title: File_get_html url variable from input search FORM
body: <p>I have this code to retrieve a <code>&lt;table&gt;</code> content with <code>id="item_specification"</code>:</p>
  
  <pre><code>$html = file_get_html("http://www.example.com/product-link.html");
  $result = $html-&gt;find('table[id=item_specification]');
  echo $result[0];
  </code></pre>
  
  <p>That works without problem.
  Now I need to <strong>"dynamize"</strong> this process through a search submitted in an input form:</p>
  
  <pre><code>&lt;FORM method="post" action="http://www.example.com/search.html"&gt;
      &lt;input type="text" autocomplete="off" value="" name="search-field" id="header-search-field"&gt;
      &lt;button type="submit"&gt;Search&lt;/button&gt;
  &lt;/FORM&gt;
  </code></pre>
  
  <p>After submitted the input text form, it redirect me to another page, for example:</p>
  
  <pre><code>http://www.example.com/product-link-5.html
  </code></pre>
  
  <p>Now the result link, should be inserted in the <code>file_get_html($result_link_searched)</code> and used to perform the operations to find the <code>item_specification table</code> like above.</p>
