PHP - Need Help Getting A Login Slider To Disappear When Logged In

This topic has been moved to JavaScript Help.

http://www.phpfreaks.com/forums/index.php?topic=358408.0

When I asked how to make this Log In Form disappear once it performs it's function:

<form action="../login.php" method="post" accept-charset="UTF-8" class="middletext"
onsubmit="javascript:this.style.display='none';">
<p>
<input type="text" size="20" name="user_name_login" id="user_name_login" value="ENTER     USERNAME" style="color:#D9D9D9" style="vertical-align:middle"; onfocus="if     (this.value=='ENTER USERNAME') {this.value=''; this.style.color='#696969';}" >
<input type="text" size="20" name="password_login" id="password_login" value="ENTER     PASSWORD" style="color:#D9D9D9" style="vertical-align:middle"; onfocus="if     (this.value=='ENTER PASSWORD') {this.value=''; this.style.color='#696969';}" >
<input type="hidden" name="cookie_time" value="10080" />
<img src="../themes/default/images/arrow-red.png" alt="" /><input type="submit"   style="outline:grey" font-size="5px" value="[var.lang_login_now]" class="button-form2" />
<input type="hidden" name="submitted" value="yes" />
<input type="hidden" name="remember_me" value="remember_me" />
</p>
</form>
</div>
<!--Begin Sub-Navigation. This only appears when a user is logged in.-->
<div class="container1">
<div class="menu1">
<div class="sub-nav"><a href="../index.php"></a>&nbsp;<img     src="../themes/default/images/arrow-red.jpg" style="vertical-align:middle" alt="" /><a    href="../members/[var.user_name]"> my account</a><img src="../themes/default/images/arrow-    red.jpg" style="vertical-align:middle" alt="" />

<!--[onload;block=div;when [var.loggedin]=1;comm]-->
</div>

I was given this line of code:

if($_SESSION['loggedin'] == true){ //dont show form } else { //show form }

But I don't know how/where to integrate it into the Form. Any help will be appreciated.

Ok, I've spent a good part of the day trying to figure out what is going wrong with a client site. I introduced a link within document to send readers from the blogs home page to the comments section of individual posts. It's straight forward right? HTML1, been doing these kind of links for more than ten years.

#respond at the end of the normal URL in a normal anchor tag should bring the browser to id="respond" or name="respond" within the document. Right? But, a.) it doesn't. And b.) once it makes a jump everything above that point disappears. Space fills out to the same page height as if it existed but you can't scroll up.

You can see it in action at http://www.thebouncingbead.com/blog/ by clicking "Add Your Comment (0)" under the title of any post.

Can anyone see what might be causing this problem or experienced something similar before?

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?

I'm just learning about PHP and I'm diving in head first by attempting to modify our web site's contact form.  I'm wishing to stop the form from erasing previously entered values upon "failed" data validation.  It's of course going to be annoying to our visitors if their hardworked entries disappear just because they left out a name or entered an illegal email address.  I regret that some potential solutions found on this forum and other locations on Google didn't seem to help on my page.

As you can see, the validation is done with PHP's version of if-elseif-else.  Later I'll be adding a reCAPTCHA and I hope that whatever I learn here might be useful for the potentially same problem when I am adding the CAPTCHA. 

The actual contact form is at http://www.woofwoofwoof.org/contact/index.php.  Thank you in advance for your taking the time to help me what originally appeared to be a simple problem.  I have read the rules and I hope I've followed the rules -- please let me know if I committed any sins of omission or commission.  Now, for your Sunday reading pleasure, here's the code:

CODE STOPS HERE=====================================

Hello folks, well what I mean by temporary variables are variables like error messages or success messages that appear after a form has been submitted.  I want to be able to kill these variables when the page is refreshed and return the page to its defualt state.  For example, I'm making this simple page which is basically a form that ask users for some information, then upon submit, stores the  in a database and prints a success message.  If the form is filled out incorrectly or some form fields are left blank, then error messages are printed. What I really want is for these messages to disappear when the page is refreshed.  My current model uses a second page to handle the form, and then upon succes or upon encountering an error, redirects to the form page, passing the error or success variables via the url to the form page where they are printed out.  What can I do differently to achieve what I want (ie kill variables upon page refresh)? Below are the form page, and the page that handles the form respectively.

Code: [Select]

Also, another problem I just noticed is that, the errors[3] variable isn't getting passed back to the form page.  I don't know if it's because the url can only pass so much info to a second page. The page in question can be located he

Hi i am wondering how i can redirect someone that's not logged in?

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

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

Enlighten

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

Here is a link to screenshots of what is happening, because I'm crappy at describing things: http://imgur.com/a/ahvPA

Of course I've messed the code up somewhere, but I can't for the life of me figure out where. I have a simple page for someone to enter text in a textbox to save in a database to display on another page. There are 10 textboxes on the page. I can enter text into any and all textboxes and it'll save the data in the database, EXCEPT if I enter text into the 2nd textbox. If there's anything in the 2nd textbox after I click submit, it will delete whatever was in the 2nd textbox and move all data in each textbox (except textbox 1, which stays in the same place) down one element. And it pushes the data in the final textbox off the page (presumably because there's no other textbox to accept its data). Here is the code to the two pages affected. Any help would be appreciated!

It's been a while since I've needed to whip anything substantial up from scratch, so my scripting is a little (lot) fast and loose (weird/inefficient) here.

I'm trying to mock up a script that's essentially a quiz/survey. There are a handful of topics, each with a few screens of yes/no questions. At the end, it returns a list of recommendations based on the answers gathered.

The script is posting back to itself. Using print_r ($_SESSION), it seems like all of the post values for the first screen of questions are being assigned to the session array as expected. When the second screen of questions is answered, their values are assigned as well, but the values for the first set go away completely. This continues through subsequent screens, with the values from the previous screen present and all others before missing.

I'd really appreciate a look at my code to see if you tell me the cause or error(s).

Thanks!

hello i am stuck and hoping you can help, i have created this function and its not working correctly, what i am trying to do is
when someone is logged in they get this line of code echo "<a href=\"update-content.php?id=5\">Edit</a> | <a href=\"delete-content.php?id=5\">Delete</a>"; which is ok as i dont want that to work yet and if your not logged in you dont get it.
i have added //show when logged in and show not logged in so you know which code i want it to load when
at the moment its only loading the not logged in one even if you are.
i have looked on google read up on php sites but cant figure out how to do it, so hoping you guys will tell me were i gone wrong and how to correct it, thanks again

heres the code.

function get_left() {

        if (isset($_GET['page']))
 {

$page = $_GET['page'];

 

//Show Page not logged in
                $sql = "SELECT title,body FROM content WHERE page = '$page' AND location = 'left' AND disabled = 'no' ORDER BY id";
                $res = mysql_query($sql) or die (mysql_error());
                while($row = mysql_fetch_assoc($res)){

echo '<h1>' . $row['title'] . '</h1>';
                    echo '<p>' . $row['body'] . '</p>'; 

}

 }
//show when logged in
 elseif ($_SESSION['username']&&(isset($_GET['page']))){

$sql = "SELECT title,body FROM content WHERE page = '$page' AND location = 'left' AND disabled = 'no' ORDER BY id";
                $res = mysql_query($sql) or die (mysql_error());
                while($row = mysql_fetch_assoc($res)){

echo '<h1>' . $row['title'] . '</h1>';

                    echo '<p>' . $row['body'] . '</p>';

echo "<a href=\"update-content.php?id=5\">Edit</a> | <a href=\"delete-content.php?id=5\">Delete</a>"; 

}
 }
 }

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?
