Staying Logged In	View Content

Hi guys,

Im building a website for a company http://www.eminence-logistics.co.uk and the client wants a log in system which im having problems with. The registration system is all working fine.

If you go to the website you can see where the login form is.

Now when the user isn't logged in i need the form to show, but when the user IS logged in i would like a message replacing the form saying welcome, along with a log out button.

How do i do this?

Thankyou very much

Hi. I'm new to php. I created a register, log in, welcome, and log out page for my site. They are all working accordingly. I'm having one problem that I can't seem to fix. I would like to stay logged in as I navigate other pages of my site. Everytime i click on a link to another page within my site I get logged out. I know this issue might pertain to using session but thats all I was able to find using google search. Can anyone help? Much appreciated.

Looking to INSERT a row in a data table and keeping the User on the current page.

Will it work like what I have below, or do I need to send it to its own page then return the User back to where he started?

What I have below isn't inserting a row. No errors showing.

function bookmark_add () {

if (isset($_POST['submit'])) {

include("/home2/csi/public_html/resources/con.php");


	$query = "INSERT INTO a_player_bookmark (bookmark)
				VALUES ('1')";
	
	$results = mysqli_query($con,$query);
	echo mysqli_error($con);


}

	$output = '<form name="bookmark_add" method="post" action="" class="bookmark-plus">';
    $output .= '<span><input type="submit" name="Bookmark"></span>';
	$output .= '</form>';
	
	return $output;

Php Ordering Form Help Please. Variables Staying The Same After Submit

Similar Tutorials

View Content

So I'm making an ordering form for pizza, and it works fine and im using two separate pages: 1- display the form where the user can select the pizza, and 2-display the order and the price, and user can go back and edit

the problem im having is when i got back from the 2nd page to the 1st page, to edit the data, I want the variables to stay the same. For example, if the user selected a medium cheese pizza, i want the values of cheese and pizza to still be there, so the user doesnt have to fill the entire form out again.

ive done this before, but now when i try it doesn''t work and Ive tried everything. Thanks in advance

If the code is needed, I'll post it here

Alright, so I'm fairly new to PHP coding and I still have a ton to learn, so it's not surprising that I ran into a problem pretty quickly.
I've setup a database and even managed to scrap together a SIMPLE member management system. All of it works, but I still need one thing. A lot of sites I visit which allow users to signup have this at the top; Login or Register. Nothing huge, just in the corner, know what I mean? I was wondering how I do this? Also, after someone logs in, how do I change that to show "You are logged in as [username] and then a logout option?

Logged On User

Hello all,

This has probably been asked before but I couldn't find through search.

And I'm pretty sure is not possible, but...

Is there a way of displaying the windows logged on user?
or
get the name of the compter? as I know I can get the ip address.

The reason I ask.
Each user has their own network account but on occasion we need to log on a user as a generic account we have. And I want to check if it's this user accessing the page so different options etc can be displayed.
I could use the computer name to check this as we log all activity. I could then query the log using the comp name to find logged on user.
Unfortunately the log does not hold ip, which would seem obvious but it doesn't

Many Thanks

How To Check If Already Logged In

Hi guys,

Have a wierd scenario where my brain is simply refusing to think.

I have small script which let's a user log in through a login screen. Thats ok.
I can check whether the user is already logged in the same machine through sessions.

My requirement is :
I need to restrict the same username logging in from multiple computers at any one given time.
In other words, a user can not use two machines to login at the same time.

Can someone please suggest a method to solve this scenario.
Your help is very much appreciated.

Cheers

Best Way To Check If User Is Logged In

Similar Tutorials

Hi there, I've been searching the internet for the best way to check if the user has been logged in. Some codes have security breaches. So I'm not sure where to start. Here's what I've come up with: The user logs in and is checked whether he/she is a valid user, if not return false and if true carry on and create session, I read the post that Jacques1 made about session feedback and implemented what he said. After that the session variables are assigned and then the user id, session_id and a unique identifier to check against on each page load are inserted into a database and then the user is logged in. Here's my code: (please note this is in a class and only shows the login function)

function Login($username, $password)
	{
		try
		{

How To Show Logged On Users?

Sites such as this one often show the logged on users and guests. I have no reason to need to do so, but am curious on how this is accomplished. For users, yes, you've authenticated them and logged them on regardless of IP address, but how do you know they didn't just close their browser? For guests, are they just using IP address? And still, how do you know when they leave? PS. How should I include an image in a post like I did? What I did was first attach a file, and then edit the post to include that file as an image. Couldn't seem to include an image off my local PC. Not a better way? Attached Files Capture.PNG 4.13KB 0 downloads

Php Only Works When I’m Logged Into Wordpress.

Hi all,

My company has a php site on wordpress that i’m trying to add google AD tracking to.
There is a single header.php file for all pages so i’ve added a little piece of php to check what the current page is and to write out the appropriate event trigger.

Now, on the live site, when i’m logged into word-press and run the page, I can see the triggers firing fine on Tag assistant, if i un-comment the alerts, they also fire.

When i log out of word-press and hit the page, nothing happens at all. No alerts, no google triggers, nothing in the php is running?

Any ideas whats going on ?

<script> window.dataLayer = window.dataLayer || []; function gtag(){dataLayer.push(arguments);} gtag('js', new Date()); gtag('config', 'AW-1234567897'); <?php $url = $_SERVER['REQUEST_URI']; if ($url =="/thankyou/") { print " gtag('event', 'conversion', {'send_to': 'AW-1234567897/1234567897', 'value': 1.0, 'currency': 'GBP' }); "; print " gtag('event', 'conversion', {'send_to': 'AW-1234567897/1234567897'}); "; //Print "alert('OK');"; //Print "alert('" . $url . "');"; } ?> </script>

Detect If Logged In For One User??

View Content

In the site I am making, the client wants one account for everyone (don't ask me why, it's a long, silly reason) And I'm wondering how I would configure mySQL to deal with that (I asked this in the mySQL area) and in PHP (For you guys ) what would I need to put in order for this to work. I'm very new with PHP and mySQL, so please forgive the nooby question.

*EDIT* the admins have their own username and psw for adding, deleting, and editing articles. and that works. But all users that register will have this set user and psw displayed to them. I want to make it so they have to log in to see an article.

Keeping Users Logged In

Similar Tutorials

View Content

What are the different ways you can keep a User "logged in"?

From what I *vaguely* recall from a year or two ago when I read a whole hoard of PHP books, you commonly use cookies and sessions.

But I'm asking this more from an OOP standpoint than a PHP standpoint.

Let's say I have a User record in my database, and a User comes along and attempts to log in.

In OOP terms, I would think you'd call some class to help log them in, and upon successfully logging in, you would "load" the User object into memory and set the "LoggedIn" field to "True". Then as long as that field was set in their object, they could surf all over the place and do things like change their account and buy things.

Is that how you would do it in OOP?

Login script:
This script does the following:

Checks that the user is NOT already logged in - if they are they
are redirected to the members page by the 'checkLoggedIn()' function.

Checks if the login form has been submitted - if so, the 'login' and
'password' fields are checked to ensure they are of the correct format and length.
If there are any problems here an error is added to the $messages array and
then the script executes the 'doIndex()' function - this function basically
outputs the main 'index' page for this script - ie the login form.

If there are no problems with the previous step, the 'login' and 'password'
field data is passed to the 'checkPass' function to check that an entry
exists in the 'users' table for that login/password pair.
If nothing is returned from the 'checkPass()' function, an error is
added to the $messages array and the 'doIndex()' function is called as above.

If a row of data is returned from the 'users' table, the data is passed to
the 'cleanMemberSession()' function - which initializes session variables and
logs the user in.  The user is then forwarded to the members page.

If the form hasn't yet been submitted, then the 'doIndex()' function is called
and the login page is displayed.
*/

checkLoggedIn("no");

// Page title:

// password must be between 4 and 15 chars - any characters can be used:
field_validator("rsPass", $_POST["rsPass"], "string", 4, 15);

// if there are $messages, errors were found in validating form data
// show the index page (where the messages will be displayed):
if($messages){
doIndex();
// note we have to explicity 'exit' from the script, otherwise
// the lines below will be processed:
exit;
}

// OK if we got this far the form field data was of the right format;
// now check the user/pass pair match those stored in the db:
/*
If checkPass() is successful (ie the login and password are ok),
then $row contains an array of data containing the login name and
password of the user.
If checkPass() is unsuccessful however, $row will simply contain
the value 'false' - and so in that case an error message is

$email = mysql_real_escape_string($_COOKIE['uemail']); //Get username stored in cookie
$pp = mysql_real_escape_string($_COOKIE['pp']);
if ($pp == 1){
$sessionid = mysql_real_escape_string($_COOKIE['sessionid']); //Get user's session ID
$check = mysql_query("SELECT * FROM `users` WHERE `email` = '$email' AND `session_id` = '$sessionid' AND `login_ip` = '$ip' AND `pp` = '1' ") or die(mysql_error()); //Check if all information provided from the user is valid by checking in the DB
$answer = mysql_num_rows($check); //Return number of results found. Equal to 0 if not logged in or 1 if logged in.
if ($answer == 0 || $sessionid == '') { //Check if login is valid. If not redirect user to login page
header('Location: ulogin.php');
