    <p>I'm trying to create a login and registration system with PHP for a school assignment, but it's currently not really working... </p> <p>The problem is it generates an error saying the fields are empty, even when you filled the fields in with data, so it shouldn't give this error.</p> <p>The code:</p> <pre><code> &lt;html&gt; &lt;head&gt; &lt;title&gt;Music Database&lt;/title&gt; &lt;link rel="stylesheet" href="layout.css" type="text/css" /&gt; &lt;?php // Verbinden met de database // include('connect.php'); // Registreer data verkrijgen en in variabelen zetten // if(isset($_POST['r_submit'])){ $r_username = $_POST['r_username']; $r_password = $_POST['r_password']; $confirm_r_password = $_POST['confirm_r_password']; $r_name = $_POST['r_name']; $r_surname = $_POST['r_surname']; $r_birth = $_POST['r_dateofbirth']; $r_mail = $_POST['r_mail']; } ?&gt; &lt;/head&gt; &lt;body&gt; &lt;div id="login"&gt; &lt;form name="login" action="login.php" method="post"&gt; &lt;p&gt;Login: &lt;input class="input" type="text" name="username" value="Username" /&gt; &lt;input id="password" type="password" name="password" value="Password" /&gt;&lt;/p&gt; &lt;div&gt;&lt;a class="link" href="register.php"&gt;Register here!&lt;/a&gt;&lt;/div&gt; &lt;p align="center"&gt;&lt;input class="submit" type="submit" name="login_submit" value="Submit" /&gt;&lt;/p&gt; &lt;/form&gt; &lt;/div&gt; &lt;div id="header"&gt; &lt;a class="link" href="index.php"&gt;Music Database&lt;/a&gt; &lt;/div&gt; &lt;div id="search"&gt; &lt;form name="search" action="search.php" method="post"&gt; &lt;p&gt;Search for: &lt;input class="input" type="text" name="search" value="&lt;?php if(isset($_POST['search'])) print $_POST['search']; ?&gt;" /&gt; &lt;input class="submit" type="submit" name="search_submit" value="Submit" /&gt;&lt;/p&gt; &lt;p&gt;Artist: &lt;input type="checkbox" name="artistsearch" checked /&gt; Album: &lt;input type="checkbox" name="albumsearch" /&gt; Song: &lt;input type="checkbox" name="songsearch" /&gt; Genre: &lt;input type="checkbox" name="genresearch" /&gt;&lt;/p&gt; &lt;/form&gt; &lt;/div&gt; &lt;div id="wrapper"&gt;&lt;br /&gt;&lt;/div&gt; &lt;div id="content"&gt; &lt;h1&gt;Register down here please:&lt;/h1&gt; &lt;table id="wrap_table"&gt; &lt;tr&gt; &lt;td&gt; &lt;div id="reg_content"&gt; &lt;div id="reg_form"&gt; &lt;form name="register_login" action="register.php" method="post"&gt; &lt;fieldset&gt; &lt;legend&gt;Login Data: &lt;/legend&gt; &lt;table class="r_table"&gt; &lt;tr&gt; &lt;td&gt;Username&lt;sup&gt;*&lt;/sup&gt;: &lt;/td&gt; &lt;td&gt;&lt;input class="input" type="text" name="r_username" value="&lt;?php if(isset($r_username)){ print $_POST['r_username']; } ?&gt;"/&gt;&lt;/td&gt; &lt;?php if(isset($_POST['r_submit'])){ if(!isset($r_username)){ echo "&lt;td&gt;Error: No Username has been entered!&lt;/td&gt;"; } } ?&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;Password&lt;sup&gt;*&lt;/sup&gt;: &lt;/td&gt; &lt;td&gt;&lt;input class="input" type="password" name="r_password" value="&lt;?php if(isset($r_password)){ print $_POST['r_password']; } ?&gt;"/&gt;&lt;/td&gt; &lt;?php if(isset($_POST['r_submit'])){ if(!isset($r_password)){ echo "&lt;td&gt;Error: No Password has been entered!&lt;/td&gt;"; } } ?&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;Confirm Password&lt;sup&gt;*&lt;/sup&gt;: &lt;/td&gt; &lt;td&gt;&lt;input class="input" type="password" name="confirm_r_password" value="&lt;?php if(isset($confirm_r_password)){ print $_POST['confirm_r_password']; } ?&gt;"/&gt;&lt;/td&gt; &lt;?php if(isset($confirm_password)){ if($confirm_r_password != $r_password){ echo "&lt;td&gt;Error: The passwords don't match!&lt;/td&gt;"; } } ?&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/fieldset&gt; &lt;/form&gt; &lt;/div&gt; &lt;/td&gt; &lt;td&gt; &lt;div id="reg_form"&gt; &lt;form name="register_personal" action="register.php" method="post"&gt; &lt;fieldset&gt; &lt;legend&gt;Personal Data: &lt;/legend&gt; &lt;table class="r_table_personal"&gt; &lt;tr&gt; &lt;td&gt;Name: &lt;/td&gt; &lt;td&gt;&lt;input class="input" type="text" name="r_name" value=""/&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;Surname: &lt;/td&gt; &lt;td&gt;&lt;input class="input" type="text" name="r_surname" value=""/&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;Date of Birth: &lt;/td&gt; &lt;td&gt;&lt;input class="input" type="text" name="r_dateofbirth" value=""/&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;E-mail&lt;sup&gt;*&lt;/sup&gt;: &lt;/td&gt; &lt;td&gt;&lt;input class="input" type="text" name="r_mail" value="&lt;?php if(isset($r_mail)){ print $_POST['r_mail']; } ?&gt;"/&gt;&lt;/td&gt; &lt;?php if(isset($_POST['r_submit'])){ if(!isset($r_mail)){ echo "&lt;td&gt;Error: No E-mail has been entered!&lt;/td&gt;"; } } ?&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/fieldset&gt; &lt;/form&gt; &lt;/div&gt; &lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;Fields with an asterisk&lt;sup&gt;*&lt;/sup&gt; are required for registry!

    1. COAre the 2 pieces of code in different php files? What is the execution order? If you execute the html part **before** the second piece of code, you'll get that error because the `$r_username`, `$r_password`, etc variables are not defines

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).
