Get browser width?

[sciencebear]

Hi all. I need some help. I need to get the width of a user's browser and then turn it into a php variable. I'm not exactly sure how to do this. Any help?

Are you going to send the width off to php through a form or an ajax request? Because you can't detect the page width before it is loaded.

 

To assume you are doing the latter, you can use the jQuery library to do a single, cross browser read, as outlined here:

 

http://api.jquery.com/width/

 

Like so:

 

$(window).width();   // returns width of browser viewport
$(document).width(); // returns width of HTML document

If you run a Google on "JavaScript browser width" you can find the snippet of codes for this.

Hi again. I was able make a function GetWidth() that returns the variable I need. I can make it show in html by using this code:

 

<script type="text/javascript">document.write(GetWidth())</script>

 

However, I need to use that value in PHP. How can I define that as a PHP variable?

 

Edit: I am only using it to define the width of a div tag (It's not just 100%, GetWidth performs some other operations to the browser width). If there's an easier way to do this without PHP, I could do that as well.

You can do something like:

 

<script type="text/javascript">
     
     document.getElementById('myDiv').style.width=getWidth();

</script>

That worked exactly how I needed it to. Thank you very much!
