Clear all cookies/set cookie

How can I in an if statement

1. clear all cookies previously set
and then
2. set a cookie

BTW, I know how to do #2.....


Thanks

if(isset($_COOKIE['name'])){
setcookie ("name", "", time() - 3600);
}


This will set the expiry time in the past, making the cookie wipe itself out.

If you check the manual before you post, you'll get your answer alot faster

Thanks, what I am doing is setting a cookie for the preference of style on my site. What is doing is setting a cookie, and I guess its not overwriting it....here's my script

//This is the form action
<?php
$value = $_POST['colors'];
$blue = "Royale Blue";
$teal = "Teal";
$green = "Hunter Green";
$maroon = "Maroon";
$grey = "Grey";

if ($value == $blue){
setcookie("blue",time()+3600);}

elseif ($value == $teal){
setcookie("teal",time()+3600);}

elseif ($value == $green){
setcookie("green",time()+3600);}

elseif ($value == $maroon){
setcookie("maroon",time()+3600);}

elseif ($value == $grey){
setcookie("grey",time()+3600);}

else
{
echo "Nothing isset!";
}

?>

and heres what checks

//Checks for cookie, then echos a style sheet
<?php
if (isset($_COOKIE['blue'])){
echo "<link rel=stylesheet href=styleblue.css type=text/css>";}

elseif (isset($_COOKIE['teal'])){
echo "<link rel=stylesheet href=styleteal.css type=text/css>";}

elseif (isset($_COOKIE['green'])){
echo "<link rel=stylesheet href=stylegreen.css type=text/css>";}

elseif (isset($_COOKIE['maroon'])){
echo "<link rel=stylesheet href=stylemaroon.css type=text/css>";}

elseif (isset($_COOKIE['grey'])){
echo "<link rel=stylesheet href=stylegrey.css type=text/css>";}

else {echo "<link rel=tylesheet href=style.css type=text/css>";}
?>It will work the first or couple of times you select a different color, but then after the first or second time, it wont do it until the cookie times out.....

Thanks

Help anyone?:thumbsup:

Anybody?

Why not save yourself time and only use one cookie instead of 5 or so? Just change the value in the cookie to the colour you want. If the cookie's set, echo the cookie's value into the stylesheet link, if it's not set, load the default style

Could you show me an example, Nightfire?

Thanks a million...you guys are great

// set cookie from a link page.php?styles=blue
$value = $_GET['styles'];

setcookie("stylesheet",$value,time()+3600);

// check for cookie and show correct stylesheet

if(isset($_COOKIE['stylesheet'])){
$link = $_COOKIE['stylesheet'].'css';
}else{
$link = "defaultstyle.css";
}

echo '<link rel="stylesheet" type="text/css" href="'.$link.'" />';

I've seen something before like

if (isset($_COOKIE['name'])){
echo "<link rel=stylesheet href=$style>";

not using the $_GET['method'];

and $style was set in the cookie....how can I do that?

Okay, for some reason it is echoing stylecss instead of style.css....
Here is the code

<?php
if(isset($_COOKIE['stylesheet'])){
$link = $_COOKIE['stylesheet'].'.css';
}else{
$link = "style.css";
}
echo '<link rel=stylesheet type=text/css href='.$link'>';
?>

echo '<link rel=stylesheet type=text/css href='.$link.'>';

You're missing a . after $link

Works wonderful! Thanks so much guys!!
