PHP - Terminating An Php Session Without Closing Browser
Hi, i m playing arround with php sessions and just started afew testing on it (i never actually used them so i m discovering something new) and i would like to know how can you terminate an PHP Session without closing your browser. For testing i did this small code, just to see the behavior:
Code: [Select] <?php session_start(); $id = session_id(); echo $id; session_unset(); session_destroy(); ?> The code above seens only to kill the $_SESSION's variables but what i would like is to Kill the PHPSESSID cookie/session cookie. is there anyway you can achive that? thanks in advance Similar Tutorialshey guys, I am trying to setup a session for a filter , I have a button that the user can click on or off, the button starts off but when the user clicks on it a new session starts and it stays on until the user clicks it again to turn it off or when the browser sessions ends... Any help is welcome, thanks guys, you are the best Hello, How do I get a user's session destroyed when he closes his browser? Thanks in advance Hey All, I have a sessions table that is used to see if a user is online. It only gets deleted when they click the Logout button. What I need to do is have it so it gets deleted even if they close the browser. Should I add a column in the sessions table with a time stamp and check on each page for every user to make sure its great than 30 min? Is there a better way to do this, without so many queries? Thanks Hi Guys, I have the following $pattern = '<tr class="newsitem">'; when I echo this out it produces <tr class="newsitem"> </tr> Why is it automatically closing the tag? I dont want this becuase i'm using preg_replace and the tag is closed elsewhere already on the page. I am trying to create an index page which contains registration and login field the problem that i get is on successful login a warning is displayed session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\xampp\htdocs\Eventz.com\index.php:116) in C:\xampp\htdocs\Eventz.com\index.php on line 235 This is the login part of my index.php this tag is inside an html table below the login form I also have a registration form and its php code above the login form Code: [Select] <?php if (isset($_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. Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/s519970/public_html/header.php:27) in /home/s519970/public_html/admin/login.php on line 2 What I can gather is I can't use "header (Location: 'admin.php')" after i've used session_start(). 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, $_SESSION['basic_is_logged_in'] = true; require("main.php"); exit;?> I was curious.. I read that after using a PDO connection you should set the object to null to close it out. In this instance: Code: [Select] function IsOwner($regionid, $user) { global $Username, $SQL_Server, $SQL_User, $SQL_Pass; $pdo = new PDO("mysql:host=$SQL_Server;dbname=$SQL_Database", $SQL_User, $SQL_Pass); $sql = $pdo->prepare("SELECT count(region_id) FROM region_players WHERE region_id = ? AND user_id = ? AND owner = 1"); $sql->execute(array($regionid, $user)); if ($sql->rowCount() == 0) { return false; } else { return true; } $pdo = null; } Since the return is called prior to the nulling, does it leave a connection hanging or does PHP do some sort of auto-closeout when a function ends? Should I instead be doing: Code: [Select] function IsOwner($regionid, $user) { global $Username, $SQL_Server, $SQL_User, $SQL_Pass; $ownerstatus = false; $pdo = new PDO("mysql:host=$SQL_Server;dbname=$SQL_Database", $SQL_User, $SQL_Pass); $sql = $pdo->prepare("SELECT count(region_id) FROM region_players WHERE region_id = ? AND user_id = ? AND owner = 1"); $sql->execute(array($regionid, $user)); if ($sql->rowCount() > 0) $ownerstatus = true; $pdo = null; return $ownerstatus; } ? Hello, I'm working on a page where users can add articles by writing text in textareas with a WYSIWYG editor. When they submit the form it's saved in a database. As a summary of the article i grab the first 800 characters of the article, but as you could imagine there might occur html tags like <div> or <span> in the summary which are not closed. To prevent this from ruining my page layout when their articles are posted on the wegbsite I could use strip_tags but I'd like to keep the format, also this would delete images. I couldn't think of another solution then a function which checks for open tags and if so; add closing tags at the end of the summary. I already made a similar function a while back, but that one only checks for <div> and <span>, as those are the worst.. The nasty part is that I kind of deleted that function accidentally, and I can't fully remember how I wrote that.. So what I would like to have is a function that checks for all unclosed html tags and add the associated closing tags, in the right order, at the end of the summary. Any help getting on the right track is appreciated. Hi, I wonder if there is any simple solution for the following. I have a login script (existing script modified for my site) that pops up in greybox (found at: orangoo.com/labs/GreyBox/). When clicked on Login a function is called which checks if the login is correct an then goes to a page. This is written in PHP. To refer to an page the following code is used => header ("Location: index.php"); This is working but off course the referral page is opened inside the greybox. I would like the greybox to close and the index.php page to reload. You can see what I'm trying on www.mypersonalad.org click "Aanmelden" in the upper left corner. Login: "testing" pass: "test". Please don't hack I have only heard about injection and have no protection for the moment. That's for later. I've tried adding code like this in php => header("Location: index.php onclick=\"parent.parent.GB_hide();\""); But that is not working. My thoughts are that I should check in my login page (the one in greybox) if the user is already logged in. If he is logged in give a message like: "You are now logged in. This page closes automatically in 2 seconds". But I don't know how to do this. Any help please? Hi Have an issue with a script that connects to multiple Access databases to extract data. There is one master database and then numerous small databases (I take no responsibility for the design!). The master is opened and then the sub databases are looped around, opened process and closed in turn. However after about 20 connections I get the error [ODBC Microsoft Access Driver] Too many client tasks for any new connections. It is related to the number of connections rather than the number of operations on databases (ie, if I comment out one of the pieces of SQL run on each database it makes no difference). I am closing the connection and unsetting the variable that stores the connection. As such there shouldn't be an excess of connections open at any one time. Any suggestions? All the best Keith There are no opening and closing tags in the code example of the file PostsController.php in this tutorial:
http://book.cakephp....g/part-two.html
Should I always use opening and closing PHP tags throughout with CakePHP? Hello fellow coders!

It calls a javascript function to submit the form. The javascript function is as follows Code: [Select] function submitform(num) { if (num == 2) { document.myform2.submit(); return 1; } if (num == 3) { document.myform3.submit(); return 1; } if (num == 4) { document.myform4.submit(); return 1; } if (num == 5) { document.myform5.submit(); return 1; } if (num == 6) { document.myform6.submit(); return 1; } else { document.myform.submit(); return 1; } }I can log in though when I go to enter the profile the $_SESSION['user'] is gone and I am logged out. I just can't seem to track down the problem and it is frustrating the heck out of me. If anyone has any ideas PLEASE help! 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. I'm reading over this book and I came across something that looked very odd:
public function DisplayHeader()
{
?>
<table width="100%" cellpadding="12"
cellspacing="0" border="0">
<tr bgcolor ="black">
<td align ="left"><img src = "logo.gif" /></td>
<td>
<h1>TLA Consulting Pty Ltd</h1>
</td>
<td align ="right"><img src = "logo.gif" /></td>
</tr>
</table>
<?php
}
In the function it closes a php tag, uses raw html that is rendered as is on the page, and then returns back to opening the php tag. I understand why it is being done. It is easier to write raw html here than to echo it in a php block, but it just looks odd. Anyone actually use this technique?
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. 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. I'd like to use an application that's not browser based, on Internet Explorer. I've read somewhere that this is possible with a PHP script, but which one? If you can get me on the right track, I'd really appreciate it. Cheers. |
