PHP - Specific Session Destryoing
Hi there im trying to destroy a specific session i have been looking through many different ways on google but have yet to find one the reason i want to do this is because my website part of the website that is being made has to have a login to view everything and this login ontop to view restricted content, so far my logout has destroyed both sessions and i cant find an answer, all the nessecory scripts are listed below
Login: <?php if(isset($_POST['code'])) { $host="***********"; // Host name $username="*************"; // Mysql username $password="************"; // Mysql password $db_name="******"; // Database name // Connect to server and select databse. mysql_connect($host, $username, $password); mysql_select_db($db_name); // username and password sent from form $myusername=$_POST['myusername']; $mypassword=$_POST['mypassword']; // To protect MySQL injection (more detail about MySQL injection) $myusername = stripslashes($myusername); $mypassword = stripslashes($mypassword); $myusername = mysql_real_escape_string($myusername); $mypassword = mysql_real_escape_string($mypassword); // encrypt password $encrypted_mypassword=md5($mypassword); $sql="SELECT * FROM members WHERE username='$myusername' and password='$encrypted_mypassword'"; $result=mysql_query($sql); // Mysql_num_row is counting table row $count=mysql_num_rows($result); // If result matched $myusername and $mypassword, table row must be 1 row if($count==1){ // Register $myusername, $mypassword and redirect to file "login_success.php" session_register("myusername"); session_register("mypassword"); header("location:jncomenu.php"); } else { echo "Wrong Username or Password"; } } ?> Check session: <? session_start(); if(!session_is_registered(myusername)){ header("location:JNCOlogin.php"); } ?> Logout: <? session_start(myusername); session_destroy(myusername); header("location:index.php"); ?> The first session is the same script bar [php][session_register("username"); session_register("password"); /php] Any help will be greatly appriciated. Thank, Blink359 Similar TutorialsI am following along in a PHP, MySQL book and the way they clear session variables is by: Code: [Select] session_start(); session_unset(); session_destroy(); They clear session variables like that in that exact order. My question is that this apparently clears ALL session variables for the browser in use. Every website I have visited when you click a LOGOUT button ONLY logs you out of their specific site and DOES NOT seem to clear ALL session variables as this would log you out of any other websites that you might be logged into with that same browser. So, I went to the PHP website and found out that instead of using the session_unset () function you can clear individual session variables using the unset ($_SESSION['varname']) function. Is this a good way of clearing session variables ONLY for a PARTICULAR website and NOT clearing session variables for the WHOLE browser? If so, would I then NOT use the session_destroy () function after clearing each individual session variable specific to that ONE website using unset ($_SESSION['varname'])? Thank you in advance! I have this simple while loop which retrieves data from a mysql query and displays several links on my homepage. I would like to avoid using the php get function and add query strings to my urls I am thinking of using session variables but I need help and I'm pretty sure this can't be done. When a visitor clicks a link from the several ones displayed by the while loop, that particular variable would be set in a session. In my code, the session will always send the last var Can this be done? Code: [Select] <? session_start(); // Start Session Variables $result = mysql_query("my query"); while($slice = mysql_fetch_assoc($result)){ $url = $slice['url']; $name = $slice['name']; ?> <a href="<? echo $url; ?>"><? echo $name; ?></a> <? } $_SESSION['name'] = $name; // Store session data ?> I use the Wholesale Suite Premium Prices plugin with WooCommerce. I have 6 specific wholesale roles out of 15 that I wish to hide two specific shipping methods from being selected for the 6 exceptions. I'm just trying this on my staging server at this time using a code snippet example that I found and modified for my specific conditions. Would the following work for this purpose?
/* Hide specific shipping methods for specific wholesale roles */
add_filter( 'woocommerce_package_rates', function( $shipping_rates ) {
// User role and shipping method ID to hide for the user role
$role_shipping_method_arr = array(
'ws_silvia_silver' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_silver_pst_exempt' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_silver_tax_exempt' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_silver' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
'ws_silvia_silver_pst_exempt' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
'ws_silvia_silver_tax_exempt' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
'ws_silvia_gold' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_gold_pst_exempt' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_gold_tax_exempt' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_gold' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
'ws_silvia_gold_pst_exempt' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
'ws_silvia_gold_tax_exempt' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
);
// Getting the current user role
$curr_user = wp_get_current_user();
$curr_user_data = get_userdata($current_user->ID);
// Wholesale Suite Roles
if (isset($current_user) && class_exists('WWP_Wholesale_Roles')) {
$wwp_wholesale_roles = WWP_Wholesale_Roles::getInstance();
$wwp_wholesale_role = $wwp_wholesale_roles->getUserWholesaleRole();
// Loop through the user role and shipping method pair
foreach( $role_shipping_method_arr as $role => $shipping_methods_to_hide ) {
// Check if defined role exist in current user role or not
if( in_array( $role, $current_user->roles) ) {
// Loop through all the shipping rates
foreach( $shipping_rates as $shipping_method_key => $shipping_method ) {
$shipping_id = $shipping_method->get_id();
// Unset the shipping method if found
if( in_array( $shipping_id, $shipping_methods_to_hide) ) {
unset($shipping_rates[$shipping_method_key]);
}
}
}
}
}
return $shipping_rates;
});
Any insights as to how to accomplish this would be greatly appreciated. Lyse I am trying to create an index page which contains registration and login field the problem that i get is on successful login a warning is displayed session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\xampp\htdocs\Eventz.com\index.php:116) in C:\xampp\htdocs\Eventz.com\index.php on line 235 This is the login part of my index.php this tag is inside an html table below the login form I also have a registration form and its php code above the login form Code: [Select] <?php if (isset($_REQUEST['pass'])) { $id=$_POST['id']; $pass=$_POST['pass']; $conn =mysql_connect("localhost","root",""); if (!$conn) { die('Could not connect: ' . mysql_error()); } /* checking connection....success! */ $e=mysql_select_db('test', $conn); if(!$e) { die(''.mysql_error()); } else { echo 'database selected successfully'; } if (isset($_REQUEST['id']) || (isset($_REQUEST['pass']))) { if($_REQUEST['id'] == "" || $_REQUEST['pass']=="") { echo "login fields cannot be empty"; } else { $sql=mysql_query("Select email,password from login where email='$id' AND password='$pass'"); $count=mysql_num_rows($sql); if($count==1) /* $count checks if username and password are in same row */ { session_start(); $_SESSION['id']=$id; echo "</br>Login Successful</br>"; } else { echo "</br>invalid</br>"; echo "please try to login again</br>"; } } } } ?> Any help or suggestion would be appreciated I am having trouble resolving an error.

I have tried to replace the header (Location: 'admin.php') with this: echo "<script>document.location.href='admin.php'</script>"; echo "<script>'Content-type: application/octet-stream'</script>"; I've been trying to read up on solutions but haven't been able to get it sorted. If anyone can offer some advice that would be greatly appreciated as im new to php. Code: [Select] <?php session_start(); if(isset($_SESSION['user'])) echo "<script>document.location.href='admin.php'</script>"; echo "<script>'Content-type: application/octet-stream'</script>"; ?> <div id="loginform"> <form action="dologin.php" method="post"> <table> <tr> <td><span>Username:</span></td> <td><input type="text" name="username" /></td> </tr> <tr> <td><span>Password:</span></td> <td><input type="password" name="password" /></td> </tr> <tr> <td colspan="2" align="right"><input type="submit" name="login" value="Login" /></td> </tr> </table> </form> </div> I have tried using require_once('yourpage.php'); before my <head></head> tags in the header document where I've specified the html information but this doesn't seem to work. I've been advised to use ob_start("ob_gzhandler"); but I am not sure how to implement this. Any advice is greatly appreciated! in this page http://maximaart.com/newscp/ i have this problem Code: [Select] Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/maximasy/public_html/newscp/index.php:1) in /home/maximasy/public_html/newscp/index.php on line 2 my source code is <?php session_start(); include_once("config.php"); include_once("functions.php"); $errorMessage = ''; if (isset($_POST['txtUserId']) && isset($_POST['txtPassword'])) { if ($_POST['txtUserId'] === "$user" && $_POST['txtPassword'] === "$pass") { // the user id and password match, $_SESSION['basic_is_logged_in'] = true; require("main.php"); exit;?> hi everyone. i'm wondering what the best way is to create a session variable and pass it to an iframe. i need to do something along these lines, but it doesn't seem to pass the ID. Any hints on how i should accomplish this? Code: [Select] session_start(); $_SESSION['ID']=$_GET['ID']; // id from previous page $ID=session_id(); <iframe src="iframepage.php?ID=<?php echo $ID; ?>" style="width:680px; height:200px;" noresize="noresize" frameborder="0" border="0" scrolling="Yes" allowtransparency="true" /> </iframe> I'm making a simple login system with MySQL and PHP (very simple, I'm just starting with PHP). The MySQL portion is done, but I need to ensure only people who are logged in can see certain content. To check if people are logged in, my website checks that they have the $_SESSION['user'] variable set. If it is set, then it lets them continue through the website, if not, it tells them to login. Is that enough security, or can people simply inject a session cookie into their browser to spoof that they are logged in? My idea was to generate a session key cookie when they login (just a random string of letters and numbers) and store that in the database, then on every page, check to make sure their session key is the same thing that's in the database. Is this necessary? It seems expensive. Evening! I've been iffing and ahhing over this and well im not too sure, hence the post. Code: [Select] // Redirects if there is no session id selected and echos the error on the previous page if(!isset($_GET['get']) || ($_GET['getget'])){ header("Location: #.php?error"); } So it should simply check if get is set if it isnt then see if getget is set? If not redirect and show the error. Now ive tried it and even when get/getget is set it still redirects, probably something silly. Care to share anyone? Harry. Just curious how other people feel about this. I am working on an application where a lot of info is pulled from MySQL and needed on multiple pages.
Would it make more sense to...
1. Pull all data ONCE and store it in SESSION variables to use on other pages
2. Pull the data from the database on each new page that needs it
I assume the preferred method is #1, but maybe there is some downside to using SESSION variables "too much"?
Side question that's kind of related: As far as URLs, is it preferable to have data stored in them (i.e. domain.com/somepage.php?somedata=something&otherdata=thisdata) or use SESSION variables to store that data so the URLs can stay general/clean (i.e. domain.com/somepage.php)?
Both are probably loaded questions but any possible insight would be appreciated.
Thanks!

Edited by galvin, 04 November 2014 - 10:30 AM. How can i call a specific row when ever a like. example : Code: [Select] $record = mysql_query("select * from table_name"); ($getValue= mysql_fetch_row($record) //i'm not sure what should i use. should i use mysql_fetch_array, mysql_ fetch_ assoc, mysql_ fetch_ object, mysql_ field_ name and etc. print $getValue[$column_name][0]; 0 = value 1st row in the database/table_name 1 = value 2nd row in the database/table_name 2 = value 3rd row in the database/table_name ...... .... ...... ..... etc. is there a code i can do except from using sql_fetch_array then loop and put in into a multidimensional array? Hello all! Well, here's my dilemma. I understand how PHP and server side code works, I understand the important basics about PHP in general, I just need more specific help. I'm currently working with a partner in building a website that allows users to basically enter in information in text fields, add a picture to their post, and choose from a drop down menu what other page on the website they want the post to go to. (For all of the things I'm discussing here, I've drawn out pictures of what I want in Illustrator if anyone needs specifications.) Once the user presses "Submit" or "Accept" or whatever, it will post their information on the page they selected, organized with the picture a certain size on the left, and the text aligned ragged right on the right side of the picture. Below that, each "post" will be assigned a number based on the last post made to that page. So if I was the first one to post it, it'd show "1" in the data. I can imagine this isn't a simple process, but because I understand how PHP works, and also how comment systems in server side coding works, I just need to know certain things in the code, like organizing the inputed data when posted and what not. Any help or advice would be greatly appreciated by both me and my partner. Thanks! I've been searching for a couple of days on google using keywords, trying to figure out why this form sends blank emails. I've found several different ways to write something like this, including what's below, but for the life of me I haven't figured it out. Can anyone help a brother out? <?php $email = $_REQUEST['email']; $message = $_REQUEST['date']; $message .= $_REQUEST['location']; $message .= $_REQUEST['quantitymodel']; mail( "name@email.com", "Email Contact Form", $message, "From: $email" ); header( "Location: thankyou.html" ); ?> Was just wondering if it's okay to make simple donations to other users on the forum. Just out of generosity.
If true, if I want to make a donation to a specific user how would I go about doing it? Just pm them asking for their paypal?
Edited by Monkuar, 12 October 2014 - 12:08 PM. Hi guys, i was having an issue with dates and although it leans a bit more into MYSQL I was hoping i could get some help ive searched all over the net for this so I dont know if im not thinking on how to ask this correctly or can't find it, but ill be as detailed as possible and hope that helps.
Ok I have a table that shows when payment was received on past invoices dating back to say 1995; The company processes 'ALL' invoices every month on the 9th, so if anything comes in from the first to the ninth it will be processed that month on the ninth. If it comes in from the tenth to the thirtieth or thirty-first it will be processed the following month.
The table already has a "Received" date filed and now I want to create a column on the table called "Processed Date" (adding the column is no problem don't need help with that part) that shows me the date we processed the invoice.
I know i have to use the "Received" field (because it shows what day the invoice was put into the system) but im not sure how to format the "Processed Date" field, so say the "Received" field shows an invoice came in on '1995-05-11', I want the "Processed Date" field to display it was payed on '1995-06-09' (notice that is the following month).
I thought i would put in a visual of what I was trying to do below:
So if I pull the two columns in MYSQL from that table I would see something like this:
Received Processed Date
1996-02-03 1996-02-09
1996-03-03 1996-03-09
1996-04-11 1996-05-09
1996-05-20 1996-06-09
1996-07-13 1996-08-09
If i could get some guidance/help on this i would really appreciate it.
thanks in advance!!

Hi guys
I'll try keep this simple
I have been given access to a betting xml feed which requires my IP to be whitelisted.
I have whitelisted my home IP and it works fine.
I have whitelisted an IP on server 1 (linux, cpanel), this works fine
I have whitelisted an IP on server 2 (linux, cpanel), this doesn't work and I get:
"simplexml_load_file failed to open stream: http request failed!"
The IP is definitely whitelisted but I think it is something to do with the server. What could be blocking this?
allow_url_fopen and allow_url_include are both on by the way
Many thanks
Sam
Hey guys I have trouble picking the specific id of an entry i want to delete so please take a look at the codes first Here's the function for making the form: Code: [Select] function am_query_display_quick($page,$order ='DATE DESC'){ global $email; $conn = db_connect_2(); $color1 = "tableRowOdd"; $color2 = "tableRowEven"; $RowCount = 0; $result = $conn->query("SELECT pro,pro_update,ana,ana_update,cell,cell_update,cellother,cellother_update,gen,gen_update,genother,genother_update,author,author_update,other,other_update,id FROM mailing_list WHERE email = '$email' ORDER BY $order LIMIT $start_row, $max_per_page;"); echo "<form method = \"post\" action=\".{$_SERVER['PHP_SELF']}.\">"; echo "<table class=\"sortable\" id=\"query_quick2\" width=\"100%\" >\r\n"; echo "\t<tr><th></th><th>Promoter Locus</th><th>Update?</th><th>Anatomical Area</th><th>Update?</th><th>Cell Type</th><th>Update?</th><th>Other Cell Type</th><th>Update?</th><th>Genetic Background</th><th>Update?</th><th>Other Gen. Back.</th><th>Update?</th><th>Author</th><th>Update?</th><th>Other</th><th>Update?</th><th></th>\r\n"; if($result->num_rows){ while ($row = $result->fetch_array()){ $RowCount ++; $row_color = ($RowCount % 2) ? $color1 : $color2; echo "\t<tr class=\"$row_color\" ><td><input type=\"submit\" name=\"edit_mail\" value = \"Edit\"/></td> <td>{$row['pro']}</td><td>{$row['pro_update']}</td><td>{$row['ana']}</td> <td>{$row['ana_update']}</td><td>{$row['cell']}</td><td>{$row['cell_update']}</td><td>{$row['cellother']}</td> <td>{$row['cellother_update']}</td><td>{$row['gen']}</td><td>{$row['gen_update']}</td><td>{$row['genother']}</td> <td>{$row['genother_update']}</td><td>{$row['author']}</td><td>{$row['author_update']}</td><td>{$row['other']}</td><td>{$row['other_update']}</td> <td><input type=\"submit\" name=\"delete_mail\" value =\"Delete\"/></td> <td><input type =\"hidden\" name = \"id\" value=\"{$row['id']}\"/></td> </tr>"; } } echo "</table>"; echo "</form>"; And this is where the delete command comes into place (excerpt): Code: [Select] } elseif(isset($_SESSION['user_id']) AND isset($_POST['delete_mail'])){ //user is deleting existing queries $conn=db_connect_2(); $id = mysqli_real_escape_string($conn, $_POST['id']); echo $id; $sql2 = "DELETE FROM mailing_list WHERE id='$id'"; $result = mysqli_query($conn, $sql2) or mysqli_error($conn); $msgs[] = "Query deleted successfully."; $body = "account.php"; } yes it can delete entries all right but it doesn't delete a specific entry when i click the "delete" button near it somehow, it ALWAYS deletes the last row of entry at the table as you can see, i echoed out $id as it's referring to the LAST entry as well So my question is, how to delete a particular entry when i click the corresponding "delete" button?? Thanks Hy i have a GIT repo on a specific location and i need to exec it. so i tooth it was like exec git reset --hard but it executes the command as it was on the base root location. I need before i execute the command to go to my GIT repo location. Can someone help me out? I read about it here http://www.linuxjournal.com/content/bash-redirections-using-exec and if i get it i need a named pipe... but i don't get how i can do it ~.~ i am a exec newbie. Hello all, I have a rather large array and I need to list it's contents in an alphabetical list. The array is built like this: $array['query']['row']['0']['title'] = 'Bob'; $array['query']['row']['1']['title'] = 'Andy'; $array['query']['row']['2']['title'] = 'Tom'; I need to sort it so it is in alphabetical order based on the title. Is there an easy way to do this? |
