title: Unexpected index on two variables in PHP form
body: <p>So doing a simple registration into database, but the value of <code>First Name</code> and <code>Last Name</code> is getting unexpected index but account type <code>username</code> is fine.</p>
  
  <p>HTML code:</p>
  
  <pre><code>&lt;form method="post" enctype="multipart/form-data" action="signIn.php"&gt;
  
          &lt;h3&gt;Create Your Account&lt;/h3&gt;
  
  
              Account Type
              &lt;select name="accountType"&gt; 
                      &lt;option&gt;Rentors&lt;/option&gt;
                      &lt;option&gt;Homeowners&lt;/option&gt;
               &lt;/select&gt;
  
              First Name:                
              &lt;input type="text" name"Fname" size="40"&gt;
  
              Last Name:
              &lt;input type="text" name"Lname" size="40"&gt;
  
              User Name:
              &lt;input type="text" name="username" size="40"&gt;
  
              Password:
              &lt;input type="password" name="password" size="40"&gt;
  
  
            &lt;input type="submit" name="signInformSubmit" value="SIGN UP"&gt;
  
          &lt;/form&gt;
  </code></pre>
  
  <p>PHP code I have tried isset on the <code>varFirstName</code> and <code>varLastName</code> and still no values in the database.</p>
  
  <pre><code>if ( isset($_POST['signInformSubmit']) ) 
  {
     $varAccountType = $_POST['accountType'];
     $varFirstName = isset($_POST['Fname']) ? $_POST['Fname']:'';
     $varLastName = isset($_POST['Lname']) ? $_POST['Lname']:'';
     $varUserName = $_POST['username'];
     $varPassword = $_POST['password'];
  
  }
  </code></pre>
  
  <p>/////////////////////connect and insert to database///////////////////</p>
  
  <pre><code>$mysqli = new mysqli("localhost","root","", "test");
  if ($mysqli-&gt;connect_errno) {
      echo "Failed to connect to MySQL: (" . $mysqli-&gt;connect_errno . ") " . $mysqli-&gt;connect_error;
  }
  
  /* Prepared statement, stage 1: prepare */
  $stmt = $mysqli-&gt;prepare("INSERT INTO accounts (accountType, FirstName, LastName, UserName, Password) VALUES (?,?,?,?,?)");
             /* Prepared statement, stage 2: bind and execute */
  $stmt-&gt;bind_param('sssss', $varAccountType,  $varFirstName, $varLastName, $varUserName, $varPassword);
  
  
  
  $stmt-&gt;execute();
  
      /*  explicit close recommended  */
  $stmt-&gt;close();
  
  $mysqli-&gt;close();
  
  ?&gt;
  </code></pre>
