title: Adding and getting another new textbox if select dropdown in HTML PHP
body: <p>Current code snippets</p>
  
  <p>HTML</p>
  
  <pre><code>&lt;form action="" method="post"&gt;
  &lt;select name="Particulars"&gt;
  &lt;option value="Username"&gt;Username&lt;/option&gt;
  &lt;option value="Email"&gt;Email&lt;/option&gt;
  &lt;option value="Address"&gt;Address&lt;/option&gt;
  &lt;/select&gt;
  &lt;input type="submit" name="submit" value="Get Selected Values" /&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>PHP </p>
  
  <pre><code>&lt;?php
  if(isset($_POST['submit'])){
  $selected_val = $_POST['Particulars'];  // Storing Selected Value In Variable
  echo $selected_val;  // Displaying Selected Value
  }
  </code></pre>
  
  <p>So for example, if i select Username, i will want another new text box to come out so I can type in value inside and submit, is there any way I can do it? Currently I am only able to echo out the value, but not a brand new text box. Sorry, english is not my first language, Thank you so much! :) </p>
  
  <p>I will keep updating and showing what I've done here. </p>
