Whats wrong with this IF statement?

Snooble · January 30, 2007

[code] <?php
if($_SESSION['myemail']){
echo "Logged in as <strong>$_SESSION['fname'] $_SESSION['sname']</strong>. <br />
Click here to log out";
}else{
echo '<a href="loginotd.php" target="mainpage">Login</a><br />
<a href="javascript:void window.open('register.php','Checkout','status=no, scrollbars=1, height=790, width=560')">Register</a>';}
?>[/code]

I cant see it... I'm going blind i swear.

You're better off using something like isset()

[code]<?php
if (isset($_SESSION['myemail'])){
echo "Logged in as <strong>$_SESSION['fname'] $_SESSION['sname']</strong>. <br />\nClick here to log out";
}
else{
echo <<<HTML
<a href="loginotd.php" target="mainpage">Login</a><br />
<a href="javascript:void window.open('register.php','Checkout','status=no, scrollbars=1, height=790, width=560')">Register</a>
HTML;
}
?>[/code]

[b]Edit:[/b] Code corrected

lol i love you. Thank you once again. On my old thread i was told to use IF. But i get a blank page, so i assume there's a problem.

Snooble

:D Thanks

Your second echo is still messed up though. Look at the post, see where the colors go all funky? You need to escape quotes.

Snooble · January 30, 2007

yes you are right.

i'll have a play in dreamweaver. Thanks for that. I was just about to repost :)

I just assumed Huggy had it. Close! Will play around, thanks!

HuggieBear · January 30, 2007

Sorry, I just copied and pasted your code for that bit. Didn't check it.

Corrected the easy way! ;)

Huggie

Snooble · January 30, 2007

right...

I have some trouble i've taken out the last echo and just put "ndawodw" in its place. It still wont show the page. I assume the first statement must mess it up too..

Do you have session_start() at the top of the page? Try this and see where you get:
<?php
if (isset($_SESSION['myemail'])){
echo 'test1';
}
else{
echo 'test2';
}
?>

Snooble · January 30, 2007

I get the output :

test2

So its not set. I dont have session start at the top lol (should i be embarrassed) this is my first time using sessions mysql.

Could you explain? Should i create a page to include in each page's header?

HuggieBear · January 30, 2007

You must have [url=http://uk.php.net/manual/en/function.session-start.php]session_start()[/url] at the top of every page that uses sessions. It has to appear before anything gets output to the browser.

A quick read up on [url=http://uk.php.net/manual/en/ref.session.php]PHP's Sessions[/url] should help out here

Snooble · January 30, 2007

so in the header at the top before the styles i should add:

<?php
session_start()
*Now what? Variables?
?>

what do i put beneath session_start?

I am learning... honestly. Thank you so much

Snooble

HuggieBear · January 30, 2007

That's pretty much it for initialising sessions, just session_start() but I'd certainly advise reading the manual.

My advice in that case is to always have the PHP manual open beside your code. As far as I'm concerned, it's the best manual of any programming language I've ever worked with.

The main page is here: http://uk.php.net/manual/en/index.php (UK Mirror)

And from there you can type in any function name in the box at the top right of the page and be taken straight to the details of it.

"what do i put beneath session_start? "

The rest of your code.

Huggie: you know you can even just do php.net/function and it goes right to it? (I'm a sucker for any shortcuts)
so php.net/array is for arrays, php.net/substr, etc.

Snooble · January 30, 2007

I'm reading it as we speak. But it all seems so confusing :S.

I have the login box working. But i dont know what happens after that.

When i type session_start();

if i was logged in would it be able to post the firstname and second name that are stored in the database?

Thank you Huggy.

On your login page once you've authenticated a user, you can assign their details into session variables, then by placing session_start() at the top of any of your other pages on your site, you can retrieve those variables using the global $_SESSION array...

[b]login.php[/b]
[code]<?php
// Start the session
session_start();

// Get my user details from the form
$user = $_GET['frmUser'];
$pass = $_GET['frmPass'];

// My database query to authenticate the user would go here
$sql = "SELECT real_name FROM users WHERE ....."; // get the idea

// Process the query here with mysql_query()
$result = mysql_query($sql) or die ("Unable to execute $sql: " . mysql_error());

// Put the persons real name into a session variable
$details = mysql_fetch_array($result, MYSQL_ASSOC);
$_SESSION['name'] = $details['real_name'];
?>[/code]

Now to echo that on page two all I do is this:

[b]page2.php[/b]
[code]<?php
// Start the session again
session_start();

// Check for username
if (isset($_SESSION['name'])){
echo "Welcome " . SESSION['name']
}
else {
header('Location: login.php');
}
?>[/code]

Now you can have a good look at the site and what i want to achieve.

I just want the fields to be carried around the site at all times when they are logged in. I will make a log out button using session_destroy();

Thank you and i hope this information makes it clearer.
