davemoody Posted August 13, 2011 Share Posted August 13, 2011 I am trying really REALLY hard to load an element from an xml file into an array. It is for the purpose of testing username and password for a login system. I need to locate the correct username, and then compare the password. My idea is to find the username and then load all that entire element with all childs into an array (all elements needed for prefilling shopping cart form later) which can then be saved to the session. Obviously the username and password need to be tested together as well for login to succeed. The code below shows an experiment just to load a tag and print it out, can't even get that to work... Here's the full code of my login file: <?php $error = false; if(isset($_POST['login'])) { $username = preg_replace('/[^A-Za-z0-9]/','', $_POST['username']); $password = md5($_POST['password']); $doc = new DomDocument(); $doc->load( "users/users.xml" ); $usernames = $doc->getElementsByTagName( "username" ); foreach( $Usernames as $username ) { $usernames = $username->getElementsByTagName( "username" ); $username = $usernames->item(0)->nodeValue; echo "<b>" . $username . "<p />"; } } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>[Login Page] Transform Your Life - Transform Your World...</title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <link rel="shortcut icon" href="images/favicon.ico" /> <link rel="stylesheet" type="text/css" href="style/template.css" /> </head> <body> <div> <!--Header--> <div class="header"> <?php include 'header.php'; ?> <div class="infoblock2"> <form method="post" action=""> <ul class="login"> <li class="login2">Login:</li> <li class="login2">Username <input type="text" name="username" size="25" /></li> <li class="login2">Password <input type="password" name="password" size="25" /></li> <li class="login2"><?php if($error) { echo '<p />Invalid Username and/or Password'; } ?> <input type="submit" value="Login" name="login" /></li> <li class="login2"><a href="registration.php">Register</a></li> </ul> </form> </div> </div> </div> </body> </html> And here's the xml file: <?xml version="1.0"?> <Users> <User> <password>098f6bcd4621d373cade4e832627b4f6</password> <email>a@a.com</email> <username>a</username> <firstname>a</firstname> <lastname>a</lastname> <age>67</age> <street>a</street> <city>a</city> <state>a</state> <country>Thailand</country> </User> <User> <password>7694f4a66316e53c8cdd9d9954bd611d</password> <email>q@q.com</email> <username>qq</username> <firstname>q</firstname> <lastname>q</lastname> <age>33</age> <street>q</street> <city>q</city> <state>q</state> <country>Thailand</country> </User> </Users> I've tried about a dozen different pieces of code found on the net, tried writing my own, all fail miserably. What am I doing wrong? Quote Link to comment Share on other sites More sharing options...
jcbones Posted August 13, 2011 Share Posted August 13, 2011 Try this: <?php $doc = new DomDocument(); $doc->validateOnParse = true; if(!$doc->load("users/users.xml")) { exit('Error occured!'); } $userList = $doc->getElementsByTagName('username'); $userCnt = $userList->length; for ($idx = 0; $idx < $userCnt; $idx++) { echo 'Username: ' . $userList->item($idx)->nodeValue . "<br />"; } ?> Quote Link to comment Share on other sites More sharing options...
