Hi experts,I have the following problem.I have a file login.php which is used to allow users to log in.When the form is submitted it is redirected to checkuserlogin.php.If the credentials are right he is redirected to main.php.But in main.php if the user clicks back browser button,he is redirected to login.php and in login.php if he presses forward button,he is redirected to main.php.Can any one tell he how to make sure the application is not redirected to main.php when user presses forward button and how to make sure the application is not redirected to login.php when user presses back button.
In my login form I'm getting the error Code: [Select] Notice: Use of undefined constant Errors - assumed 'Errors' in /home/content/n/a/t/nathanwatson/html/admin/YBK/post.php on line 91 Warning: Cannot modify header information - headers already sent by (output started at /home/content/n/a/t/nathanwatson/html/admin/YBK/post.php:91) in /home/content/n/a/t/nathanwatson/html/admin/YBK/post.php on line 91 Warning: Cannot modify header information - headers already sent by (output started at /home/content/n/a/t/nathanwatson/html/admin/YBK/post.php:91) in /home/content/n/a/t/nathanwatson/html/admin/YBK/post.php on line 92 //if the name exists it gives an error if ($check2 != 0) { //Line 85 $error="<span style="; $error .="color:red"; $error .=">"; $error .= "Sorry, the username is already in use."; $error .="</span>"; setcookie(Errors, $error, time()+20); //Line 91 header('Location: /YBK/'); //Line 92 exit; } i just discovered a hole in my scripts relating to access . 1. have a simple login form 2. based on the type of user , he is directed to a page for his options . 3. I now realise that altho each page therefter checks for sessions of the user , he can easily change the url to that of another user and there is no way to prevent it. 4. How can i make sure that each time a page is accessed it is only by the user whom it is meant for. Relevant code snippets below . Thanks !

When they login it works without issue. I just don't know where or what to put for the registration part.
Here is my Code. Any help would be much appreciated.
<?php I am createing a simply quiz site, where in order to participate in the quiz, you must first be logged in. While working on my local machine, the code works perfectly. I use the followin to create a session ID; $_SESSION['SESS_ID'] = $member['id']; Then, on my main page where i want dynamic code i include the following; if(!isset($_SESSION['SESS_ID']) || (trim($_SESSION['SESS_ID']) == '')) { print (" <div style='float:left; width:400px; height:215px; margin-left:500px;'> <form class='login' method='post' action='login-form.php' style='float:right; margin-top:120px;' > <input type='submit' class='button' name='submit' value='Sign In' style='float:right ; margin-right:20px;'> </form> <p style=' margin-top:170px; margin-left:160px;'>New Member?

Hi all, Sorry to be a pain, but I've been out of the php game for quite a few years and have just come back to it briefly to help someone out. I've been using an old admin auth script that I used to use a long time ago but it's not working, and I can't for the life of me work it out :/ I apologise for the noobishness of the code, but as I said, it's been a long time. Any and all help would be very greatly appreciated.

This is for a assignment which is why I have to store the information in a text document, I know it's unsafe. Also i know i should use $_Sessions but I'm not sure how to use it and where to put it.
So far I have created the form which has 2 buttons one for registering and one for logging in. I have also created the registration function which checks the text file if the username already exists if not it will register it.

Hi I get the following error when running this file. Fatal error: Call to undefined function mysqql_query() in C:\wamp\www\Isis\login.php on line 14] I'm not sure if i have missed something or typed something wrong but a second opinion is always better <?php $username = $_POST['username']; $password = $_POST['password']; $login = $_GET['login']; setcookie("username", "$username", time()+86400); if ($login=='yes') { $con = mysql_connect("localhost","root",""); mysql_select_db("obsosuser"); $get = mysqql_query("SELECT count(id) FROM obsosuser WHERE username='$username' and password='$password'"); if ($result!=1){ echo "Invalid Login!"; } else echo "Login Successful! Welcome back ".$_COOKIE['username']." Sir/Maddam." ; $_SESSION ['username'] = $username; } ?> Thanks Is there a way to get current logged in username and based on that redirect to a different page? I’m using the following secure PHP login without MySql as a login system: https://sourceforge.net/projects/phploginbyvallastech/ Now I’m looking to redirect each logged in user to their personalized page. But I can’t figure out how to A) fetch the current logged in user and B) redirect multiple users. This code redirects to the latter address, but the username based redirect is not working: <?php session_start(); if ($_SESSION["username"]==User1){ header("location: user1content.php"); exit; } else { header("location: generalcontent.php"); exit; } { ?> <?php } ?>
So it’s clearly not fetching the logged in user. Though <?php echo $login->username; ?> fetches the username just fine. Hi All, I Have an issue validating and inserting the data in to the database. I am beginner and the error message is new to me however i have google it but unable to find hope any one can help Thanks in advanced.

I need help with writing a query that will allow me to track students in a certain cohort from beginning to graduation. I have two tables: application and stu_acad_cred. The application has the start term and the stu_acad_cred are course registrations. If I want to track students in a fall 2012 (12/FA) cohort, then the query must join the two tables; if the student has a start term of 12/FA *and* has registered for 12/FA courses, the student should be counted. I then want to track those student from year to year or term to term to see if the number of students that started in the 12/FA cohort actually decrease overtime. So, the results should return something similar to below.
| # Students (12/FA Cohort) | Year | ------------------------------------- | 2 | 2012 | | 2 | 2013 | | 2 | 2014 |I am not sure if this can be done straight forward or with a stored procedure but any help or direction is greatly appreciated. Hi All
I am having problems running a query to get the courses a student is enrolled for.
The format I need is somthing like this:
firstname - lastname - course ------------------------------------------- Joe Bloke US232456 Joe Bloke US554665 Joe Bloke US332098or like this firstname - lastname - course ------------------------------------------------- Joe Bloke US232456 US554665 US332098The query I am running is SELECT usr.firstname, usr.lastname, c.shortname FROM mdl_course c INNER JOIN mdl_context cx ON c.id = cx.instanceid AND cx.contextlevel = '50' INNER JOIN mdl_role_assignments ra ON cx.id = ra.contextid INNER JOIN mdl_role r ON ra.roleid = r.id INNER JOIN mdl_user usr ON ra.userid = usr.id WHERE r.name = 'Learner' AND usr.firstname = 'G01 Moloko' ORDER BY usr.firstname, c.shortnameThe problem is that I know this student is enrolled for 3 courses, but it only returns 1 course. Any help is welcomed. huck Hello sir, My name is Soji. I'm working on a php project on result transcript processing. I got to a stage where i need to rank student based on their score (Subject Position) and also Overall Position. I have tried all i could but i still don't get it I have a table called Subject position where with field (id, studentregNo, subjectid, levelid, armsid, yearid, total). what i want is if there is 3 student in a class and the first student score 50 in english and the second student score 45 and the third score 40. i want the system to tell me that the first student position in English is 1st and the second student position in English is 2nd and third student position in English is 3rd. So all this will be applicable to all subjects that the students in a particular level are offering.
Moreover, I need Rank student in a subject in that class, And this will work with each subject for each student in that class. I have mysql table titled fee_payment.
details of the table:
fee_payment Table
payment_id student_id name class term year date amount
1 6 john JHS2 2nd_term 2013 23-04-2013 56 67
2 6 john JHS2 2nd_term 2013 23-04-2013 56 34
3 5 peter JHS3 3rd_term 2014 23-04-2014 56 85
4 6 john JHS2 2nd_term 2014 23-04-2014 56 76
5 6 john JHS2 3rd_term 2014 23-04-2014 56 34
6 6 john JHS2 2nd_term 2014 23-04-2014 56 23
7 5 peter JHS2 3rd_term 2014 23-04-2014 56 43
what i need to do now is to sum total amount paid by each student so that i can view payment records based on term and year.
what i have tried:
