单击功能，Window.location

currently, I am trying to set the URL of my website base on what the user click. The website is coding in html and php and this is the code I am trying to use to set the Url. However it seems that windows.location doesn't recognize php code. is there any other way to do this?

    <script>
        $(document).ready(function(){                         
    $("#HELP").click(function(){
   window.location='hotels.php?Category=<?php $cat ?>&Pic=<?php $img ?>';
            });
        });
    </script> 

Try this:

<script>
 $(document).ready(function(){                             

  $("#HELP").click(function(){
    var url = 'hotels.php?Category=<?=$cat?>&Pic=<?=$img?>';
    window.location= url;
     });
  });
</script> 

What change: Echo php veriables in url

But its not a good practice to use php code in client side you can create global veriables in java script.

Or if your requirement is like that than you can also use a hidden value for url in html and than get value in your jQuery code as like that:

<input type="hidden" id="url" value="<?=hotels.php?Category=<?=$cat?>&Pic=<?=$img?>" name="url">

<script> 
$(document).ready(function(){ $("#HELP").click(function(){ 
var url = $('#url').val(); 
window.location= url; 
}); 
}); 
</script> 

You forgot to echo the variables to the output:

window.location='hotels.php?Category=<?php echo $cat ?>&Pic=<?php echo $img ?>';

Variables by themselves don't emit anything to the page. They simply represent a value.
