Clear Cookies

Hi,

I have added the cookies to my page and this works fine (triggered by a checkbox) as per the demo, however when I uncheck the tickbox not to store the cookies they are still saved?

Any help is appreciated.

This is my code:

<%
if (cStr(cStr(Request.Form("remember"))) <> "") then
myExpire = DateAdd("d", 30, Now())
cookieName = "uname"
Response.Cookies(cookieName) = "" & cStr(cStr(Request.Form("useremail"))) & ""
Response.Cookies(cookieName).Expires = myExpire
Response.Cookies(cookieName).Path = "/"
if ("" <> "") then
Response.Cookies(cookieName).Domain = ""
end if
Response.Cookies(cookieName).Secure = 0
end if
%>
<%
if (cStr(cStr(Request.Form("remember"))) <> "") then
myExpire = DateAdd("d", 30, Now())
cookieName = "pname"
Response.Cookies(cookieName) = "" & cStr(cStr(Request.Form("password"))) & ""
Response.Cookies(cookieName).Expires = myExpire
Response.Cookies(cookieName).Path = "/"
if ("" <> "") then
Response.Cookies(cookieName).Domain = ""
end if
Response.Cookies(cookieName).Secure = 0
end if
%>
<%
if (cStr(cStr(Request.Form("remember"))) <> "") then
myExpire = DateAdd("d", 30, Now())
cookieName = "remember"
Response.Cookies(cookieName) = "1"
Response.Cookies(cookieName).Expires = myExpire
Response.Cookies(cookieName).Path = "/"
if ("" <> "") then
Response.Cookies(cookieName).Domain = ""
end if
Response.Cookies(cookieName).Secure = 0
end if
%>


<form id="form1" name="form1" method="POST" action="<%=MM_LoginAction%>">
<table width="450" border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="56">&nbsp;</td>
<td width="302">
<table width="364" border="0" cellpadding="4" cellspacing="0" class="mytable">
<tr>
<td height="25" colspan="3"><legend class="PageHeader">Reviewer Login</legend></td>
</tr>
<tr>
<td width="118" rowspan="4"><img src="images/admin.png" width="118" height="118" /></td>
<td width="58" height="35">Username</td>
<td width="188"><input name="useremail" type="text" id="useremail" value="<%=cStr(Request.Cookies("uname"))%>" /></td>
</tr>
<tr>
<td height="35">Password</td>
<td><input name="password" type="password" id="password" value="<%=cStr(Request.Cookies("pname"))%>" /></td>
</tr>
<tr>
<td height="35">&nbsp;</td>
<td><input name="remember" type="checkbox" id="remember" value="checkbox" <%If (CStr(cStr(Request.Cookies("remember"))) = CStr("1")) Then Response.Write("checked=""checked""") : Response.Write("")%> />
<label for="remember"></label>
Remember Me</td>
</tr>
<tr>
<td><input type="submit" name="button" id="button" value="Logon" /></td>
<td>&nbsp;</td>
</tr>
</table>
</td>
</tr>
</table>
</form>

you would need to add code to the page to clear the cookies if the remeber button is unchecked:

<%
if (cStr(cStr(Request.Form("remember"))) = "" && cStr(cStr(Request.Form("button"))) <> "") then
myExpire = DateTime.Now.AddDays(-1D)
cookieName = "uname"
Response.Cookies(cookieName) = "" & cStr(cStr(Request.Form("useremail"))) & ""
Response.Cookies(cookieName).Expires = myExpire
Response.Cookies(cookieName).Path = "/"
if ("" <> "") then
Response.Cookies(cookieName).Domain = ""
end if
Response.Cookies(cookieName).Secure = 0
end if
%>
<%
if (cStr(cStr(Request.Form("remember"))) = "" && cStr(cStr(Request.Form("button"))) <> "") then
myExpire = DateTime.Now.AddDays(-1D)
cookieName = "pname"
Response.Cookies(cookieName) = "" & cStr(cStr(Request.Form("password"))) & ""
Response.Cookies(cookieName).Expires = myExpire
Response.Cookies(cookieName).Path = "/"
if ("" <> "") then
Response.Cookies(cookieName).Domain = ""
end if
Response.Cookies(cookieName).Secure = 0
end if
%>
<%
if (cStr(cStr(Request.Form("remember"))) = "" && cStr(cStr(Request.Form("button"))) <> "") then
myExpire = DateTime.Now.AddDays(-1D)
cookieName = "remember"
Response.Cookies(cookieName) = "1"
Response.Cookies(cookieName).Expires = myExpire
Response.Cookies(cookieName).Path = "/"
if ("" <> "") then
Response.Cookies(cookieName).Domain = ""
end if
Response.Cookies(cookieName).Secure = 0
end if
%>

Thanks Jason, I thought the extension would do both parts save/delete cookies as required.
but can see how this works now from your code.

Hi,
I have bought the cookie ext but I haven't used it yet.
Now with the new EU law, can you please let me know/send me the code which I can put on a form to give the option to users to store or delete cookies?
e.g. Message: 'This page contain cookies. Do you accept cookies | Yes | No |'
if they tick the Yes option, they can continue and if they select No the cookies will be removed. I use PHP.
thanks

add the radio group and submit button. set the checked value for yes button to 1 and leave the checked value for the no button blank


add a set cookie behavior for each cookie you may have set, for the trigger select the radio group, and set the expiration date to a date in the past. Using a data in the past will delete the cookie

Hi Jason. Can you please provide php code on hoe to clear a cookie when the remember me checkbox is not selected?

This doesn't seem to work:

<?php
if ((isset($_POST["LogIn_submit"])&&(isset($_POST["Log_In_group_3_Remember_my_information"])) && $_POST["Log_In_group_3_Remember_my_information"] == "")) {
setcookie("RememberMeUN", "".((isset($_POST["Log_In_group_Username"]))?$_POST["Log_In_group_Username"]:"") ."", time()+(60*60*24*-1), "/", "", 0);
}
?>

try:

<?php

if (isset($_POST["LogIn_submit"]) && !isset($_POST["Log_In_group_3_Remember_my_information"])) {

setcookie("RememberMeUN", "", time()+(60*60*24*-1), "/", "", 0);

}

?>

Thanks Ray, I'll give it a try.
