PHP - Variable Variables Not Working For Session Variable
Hello everyone,
I can get Test 2 to successfully operate the if statement using a variable variable. But when I try the same method using a session variable (Test 1) the if statement is not executed. Please could you tell me why the if statement in Test 1 is not being executed? Code: [Select] <?php # TEST 1 $_SESSION[test_variable] = "abcd"; $session_variable_name = "_SESSION[test_variable]"; if ($$session_variable_name == "abcd") { echo "<br>line 373, abcd<br>"; } # TEST 2 $test_variable = "efgh"; $test_variable_name = "test_variable"; if ($$test_variable_name == "efgh") { echo "<br>line 379, efgh<br>"; } ?> Many thanks, Stu Similar TutorialsQuestion about variable variables and using session variables for them. O.K. So if I have: $foo = 3; $_SESSION['bar'] = "foo"; $$_SESSION['bar'] should equal the value of $foo, however I can't get it to work. Can someone tell me what I am doing wrong..... is it formatting??? Thanks, Thomas i have Created a Session with this code $_SESSION['USER_NAME'] = trim($_POST['username']) How can i access the $_SESSION['USER_NAME'] in other Pages ; and will this code for $var = $_SESSION[USER_NAME] can i get the SESSIOn value in " $var" variable ?? 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'] = $name; // Store session data ?> hi guys. i am trying to set a variable to the session global variable. I've initialized the session with session_start(); at the very beginning of my website, and then i try finding if a session variable has been set like so if(isset($_SESSION['user'])) { print 'user is logged in'; } but this works in reverse. i have not set any session variables, but asking if it is set, results in an affirmative answer. so i am thinking this is because of register_globals. because i went to read about register_globals, and it says that if register_globals is turned off, i cannot use any other varibale except members of the session array. i dont know what that is yet, but a question befo in the php manual it says register_globals is deprecated, and it appears i need to enable it to set other variables as session variables besides it's associative array. if this is true, how to enable register_globals and allow other variables to be used as session variables? My login script stores the user's login name as $_SESSION[ 'name'] on login. For some unapparent reason, i'm getting errors stating that $user and $priv are undefined variables, though I've attempted to define $user as being equal to $_SESSION['name'], using $user to look up the the user's privilege level (stored as the su column ) in the SQL table, and then where the result of the sql query is $priv which is then evaluated in an if statement. I can't seem to figure out why this might not be working. The code I'm using:
<?php
session_start();
function verify() {
//verify that the user is logged in via the login page. Session_start has already been called.
if (!isset($_SESSION['loggedin'])) {
header('Location: /index.html');
exit;
}
//if user is logged in, we then lookup necessary privleges. $_SESSION['name'] was written with the login name upon login. Privleges // are written in db as a single-digit integer of of 0 for users, 1 for administrators, and 2 for special users.
$user === $_SESSION['name'];
//Connect to Databse
$link = mysqli_connect("127.0.0.1", "database user", "password", "database");
if (!$link) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
//SQL Statement to lookup privlege information.
if ($result = mysqli_query($link, "SELECT su FROM accounts WHERE username = $user", MYSQLI_STORE_RESULT)) {
//LOOP TO CYCLE THROUGH SQL RESULTS AND STORE Privlege information as vairable $priv.
while ($row = $result->fetch_assoc()) {
$priv === $row["su"];
}
}
// close SQL connection.
mysqli_close($link);
// Verify privleges and take action. Only a privlege of "1" is allowed to view this page. A privlege of "2" indicates special
//accounts used in other scripts that have certain indermediate additional functions, but are not trusted administrators.
if ($priv !== 1) {
echo $_SESSION['name'];
echo "you have privlege level of $priv";
echo "<br>";
echo 'Your account does not have the privleges necessary to view this page';
exit;
}
}
verify();
?>
I have a script that adds points together based upon the placing. This is the actual script: Code: [Select] <? $points = 0; if($place === '1st') {$points = $points + 50;} elseif($place === '2nd') {$points = $points + 45;} elseif($place === '3rd') {$points = $points + 40;} elseif($place === '4th') {$points = $points + 35;} elseif($place === '5th') {$points = $points + 30;} elseif($place === '6th') {$points = $points + 25;} elseif($place === '7th') {$points = $points + 20;} elseif($place === '8th') {$points = $points + 10;} elseif($place === '9th') {$points = $points + 10;} elseif($place === '10th') {$points = $points + 10;} elseif($place === 'CH') {$points = $points + 50;} elseif($place === 'RCH') {$points = $points + 40;} elseif($place === 'TT') {$points = $points + 30;} elseif($place === 'T5') {$points = $points + 30;} elseif($place === 'Champion') {$points = $points + 50;} elseif($place === 'Reserve Champion') {$points = $points + 40;} echo "Total HF Points: $points"; ?>What it *should* do (my friend's script works the same way and it works) it starts at points = 0, than if there is a first place, it adds 50, and so forth until it reaches the end. It is included into a file, in this area: Code: [Select] <div class="tabbertab"> <h2>Records</h2> <? $query92 = "SELECT * FROM THISTABLE WHERE VARIABLE='$id' OR VARIABLE = '$name' ORDER BY ABS(VARIABLE), VARIABLE"; $result92 = mysql_query($query92) or die (mysql_error()); echo "<table class='record'> <tr><th>Show</th> <th>Class</th> <th>Place</th></tr> "; while($row92 = mysql_fetch_array($result92)) { $class = $row92['class']; $place = $row92['place']; $entries = $row92['entries']; $race = $row92['show']; $purse = number_format($row92['purse'],2); echo "<tr><td>$race</td> <td>$class</td> <td>$place</td></tr>"; } ?> <tr><td colspan='3'><div align='right'><? include('includes/points.php'); ?></div></td></tr> </table> </div> This is the code that is relevant. When ended here, it echoes the last place that appears in the results (such as a 5th place echoing 30 points). When I move it to be included in the while loop, it shows Total Points: 50 Total Points: 25 Total Points: 10 (depending on the results displayed on that page). What am I doing wrong? I have a session variable that will be set to a number called... Code: [Select] $_SESSION['number'] I have page where I want to set a variable in the format of $serv# (with "#" being the value of the session variable). Is there a way to write one simple line of code that in effect says... Code: [Select] $serv . $_SESSION['number'] = "selected='selected'"; I'm just looking to avoid having to write this code... Code: [Select] if ($_SESSION['number'] == 1) { $serv1 = "selected='selected'"; } elseif ($_SESSION['number'] == 2) { $serv2 = "selected='selected'"; } etc etc It's basically putting a variable inside of a variable and I'm not sure if this is allowed/proper? Any insight would be appreciated. Thanks, Gary does anyone know how to decode this XML variable value into string values? I also need to know the oposite way: creating variable values into xml. I've tried several code examples but they did filter the requested data.

I've been working on this for days now, and I just can't find the solution. I just wondered whether someoen could perhaps have a look at this and let me know where I'm going wrong. Many thanks and regards Need help declaring some session variable guys. I have a login form where the member enters his 1. Pilot Callsign 2. Password I want to declare that Pilot Callsign as the session variable on authentication. Using that Pilot Callsign session variable, I will fetch data from the database relevant to his profile. I already have the whole login page coded along with the restricted access pages (not coded by me). Check this out 1. Page is coded like this and working PERFECTLY --- Code: [Select] <?php // *** Validate request to login to this site. if (!isset($_SESSION)) { session_start(); } $loginFormAction = $_SERVER['PHP_SELF']; if (isset($_GET['accesscheck'])) { $_SESSION['PrevUrl'] = $_GET['accesscheck']; } if (isset($_POST['pilot_callsign'])) { $loginUsername=$_POST['pilot_callsign']; $password=$_POST['password']; mysql_select_db($database_brn_system, $brn_system); $LoginRS__query=sprintf("SELECT pilot_callsign, password, staff_level, firstname FROM pilots WHERE activated = 1 AND pilot_callsign=%s AND password=%s", GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text")); $LoginRS = mysql_query($LoginRS__query, $brn_system) or die(mysql_error()); $loginFoundUser = mysql_num_rows($LoginRS); if ($loginFoundUser) { $loginStrGroup = mysql_result($LoginRS,0,'staff_level'); if (PHP_VERSION >= 5.1) {session_regenerate_id(true);} else {session_regenerate_id();} //declare two session variables and assign them $_SESSION['MM_Username'] = $loginUsername; $_SESSION['MM_UserGroup'] = $loginStrGroup; ?> --- 2. As you can see, there already is a session variable declared for Pilot Callsign But on the next page "Restricted Access Page", when I try to call this same Session Variable, it doesn't work. I tried doing this <?php echo $_SESSION['MM_Username'] ?> Moreover, I even tried to fetch data from the table like this - SELECT * FROM pilots WHERE pilot_callsign=$_SESSION['MM_Username'] Doesn't work hi all , i am working on a script which is oop driven and i m not much familiar with it, i appericiate if someone can help me to solve this problem , so basicaly current script is only setting one session variable to true if user login $_SESSION['is_successful_login'] , here is my code <?php include('files/db.php'); class ajaxLoginModule { private $timeout = null; private $target_element = null; private $wait_text = null; private $form_element = null; private $wait_element = null; private $notify_element = null; function __construct() { include ('config.php'); $msql = new Db; $msql->connect(); $this->is_login(); } function get_config() { $this->set_ajax_config(); } function set_ajax_config() { $this->timeout = AJAX_TIMEOUT; $this->target_element = AJAX_TARGET_ELEMENT; $this->wait_text = AJAX_WAIT_TEXT; $this->wait_element = AJAX_WAIT_ELEMENT; $this->notify_element = AJAX_NOTIFY_ELEMENT; $this->form_element = AJAX_FORM_ELEMENT; } function initLogin($arg = array()) { $this->get_config(); $this->login_script(); } function initJquery() { return "<script type='text/javascript' src='files/jquery-1.3.2.min.js'></script>"; } function login_script() { include ('files/login_script.php'); } function is_login() { if(isset($_POST['username'])) { $username = $_POST['username']; $password = $_POST['password']; $strSQL = "SELECT * FROM ".USERS_TABLE_NAME."

Thanks Hi everyone, I am trying to implement an OAuth system in PHP. I've got the code working but the very first time a fresh, new browser window is opened, the code doesn't work. If I refresh the page and try again, then it works. I have a few suspicions as to where the problem might be but other than that I am stumped. I have two classes: OAuthServer and OAuthClient. I create and store an object of the appropriate class in session variables. I know this is tricky but I am serializing and unserializing properly. To fetch responses from the Server, I am using curl. As curl uses a different session from the browser, I am doing a session_write_close before initializing curl and passing the appropriate parameters to curl. But my code needed to further write session variables even after session_write_close was called and to achieve this, I am calling session_start(), once again, after the curl code is finished. I found that this works but PHP was throwing warnings saying that the header info had already been sent or something like that, but I have suppressed such warnings. I suspect the error has something to do with this but I'm not sure. The part that doesn't work the very first time is that on the server-side, the session variable that is supposed to contain the OAuthServer object is NULL. But if I do a refresh of the page(flow: login_page->error_page), it works. Can anyone tell me why I am encountering the above error and if I am doing things correctly or not. Any help would be greatly appreciated. Thanks & Regards, GarbageGigo The first page is used to submit data to second page (and also show errors if there are any with the data submitted). The second page should be retrieving the posted data and assigning that data to session should it need to refresh back to the first page to show errors. The session data is used to repopulate the form. Right now I'm typing test into the review_name variable and when the page redirects back to the form to display the error messages, that field is not populated with "test".

Going to get coffee and some fresh eyes. Cheers Hi all - hoping somebody can see this clearer than me... Goal: to create a very simple shopping cart page that receives $_POST info and stores it as an array in a session variable so items will be displayed in cart on clients return to shopping cart page. Problem: I can get the array to display the first item that I add to the shopping cart but each susequest item just overwrites the first because it is using the same session variable name. How do I store the next product info in a DIFFERENT session variable and display it on the shopping cart page without writing over the first? I have two pages with products on them which need to submit orders to the shopping cart page. They use a simple form with these fields: <form method="post" action="cartaction.php"> <p> <input type="submit" name="submit" value="Buy" /> <input type="hidden" name="cartaction" value="add" /> <input type="hidden" name="item" value="coppercasserole" /> </p> </form> This is what I have so far on the cartaction page which can display the first product added to the cart: <?php //If form is submitted, call the function and save all data into the array $_SESSION['form'] if($_POST['submit'] == "Buy"){ setSessionVars(); } function setSessionVars() { if ( !isset($_SESSION['cart']) ) $_SESSION['cart'] = array(); $item = array(); foreach($_POST as $fieldname => $fieldvalue) { $item[$fieldname] = $fieldvalue; } $_SESSION['cart'] = $item; echo "<table> <tr> <td>" .'<img src="images/'.$item['item'].'.jpg"' . "<td/> <td>" . $item['item'] . "</td> <td>" . '<input type="text(30)" name="value" value="1" /> <input type="submit" name="puchasednum" value="Update This One Item" />' . "</td> </tr> </table>"; } ?> I am new to PHP and have hit a brick wall as to how to display each product array as a new session variable in the shopping cart. I would like to keep it as simple as possible as I am getting easily confused! Is there a way that I can increment the session variable with something like this: <?php //session counter $counter = count($_SESSION['cart']); if (($_POST['name'] !="")){ $counter = $counter + 1; $_SESSION['cart'][$counter] = array(); } ?> Or can I pass a field as a product ID and use this somehow to create a new session variable for each product or clear the post variables somehow? Any help would be much appreciated? Thanks I'm using Session variables for the first time on a site I'm developing. I had it working fine while I was doing some admin and testing in subfolders. But the problem is I'm losing the session variables when I load the page from www.example.com, but it works from www.example.com/index.php. I would be happy to post some code if needed. hi there, i'm trying to put a message in the footer of a page which welcomes a person who is logged in with his/her name, using sessions of course; when i place this: Code: [Select] $username = $_SESSION['valid_user']; in the footer before the echo: Code: [Select] echo "You are logged in as $username"; but the session is also needed before the footer to use the username for other things , such as -checking his credit- so if place in footer the footer shows name in browser but checking credit would not happen as the assignment is at the buttom. IF i place the assignment above at the top of the file: everything works for the user and checking credit ..etc...but the footer is not there... cud not put this any clearer..sorry...hope if someone cud help...thanks Is it good practice to put an oop object in session variable |
