I have two things working and want to combine them


firstly a text only on/off switcher which I am going to use to import the stylesheets


$text_only = isset($_GET['text_only']) ? $_GET['text_only'] : 1;

 if ($text_only==1) {
 ?>
<a href="<?php echo $_SERVER['PHP_SELF'];?>?text_only=0">off</a>
// import css here
<?
}
else {
?>
<a href="<?php echo $_SERVER['PHP_SELF'];?>?text_only=1">on</a></span>
// import css here
<?
}
?>


secondly the text size links


<a href="<? $_SERVER['PHP_SELF'];  ?>?text_size=medium" class="size1" id="one">A</a>
<a href="<? $_SERVER['PHP_SELF']; ?>?text_size=larger" class="size2" id="two">A</a>
<a href="<? $_SERVER['PHP_SELF']; ?>?text_size=largest" class="size3" id="three">A</a>


<?
$text_size = isset( $_REQUEST['text_size'] ) ? $_REQUEST['text_size'] : '';

switch ($text_size) {
case "medium":
?>
<link href="css/medium.css" rel="stylesheet" type="text/css" />
<?
break;
case "larger":
?>
<link href="css/larger.css" rel="stylesheet" type="text/css" />
<?
break;
case "largest":
?>
<link href="css/largest.css" rel="stylesheet" type="text/css" />
<?
break;
}
?>

these work great independently but when I use one the other switches off. any ideas how I can combine them?

The key is to pass both values in the URL.  To do that you just append your parameters with a "&":

http://www.mydomain.com/mypage.php?text_only=0&text_size=largest

To get this to happen, just do something like this:

<a href="<? $_SERVER['PHP_SELF'];  ?>?text_size=medium&text_only=<?php echo $_GET['text_only']; ?>" class="size1" id="one">A</a>

This is assuming that they first went to the page and selected text-only, and then when the page reloaded they can then select which size of text they want.  You will need to incorporate this code with some condition checking to see if $_GET['text_only'] is set, etc...

it needs to remember what values are set and then keep them from page to page. I suspect a cookie or session is required and also a way of combining the values.


my css for the divs are simple they just have stuff like

div {

font-size:120%

}



for the text only I am just shutting off all css except the font-size ones.

OK,

One way to do it is through sessions, yes.  Another way is just to keep passing it from page to page.  Sessions is probably the better idea, though.

If you want to use sessions you can do something like:

# Start your session
session_start();

# Check if a new value is passed in
$_SESSION['text_only'] = isset($_GET['text_only']) ? $_GET['text_only'] : 1;

# Now do your css stuff based on what the $_SESSION['text_only'] value is set at
...

Then you do the same kind of thing on the text_size.  Basically, as long as the person has their browser open the $_SESSION values will hold, until you change them of course.

Take a look at http://us2.php.net/manual/en/ref.session.php for more info on sessions.

As for cookies, you could probably use them, but from what I understand they are more for keeping their choices from session to session.
