Hello,

 

I have made this registration script with all th features i wanted except "remembre me" feature, which i want to add to the login page but dont know how.

 

I am using sessions, i know about the time() parameter for cookies but cannot squezze it all in to get what i want, so can someone help me out ?

 

So, just a checkbox that if checked keeps the user logged in forever.

 

this is my login script:

 

<?php

     session_start();


   if (isset($_POST['submit'])) {
   
       require_once('db_connect.php');
   
if (empty($_POST['email'])) {
   
    echo "didnt enter EMAKL<br />";
	} else {
	$e = trim($_POST['email']);
	}

if (empty($_POST['pass'])) {

   echo "Didnt enter PASS<br />";
   }
   else {
   $p = trim($_POST['pass']);

       }
   
   if ($e && $p) {
   
    $q = "SELECT user_id, first_name, user_level FROM users WHERE email='$e' AND pass=SHA1('$p')";

	$r = mysqli_query($dbc, $q) or trigger_error("Couldnt execute query 1");

	if (mysqli_num_rows($r) == 1) {

	   $_SESSION = mysqli_fetch_array($r);
	   
	   header("Location: index.php");
	   exit();
	   }
	   else {
	   echo "Youre not in hte DB<br />";
	   }
	   }
	   }
	   ?>

i put what you told me in the same place but it didnt work out.

 

Can you modify the script so that it contains the checkbox and the codethat always has the user logged in if checked, and post the WHOLE script ?

 

Thanks

I also tried to modify that part by puttring the cookies before such as:

 

$q = "SELECT user_id, first_name, user_level FROM users WHERE email='$e' AND pass=SHA1('$p')";

 

$r = mysqli_query($dbc, $q) or trigger_error("Couldnt execute query 1");

 

if (mysqli_num_rows($r) == 1) {

 

  $_SESSION = mysqli_fetch_array($r);

  if(isset($_POST['remember'])){

        setcookie("cookid", $_SESSION['user_id'], time()+60*60*24*100);

        setcookie("cookname", $_SESSION['first_name'], time()+60*60*24*100);

setcookie("cooklevel", $_SESSION['user_level'], time()+60*60*24*100);

         

 

  header("Location: index.php");

  exit();

  }

  }

 

 

    //IT ENDS 

  else {

 

but this didnt work out either

<?php

if (isset($_POST['submit'])) {
    require_once('db_connect.php');
    if (empty($_POST['email'])) {
        echo "didnt enter EMAKL<br />";
    } else {
        $e = trim($_POST['email']);
    }

    if (empty($_POST['pass'])) {
        echo "Didnt enter PASS<br />";
    }
    else {
        $p = trim($_POST['pass']);

    }

    if ($e && $p) {
        $q = "SELECT user_id, first_name, user_level FROM users WHERE email='$e' AND pass=SHA1('$p')";
        $r = mysqli_query($dbc, $q) or trigger_error("Couldnt execute query 1");
        if (mysqli_num_rows($r) == 1) {
            if(isset($_POST['remember'])) {
                session_set_cookie_params(86400);
            }
            session_start();
            $_SESSION = mysqli_fetch_array($r);
            setcookie("cookid", $_SESSION['user_id'], time()+60*60*24*100);
            setcookie("cookname", $_SESSION['first_name'], time()+60*60*24*100);
            setcookie("cooklevel", $_SESSION['user_level'], time()+60*60*24*100);
            header("Location: index.php");
            exit();
        }
        else {

        }

I also took the liberty to format your code to something more readable.

Hey man,

 

Thanks for modifying.

 

I still dont see it working, i tested it, i get logged in, but when i close the browser, reopen it and go to index.php, i am not logged in.

 

At the index.php page, i use this to check if the user is logged in (and it works, but i am not sure if i should modify that also because of the remember me feature:

 

<?php
session_start();

if (isset($_SESSION['first_name'])) {
  
   echo "Hello man<br />";
   
   echo "<a href=\"logout.php\">logout</a>";
   
   }
   
   
   
   ?>

 

 

I still dont see it working, i tested it, i get logged in, but when i close the browser, reopen it and go to index.php, i am not logged in.

 

Read the contents of your cookie and check for how long it is set. Or ouput the time using session_get_cookie_params() and if ttl is still 0 then session_destroy() when you login:

session_start(); 
if (sizeof($_SESSION)) {
    session_destroy();
}
..

This just confuses me further.

 

To put it simply, are you bothered (or anyone else) to rewrite my original login.php script so that it contains an option for a user to always stay logged in and also if need be modify the way i check to see if the user is logged (because of the remember me feature) ? I believe it will not take more then a few minutes.

 

Thanks for trying to help, but i am not that good with php to understand what youre pointing at.

1) Posted in the wrong section. 2) Forget my suggestion, won't work. 3) Read the contents of your cookie using firefox and some plugin which reads cookie data.

How is this posted in the wrong section ? Should i put it in the freelance section ?

 

I am not asking for someone to write an entire app for me, just help me modify this script i have already made, but  cant successfully modify.

 

Can someone help me with this ?

Try this:

 

<?php

     session_start();


   if (isset($_POST['submit'])) {
   
       require_once('db_connect.php');
   
if (empty($_POST['email'])) {
   
    echo "didnt enter EMAKL<br />";
	} else {
	$e = trim($_POST['email']);
	}

if (empty($_POST['pass'])) {

   echo "Didnt enter PASS<br />";
   }
   else {
   $p = trim($_POST['pass']);

       }
   
   if ($e && $p) {
   
    $q = "SELECT user_id, first_name, user_level FROM users WHERE email='$e' AND pass=SHA1('$p')";

	$r = mysqli_query($dbc, $q) or trigger_error("Couldnt execute query 1");

	if (mysqli_num_rows($r) == 1) {

	   $_SESSION = mysqli_fetch_array($r);
	   //i HERE IS THE CHANGE
	   if(isset($_POST['remember'])){
        setcookie("cookid", $_SESSION['user_id'], time()+60*60*24*100);
        setcookie("cookname", $_SESSION['first_name'], time()+60*60*24*100);
	setcookie("cooklevel", $_SESSION['user_level'], time()+60*60*24*100);
          }
	   
	   header("Location: index.php");
	   exit();
	   }		   
	     //THE CHANGE ENDS HERE 
	   else {
	   echo "Youre not in hte DB<br />";
	   }
	   }
	   }
	   ?>

I do try to understand the ode of course, and i will understand it if i ever get it working, i just cant make it work all the way.

 

Mattal, what exactly did you change in the code ?

 

also will someone reply to my question to which i believe also is a very big issue, do i need to change the way i check if the user is logged in if i want to use the remember me feature ?

 

Currently i check it like this (and it works, but without the remember me feature):

 

if (!isset($_SESSION('first_name'])) {

 

  header("Location: blabla.php");

exit();

}

Yeah that will still work.

}

 

I moved the section of the code which checks for the login and sets the cookies, because you had it in the wrong place (you had it after the } else {, not before it).

 

Did it work though?
