I have a page, test.php, with the following code:
<html>
<body>
<form>
<script type="text/javascript">
function SendCookies(){
if (window.XMLHttpRequest)/* code for IE7+, Firefox, Chrome, Opera, Safari */
{ xmlhttp=new XMLHttpRequest(); }
else /* code for IE6, IE5 */
{ xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); }
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status == 200)
{
alert('done');
}
}
xmlhttp.open("GET", "/web/DEV/Classes/SetCookie.php?time=" + new Date());
xmlhttp.send();
}
</script>
<input type="text" id="txtInput" name="txtInput"/>
<input type="button" id="btnSubmit" name="btnSubmit" value="Submit" onclick="SendCookies()"/>
<div id="divTest">
<?php
if (isset($_COOKIE["TestCookie"])) {
echo $_COOKIE["TestCookie"];
} else {
echo "__Results__";
}
?>
</div>
</form>
</body>
</html>
I have a page, SetCookie.php, with the following code:
<?php
$var = "THIS IS A TEST";
setcookie("TestCookie", $var, time()+60*60*24*30);
?>
When test.php's button is clicked, i use XMLHttpRequest to call my SetCookie.php page. The page executes, becuase if i add an echo to it, i get that in the xmlhttp response. However, TestCookie does not seem to be getting set.
If in text.php, i do the same command found in SetCookie.php, the cookie is then set accordingly for all browser sessions.
Even after i close / open the browser, the cookie remains unchanged from when i once set it in my test.php page manually.
----EDIT-----
I added:
if(!setcookie("TestCookie", "A", time()+60*60*24*30, "/")) {
echo "FAIL";
}
to the very top of test.php, however when i reload the page, it never shows the updated cookie... because that cookie was already set without the ,"/" parameter, and cannot be modified later, with the ,"/" parameter.
After clearing the cache and working with the suggested code, i cleared my cookies from the browser and used the added parameter for the set method, i was able to manipulate the cookies from all pages!!! thank you so much!!

If you don't add a $path value to setcookie(), it defaults to "the current directory". This means that if you set the cookie from /web/DEV/Classes/SetCookie.php, the cookie gets set to /web/DEV/Classes/, and anything above that path won't see that cookie.
To fix this, add a specific $path to setcookie. If your app runs on the domain root (example.com), use '/'. If it's in a subfolder (example.com/myapp/), use '/myapp/'
setcookie("TestCookie", $var, time()+60*60*24*30, '/');
