using sessions to update font size

[mstringham]

I am looking to allow the user to change the text size when a link is clicked. I am using sessions to track the current style sheet so the font change is displayed and can be changed globally.

As far as I can tell - this should work, but currently does not

<?
session_start();

$css_default = "test_style.css";
$css_one = "test_style1.css";
$css_two = "test_style2.css";


$thestyle = $css_default;

$_SESSION['sess_style'] = $thestyle;

if($changetext){

if($sess_style == $css_default){
$_SESSION['sess_style'] = $css_one;
$thestyle = $sess_style;
}

if($sess_style == $css_one){
$_SESSION['sess_style'] = $css_two;
$thestyle = $sess_style;
}

if($sess_style == $css_two){
$_SESSION['sess_style'] = $css_default;
$thestyle = $sess_style;
}

}


?>

$changetext is the var that gets passed when the user clicks the "change my font size" link.

Any help is appreciated.

I'm not sure exactly how to do it with sessions without sitting down and playing with it. Your other option that I have used in the past is to just use a cookie. That's quite simple and has the same usage as what you are after now; it can be changed globally. Furthermore, a cookie could be set to "remember" the user's font setting for say 72hrs, or more, so if they came back then wouldn't have to reset it.

Just another option/suggestion for you. Something you might want to take a look into.

A session will basically accomplish the same thing for what I'm looking to do here.

My question is more of code syntax - I'm at a loss as to what I'm missing here. from the looks of the conditionals - if should work.

Any help is appreciated.

Thanks

What exactly is the problem? Does it always use your default style sheet? Do you get any errors?

In case anybody cares -

I figured out what I was missing.

if($changetext)
   { 
	 if($_SESSION['sess_style'] == $css_default){ 
	 $_SESSION['sess_style'] = $css_one; 
	 $thestyle = $sess_style; 

  } else {

  if($_SESSION['sess_style'] == $css_one){ 
  $_SESSION['sess_style'] = $css_two; 
  $thestyle = $sess_style; 

  } else {

  if($_SESSION['sess_style'] == $css_two){ 
  $_SESSION['sess_style'] = $css_default; 
  $thestyle = $sess_style; 
}
 }
  }

   } else {

   $thestyle = $css_default; 
   $_SESSION['sess_style'] = $thestyle; 
 } 

Looks like my original logic was right but the way I had it set up , all conditionals were being met each time. I needed to add an else statement after each condition. I also realized a case statement would work well here.

thanks for all input.
