使用javascript将空白变量发布到移动网站

Question

I want to redirect users to a mobile version of my website.

The redirect works fine, however the php variables are not passing.

I am using the following:

<script>
if ($(window).width() < 480 || $(window).height() < 480) {
var searchproducts = "<?php $_GET['search']?>";
var category = "<?php $_GET['cat']?>";

var page="http://m.website.com/search.php?search="+searchproducts+"&cat="+category;
document.location.href=page;

}
</script>

I have also tried:

<script>
if ($(window).width() < 480 || $(window).height() < 480) {
window.location.replace("http://m.website.com/search.php?search=<?php $_GET['search']?>&cat=<?php $_GET['cat']?>");

}
</script>

Can anyone help?

Thanks

You need to add the echostatement..

var searchproducts = "<?php echo isset($_GET['search']) ? $_GET['search'] : 'Nothing'; ?>";
var category       = "<?php echo isset($_GET['cat']) ? $_GET['cat'] : 'Nothing'; ?>";

Also, use an isset construct as shown.
