Works with Session not with Cookie

DutchBoy01 · October 29, 2009

I'm very much a PHP newbie. I'm currently at the end of Ch 2 of Wrox Begining PHP6 Apache MySQL6 and am working thru the Excersises.

Files: FontColorFamSize1.php & FontColorFamSize2.php

File FontColorFamSize2.php operates error free when lines 3 thru 5 & 26 thru 34 are uncommented and lines 7 thru 11 & 37 thru 45 are commented. Works with sessions not with cookies. Any help much appreciated.

---------------FontColorFamSize1.php--------------

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

First off. Welcome to PHP Freaks :hail_freaks:

Now when posting code please use the code tags (#)

Now on to the code..

SESSIONS (as these work I'm break down WHY they work)

Okay we set the SESSIONS FontFam, FontColor & FontSize to their respective values,

ie the SESSION FontFam = the POSTed FontFam

$_SESSION['FontFam'] = $_POST['FontFam'];
$_SESSION['FontColor'] = $_POST['FontColor'];
$_SESSION['FontSize'] = $_POST['FontSize'];

Now we set $myFontFam to the SESSION FontFam etc

$myFontFam = $_SESSION['FontFam'];
if ($myFontFam == 'SanSerif')  {
    $myFontFamilyNames = "Arial, Helvetica, sans-serif";
} else {
    $myFontFamilyNames = '"Times New Roman", Times, serif';     
}
$myFontColor = $_SESSION['FontColor'];
$myFontSize = $_SESSION['FontSize'];
$myText = $_POST['TextArea'];

OKAY.. now lets take a look at cookies

COOKIES

Okay we set the COOKIES font, size & color to their respective values, (humm not the same as SESSION)

if (isset($_POST['SavePref'])) {
setcookie('font', $_POST['FontFam'], time() + 60);
setcookie('size', $_POST['FontSize'], time() + 60);
setcookie('color', $_POST['FontColor'], time () + 60);
}

Now we set $myFontFam to the COOKIE FontFam etc .. wait one second.. has COOKIE FontFam been set ?

$myFontFam = $_COOKIE['FontFam'];
if ($myFontFam == 'SanSerif')  {
    $myFontFamilyNames = "Arial, Helvetica, sans-serif";
} else {
    $myFontFamilyNames = '"Times New Roman", Times, serif';     
}
$myFontColor = $_COOKIE['FontColor'];
$myFontSize = $_COOKIE['FontSize'];
$myText = $_POST['TextArea'];

So we can fix it by either setting

$myFontFam = $_COOKIE['font'];

OR (PREFERRED)

Setting $_COOKIE['FontFam'] instead of setting $_COOKIE['font']

I hope that helps
