PHP - Student Cohort Tracking
I have a small database snippet over at SQLFiddle: http://sqlfiddle.com/#!2/9ff722/55
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. Similar TutorialsHi All I am kinda new to php.... I disparately need help with php coding. I am entering in the website using student id. If student id does not exist in mysql database, it gives me error. That works fine. But If I try to echo StudentID on 2nd page, it is not displaying anything. Second problem is I want to display student first and last name using StudentID. But it is not displaying anything using StudentID. Why? I have been trying to solve it, but no success Following is the code for both problems - if(!$db_selected) { die("Can not use".DB_NAME.':'.mysql_err()); } @$Stud_ID = $_POST['Stud_ID']; ?> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <link rel="stylesheet" type="text/css" href="ACSDP.css" /> <title>Student Main Page</title> <head><h1>Welcome to Undergraduate Student Main Page</h1> </head> <body> <form name ="mainpage" method='POST'> <table> <tr> <td><label id="Stud_ID2" for="Stud_ID"> Student ID <?php echo "is:" ."

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!

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. Hi, here's my problem let's say I gave an end user a url such as e.g http://www.test.com/index.php?user=asdf1234 and I did the same thing to different end users with unique $_GET['user'] value each . my question is, how to track the URLs ?, i mean, how will i know if those urls were clicked and how to count the clicks made ? some possible scenarios could be - the url is pasted and send via email - the url is embeded as a link in some portals Hey guys! I had a quick question that is more about php coding theory than actual code. Anyway, I was curious as to how one would track ad clicks and impressions (especially the impressions). There are tons of sites that do this but I don't really understand how. Thanks Hi, how can I track my order with DHL API? I want to implement SOAP request in PHP. Can you help me? Edited June 11 by requinixsplit from https://forums.phpfreaks.com/topic/310639-mydhl-soap-request/ I've been reading about trackbacks and pings but what I'm trying to do is a bit different. I'm trying to track a referral link. For example, I post this referral link http://www.my-site.com/3ji89 on youtube or a blog.. and that referral links to.. http://www.another-site.com in http://www.another-site.com is it possible to retrieve the referral link http://www.my-site.com/3ji89 ? Not youtube.com or the blog I posted the link on. hi i need a script to track how many times a link has been clicked, if this is possible can i have some guidance cheers matt Hello.. Anyone knows a little bit about pixel tracking?? I need to implement it in my email.... This topic has been moved to Miscellaneous. http://www.phpfreaks.com/forums/index.php?topic=350102.0 I am looking to save the user's access of an application. For instance, when they log in, I create a record in the "track_login" table which includes information such as the requesting IP, the user's ID, the date, (not the user's password), etc. And then for every page they visit, I store a record in the "track_page_viewed" table which includes a FK to the "track_login" table and also includes additional information about their request.
Both the track_login and track_page_viewed tables are currently in the same database as used by the primary application.
So far, so good.
Next, I want to start tracking when a user does special tasks such as when they forget their password and request that a new one be emailed to them. Or maybe when they attempt to login with an invalid username and password. Currently, I just included another table called "track_special" which includes the data, the type of special request, etc.
Now, I am thinking of adding three other things to track:
General PHP errors
MySQL errors
Try/Catch errors which I did not expect to happen
One option is just to add these to my "track_special" table or maybe make one or three new tables in the same database.
But is this a good idea? If I have a SQL error, do I really want to store the error in the same database? Maybe I should use a separate database called "myTrackerDB", and include all the above tables in that database? Or maybe I should just write the data to a flat file, and parse the file on a regular basis, and then store the information in the database?
Please provide any recommendations, guidance, suggestions, criticism, etc. Thank you
Hey guys im a little stumped. My pages has the following links. <a href="?page=yes">Yes</a> to Change content i use <?php if (isset($_GET['page'])) { include ("include/".$_GET['page'].".php"); } else { echo 'Welcome to Liquids Scripts PHP Code repository. Just select the categorie from the top and get all the info required '; } ?> Will this be tracked by google analytics? Any help would be awsome. Hello everyone. I have a small problem. I might receive a ?aff=## or not on the end of my url when I get a visitor to my website. This depends on if they are sent from a affiliate website or not. If they are it shows fine on the home page but I loss it if they go to another page on my website. I need to keep this ?aff=## information while they look at the other pages. How would I capture and pass this information to my other pages as they surf my site? I tried this to no avail. $aff=$_GET['aff']; I have no clue no adding it back to the next page they go to. Any ideas would be helpful.. This topic has been moved to Miscellaneous. http://www.phpfreaks.com/forums/index.php?topic=311981.0 Hey guys, I am not a coder at all and would love a little bit of help with my code not working. Basically, I have a redirect script that sends my visitors to a software download. I want to be able to track a snippet from the incoming refer and send it along with the download. I hope I am explaining this correctly. Here is my code: <?php $tid = $_GET["tid"]; header( 'Location: http://www.liutilities.com/affcb/?id=RBgendtd&aff=14231&xat=WU-<?php echo $tid; ?>' ); ?> The page that sends them to this script automatically adds ?tid={keyword here}. What the above script is supposed to do is grab tid and then put it after the &xat=WU- but instead, its only putting the actual code itself (&xat=WU-<?php echo $tid; ?>). Can anyone offer a suggestion? Thanks so much! As we have been working on an eCommerce project, we want to add an option in the eCommerce, that user should have the live location tracking of delivery boy (as same as SWIGGY) in the website. Is there any chance to track the live location using PHP and JavaScript? Searched on the google but nothing resolved my problem? Please anyone suggest us to track the live location of the delivery boy. Thanks in advance Hi, I'm trying to make/ am looking for a script (that's free) to provide users with a button to donate, once they have donated they are then returned to the website and the donation amount is stored in a database. I have no idea how i would get this made and the paypal website wasn't much help either. If anyone knows of a free script or can help me make one i would be very greatful. Hi everyone, I'm developing an affiliate tracking process and after a lot of thought, I was wondering if someone might be able suggest if I'm on the right track. I'm trying to get away from the usual ...?id=135845 type of links. I was thinking about two possibilities: 1. (I don't know if this is possible), but to generate a subdomain with php at the time an affiliate signs up and then track them by extracting the subdomain to identify the affiliate, or 2. Somehow, maybe using a mod rewrite, using the affiliate username at the end of a url, ex. www.website.com/username , you can see that there is no extension, but when a person comes to that url, it will display the contents of www.website.com and I'd extract the username 'username' from the url and query the database to identify the affiliate. Any thoughts on how this can be done? |
