PHP - Moved: Tracking User Activity Like Time Spend And Number Of Visits To Page.
This topic has been moved to Application Design.
http://www.phpfreaks.com/forums/index.php?topic=326408.0 Similar TutorialsI added some code last night that updates the "last_activity" field in the "member" table whenever the "body_header.inc.php" script is called, which means that pretty much whenever the User navigates to a new page or submits a form this field is updated. (I use this to kep my "User Online Status" up-to-date.) Everything was working fine until I suddenly started getting a "Cannot modify header" error before bed. Here is ONE sequence causing this error... - I am logged out - I am on http://local.debbie/index.php - I click on the "Log In" link - I am taken to http://local.debbie/members/log_in.php - I log in - I get this error...

The "Update Last Activity" code was added to my Header last night and is likely the culprit... Any ideas what is wrong?? Thanks, Debbie Hello, I'm working on this PHP website of my college. Where in after sending the order to the vendor an e-mail is sent to the person who ordered and the head of that department notifying them about the details of order along with that now I need to send a tracking number of every order in that e-mail which gets automatically incremented in subsequent orders. So please let me know how should I approach or do this. Thank you. I need like, http://www.trackcourier.in/ The customer chooses selected courier service and enters tracking id then clicks its redirect to the appropriate courier service website. eg: If tracking id 12345 the redirect link should be https://www.fedex.com/apps/fedextrack/index.html?tracknumbers=12345&cntry_code=in How to do for India courier services? I am in need of suggestions on how too achive this: I have a surf exchange and whenever a member has viewv a site, it ads this members Id and time to a table called vtp_tracking. I have now created a team script, so I can count the total of surf for members within this team from the vtp_table. What I am in need of is this: I would like to add a bonus for the teams, so my idea was this: every hour run a cronjob to get the results for the last hour by team id lik so: Code: [Select] WHERE vtp_members.team_id="teamid" AND vtp_tracking.credit_members_id=vtp_members.id AND vtp_tracking.action_date>date_sub(NOW(),interval 60 minute I believe the above code will work fine and get me the results for team members for the last hour. Problem: how can I get this result, multiple it with the value from another field and divide by 100 and add this to a third field? eg: (result from above * value from other field / 100) then add to a third field. Anyone willing to try and answer this one?

I have this code: Code: [Select] $sql = "SELECT * FROM store WHERE id LIKE '$id'"; $result = mysql_query($sql); while ($rows = mysql_fetch_array($result)) { echo $rows['title']; } before the title i would like to have a number, starting at 1. so for example if it echoed out 10 titles each would have a corresponding number - 1, 2, 3, etc. anyone know an easy solution? thanks Hi Folks, I understand the basic math to accomplish what I want, at least I think I do I would like to confirm my logic and I need help with the final output format. I am coding a simple browser based, resource type of game. The gamer will select a certain item to produce another item and it will take x time to do it. Here is the basics of what I want, minus the coding to make it look pretty. How do I format $y to show HHH:MM:SS? Code: [Select] $complete = time() + $x; // To show how much time is remaining until completion or complete $y = $complete - time(); if $y > 0 { echo $y; } else { echo "complete"; } The Script:
<?php
echo "<h1>The Hashtag: </h1>";
echo $_GET['hashtag'];
?>
An example for the URL on localhost:
/search.php?hashtag=#xboxIf I am not using the number sign, then the word "xbox" does get printed on screen, if I do use the number sign then the hashtag "#xbox" does not get printed on screen. Any suggestions on how to do this? hello all - I have a social network for the cystic fibrosis community and we've had a spammer the passed couple of days. I have captchas set up and they work well, but in addition to those I want to limit the amount of blogs a user is allowed to post a day. I have been able to count and echo out the amount a user has made, but for some reason, when I use an if statement to stop the blog from posting it still post's. I have been working on this going on hour 8 now and need some major help Thanks in advnace. Here is my code Code: [Select] if(isset($_POST['subComposeBlog'])) { $query = "SELECT COUNT(`id`) FROM `cysticBlogs` WHERE `Author` = '".$auth."' && `date` = NOW() && `status` = 'active'"; $request = mysql_query($query,$connection) or die(mysql_error()); $result = mysql_fetch_array($request); $valid = true; if($_POST['Category'] == "null") { $valid = false; $error_msgs[] = "Whoops! Please select a category for this blog."; } if(empty($_POST['blogTitle'])) { $valid = false; $error_msgs[] = "Whoops! Cannot submit a blog without a title,how are you going to attract people's attention to read your masterpiece?"; } if(empty($_POST['blogBody'])) { $valid = false; $error_msgs[] = "Whoops! Cannot submit a blog without a body,that would not be a blog now would it?"; } if($result['COUNT(`id`)'] > 3) { $valid = false; echo "Whoops! You can only write three blogs per day due to spam"; } if($valid) { $query = "INSERT INTO `cysticBlogs` ( `blogTitle`, `blogBody`, `date`, `time`, `Author`, `Category` ) VALUES ( '" . mysql_real_escape_string($_POST['blogTitle']) ."', '" . mysql_real_escape_string($_POST['blogBody']) ."', '" . date("Y-m-d") ."', '" . date("G:i:s") ."', '" . $auth->id ."', '" . mysql_real_escape_string($_POST['Category']) ."')"; mysql_query($query, $connection) or die (mysql_error()); header("Location: BlogsSecurity.php"); } } Hello, I have a problem with writing a function that will display the number of attempts to communicate with the host that have not been answered, if the host starts responding again, the table should display, for example 0. The website addresses are taken from the MySQL database. The next column should display the time from which the communication with the host was lost and if it responds, it should display, e.g. OK. Please, give me some hints how to write it. Thanks in advance. Edited October 12, 2019 by xyz91Hi guys, I am trying to put together a little system that allows users to log onto my website and access there own personal page. I am creating each page myself and uploading content specific to them which cannot be viewed by anyone else. I have got the system to work up as far as: 1/ The user logs in 2/ Once logged in they are re-directed to their own page using 'theirusername.php' Thats all good and working how I need it too. The problem I have is this. If I log onto the website using USER A details - I get taken to USER A's page like I should but - If I then go to my browser and type in USERBdetails.php I can then access USER B's page. This cannot happen!! I need for USER A not to be able to access USER B profile - there is obviously no point in the login otherwise! If you are not logged in you obviously cannot access any secure page. That much is working! Please find below the code I am using: LOGIN <?php session_start(); function dbconnect() { $link = mysql_connect("localhost", "username", "password") or die ("Error: ".mysql_error()); } ?> <?php if(isset($_SESSION['loggedin'])) { header("Location:" . strtolower($username) . ".php"); if(isset($_POST['submit'])) { $username = mysql_real_escape_string($_POST['username']); $password = mysql_real_escape_string($_POST['password']); $mysql = mysql_query("SELECT * FROM clients WHERE username = '{$username}' AND password = '{$password}'"); if(mysql_num_rows($mysql) < 1) { die("Password or Username incorrect! Please <a href='login.php'>click here</a> to try again"); } $_SESSION['loggedin'] = "YES"; $_SESSION['username'] = $username; $_SESSION['name'] header("Location:" . strtolower($username) . ".php"); } ?> HEADER ON EACH PHP PAGE <?php session_start(); if(!isset($_SESSION['loggedin'])) { die(Access to this page is restricted without a valid username and password); ?> --------------------------------------------------- Am I right in thinking it is something to do with the "loggedin" part? The system I have here is adapted from a normal login system I have been using for years. The original just checks the details and then does a 'session start'. This one obviously has to re-direct to a user specific page. To do this I used the <<header("Location:" . strtolower($username) . ".php");>> line to redirect to a page such as "usera.php" or "userb.php" Any help would be greatly appreciated! Ta 1 Total number of likes work, but I'm guessing it can be done differently, any input would be appreciated. /controllers/indexController.php
$posts = Post::find('all', [
'limit' => 4,
'include' => ['likes']
]);
foreach ($posts as $post) {
$post->assign_attribute('likeCount', count($post->likes));
}
}
/models/Post.php
class Post extends ActiveRecord\Model {
static $has_many = [
['comments', 'class_name' => 'PostComments'],
['likes', 'class_name' => 'UserLikePosts']
];
}
/models/UserLikePosts.php
class UserLikePosts extends ActiveRecord\Model {
static $belongs_to = [
['user'],
['post']
];
}
2The big question is, how can I get a true/false for "if current user has liked post"? I was thinking something like this, but using vars won't work here, and I would have to use a ternary or a function call to do it like this as the session var might not be set (guest).
class Post extends ActiveRecord\Model {
static $has_many = [
['comments'],
['likes', 'class_name' => 'UserLikePosts'],
['user_likes', 'class_name' => 'UserLikePosts', 'conditions' => ['user_id = ?', [$_SESSION['user']['id']]]
];
}

Hello everyone, I have a messaging site where I have an email generated every night to report new activity on my site. The way it is currently set up, I have each message reply attached to the previous message, such as quoting the original text in an email message. Each string of messages in my database has one common field ("string"), but each new reply has a different message ID field in the database ("messid"). When each new message and reply is created the "reported" field in my database has a default value of n, meaning that it has not been reported yet. At the end of the day, when the email is generated, the reported field is then updated to y, meaning that it HAS been reported. The problem that I'm having now, is that I'm getting several of the same messages in every report. I am using the following code to select each unreported message from the database to generate my report: Code: [Select] <?php $result = mysql_query("SELECT `to`,`studentname`,`staffname`,`subject`,`message`,`date` FROM caresa6_$acct.allmsgs WHERE reported = 'n' ORDER BY `messid` ASC") or die (mysql_error()); ?> Basically, I need to know how to select only the most recent unreported message within each string of messages. For example, now if there is a new message: "Hello there." Then a reply from the recipient: "Hi! How are you?" Then another reply from the original sender: "I am fine." My report will look like this: ___________ New Message: "Hello there." ------------------ Reply: "Hi! How are you?" ------------------ Reply: "I am fine." ------------------ ___________ New Message: "Hello there." ------------------ Reply: "Hi! How are you?" ------------------ ___________ New Message: "Hello there." ------------------ So I am getting carbon copies of every new message every time someone replies. I want to only select the most recent message so that my report only reads: ___________ New Message: "Hello there." ------------------ Reply: "Hi! How are you?" ------------------ Reply: "I am fine." ------------------ Thanks in advance. Hi, when a user logs out, I want to store the last activity in for the user. I have a db table users: userID userName userPassword lastSession lastActivity ===== ======= ========== ======== ======= 1 bob password 2011-08-09 About.html 2 dre passwords 2011-09-23 Home.php here is logout script: =============== Code: [Select] <?php //run this script only if the logout button has been clicked if(array_key_exists('logout', $_POST)) { require("connect.inc"); $username=$_POST["username"]; $updateLastSessionQuery=mysql_query("UPDATE users SET lastSession=NOW() WHERE userName='$username'"); // end session and redirect //empty the $_SESSION array $_SESSION = array(); session_destroy(); header("Location: xmlShredderLogin.php"); exit; }//END IF for when logout submitted ?> here is Index.php: ============= Code: [Select] <?php session_start(); if(isset($_SESSION["isAuthenticated"])) { require("logout.inc.php"); $username=$_POST["username"]; //print $username."<br />"; print ' <html> <head><title>Home</title></head> <body> <form id="logoutForm" name="logoutForm" method="post" action=""> <input name="logout" type="submit" id="logout" value="Log out" /> <input type="hidden" name="usernameHidden" value='; print$username; print '/> </form>'; mysql_connect("localhost","root"); mysql_select_db("someDB"); $getUserInfoQuery=mysql_query("SELECT lastSession,lastActivity FROM users WHERE userName='$userName'"); $getUserInfo=mysql_fetch_assoc($getUserInfoQuery); print "Last session: ".$getUserInfo["lastSession"]."<br />"; print "Last activity: ".$getUserInfo["lastActivity"]."<br />"; Let's say the last page the user is on is Index.php, so what do I use to track the last page they are on?? I can't user a form b/c if I have to type in the last activity, that's nonsense! So far I have only figured out how to store the current time in last session (but this doesn't work either). I just want to track the last page and then have a switch such as: switch(type) case 1: $lastActivity="About.html"; case 2: $lastActivity="somethingelse.php"; Any help much appreciated! Hello, I had 8 select boxes(dropdowns) in a form. Its like a search kind of implementation in the website. I don't know what the user selects, he may choose different select boxes, any number of select boxes. So, based upon the user selection, I need to generate the data. The data fields to be generated would be almost same. So, How would I know what the user selection is and how many select boxes has been selected and how could I generate different data based upon selected boxes. I had to make a small note abt this, that the data generation fields may change for some of the user select combinations, but most of the result fields would be same. so, can you please help me out, how to do, how to make different combination data generations, because, i had 8 fields, i had to make 8! combinations, that would result in a big code. I would really appreciate help and I hope my problem can be solved easily. I am attempting to display the date/time based on the user's location. I have installed the timezone.js plugin for help as well. Is there a way to convert the Jquery variable that displays the users timezone location and insert it inside the PHP date_default_timezone_set?
If there is an easier way to display the users timezone date and time please let me know otherwise this was the only solution I could find.
Thanks in advanced...
