    <p>On my offline dev server, I have the following code:</p> <pre><code>&lt;?php //submit_build.php include_once 'header.php'; require_once 'login_users.php'; include_once 'functions.php'; if(empty($_SESSION['username'])) die ("You must be logged in to use this page"); $choice = $_GET['choice']; $db_server = mysql_connect($db_hostname, $db_username, $db_password); mysql_select_db($db_database) or die("Unable to select database: " . mysql_error()); if (isset($_POST['buildname']) &amp;&amp; isset($_POST['weapon']) &amp;&amp; isset($_POST['mod1']) &amp;&amp; isset($_POST['description']) &amp;&amp; isset($_POST['category']) &amp;&amp; isset($_POST['hidden']) &amp;&amp; isset($_POST['password'])) { $buildname = clean(sanitizeString($_POST['buildname'])); $buildurl = urlencode($buildname); $section = $choice; $weapon = sanitizeString($_POST['weapon']); $modcap = sanitizeString($_POST['modcap']); $mod1 = sanitizeString($_POST['mod1']); $mod2 = sanitizeString($_POST['mod2']); $mod3 = sanitizeString($_POST['mod3']); $mod4 = sanitizeString($_POST['mod4']); $mod5 = sanitizeString($_POST['mod5']); $mod6 = sanitizeString($_POST['mod6']); $mod7 = sanitizeString($_POST['mod7']); $mod8 = sanitizeString($_POST['mod8']); $polarity1 = sanitizeString($_POST['polarity1']); $polarity2 = sanitizeString($_POST['polarity2']); $polarity3 = sanitizeString($_POST['polarity3']); $polarity4 = sanitizeString($_POST['polarity4']); $polarity5 = sanitizeString($_POST['polarity5']); $polarity6 = sanitizeString($_POST['polarity6']); $polarity7 = sanitizeString($_POST['polarity7']); $polarity8 = sanitizeString($_POST['polarity8']); $description = sanitizeString($_POST['description']); $category = sanitizeString($_POST['category']); $hidden = sanitizeString($_POST['hidden']); $pw_check = sanitizeString($_POST['password']); $pw_check = md5($pw_check); if ($pw_check == ($_SESSION['password'])) { $add_build = "INSERT INTO weapons VALUES(NULL,'$username', '$buildname', '$section', '$weapon', '$modcap', '$mod1', '$mod2', '$mod3', '$mod4', '$mod5', '$mod6', '$mod7', '$mod8', '$polarity1', '$polarity2', '$polarity3', '$polarity4', '$polarity5', '$polarity6', '$polarity7', '$polarity8', '$category', '$hidden', '$description', NULL, '{$_SESSION['ipaddress']}', '$buildurl')"; mysql_query($add_build); header("Location: account.php"); } else{ die("Incorrect password."); } } </code></pre> <p>Followed by some more PHP, and HTML later on in the document. </p> <p><strong>NOTE The file header.php contains HTML.</strong></p> <p>My code works perfectly offline. I can click submit, and I will be redirected to account.php.</p> <p>However as soon as I upload the files to my remote server, the code still works perfectly but the redirect does not. Instead of redirecting, it just brings me back to the same page. The data that was entered DOES however get submitted to MySQL, so it's just the redirect that isnt working.</p> <p>Can someone tell me how I would get this </p> <p>header(Location: account.php);</p> <p>to work? Where should I place it? Or where should I move</p> <p>include_once 'header.php';</p> <p>to make it work?</p> <p>Thanks so much!</p> <p>EDIT:</p> <p>Here is my authenticate.php file.. up to where the html begins. Maybe you can see an issue here.</p> <pre><code>&lt;?php // authenticate.php include_once 'functions.php'; require_once 'login_users.php'; $db_server = mysql_connect($db_hostname, $db_username, $db_password); if (!$db_server) die("Unable to connect to database:" . mysql_error()); mysql_select_db($db_database) or die("Unable to find database:" . mysql_error()); if (!empty($_POST['username']) &amp;&amp; (!empty($_POST['pw_temp']))) { $username = sanitizeString($_POST['username']); $pw_temp = sanitizeString($_POST['pw_temp']); $pw_temp = md5($pw_temp); $query = "SELECT username,password FROM users WHERE username='$username' AND password='$pw_temp'"; if (mysql_num_rows(mysql_query($query)) == 0) { die("Wrong info"); } else { session_start(); $_SESSION['username'] = $username; $_SESSION['password'] = $pw_temp; $_SESSION['ipaddress'] = $_SERVER['REMOTE_ADDR']; header('Location: index.php'); exit; } }else{ include_once 'header.php'; echo &lt;&lt;&lt;_END &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; </code></pre>

    1. COAs far as I remember, `header(location:)` will not work if data has already been sent. It's always good to [read the manual](http://php.net/manual/en/function.header.php).

    2. COAs a side note, this won't change your problem, but mysql_* is deprecated. It's highly recommended that you switch ASAP, for security and performance reasons: [Why shouldn't I use mysql_* functions in PHP?](http://stackoverflow.com/questions/12859942/why-shouldnt-i-use-mysql-functions-in-php)

    3. COYou could always move header.php right before the other html on the page, after the call to header() at least.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
