz=468x60;ord=19761534551833420?"><IMG SRC="http://ad.doubleclick.net/ad/musicware.bulletmedia/;abr=!ie;sz=468x60;ord=19761534551833420?" border=0 height="60" width="468"></A>
</NOSCRIPT>
</IFRAME>

I have to replace every time the number 19761534551833420 with the random generated number that is 5 digits or more.

Thanks in advance

Tim

Ok, you could try the following ...

<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
RN = Math.floor(Math.random() * (1 + 99999 - 10000) + 10000);
document.write('<IFRAME SRC="http://ad.doubleclick.net/adi/musicware.bulletmedia/;sz=468x60;ord='+RN+'?" name=\"frame1\" width=\"468\" height=\"60\" frameborder=\"no\" border=\"0\" MARGINWIDTH=\"0\" MARGINHEIGHT=\"0\" SCROLLING=\"no\">');
document.write('<SCRIPT language=\"JavaScript1.1\" SRC="http://ad.doubleclick.net/adj/musicware.bulletmedia/;abr=!ie;sz=468x60;ord='+RN+'?"></SCRIPT></IFRAME>');
// End -->
</SCRIPT>
<NOSCRIPT> 
<A HREF="http://ad.doubleclick.net/jump/musicware.bulletmedia/;abr=!ie;sz=468x60;ord=12345?"><IMG SRC="http://ad.doubleclick.net/ad/musicware.bulletmedia/;abr=!ie;sz=468x60;ord=12545?" border=0 height="60" width="468"></A> 
</NOSCRIPT>

... IE 3.0b2 and higher should understand the <IFRAME> tags, all other Javascript enabled browsers should output the Javascript code between the IFRAME tags (May also output the 1st IFRAME tag but is should be ignored by the browser) and all others should output the code between the <NOSCRIPT> tags. So long as you are using Javascript to generate the random number I don't think you can add it to the code in the <NOSCRIPT> tags since that is for browsers that don't support Javascript.

For rich media code including Javascript you may want to consider generating the random number on the server side instead of with Javascript. In other words using something like ASP, PHP or SSI. For example, if your server supports PHP, you could add something like the following before the code ...

<?php

srand((double)microtime()*1000000); 
$random = rand(10000,99999);

?>

and then insert the following in your page ...

<IFRAME SRC="http://ad.doubleclick.net/adi/musicware.bulletmedia/;sz=468x60;ord=<?php echo $random; ?>?" name="frame1" width="468" height="60" frameborder="no" border="0" MARGINWIDTH="0" MARGINHEIGHT="0" SCROLLING="no"> 
<SCRIPT language="JavaScript1.1" SRC="http://ad.doubleclick.net/adj/musicware.bulletmedia/;abr=!ie;sz=468x60;ord=<?php echo $random; ?>"></SCRIPT> 
<NOSCRIPT> 
<A HREF="http://ad.doubleclick.net/jump/musicware.bulletmedia/;abr=!ie;sz=468x60;ord=<?php echo $random; ?>?"><IMG SRC="http://ad.doubleclick.net/ad/musicware.bulletmedia/;abr=!ie;sz=468x60;ord=<?php echo $random; ?>?" border=0 height="60" width="468"></A> 
</NOSCRIPT> 
</IFRAME>

If SSI is enabled on your server, you could add the following line where you want your banner on your page ...

<!--#include virtual="/cgi-bin/cacheburst.cgi"-->

and then create a file in your cgi-bin named cacheburst.cgi that contains something like the following ...

#!/usr/bin/perl
 
srand(time ^ ($$+($$<<15)));
my $random = int(rand(100000));
 
print "Content-type: text/html\n\n";
print <<BANNERCODE;
 
<IFRAME SRC="http://ad.doubleclick.net/adi/musicware.bulletmedia/;sz=468x60;ord=$random?" name="frame1" width="468" height="60" frameborder="no" border="0" MARGINWIDTH="0" MARGINHEIGHT="0" SCROLLING="no"> 
<SCRIPT language="JavaScript1.1" SRC="http://ad.doubleclick.net/adj/musicware.bulletmedia/;abr=!ie;sz=468x60;ord=$random?"></SCRIPT> 
<NOSCRIPT> 
<A HREF="http://ad.doubleclick.net/jump/musicware.bulletmedia/;abr=!ie;sz=468x60;ord=$random?"><IMG SRC="http://ad.doubleclick.net/ad/musicware.bulletmedia/;abr=!ie;sz=468x60;ord=$random?" border=0 height="60" width="468"></A> 
</NOSCRIPT> 
</IFRAME>

I hope one of these works for you!

You've been a lot of help,

THANKS!

A small question. Why is a random number required with doubleclick code? Do they ask you to do so? Why?

[masm50]

LastActionHero,

Yes, they asked me to put this random number generator in my code. They said it is to stop caching.

That's all I know I'm afraid,

Cheers

You can also right click-view source on this page, I think these ads on the forum use a jscript random thing.

It's interesting that they didn't provide this themselves, or direct you as to where such code can be found.

Still, at least you have connections in all the right places who are ready and willing to offer their assistance.

Thanks John!
