title: PHP if checkbox was checked and now wasn't (and opposite)?
body: <p>I am thinking this is doable? Maybe?</p>
  
  <p>Here is my checkbox input:</p>
  
  <pre><code>&lt;input  type='checkbox' name='cb_name' id='cb_name' checked='checked' /&gt;
  </code></pre>
  
  <p>I Need an if else statement that checks only if the Checkbox was changed.</p>
  
  <p>I have other input fields on the form. And if the checkbox wasn't touched or checked, then SAVE the form without doing the checkbox condition.</p>
  
  <p>If checkbox was checked before and now is != 'checked' then do this.</p>
  
  <p>&amp;&amp;</p>
  
  <p>If checkbox was != 'checked' before and now is = 'checked' then do this.</p>
  
  <p>&amp;&amp;</p>
  
  <p>and then finally, if checkbox was left alone (NO VALUE WAS CHANGED) then do the other form stuff without running the checkbox condition statement??</p>
