How to set a cookie for signup page?

Question

I am new to php programming. I designed a signup form for my site. After signup anyone can download some files in that site. Now I am looking for to set cookie for signup page.

<div class="field submit" style="text-align:center;">
  <input type="submit" value="signup"/>
  <?php 
    setcookie("signup",time()+3600, "/");
    if (isset($_COOKIE['signup'])) { 
      print "<p>Hello $_COOKIE[signup]</p>";         
    } else { 
      print "<p>Hello, This is your first visit</p>"; 
    } 
  ?> 
</div>

I am using the code like this but it was showing a warning.

`$_COOKIE[signup]` still needs string encapsulation. `$_COOKIE['signup']` — Ohgodwhy, Apr 04 '14 at 07:00

You passing wrong parameter to setcookies, you missing second parameter value in it.

setcookie("signup","username",time()+3600, "/");

Do you have header redirect script in your code ? I cannot see in the code you psoted in question. Can you post the compete code as if line:33 ? – Rikesh Apr 04 '14 at 08:34
Rikesh I put my code in pastebin see this link http://pastebin.com/Sa0iZBTt Thank you – Sujitha Apr 04 '14 at 12:20
You haven't posted `samplecook.php` where actually you getting this warning. – Rikesh Apr 04 '14 at 12:25
Rikesh i renamed the samplecook.php to signupform.php – Sujitha Apr 04 '14 at 12:56
I got error like this Notice: Undefined index: signup in D:\localserver\htdocs\signup\signupform.php on line 32 Hello, This is your first visit – Sujitha Apr 04 '14 at 12:59
before setcookie line check if $_POST really contains signup var in it. Something like `if(isset($_POST['signup']))`. – Rikesh Apr 04 '14 at 13:13

@Sujitha - you should have setcookie function call before any html output in your file. refer [this](http://stackoverflow.com/questions/2658083/setcookie-cannot-modify-header-information-headers-already-sent). – Rikesh Apr 08 '14 at 06:44
