title: How to add additional parameters on a form, submitting it with GET method
body: <p>I have this form :</p>
  
  <pre><code>&lt;form method='GET' name='search' action='index.php?explore=search'&gt; 
      &lt;input type="hidden" name="searchType" value="all" /&gt;
      &lt;input class="inputSearchSmall" name="search"&gt;
  &lt;/form&gt;
  &lt;a href="javascript:document.search.submit()"&gt;&lt;img src="img/button_search.png" class="buttonSearch" /&gt;&lt;/a&gt;
  </code></pre>
  
  <p>and I'd like to add parameters on the query string, after the action link. So, the result must be:</p>
  
  <pre><code>http://localhost:8080/website/index.php?explore=search&amp;searchType=all&amp;search=example
  </code></pre>
  
  <p>not :</p>
  
  <pre><code>http://localhost:8080/website/index.php?searchType=all&amp;search=example
  </code></pre>
  
  <p>what's the best way to do this? Adding a hidden param like :</p>
  
  <pre><code>&lt;input type="hidden" name="explore" value="search" /&gt;
  </code></pre>
  
  <p>Or can I concatenate the parameters to the action script in some way?</p>
