Cookies

@developer_webOct 19.2020

Folks,

Why I get echoed:

Cookie ‘guest_visitor’ is set!
Value is: COOKIE_NAME_VISITOR_IP
**Cookie Value ‘COOKIE_NAME_VISITOR_IP’ is not set!**

Problem is last line of echo.

““ $cookie_name = “guest_visitor”; $cookie_value = “COOKIE_NAME_VISITOR_IP”; setcookie($cookie_name, $cookie_value, time() + (86400 * 30), “/”); // 86400 = 1 day

if(!isset($_COOKIE[$cookie_name])) { echo “Cookie named ‘” . $cookie_name . “‘ is not set!”; } else { echo “Cookie ‘” . $cookie_name . “‘ is set!<br>”; echo “Value is: ” . $_COOKIE[$cookie_name]; }

echo “<br>”;

if(!isset($_COOKIE[$cookie_value])) { echo “Cookie Value ‘” . $cookie_value . “‘ is not set!”; } else { echo “Cookie ‘” . $cookie_value . “‘ is set!<br>”; echo “Value is: ” . $_COOKIE[$cookie_value]; } ““

@NogDogOct 19.2020 — #setcookie() does not set anything in $_COOKIE. It sends the cookie to the client when HTTP headers get sent by the script. Subsequent requests from that client to the same domain will then send that cookie _back_ to the server, at which point the receiving PHP page will have it set within the $_COOKIE array.

Ok. I understand all this but still it doesn't explain why I getting mssg Cookie value not set when I get mssg Cookie is set. Either oth should not set or oth should set. Not one set and the either ain't. That is my point. Or, is it because I testing in LocalHost which got no domain or cos I eing oth serer (localhost) and client ?

@developer_webauthorOct 20.2020 — #Folks,

I set cookie so why I get mssg not set ?


 <?php
 
 setcookie("Guest_Visitor_Details", "", time() - 3600);//RETYPE
 
 if(ISSET($_SESSION['user_id']))
 {
 $user_id = $_SESSION['user_id'];
 $user_type = 'member';
 echo "49.member";
 }
 elseif(ISSET($_COOKIE['Guest_Visitor_Details']))
 {
 $user_id = $_COOKIE['Guest_Visitor_Details'];
 $user_type = 'guest';
 echo "55.guest";
 }
 else
 {
 $ip = fetch_ip();
 
 $cookie_name = 'Guest_Visitor_Details';
 $cookie_value = $ip;
 
 setcookie("$cookie_name","$ip",time()+1*24*60*60); //TEST RESULT: Line: 64. Cookie gets set.
 
 if(!ISSET($_COOKIE[$cookie_name]))
 {
 die("Cookie not set!");//TEST RESULT: Line: 68. Cookie got set at line 64 and so why this line 68 triggers here ?
 }
 else
 {
 echo "$cookie_name is: " . $_COOKIE[$cookie_name]; //TEST RESULT: //LINE: 72: Cookie should echoe here as following but script-flow doesn't trigger this line: "Guest_Visitor_Details is: 127.0.0.1".
 }

@NogDogOct 20.2020 — #Maybe because you are setting the cookie expiration time to an hour ago?

<i>
 </i>setcookie("Guest_Visitor_Details", "", time() - 3600);

..._remembering that $_COOKIE will not be set by the setcookie() function,_ only by the receipt of that cookie on subsequent page requests -- and even then the cookie won't be returned if it is expired.

@developer_webauthorOct 21.2020 — #@NogDog#1624431

No. I deleted cookie with that:


 setcookie("Guest_Visitor_Details", "", time() - 3600);

Then re-started the cookie in the ELSE because here the ELSE should trigger since no $_SESSION or $_COOKIE is set.

The script-flow should by-pass IF (due to lacking SESSION) and by-pass ELSEIF (due to lacking Cookie) and land into the "ELSE". And inside this ELSE, you can see that, I set the cookie and so I should not later on down the script-flow get mssg that "Cookie not set".

Line 64


 setcookie("$cookie_name","$ip",time()+1*24*60*60); //TEST RESULT: Line: 64. Cookie gets set.

And so, down the script flow from this point, I never should get mssg on line 68 that, "cookie not set".


 if(!ISSET($_COOKIE[$cookie_name]))
 {
 die("Cookie not set!");//TEST RESULT: Line: 68. Cookie got set at line 64 and so why this line 68 triggers here ?
 }

Still confused anybody ?

If so, fireup xamp/wamp/lamp and test the code ....


 <?php
 
 setcookie("Guest_Visitor_Details", "", time() - 3600);//RETYPE
 
 if(ISSET($_SESSION['user_id']))
 {
 $user_id = $_SESSION['user_id'];
 $user_type = 'member';
 echo "49.member";
 }
 elseif(ISSET($_COOKIE['Guest_Visitor_Details']))
 {
 $user_id = $_COOKIE['Guest_Visitor_Details'];
 $user_type = 'guest';
 echo "55.guest";
 }
 else
 {
 $ip = fetch_ip();
 
 $cookie_name = 'Guest_Visitor_Details';
 $cookie_value = $ip;
 
 setcookie("$cookie_name","$ip",time()+1*24*60*60); //TEST RESULT: Line: 64. Cookie gets set.
 
 if(!ISSET($_COOKIE[$cookie_name]))
 {
 die("Cookie not set!");//TEST RESULT: Line: 68. Cookie got set at line 64 and so why this line 68 triggers here ?
 }
 else
 {
 echo "$cookie_name is: " . $_COOKIE[$cookie_name]; //TEST RESULT: //LINE: 72: Cookie should echoe here as following but script-flow doesn't trigger this line: "Guest_Visitor_Details is: 127.0.0.1".
 }

Any Ideas NogDog ?

Unfortunately not as far as the server side is concerned. On the client side I use local storage instead of cookies as this is easier to handle and provides more space.

@developer_webauthorOct 22.2020 — #@developer_web#1624515

Mmm.

So, you more of a javascript type man ?
