title: Insert row into MySQL database with MySQLi
body: <p>Can someone spot the mistake:</p>
  
  <pre><code>mysqli_query($connection, "INSERT INTO comments (event_id, fulltext, date_posted) VALUES (5, 'Hallo', 430234)");
  </code></pre>
  
  <p>The connection is established, but it just doesn't insert a new row.</p>
  
  <pre><code>include("../../connect.php");
  
  $event_id = intval($_GET["event_id"]);
  $fulltext = $_GET["fulltext"];
  $date = intval($_GET["date"]);
  
  mysqli_query($connection, "INSERT INTO comments ('event_id', 'fulltext', 'date_posted') VALUES (5, 'Hallo', 430234)");
  
  echo "INSERT INTO comments (event_id, fulltext, date_posted) VALUES (5, 'Hallo', 430234)";
  
  mysqli_close($connection);
  </code></pre>
