Hello,
I'm very new to PHP and am trying to code a basic content management system. Every time I try and test my login I get a blank page and the same notice pops up:
Notice: Undefined index: action in test\newsite\transact-user.php on line 10
I've searched high and low for answers and have tried several: changed my error_reporting, tried declaring the problem index, etc. Here is the problem code:
<?php
require_once 'conn.php';
require_once 'http.php';
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting (E_ALL);
if (!isset($_REQUEST['action'])) {
switch ($_REQUEST['action']) {
case 'Login':
if (isset($_POST['username'])
and isset($_POST['password']))
{
$sql = "SELECT user_id, access_level,first_name " .
"FROM user_info " .
"WHERE username='" . $_POST['username'] . "' " .
"AND password='" . $_POST['password'] . "'";
$result = mysql_query($sql, $conn)
or die('Could not look up user information; ' .
mysql_error());
if ($row = mysql_fetch_array($result)) {
session_start();
$_SESSION['user_id'] = $row['user_id'];
$_SESSION['access_level'] = $row['access_level'];
$_SESSION['first_name'] = $row['first_name'];
}
}
redirect('/index.php');
break;My login area looks like this:
<div id="navright">
<?php if (!isset($_SESSION['user_id'])){
echo '<form method="post" action="transact-user.php">';
echo '<fieldset>';
echo '<label for="username">USERNAME: </label><input type="text" id="username" name="username" class="formInput" /><br />';
echo '<label for="password">PASSWORD: </label><input type="password" id="password" name="password" class="formInput" /><br />';
echo '<input id="submit" name="action" type="submit" value="LOGIN" class="submitB" />';
echo '</fieldset>';
echo '</form>';
} ?>
</div>The weird thing is that this worked before on several occasions, but then it all of a sudden quit working and leaves me with a blank page. Any help is very much appreciated!
