body: <p>Been struggling with this some time now and is probably something simple...</p>
  
  <p>I keep getting the following error whilst trying to submit a contact form</p>
  
  <blockquote>
    <p>Warning: implode() [function.implode]: Invalid arguments passed in .... on line 240.</p>
  </blockquote>
  
  <p>HTML CODE</p>
  
  <pre><code>&lt;input type="checkbox" name="socialmedia[]" value="Facebook"&gt;Facebook&lt;br&gt;
  &lt;input type="checkbox" name="socialmedia[]" value="Twitter"&gt;Twitter&lt;br&gt;
  &lt;input type="checkbox" name="socialmedia[]" value="YouTube"&gt;YouTube&lt;br&gt;
  &lt;input type="checkbox" name="socialmedia[]" value="Flickr"&gt;Flickr&lt;br&gt;
  &lt;input type="checkbox" name="socialmedia[]" value="Vimeo"&gt;Vimeo&lt;br&gt;
  </code></pre>
  
  <p>PHP CODE</p>
  
  <pre><code>$socialmedia = array();
  $socialmedia = implode(",",$_POST['socialmedia']);
  </code></pre>
