HTML PHP Display username after success login
I have a <div>
inside my onlinestore.html file which is my menu that contain of Login/Register. What I want is after the success login, the <div>
for login/register change to the username. What i'hv done wont display the expected output that i want.So is there something wrong about my code?
Here is what I've done:
onlinestore.html
<li class='active' style='float:right;'>
<?php
session_start();
if($_SESSION['logged']==true){
echo $_SESSION["username"];
echo '<a href="logout.php"><span>Logout</span></a></li>';
}
elseif($_SESSION['logged']==false)
echo '<a href="registerform.html"><span>Login/Register</span></a></li>';
?>
Here is another file checklogin.php:
if($count==1){
session_start();
$_SESSION['logged']=true;
$_SESSION ['username']=$myusername;
header("refresh:1;url=onlinestore.html");
}
else{
$_SESSION['logged']=false;
header("refresh:2;url=login.html");}
Here is the expected output:
Before Login
After Login
Here is what i get with the code above:
Either you need to rename your onlinestore.html
and login.html
to be .php files so the PHP will work in them, or use the addtype option in your htaccess file.
In your onlinestore.html
do this:
<?php
session_start(); // Right at the top of your script
?>
<li class='active' style='float:right;'>
<?php
if($_SESSION['logged']==true)
{
echo $_SESSION["username"];
echo '<a href="logout.php"><span>Logout</span></a></li>';
}
elseif($_SESSION['logged']==false)
{
echo '<a href="registerform.html"><span>Login/Register</span></a></li>';
}
?>
In your checklogin.php
do this:
<?php
session_start(); // Right at the top of your script
?>
if($count==1)
{
$_SESSION['logged']=true;
$_SESSION['username']=$myusername;
header("Location: onlinestore.html");
exit();
}
else
{
$_SESSION['logged']=false;
header("Location: login.html");
exit();
}
If the above doesn't work then please tell me what happens.
Do you have html files set to parse PHP code?
Or a htaccess file with:
AddType application/x-httpd-php .htm .html
?
EDIT
Try this for debugging:
In your checklogin.php
do this:
<?php
session_start(); // Right at the top of your script
?>
if($count==1)
{
$_SESSION['logged']=true;
$_SESSION['username']=$myusername;
echo "Login worked";
exit();
}
else
{
$_SESSION['logged']=false;
echo "Login failed";
exit();
}
This will show you if login is working. If it's not and you get "login failed" then that is why you get the "Login/Register" link on your page.
If it shows "Login worked" then set the code back to how it was and then on your onlinestore.html
page, do this at the top of the file:
echo "This is working";
exit();
What happens? Do you get the message "This is working" on the page and nothing else?
In your else
statement you haven't defined a session_start()
like you did in your if
statement.
And else, instead of checking the value of a $_SESSION and determining the value of it, you can use the following:
if (session_status() == PHP_SESSION_NONE) {
//Do something if the session is not existing
}
Other options are storing variables in a $_COOKIE
and then check if it isset
or not( if(isset($_COOKIE["username"]){}
)
I hope this has helped you out
如果您希望显示用户名,则需要将onlinestore.html的代码更改为以下内容:
<li class='active' style='float:right;'>
<?php
session_start();
if($_SESSION['logged']==true){
echo '<a href="logout.php"><span>' + $_SESSION["username"] + ' (Logout)</span></a></li>';
}
elseif($_SESSION['logged']==false)
echo '<a href="registerform.html"><span>Login/Register</span></a></li>';
?>
