title: I am trying to do HTML and PHP to load and save a text file to the server
body: <p>desired sequence:</p>
  
  <blockquote>
    <p>SaveButton<br>
       LoadButton
       When the "load button" is pressed, load a textfile from the server into a textbox.<br>
       Allow the user to add text<br>
       When the "save button" is pressed, save the textbox text to the server.   </p>
  </blockquote>
  
  <p>I am having issues with callbacks not executing.</p>
  
  <p>I am worried about the callbacks, I know how to save a file.</p>
  
  <pre><code>&lt;html&gt;
  &lt;body&gt;
  &lt;button id="1" onClick="reply_click(id)"&gt;Load&lt;/button&gt;
  &lt;button id="2" onClick="reply_click(id)"&gt;Save&lt;/button&gt;
  &lt;?php
  function reply_click($clicked_id)
  {
      echo "hello ";
  }
  ?&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
