    <p>I have this problem with my web system. As administrator, my purpose is to register some users giving them <code>username</code>,<code>password</code>,<code>firstname</code> and <code>lastname</code>. I do that properly since all the records are inserted correctly. But when I'm trying to have access as one of those users, I cannot enter, geting the message <strong>"Username and password do not match"</strong>. This is my login check code: </p> <pre><code> if (isset($_POST['username']) &amp;&amp; isset($_POST['password'])) { $username = $_POST['username']; $password = $_POST['password']; $_SESSION['username'] = $_POST['username']; if ((!$username) || (!$password)) { do_html_header(''); echo '&lt;h3 style="color:#800000;"&gt;Please fill in both fields&lt;/h3&gt;&lt;br&gt;&lt;br&gt;&lt;/br&gt;&lt;/br&gt;'; display_login_form(); } else { $sql = mysql_query('SELECT * FROM members WHERE username="'.$_POST['username'].'" AND password=sha1("'.$_POST['password'].'")') or die(mysql_error()); $login_check_member = mysql_num_rows($sql); if($login_check_member &gt; 0) { while($row = mysql_fetch_array($sql)) { $role = $row["role"]; $_SESSION['role'] = $role; } } else { // Run this code if login_check is equal to 0 meaning they do not exist do_html_header(''); echo '&lt;h3 style="color:#800000;"&gt;The Username And Password do not match.&lt;/h3&gt;&lt;br&gt;&lt;br&gt;&lt;/br&gt;&lt;/br&gt;'; display_login_form(); } </code></pre> <p>Apparently, there is a problem with my while loop. But it does work properly for those users inserted in my database via MySql console of wampserver. The problem exists only for the users inserted via the web site. The part of code that I use to insert new users (servers) is :</p> <pre><code>$username = $_POST['username']; $password = $_POST['password']; $firstname = $_POST['firstname']; $lastname = $_POST['lastname']; $role = $_POST['role']; $conn = mysql_connect("localhost", "root", ""); $db=mysql_select_db("buzzcafe" ,$conn); //$username= $_SESSION['username']; if (isset($_POST['username'])) { if (isset($_POST['password'])) { if (isset($_POST['firstname'])) { if (isset($_POST['lastname'])) { if(isset($_POST['role'])) { $insertServer = mysql_query("INSERT INTO servers (username,password,firstname,lastname,role) VALUES('".$username."',sha1('".$password."'),'".$firstname."','".$lastname."','".$role."')")or die(mysql_error()); echo "&lt;h5 style=color:#800000&gt;&lt;i&gt;The server ".$username." is now registered &lt;/i&gt;&lt;/h5&gt;"; display_manager_menu(); } } } } } </code></pre> <p>Any ideas please? </p>

    1. COOT: You can give multiple arguments to `isset()`, it will check that they're all set. So you can replace all those nested `if`s with a single call.

    2. COWhy do you think the problem is the `while` loop? The `if` statement doesn't go into the `while` loop if it displays the `do not match` message.

    3. COYour INSERT is into `servers`; the SELECT is from `members`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
