title: Return Checkbox states: Form with errors: PHP
body: <p>I created a from with multiple required fields that the users my complete.  Then I also have 3 checkboxes of which the user must select at least one of them.  When the user submit the form I start doing the checks and each error I find I store in an array.  If there are any errors I display the errors for the user plus the form with the values that the user already entered.  This bit work fine.  I want to know how I would be able to return a checked checkbox if the user checked any of then and any amount, but none, fo them?  With from fields it's easy:</p>
  
  <pre><code>&lt;input type="text" name="First_Name" value="&lt;?php echo $First_Name; ?&gt;" /&gt;
  </code></pre>
  
  <p>My question is in what way I would be able to get the result of my checkbox the user select?  My guess is that it might be something like:</p>
  
  <pre><code>if(isset())
  </code></pre>
  
  <p>But I am not sure.  Any help on this please?</p>
