    Hi all,

    I’m trying to modify a PHP / JS script to detect the users screen size and set a variable accordingly but I seem to have hit a snag and nobody on codingforums.com can help me with it :/

    I was hoping that someone here might have some insight
    here’s the thread if it helps:
    http://www.codingforums.com/showthread.php?t=144521&page=2

    and here’s the code:

    <script type="text/javascript">
function nextpage(currlang){
   var url = 'http://www.gryphondor.com?&w=' + screen.width;
   window.location.href = url;

}
</script>

    and here’s the PHP`
    <?php

    /* I pass directly the GET to the variables but you must check
    * first if are safe using some code you want. For example I
    * would restrict $lang to be only ‘fr’ and ‘en’ and w to be a positive non-zero integer
    */

    $w = $_GET[‘w’];
    // and now select the apropriate dir for your resolution
    // first the default, for unexpected values of $w
    $wpdir = ‘wallpapers’;
    if($w == 800){
    $wpdir .= ‘800’;
    }elseif($w == 1024){
    $wpdir .= ‘1024’;
    }elseif($w == 1152){
    $wpdir .= ‘1152’;
    }elseif($w == 1280){
    $wpdir .= ‘1280’;
    }elseif($w == 1600){
    $wpdir .= ‘1600’;
    }
    // here $wpdir will be ‘wallpapers800’ for example

    $wpdir .= ‘/’;

    // constant are really constant, 🙂 so you must define the dirs
    // where you have the wallpapers as constant
    define(‘VL_WALLPAPER_DIR’, $wpdir); `

    and here’s the error i get:
    session_start() [function.session-start]: Cannot send session cache limiter – headers already sent (output started at /mnt/local/home/gryphondor/gryphondor.com/wp-content/themes/vistered-little/wallpaper_functions.php:53) in /mnt/local/home/gryphondor/gryphondor.com/wp-content/themes/vistered-little/wallpaper_functions.php on line 86

    Any idea why / how I can fix this?

    let me try to place the PHP in code brackets again:

    <?php

/* I pass directly the GET to the variables but you must check
* first if are safe using some code you want. For example I
* would restrict $lang to be only 'fr' and 'en' and w to be a positive non-zero integer
*/

$w = $_GET['w'];
// and now select the apropriate dir for your resolution
// first the default, for unexpected values of $w
$wpdir = 'wallpapers';
if($w == 800){
$wpdir .= '800';
}elseif($w == 1024){
$wpdir .= '1024';
}elseif($w == 1152){
$wpdir .= '1152';
}elseif($w == 1280){
$wpdir .= '1280';
}elseif($w == 1600){
$wpdir .= '1600';
}
// here $wpdir will be 'wallpapers800' for example

$wpdir .= '/';

// constant are really constant, :) so you must define the dirs
// where you have the wallpapers as constant
define('VL_WALLPAPER_DIR', $wpdir);

    It looks like your file is sending some kind of output before it tries to start the session, which you can’t do.

    Post the entire file over on http://wordpress.pastebin.ca and post the link back here, so we can take a look at it.
