i have this div that is positioned nice on my banner
but the php echo is not echoing where the div is positioned on the page. its echoing at the very top of the page even though i put the php in the div.


here is the code:

<?php
session_start();
if(isset($_POST['submit1'])) {
logout();
}
?>

<div id="apDiv6"><!-- logout echo here-->
<?php

function logout()
{

      if ($_SESSION['u_name'])
      {
            session_destroy();
      echo "You've been logged out.";}
      else{
            echo "You where not logged in!";
            }        
}
?>
</div>

<div id="two"><!-- logout button here-->

<form action="<?=$_SERVER['PHP_SELF'];?>" method="POST">
<table width="65" border="0" cellpadding="1" cellspacing="3" class="table1">
<td width="57">
<input type="submit" name="submit1" value="Log out"></td>
</table>
</form>
</div>

#apDiv6 {/*css postitions for my echo*/
      position:absolute;
      width:458px;
      height:45px;
      z-index:4;
      left: 183px;
      top: 61px;
}
i allso have some more css for the button here to. what i show here is just a part of my code

so how come the echo is not displayed where i placed the div?
i just want my echo to be displayed in the place i want to position it at :( was working a few hours ago.

      if ($_SESSION['u_name'])
      {
            session_destroy();
      echo "You've been logged out.";}
      else{
            echo "You where not logged in!";
            }    

Open in new window

 if ($_SESSION['u_name']) {
	session_destroy();
	echo "You've been logged out.";}
else{
	echo "You where not logged in!";
}

What if you add <p> and </p>.
if ($_SESSION['u_name']) {
        session_destroy();
        echo "<p>You've been logged out.</p>";
}else{
        echo "<p>You where not logged in!</p>";
}  

Open in new window

Also I have rewrote the code and made it nicer if you're interested (you want to put echo after the logout button right?).

Here's the rewritten code.  
<?php
session_start();
if(isset($_POST['submit1'])) {
	logout();
}

/* This function checks if $_SESSION['u_name'] is open and 
 * if it is it destroys(deletes) the session and writes 
 * something into variable $logoutmessage, otherwise
 * it writes something else into variable $logoutmessage.
 * Global indicates that $logoutmessage can also be used 
 * outside of function. */
function logout() {
	global $logoutmessage;
	if ($_SESSION['u_name']) {
		session_destroy();
		$logoutmessage = "<p>You've been logged out<p>";
	} else {
		$logoutmessage = "<p>You've been logged out<p>";
	}        
}
/* If the logoutmessage isn't set it's null */
if (!isset($logoutmessage)) {
	$logoutmessage = "";
}
/* Now we echo everything we want (EHTML marks it as html instead 
 * plain like in normal echo and also we can use both " and ')*/
echo  <<<EOHTML
<div id="two"><!-- logout button here-->
<form action="{$_SERVER['PHP_SELF']}" method="POST">
<table width="65" border="0" cellpadding="1" cellspacing="3" class="table1">
<td width="57">
<input type="submit" name="submit1" value="Log out"></td>
</div>
</table>
</form>
<div id="apDiv6"><!-- logout echo here-->
$logoutmessage
</div>
EOHTML;
?>

Open in new window

Ups a mistake on line 19 of code in my last post. Should be You were not logged in instead of You've been logged out
