PHP - Is This The Correct Way To Set A Session?
I am having problems with this code sometimes it works other times it doesnt I cant figure out why.
<?php session_start(); $xml = simplexml_load_file("xmlmonstor/skeleton.xml"); //get the hp, if it exists if (!isset($_SESSION['player_hp'])) { $player_hp = 30; } else { $player_hp = $_SESSION['player_hp']; } if (!isset($_SESSION['mob_hp'])) { $mob_hp = $xml->mob_hp; } else { $mob_hp = $_SESSION['mob_hp']; } // Set amount of starting turns if (!isset($_SESSION['turns'])) { $turns = 500; } else { $turns = $_SESSION['turns']; } $first = mt_rand(1,100); //find out who goes first if ($first < 60) { $player_damage = 5; $mob_hp -= $player_damage; } else { $mob_attack = $xml->attack; $player_hp -= $mob_attack; } if ($player_hp <= 0) { header("Location:south.php?p=defeat"); $turns = $turns - 1; $_SESSION['turns'] = $turns; exit(); } if($mob_hp <= 0) { header("Location:south.php?p=victory"); $turns = $turns - 1; $_SESSION['turns'] = $turns; exit(); } //Gotta store them back in sessions $_SESSION['player_hp'] = $player_hp; $_SESSION['mob_hp'] = $mob_hp; $_SESSION['turns'] = $turns; ?> Am I setting the sessions right or is there a better way to do it? Thanks Similar TutorialsIn Firefox and Google Crome my code works correct, but in IE it doesnt. The problem is that before or after loading a page in IE, $_SESSION is unsetted. If i set $_SESSION['online'] = 1, then after reloading the page then print_r($_SESSION) outputs nothing. It's pretty simple to see what I am trying to do here. For some reason all results in the table are the same exact cityName replacing all existing records. The echoed results are correct. I've include a small dump of my table as well. $query = "SELECT cityName FROM sys_city_dev_2"; $resource = mysqli_query($cxn, $query) or die("MySQL error: " . mysqli_error($cxn) . "<hr>\nQuery: $query"); while($result = mysqli_fetch_assoc($resource)) { $nox = $result['cityName']; $toUpper = ucfirst($nox); echo "$toUpper" . "<br />"; $setString = "UPDATE sys_city_dev_2 SET cityName = '" . $toUpper ."' WHERE cityName != ''"; mysqli_query($cxn,$setString); } 100 Records of table dump (pre running my script above): -- -- Table structure for table `sys_city_dev_2_backup` -- CREATE TABLE IF NOT EXISTS `sys_city_dev_2_backup` ( `ID` int(11) NOT NULL AUTO_INCREMENT, `Mid` int(11) NOT NULL DEFAULT '0', `cityName` varchar(30) NOT NULL DEFAULT '', `forder` int(4) NOT NULL DEFAULT '0', `disdplay` int(4) NOT NULL DEFAULT '0', `cid` int(11) NOT NULL DEFAULT '0', PRIMARY KEY (`ID`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=113970 ; -- -- Dumping data for table `sys_city_dev_2_backup` -- INSERT INTO `sys_city_dev_2_backup` (`ID`, `Mid`, `cityName`, `forder`, `disdplay`, `cid`) VALUES (84010, 1, 'dothan', 0, 0, 0), (84011, 1, 'alabaster', 0, 0, 0), (84012, 1, 'birmingham', 0, 0, 0), (84013, 2, 'flagstaff', 0, 0, 0), (84014, 1, 'auburn', 0, 0, 0), (84015, 1, 'florence', 0, 0, 0), (84016, 1, 'gadsden', 0, 0, 0), (84017, 1, 'huntsville', 0, 0, 0), (84018, 1, 'mobile', 0, 0, 0), (84019, 1, 'montgomery', 0, 0, 0), (84020, 1, 'tuscaloosa', 0, 0, 0), (84021, 2, 'mohave valley', 0, 0, 0), (84022, 2, 'phoenix', 0, 0, 0), (84023, 2, 'prescott', 0, 0, 0), (84024, 2, 'sierra vista', 0, 0, 0), (84025, 2, 'tucson', 0, 0, 0), (84026, 2, 'yuma', 0, 0, 0), (84027, 3, 'bakersfield', 0, 0, 0), (84028, 3, 'chico', 0, 0, 0), (84029, 3, 'fresno / madera', 0, 0, 0), (84030, 3, 'gold country', 0, 0, 0), (84031, 3, 'humboldt county', 0, 0, 0), (84032, 3, 'imperial', 0, 0, 0), (84033, 3, 'inland empire', 0, 0, 0), (84034, 3, 'los angeles', 0, 0, 0), (84035, 3, 'alhambra', 0, 0, 0), (84036, 3, 'merced', 0, 0, 0), (84037, 49, 'fayetteville', 0, 0, 0), (84038, 49, 'fort smith', 0, 0, 0), (84039, 49, 'jonesboro', 0, 0, 0), (84040, 49, 'little rock', 0, 0, 0), (84041, 49, 'arkadelphia', 0, 0, 0), (84042, 49, 'texarkana', 0, 0, 0), (84043, 3, 'modesto', 0, 0, 0), (84044, 3, 'alta sierra', 0, 0, 0), (84045, 3, 'alpine', 0, 0, 0), (84046, 3, 'pedley', 0, 0, 0), (84047, 3, 'redding', 0, 0, 0), (84048, 3, 'alondra park', 0, 0, 0), (84049, 3, 'sacramento', 0, 0, 0), (84050, 4, 'canon city', 0, 0, 0), (84051, 3, 'san luis obispo', 0, 0, 0), (84052, 3, 'santa barbara', 0, 0, 0), (84053, 3, 'stockton', 0, 0, 0), (84054, 3, 'aliso viejo', 0, 0, 0), (84055, 3, 'visalia', 0, 0, 0), (84056, 3, 'yuba city', 0, 0, 0), (84057, 4, 'boulder', 0, 0, 0), (84058, 4, 'colorado springs', 0, 0, 0), (84059, 4, 'denver', 0, 0, 0), (84060, 4, 'applewood', 0, 0, 0), (84061, 4, 'pueblo', 0, 0, 0), (84062, 4, 'air force academy', 0, 0, 0), (84063, 5, 'avon', 0, 0, 0), (84064, 5, 'hartford', 0, 0, 0), (84065, 5, 'new haven', 0, 0, 0), (84066, 5, 'ansonia', 0, 0, 0), (84067, 5, 'fairfield', 0, 0, 0), (84068, 7, 'daytona beach', 0, 0, 0), (84069, 7, 'sebastian', 0, 0, 0), (84070, 5, 'wallingford center', 0, 0, 0), (84071, 8, 'belvedere park', 0, 0, 0), (84072, 7, 'sarasota springs', 0, 0, 0), (84073, 7, 'sandalfoot cove', 0, 0, 0), (84074, 7, 'san carlos park', 0, 0, 0), (84075, 7, 'st. augustine', 0, 0, 0), (84076, 7, 'tallahassee', 0, 0, 0), (84077, 7, 'safety harbor', 0, 0, 0), (84078, 7, 'ruskin', 0, 0, 0), (84079, 8, 'athens-clarke county', 0, 0, 0), (84080, 8, 'atlanta', 0, 0, 0), (84081, 8, 'augusta-richmond county', 0, 0, 0), (84082, 8, 'brunswick', 0, 0, 0), (84083, 8, 'columbus', 0, 0, 0), (84084, 8, 'americus', 0, 0, 0), (84085, 8, 'acworth', 0, 0, 0), (84086, 8, 'valdosta', 0, 0, 0), (84087, 10, 'boise', 0, 0, 0), (84088, 10, 'ammon', 0, 0, 0), (84089, 10, 'moscow', 0, 0, 0), (84090, 10, 'blackfoot', 0, 0, 0), (84091, 10, 'twin falls', 0, 0, 0), (84092, 10, 'meridian', 0, 0, 0), (84093, 10, 'jerome', 0, 0, 0), (84094, 10, 'idaho falls', 0, 0, 0), (84095, 11, 'addison', 0, 0, 0), (84096, 10, 'garden city', 0, 0, 0), (84097, 10, 'eagle', 0, 0, 0), (84098, 10, 'chubbuck', 0, 0, 0), (84099, 10, 'caldwell', 0, 0, 0), (84100, 12, 'bloomington', 0, 0, 0), (84101, 12, 'evansville', 0, 0, 0), (84102, 12, 'fort wayne', 0, 0, 0), (84103, 12, 'indianapolis', 0, 0, 0), (84104, 12, 'muncie / anderson', 0, 0, 0), (84105, 12, 'lafayette / west lafayette', 0, 0, 0), (84106, 12, 'south bend / michiana', 0, 0, 0), (84107, 12, 'terre haute', 0, 0, 0), (84108, 12, 'northwest indiana', 0, 0, 0), (84109, 13, 'ames', 0, 0, 0); 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!

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! 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. 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 $ID; ?>" style="width:680px; height:200px;" noresize="noresize" frameborder="0" border="0" scrolling="Yes" allowtransparency="true" /> </iframe> Evening! I've been iffing and ahhing over this and well im not too sure, hence the post. Code: [Select] // Redirects if there is no session id selected and echos the error on the previous page if(!isset($_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!
Greg

Edited by Maq, 16 May 2014 - 02:18 PM. Hi, Is this the correct way to go by setting cookies for my login 'remember' functionality?, I've posted the relevant login and logout code. Login: <?php session_start(); //some code... if (isset($_POST['remember'])) { $expire = time() + 1728000; // Expire in 20 days $site_domain = 'phpfreaks.com'; //example $_SESSION['username'] = $_POST['username']; //don't worry this has been validated :D $username = $_SESSION['username']; //some sql query to fetch code.. $code = $row['code']; setcookie('username', $username, $expire, NULL, ".$site_domain", NULL, TRUE); setcookie('code', $code, $expire, NULL, ".$site_domain", NULL, TRUE); } ?> Logout: <?php session_start(); if (isset($_COOKIE['username'])) { $expire = time() - 1728000; // Expire in 20 days $site_domain = 'phpfreaks.com'; //example $username = $_SESSION['username']; //some sql query to fetch code.. $code = $row['code']; setcookie('username', $username, $expire, NULL, ".$site_domain", NULL, TRUE); setcookie('code', $code, $expire, NULL, ".$site_domain", NULL, TRUE); } unset($_SESSION['username']); $_SESSION = array(); session_destroy(); ?> Please tell me if it looks good to go and/or any improvements. PS: I want it accessible on all areas of the domain (including subdomains and paths etc.), and HTTP ONLY (so js can't access it) - I believe I've set the right parems? What is the correct way to use the backslash here? I am using an ftp script and retrieving the brand directory name through url. I want to catch it if they try to use \ in the url to list all directories. Code: [Select] elseif($_GET[f]=="\") { echo "You have entered an invalid vendor."; $_SESSION['brand_path'] = "INVALID"; } I have a foreach() that I want to run and I want to check before I test it out if this is even possible or how I would do this correctly if it isn't. I have 3 arrays that all pull data from a database earlier in the script. These three all "match" so that they all belong to the same product, but they are from different queries. I want a foreach() to extract data from all 3 of them and insert that into a database until the arrays run out of data. foreach (($titles_list as $title) && ($prices_list as $price) && ($services_list as $service_id)) { mysql_query("INSERT INTO product_invoices (name, invoice_id, price, quantity, date_time, service_id) VALUES('$title', '$invoice_id', '$price', '$today_slashes', '$service_id')") or die(mysql_error()); } Hopefully you see where I'm going with this. Hi, Im pretty much self taught when it comes to php, never read any books just picked things up as i go, and im looking for some advice on how i build my pages as i believe im not approaching it correctly. Basically i build an index.php, this contains my header, footer, and any menus i may have, then for my content pages, in this case products, contact, about us i use use an include so these content pages just have content. Now by doing this my address bar looks like this index.php?location=contact.php for the sake of google and search results and so on, am i limiting my ability to be found by not using a differant file for each page? should i include a header, footer, menu etc within my content pages rather than the other way around? Thanks in advance for any advice. Hi,
I have upgraded my server from PHP 5.3.3 to version 5.5 and I'm now having a few problems with some code.
This line gives a fatal error of:

It appears this is depreciated? How can I solve this?

Hello all, I'm trying to write a joomla page that will import LinkShare banners into the banner component. The problem I'm having is that LinkShare doesn't seem to always have the correct image size listed. If I use their dimensions, the images come out skewed and bad looking.

Should functions really be used for tasks such as in my example below? I’m attempting to use some for smaller tasks to improve readability and reduce code repetition. Or should they be used for larger tasks?
functions.php
function accessDenied(){
$_SESSION[‘error’] = "You cannot view that page, you wally";
header(‘location: error.php’);
exit;
}
page.php
if(!$loggedin){ accessDenied(); }
Edited by paddy_fields, 12 August 2014 - 08:44 AM. $ error = trim( strip_tags($_GET['error']) ); VS $strip_error = strip_tags($_GET['error']) ; $trim_error = trim($strip_error);Which method is correct way? Also I am first striping and trimming is it wright way. could you please advice me. Thank you Edited by thilakan, 16 October 2014 - 05:50 AM. |
