From the link: "session.cookie_lifetime specifies the lifetime of the cookie in seconds which is sent to the browser. The value 0 means "until the browser is closed." Defaults to 0.". It doesn't state anything about "session stays active even after the browser has been closed"

Ok, thanks for the quick answer. If I don't want to use cookies, can I instead place the file temporarily in a database (mysql?) and have like a timeout that removes and updates the database? Is this more optimized than cookies?

Yes, I am. Is this the wrong way to use it? (correction: how do I make it work? )

Hi! I'm working on a simple e-commerce script. I have some $_SESSION variables that is defined and works fine while surfing on the site. But when I close the browser and reenter the site, all the session-variables are not defined (unset?), until i click on a link on the site. Weird behavior... please help! /I

Solved this with: if(detect_ie()){ // Converts the input to UTF-8 $q=utf8_encode($q); } $q is the input string. And detect_ie checks if it's IE.

I identified the problem and it seems that the string you type in the input field is in ISO-8859-1. I tested to type in: "Mangold SG Hävstångscertifikat Sverige Select - (5 år)" and got a hit. This problem only occurs in Internet Explorer.

I don't know if this is a specific ajax problem or if it's just Internet Explorer. I'm working on an ajax live search function ( i followed the guide here http://www.w3schools.com/php/php_ajax_livesearch.asp). I'm converting an excel-file to XML. When I fill in the form with the letters å, ä, ö (Swedish) in internet explorer I get no hits. In any other browsers it works fine. I have defined UTF-8 in all the browsers, tested ISO-8859-1 (recommended Swedish) and even tried combining them. Nothing works... Any ideas?

Haha, oh sorry. What I meant was that "false" didn't gave any value while "true" gave "1" (I tested debugging with die()). What is the problem?

Ok, I changed the code a little bit. while I was debugging, I noticed that $_SESSION['logged_in'] = false; doesn't show anything while $_SESSION['logged_in'] = true shows "1". if($_SESSION['password'] != $pass) {... //does work <?php include("structure.php"); include("session.php"); global $session; ?> <!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Strict//EN' 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd'> <html xmlns='http://www.w3.org/1999/xhtml'> <head> <meta http-equiv='Content-Type' content='text/html; charset=utf-8' /> <link rel='stylesheet' href='http://mindu.mine.nu/amazing_solutions/gallo_negro/css/style.css' type='text/css' /> <title>Gallo Negro</title> </head> <body> <div id="sitecontainer"> <div id="contentcontainer"> <div id="content"> <div id="center_box"> <?php if ($session->logged_in==false ) { ?> <h1>VÄLKOMMEN ADMINS: LOGGA IN!</h1> <form action="process.php" method="post"/> <input type="password" name="pass" maxlength="30" onBlur="if(this.value=='')this.value='Lösenord123';" onClick="if(this.value=='Lösenord123')this.value='';" value="Lösenord123"/> <input type="submit" value="Logga in" name="sublogin"/> <?php } else{ ?> <p>Inloggad</p> <a href="process.php">Logga ut</a> <?php } ?> </div><!--end of #center_box --> </div><!--end of #content --> </div><!--end of #contentcontainer --> <?php footer();?> </div><!--end of #sitecontainer --> <script type="text/javascript" src="http://jqueryjs.googlecode.com/files/jquery-1.2.6.min.js"></script> <script type="text/javascript" src="safe-ajax.js"></script> </body> </html> <?php include("session.php"); class Process { /* Class constructor */ function Process(Session $session){ /* User submitted password form */ if(isset($_POST['pass'])){ $this->procLogin(); } /* User is directed here because he want's to log out*/ else if($session->logged_in==true){ $this->procLogout(); } /** * Should not get here, which means user is viewing this page * by mistake and is redirected. */ else{ header("Location: google.se"); } } function procLogin(Session $session){ /*Login attempt*/ $retval = $session->login($_POST['pass']); /* Login successful */ if($retval==true){ $session->logged_in=true; header("Location: http://mindu.mine.nu/amazing_solutions/gallo_negro/gallologin.php"); } /* Login failed */ else{ $session->logged_in=false; header("Location: http://mindu.mine.nu/amazing_solutions/gallo_negro/gallologin.php"); } function procLogout(Session $session){ $retval = $session->logout(); header("Location: http://mindu.mine.nu/amazing_solutions/gallo_negro/gallologin.php"); } } } /* Initialize process */ $process = new Process; ?> <?php class Session { var $logged_in; var $password; var $referrer; var $url; //The page url current being viewed /* Class constructor */ function Session(){ $this->startSession(); } function startSession(){ session_start();//Tell PHP to start the session $_SESSION['password'] = "password"; $password=$_SESSION['password']; /* Determine if user is logged in */ //$this->logged_in = $this->checkLogin(); /* Set referrer page */ if(isset($_SESSION['url'])){ $this->referrer = $_SESSION['url']; }else{ $this->referrer = "/"; } /* Set current url */ $this->url = $_SESSION['url'] = $_SERVER['PHP_SELF']; } function login($pass){ /* Password error checking */ if($_SESSION['password'] != $pass) { $_SESSION['logged_in'] = false; return false; } /* password correct, register session variables */ $this->password = $_SESSION['password']; /* Login completed successfully */ $_SESSION['logged_in'] = true; return true; } function logout(){ unset($_SESSION['logged_in']); /* Reflect fact that user has logged out */ $this->logged_in = false; } } $session = new Session; ?>

I have this problem whenever I zoom out in the browser (FF). The div-boxes that is close to the right borders jumps down to the next vertical line. See for yourself: http://mindu.mine.nu/amazing_solutions/gallo_negro/main.php The images on the top, the last link in the menu does just that and the right column in the middle seems to draw closer to the right corner. --- The other problem I have is centering two columns in a div-box. I've managed to center it, but it seems like the wrong way of doing it? div#boxcontainer{ position:absolute; left:50%; margin-left:-460px; margin-top:10px; } div#left_box { float:left; height:700px; width:450px; background-image:url("http://mindu.mine.nu/amazing_solutions/gallo_negro/img/opacity70.png"); background-repeat:repeat; color:#FFF; border:1px solid #3e3e3e; text-align:justify; margin-right:20px; } div#right_box { float:left; height:700px; width:450px; background-image:url("http://mindu.mine.nu/amazing_solutions/gallo_negro/img/opacity70.png"); background-repeat:repeat; color:#FFF; border:1px solid #3e3e3e; }

I've just followed this tutorial on how to make captcha: http://www.webcheatsheet.com/PHP/create_captcha_protection.php --- Here's how it looks like on my page: http://81.226.101.66/projektarbete/benni/TEST/register.php --- Now the problem is, the session variable "$_SESSION["security_code"]" that is created when the image is created in "create_image.php". When I run this file in the browser the variable does update to what is written in the image. When I run the "register.php" the image refreshes, but the variable $_SESSION["security_code"] remains the same. I think that the problem is that the session variable isn't updated because "create_image.php" is never used execept in<img id="imgCaptcha" src="captcha/create_image.php" >, that's only the img and not the code in that file. Please help! --- Here's the code: create_image.php <?php //Start the session so we can store what the security code actually is session_start(); //Set the session to store the security code $_SESSION["security_code"] = $security_code; //Send a generated image to the browser create_image(); exit(); function create_image() { global $security_code; //Let's generate a totally random string using md5 $md5_hash = md5(rand(0,999)); //We don't need a 32 character long string so we trim it down to 5 $security_code = substr($md5_hash, 15, 5); //Set the image width and height $width = 100; $height = 20; //Create the image resource $image = ImageCreate($width, $height); //We are making three colors, white, black and gray $white = ImageColorAllocate($image, 255, 255, 255); $black = ImageColorAllocate($image, 0, 0, 0); $grey = ImageColorAllocate($image, 204, 204, 204); //Make the background black ImageFill($image, 0, 0, $black); //Add randomly generated string in white to the image ImageString($image, 3, 30, 3, $security_code, $white); //Tell the browser what kind of file is come in header("Content-Type: image/jpeg"); //Output the newly created image in jpeg format ImageJpeg($image); //Free up resources ImageDestroy($image); } ?> part of register.php <?php include("include/session.php"); ?> <p>Anti-Spamskydd</p> <p> <img id="imgCaptcha" src="http://mindu.mine.nu/projektarbete/benni/TEST/captcha/create_image.php" > <?php echo $_SESSION["security_code"]; ?> <input id="btnCaptcha" type="button" value="Ladda om" name="btnCaptcha" onclick="getParam(document.frmCaptcha)" /><br/> <input type="text" name="captcha" maxlength="30" value="<?php echo $form->value("captcha"); ?>"><?php echo $form->error("captcha"); ?> </p> <p class="textinput"><input type="hidden" name="subjoin" value="1"><input type="submit" value="Registrera!"></p> </form> part of session.php /* Captcha error checking */ $field = "captcha"; $captcha=$_REQUEST["captcha"]; $sec_code=$_SESSION["security_code"]; if ( ($_REQUEST["captcha"] == $_SESSION["security_code"]) && (!empty($_REQUEST["captcha"]) && !empty($_SESSION["security_code"])) ) { $this->referrer = "http://81.226.101.66/projektarbete/benni/TEST/register.php"; // The captcha code is right, go back to register.php } else{ if(!$subcaptcha || strlen($subcaptcha = trim($subcaptcha)) == 0){ // If the field is empty, display error $form->setError($field, "* skriv in kod $sec_code"); $this->referrer = "http://81.226.101.66/projektarbete/benni/TEST/register.php"; } else{ $form->setError($field, "* Fel kod $captcha , $sec_code "); // Else the captcha is wrong, display error $this->referrer = "http://81.226.101.66/projektarbete/benni/TEST/register.php"; } } ajax_captcha.js //Gets the browser specific XmlHttpRequest Object function getXmlHttpRequestObject() { if (window.XMLHttpRequest) { return new XMLHttpRequest(); //Mozilla, Safari ... } else if (window.ActiveXObject) { return new ActiveXObject("Microsoft.XMLHTTP"); //IE } else { //Display our error message alert("Your browser doesn't support the XmlHttpRequest object."); } } //Our XmlHttpRequest object var receiveReq = getXmlHttpRequestObject(); //Initiate the AJAX request function makeRequest(url, param) { //If our readystate is either not started or finished, initiate a new request if (receiveReq.readyState == 4 || receiveReq.readyState == 0) { //Set up the connection to captcha_test.html.

I've figured out that in Internet Explorer 7 the drop down menu with: div#menu li:hover ul { display:block;} behaves as if : div#menu li:hover ul { display:inline;} --- is there any compatibility fault with display:block?

I've just finished the structure of my site. But my drop-down menus displays and behaves weirdly in Internet Explorer 7. I figured that I can boycott Internet Explorer 6, but not IE7 because many ppl still use the browser (like the 3rd most used). http://mindu.mine.nu/projektarbete/benni/TEST/structure.php Any idea?
