Question

How can you use jQuery to include/require a different php file if window height > 1000?

if window height > 1000

    <?php require('a.php'); ?>

else

    <?php require('b.php'); ?>

Answer 1

You can detect the width and height in javascript and then redirect the page to your actual page.

location.href="myRealPage.php?height="+clientheight;

Then you can use these variables on the server to decide which page to load.

if($_GET["height"]>1000)
{
   require("a.php")?
}
else
{
   require("b.php")?
}
