I remade the page I liked to eariler, to use a better method. Anyway, to change two, you would do something like this:
if (!isset($_GET["file"])) {
$include = "divinclude/default.php";
$include2= "divinclude/default2.php";
}
else {
$include = $_GET["file"];
$include2 = $_GET["file2"];
}
And then you would like to them like this:
<a href="yourpage.php?file=include1.php&file2=include2.php">show new includes</a>
and then just display them in the correct places like this:
include("$include");
and
include("$include2");
