PHP show records from mysql

Question

Im blocked at following part of code...

i have config.php page, with following code inside:

<?php
// Start the session (pretty important!)
session_start();

// Establish a link to the database
$dbLink = mysql_connect('localhost', 'USER', 'PASS');
if (!$dbLink) die('Can\'t establish a connection to the database: ' . mysql_error());

$dbSelected = mysql_select_db('DATABASE', $dbLink);
if (!$dbSelected) die ('We\'re connected, but can\'t use the table: ' . mysql_error());

$isUserLoggedIn = false;  
$query      = 'SELECT * FROM users WHERE session_id = "' . session_id() . '" LIMIT 1';  
$userResult     = mysql_query($query);  
if(mysql_num_rows($userResult) == 1){  
$_SESSION['user'] = mysql_fetch_assoc($userResult);  
$isUserLoggedIn = true;  
}else{  
if(basename($_SERVER['PHP_SELF']) != 'index.php'){  
    header('Location: index.php');  
    exit;  
}  
}  
?>

Now i have another page, with following code inside:

<?php include_once('config.php'); ?>

<?php foreach($_SESSION['user'] as $key => $value){ ?>
<li><?php echo $key; ?> <strong><?php echo $value; ?></strong></li>
<?php } ?>

That code show me all informations stored in database, one by one..

I want to show informations, individualy in my page, something like:

<?php echo $email; ?>

etcetera..

Can someone explain me how to do that?

Thank you

Answer 1

You should output it like

<?php echo $_SESSION['user']['email'] ?>

assuming that 'email' is the column name in the users table.

Answer 2

只需解决关联数组中的相关字段：

  <?php echo $value['email';?>

Answer 3

Use this in the config file:

$_SESSION['user']['email'] = mysql_fetch_assoc($userResult); 

instead of this

$_SESSION['user'] = mysql_fetch_assoc($userResult); 

in your code. You can pass as many columns you want to pass from your table.

And in another page use

foreach($_SESSION['user']['email'] as $key => $value) 

instead of

foreach($_SESSION['user'] as $key => $value) 

in your code.

Remember number of columns you pass in config file, all those columns should be called in this page.
