title: HTML, Set input to add additional parameters
body: <p>I got input field near my pagination that let you type to required page, The problem is that when the page number you asked is submitted it erase the parameters was already embedded to the url, I will explain:</p>
  
  <p><strong>Current parameter:</strong></p>
  
  <pre><code>somewebpage.org?xparam=5
  </code></pre>
  
  <p><strong>This is my form:</strong></p>
  
  <pre><code>&lt;form method="get" action=""&gt;&lt;input type="submit"&gt;&lt;input type="text" name="page"&gt;&lt;/form&gt;
  </code></pre>
  
  <p><strong>#1 try to keep the parameter after submission</strong></p>
  
  <pre><code>somewebpage.org?xparam=5&amp;page=3
  </code></pre>
  
  <p><strong>Now i did try to do:</strong></p>
  
  <pre><code>&lt;form method="get" action="?xparam=5"&gt;&lt;input type="submit"&gt;&lt;input type="text" name="page"&gt;
  </code></pre>
  
  <p><strong>No result, #2 try to keep the parameter after submission</strong></p>
  
  <pre><code>&lt;form method="get" action="&amp;xparam=5"&gt;&lt;input type="submit"&gt;&lt;input type="text" name="page"&gt;
  </code></pre>
  
  <p><strong>And the url became: somewebpage.org&amp;xparam=5?page=3</strong></p>
  
  <p>Does anyone know a way to set the input to add the parameter as additional or any other solution.</p>
