Hide div using cookie if page has been already loaded today?

[purplemonster]

Hi,
First, I am absolute javascipt newbie so please threat me like that.. ))

I need the following functionality to my webpage:

Let's say I have a div with some unique ID on my page.
Now, what I need is to show this div on my page only the first time visitor opens a page, and then not show it every next time he/she opens it for next 24h.

So I need to set a cookie that hides div from page if it has already been shown to visitor, for next 24h, so that the content of this div will be shown to each unique visitor only once for a day.

Thanks in advance...

Nikola

I would suggest using PHP for this. That way, if the user is new it can be generated on the spot. If not, then it will not be executed in the html and just be hidden.

Code: Select all


if( isset($_COOKIE['myCookie'])){

//Nothing will happen because the Cookie is set. If not it will go to else:

}else{
echo <div class="myDiv">This content only appears if the Cookie called myCookie is set in the user's browser.</div>
}


Something like that should work before your headers are loaded.

Heeey, thanks for idea!!

Well, I currently have this in my BODY, but it wont work

Code: Select all


<?php
if(isset($_COOKIE['cookiename']))
{ echo "cookie set";
}
else
{ echo
?>
<div id="autoload">
Cookie not set
</div>
<?php
;}
?>


<?php
setcookie("cookiename", "someValue", time()+3600);
?>


And when I view it in browser, and then refresh no matter how many times I get "Cookie not set".

What am I doing wrong?

Your code is off. it should read:

Code: Select all

<?php
if(isset($_COOKIE['cookiename']))
{ echo "cookie set";
}
else
{ echo "<div id=\"autoload\">Cookie not set</div>"
;}

setcookie("cookiename", "someValue", time()+3600);
?>
I apologize my code was wrong in my first reply.
