CodePudding user response：

In the HTML form

<form method="post">
 Enter Your Text Here:<br>
 <input type="text" name="textdata"><br>

 <!-- New fields -->
 <input type="text" name="subject"/>
 <input type="text" name="subject2"/>
  
 <input type="submit" name="submit">
 
</form>

In the PHP code

$subject = $_POST['subject'];
$subject2 = $_POST['subject2'];

Additional notes : Taking form data directly like the above is risky. You need to sanitize the input values.

E.g.

$subject = addslashes($_POST['subject']);

In the php form or html form, you can use the code below

<form method="POST">
<label>Enter Your Text Here:</label>

<!-- New fields form -->
<input type="text" name="username"/>
<input type="text" name="email"/>
<input type="text" name="subject"/>
<input type="text" name="subject2"/>
<input type="text" name="subjet3"/> 
<input type="submit" name="submit"> 
</form>

Code processed by php in below

$username = $_POST['username'];
$email = $_POST['email'];
$subject = $_POST['subject'];
$subject2 = $_POST['subject2'];
$subjet3 = $_POST['subjet3'];
