You'd be handling that in HTML, this only deals with rotating the image and spitting the image out.

FAM99 · Oct 25, 2007, 05:09

Correct me if im wrong but the html output will be,

<img src='mysite.com/rotate.php?i=1'>
<img src='mysite.com/rotate.php?i=2'>
<img src='mysite.com/rotate.php?i=3'>

How does the html know which picture goes to which link without tweaking the code in php, as surely you will have to pass the correct hyperlink with the image?

Thanks

I am getting the error;
Cannot modify header information - headers already sent by (output started at /home/seehereo/public_html/jengasupplementscom/2/rotate.php:9) in /home/seehereo/public_html/jengasupplementscom/2/rotate.php on line 33

example
http://jengasupplements.com.au/2/rotate.php

I figured it out...

I created a rotate.php with just the configuration php (top stuff), then created a index file with just the <img src='http://www.xx.com/rotate.php?i=0'>image #1
and it worked fine

attached is a zip file with pre made files for dummies like me

If you really wanted to do something like that, you would the script to include the <img src> tags, something ti doesn't currently do.

FAM99 · Oct 25, 2007, 05:29

Thats what i have been trying to do with,

$images=array(
"<a href='link1.html'><img src='img1.gif'></a>",
"<a href='link2.html'><img src='img2.gif'></a>",
"<a href='link3.html'><img src='img3.gif'></a>"
);

but i seem unable to output it on the page. Any suggestions where im going wrong?

bluefrogx · Oct 25, 2007, 05:34

Yep, its wrong in the sense that you're trying to adapt the script for something it wasn't meant to do making it overly complex in the process.

Refer to http://www.sitepoint.com/forums/showthread.php?t=510395 , that might fit your requirements more.

FAM99 · Oct 25, 2007, 05:42

That looks just the job, will try it when i get home from work.

Thanks
