[jas168]

Hi i have a problem trying to kill a cookie session below is the codes i create the cookie

 

function GetCartId()

{

// This function will generate an encrypted string and

// will set it as a cookie using set_cookie. This will

// also be used as the cookieId field in the cart table

 

if(isset($_COOKIE["cartId"]))

{

return $_COOKIE["cartId"];

}

else

{

// There is no cookie set. We will set the cookie

// and return the value of the users session ID

 

session_start();

setcookie("cartId", session_id(), time() + ((3600 * 24) * 30));

return session_id();

}

}

<?php

setcookie("cartId", "", time() - ((3600 * 24) * 2));

 

?>

Are you sure your not recalling GetCartId() after you try emptying the cookie

[jas168]

yes i am calling GetCarId() after emptying the cookie. because i need to get whats in the cart.

what is the right way to recall all the items in the cart?

 

please advice thank you

Well that function also sets a cookie if one doesn't exist.

[jas168]

what is the work around to retried the cart?

[jas168]

[jas168]

could you please give me an example of the logic

 

thank you advance

If you unset the Cookie, don't set it again.

[jas168]

what if ineed to need to generate a new cookie after i unset cookie.

is here a way around it?

 

because its a shopping cart i am trying to build when click on empty cart, and when add new item it needs to greats a new cookie id.

<?php
setcookie("cartId", "", time() - 3600);
?>

Should work just fine.

 

even time()-1 should work. (I think)

[jas168]

yes i think this works in a normal situation, but i need to call function GetCartId()

and i need an new cookie id after clear.

but it don't seem o work, i a still getting the old cookie id.

 

thanks
