PHP - Clearing Session Variables Specific To One Website

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,

I'm new to PHP and I have an html page I would like to pull specific data into certain areas on the page that I will modified for php.

Here are some details. The page is a static html page that has the prices of 40+ products in a standard <li> list. When I update the prices in our database through our shopping cart, I have to change these prices manually in the html. https://www.novon.co...mic_mixers.html. It would be great if I could link the field for Base_Price in the products table to each affiliated <li> tag,

I am pulling all the data I need into ($results) and can display it all but I don't know how to get just the single products Base_Price in my <li> tag. <?=$row['Base_Price'] ?>

I know this code is not correct but to get the point across, can I create a variable that I define in each <li> tag with a statement like,,,, <?=$row['Base_Price with Product_Code=123456'] ?>

I could create a new SQL query for each <li> like "SELECT Base_Price from Products WHERE Product_Code='123456' ", but that's a lot of calls to the DB and a lot of code on the page.

And just so I weed out the hard core coders, I can not rebuild the entire page. This is too big of a project for me and my limited coding with PHP.

Can anyone help??
Thanks in advance

hi professionals   I was not sure where to exactly post this as I am not to sure if it is a php question.   We are developing a new website for another country and are looking to geo target people with the country in mind   for instance if I visit comparethemarket .com or comparethemarket uk from here in Australia a pop up window appears saying the following    

I am wondering if it's possible to get some data from another website via PHP? I would like to get data from website http://www.gamersfirst.com/warrock/?q=Player&nickname=soldier, and the exact data which I need is "Level" which is in this case 2. Can this value be grabbed and if it can, where can I get some info about how to do it?

they recently reset my website so my php.ini file has been adjusted. One of my sites is no longer passing a session variable to the next page. I am sure its one of the settings being reset. here is the data from my phpinfo file. Anything that looks off to anyone?

Say I have a dropdown menu consisting of user specific options. I need to be able to set a session variable depending on the option chosen & then re-access it on the following page. Can someone give me a crash course on how to utilize session variables?

...anyone know anything about Internet Explorer not printing values from session variables.  It works on Firefox but not on Internet Explorer.  The session variable value works find on the web page but click on Print preview and it dissapears and will not print.

Hi

Can some steer me in the right direction.  I am having issues subtotaling 2 session variables:

<td>'.$_SESSION['itemqty'][$key].'*'.$_SESSION['itemprice'][$key].'</td>

Can you advise if I am doing this right?

Cheers

Hi.  I'm brand new to this forum, so sorry if I do something wrong...

I'm someone who has thought myself to code in php to add dynamic objects to my basic static websites.  I have had no formal education.  This is not my first project however. 

I'm having problems with session variables working fine up to a point when I call a new file and then all my session variables are lost.  I have tried everything, but cannot keep them alive when I get into this or any other new file.

I display a form, get user data submitted, then display a next form and after the user submits this next form all the session variables are lost.

Anyone have any idea what is killing my session variables?

Thanks in advance.

I am finally making the upgrade from PHP 5.3 to PHP 7.3.  When converting over the code I noticed that session some sessions are not being processed.  My test code for this is below:

 

session_start(); 
include ("../includes/connect.inc");

echo "hiiiiiiii: ".$currentDate;
echo "He  ".$_SESSION['user'];


if (isset($_SESSION['user']))
{
	$user = $_SESSION['user'];
	$currentDate = date("Y/m/d");

}
else
{
	echo "Session not started: ";
}

 

My include is listed below:

$link = mysqli_connect('localhost', 'root', ''); 
if (!$link) { 
    die('Could not connect: ' . mysql_error("Connection error message")); 
} 
mysqli_select_db($link, 'dbname') or die (mysqli_error($link)); 



date_default_timezone_set('America/Chicago');

define ("TZ_CORRECTION", 43200);

$bkcolor = "#FFFFFF";

$currentDate = (Date("Y-m-d"));

I am not getting the message "Session not started or the current date from the include".   

If it matters I am using WAMP as my testing server

Any help is greatly appreciated.

I have some difficulty identifying why the session variables' values have disappeared in my PHP code.  When I try to echo their values, nothing shows up and when I try to compare the values, it does not work.   There are no error messages to indicate something has gone wrong?   Can someone assist?

I am having probelm in saving Session variables ALthough I'm writing session_start();
in the header of my php script and saving the values of Session array in the next page. It does not print the values or show right results.

Code: [Select]
session_start();
require_once ("functions.php");

$token=$_GET['t'];
if(!isset($token)){
 
$name = stripslashes($_POST['username']);
$email = stripslashes($_POST['email']);

check_validate_input($name, $email);
}
if($token=='register')
{
show_registration_form();
}
  $my_model = new model();
  $arr_info = $my_model->check_members($name,$email);
 
   if (($arr_info==NULL)&&($token!='register'))
    {   
    echo '<p> Hello Guest</p><br />';
       show_mailing_form();
    }
   
  else if (($arr_info['role']=='user')||($arr_info['role'] == 'admin'))
    {
         $_SESSION['userId']=$arr_info['id'];
         $_SESSION['user_role']=$arr_info['role'];
         $_SESSION['user_name']=$arr_info['name'];
        print_r  ($_SESSION);}
here it does not print session array.

Hi,

Also can I use session_start() more than once in a single php file?

My logout file is :

   session_destroy();
   header("location:index.php");
   exit();
?>

About to pull my hair out.  Looks simple, I think it's simple, but something is not behaving.  I have a simple login page (loginpage.php) which checks a database for the FamilyID and Password, if it is a match, then it redirects them to userspage.php.  I eventually want to use the FamilyID as a filter for my database so I only show the stuff relative to that FamilyID.  Using CS5 and the built in functions, and it looks to me that the session variable 'MM_Username' should contain the FamilyID which is "adminid" in my database.  It appears to work since it sends me to my userspage.php when I enter a valid FamilyID and Password, but it will not show me my session variable on the that page!!! PLEASE PLEASE HELP...Slap me in the face if it's a stupid question, but I have spent WAY too much time trying to figure what is wrong.  I have included my code:

 

CODE FOR LOGINPAGE.PHP

 

<?php require_once('Connections/MyTest.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  }

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;   
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }

}
