If you want to make it make compiant with XHTML strict and still wanted to give it the IFRAME look you could have them use the CSS
overflow property.
Code:
.myContent {
overflow: auto;
width: 200px;
height: 300px;
}
Then the HTML to be included on the other site's would be:
if they can use PHP:
Code:
<div class="myContent">
<?php include("http://yoursite.com/youfile.php"); ?>
</div>
Avoiding the PHP only issue
Code:
<div class="myContent">
<script type="text/javascript" src="http://yoursite.com/yourscript.js"></script>
</div>
This javascript would have to output the content of the inner frame but it would not execute as PHP. This may not help at all... but I thought the alternative to IFRAME (which is not compliant) was pertanent.[/code]
