    copied!<p>The basic solution (lazy too) could be dragging around all your possible parameters with empy values when not needed, so for example you would have:</p> <pre><code>&lt;ul class="archive"&gt; &lt;li&gt; &lt;div&gt;Year&lt;/div&gt; &lt;ul&gt; &lt;li&gt;&lt;a href="article.php?year=all&amp;category=&lt;?=$_GET['category']?&gt;"&gt;Every year&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="article.php?year=2013&amp;category=&lt;?=$_GET['category']?&gt;"&gt;2013&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="article.php?year=2012&amp;category=&lt;?=$_GET['category']?&gt;"&gt;2012&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="article.php?year=2011&amp;category=&lt;?=$_GET['category']?&gt;"&gt;2011&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="article.php?year=2010&amp;category=&lt;?=$_GET['category']?&gt;"&gt;2010&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;/ul&gt; &lt;ul class="archive"&gt; &lt;li&gt; &lt;div&gt;Category&lt;/div&gt; &lt;ul&gt; &lt;li&gt;&lt;a href="?category=all&amp;year=&lt;?=$_GET['year']?&gt;"&gt;General news&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="article.php?category=sport&amp;year=&lt;?=$_GET['year']?&gt;"&gt;Sport news&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="article.php?category=international&amp;year=&lt;?=$_GET['year']?&gt;"&gt;International news&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="article.php?category=national&amp;year=&lt;?=$_GET['year']?&gt;"&gt;National news&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;/ul&gt; </code></pre> <p>Anyway I reccomend that you build some sort of automatic menù generator, so you can add parameters and links without too much effort, for example via a "link generator" which will append the needed parameters (I'll put in a snippet for this if you need).</p>
