passing vars, getting size, and two css sheets

myraleen

Ok.
Im not brand new to PHP, but I'm feeling it today.

I have a web site. I am using some simple php at the moment, and later on will develop the site further.

Right now, I have say four pages, each including the header and footer of the page, two css pages, one for 800x600 and one for 1024 browsers.

Now, I have a function, on the index.php (home page) that uses a function to check browser and resolution size of the user's page.
It uses a getsize.htm file... and sends the information back to the home page.

This is working great, and I have gotten the table_width variable and the $css_page variable to send the user to the appropriate file attachements to view appropriately.

But...

When the user then clicks on a button, to take them to another page, say "order" the variables I have collected don't pass, and the tables and css page don't attach.

Help!!!!!???!!!!! please?

the getsize.htm page:

<HTML>
<HEAD></HEAD>
<BODY onload="document.infoform.submit();">
<FORM NAME="infoform" ACTION="home.php" METHOD=POST>
<INPUT TYPE=HIDDEN NAME=getsize VALUE=true>


<script language="JavaScript">
<!--
document.write('<INPUT TYPE=HIDDEN NAME=maxwidth VALUE=\"' + screen.width + '\">');
document.write('<INPUT TYPE=HIDDEN NAME=maxheight VALUE=\"' + screen.height + '\">');
//-->
</script>

</FORM>
</BODY>
</HTML>

the home page (or index but i've named it home.php):

<?php
if(!$_POST["getsize"])header("Location: getsize.htm");
$client_maxwidth = $_POST["maxwidth"];
$client_maxheight = $_POST["maxheight"];


echo "maxwidth: $maxwidth<br>";
echo "maxheight: $maxheight<br>";
// use these in the rest of your code.
if ($maxwidth > 1000) {
	$table_width = "1000";
}
if ($maxwidth < 1000) {
	$table_width = "760";
}
echo "table_width: $table_width<br>";
if ($table_width == 1000 ) {
	$css_page = "tayhawk.css";
} 
elseif ($table_width != 1000) {
	$css_page = "tayhawk2.css";
}
echo "Css Page: $css_page<br>";

echo $_SERVER['HTTP_USER_AGENT'] . "<hr />\n";

$browser = get_browser();

foreach ($browser as $name => $value) {
    print "<b>$name</b> $value <br />\n";
}
global $maxwidth;
global $maxheight;
global $table_width;
global $css_page;

include "header.inc";

phpinfo();
?>
<html>
<head>
<LINK REL=StyleSheet HREF="<?=$css_page?>" TYPE="text/css">
<title>Page Title</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body>
<form name="formInfo" method="post">
	<table width="<?=$table_width?>" cellpadding="2" cellspacing ="2">
~body info~
	</table>
</form>
</body>
</html>
<?php
include "footer.inc";
?>

And the button taken from header.inc:

		<td width="15%">	
			<button class="headerButton" onClick="window.location.href='order.php'">ORDER</button>	
		</td>

And... the css page is called tayhawk2.css or tayhawk.css

any help or pointers would be great, i'm totally lost it seems.

When you execute the following line of JavaScript:
onClick="window.location.href='order.php'
You aren’t passing any variables to order.php in the url and you aren’t setting any session variables.

You need to do one or the other so that the variables such as $css_page will be available. For example: onClick="window.location.href='order.php?css_page=<? echo $css_page ?>'

also instead of:

<?=$css_page?>

use

<?php echo($css_page); ?>

(i think you have a few more of those in your script)

dagon

also instead of:

PHP:

<?=$css_page?>

use

PHP:

<?php echo($css_page); ?>

Why? I alwyas use the top one (less typing) I thought they were identicle

Ok I've added this to the buttons:

<button class="headerButton" onClick="window.location.href='quality.php?css_page=<? echo ($css_page) ?>?table_width=<? echo ($table_width) ?>'">QUALITY</button>

Now, I too am confused as to why it's now syntax<? echo ($var); ?>

But more importantly, it doesn't seem to work!!

I get it ok on the initial 'home' page. And when I click a button It shows the css page and table width in the URL. But it's not passing that info into the page, rather it's defaulting to say 760 table width when it should be at at least 1000.

ugh
