title: how to pass custom parameter in facebook sharer link
body: <p><strong>Code 1:</strong></p>
  
  <pre><code>&lt;a id="button" rel="nofollow" href="http://www.facebook.com/share.php?" onclick="return fbs_click()" target="_blank"&gt;
  &lt;script&gt;
      function fbs_click() {
          u=location.href;
          t=document.title;           
          window.open('http://www.facebook.com/sharer.php?u='+encodeURIComponent(u)+'&amp;t='+encodeURIComponent(t),
                  'sharer',
                  'toolbar=0,status=0,width=626,height=436');
  
              return false;
          }
  </code></pre>
  
  <p></p>
  
  <p>Here Title "t" is not working but i want to display custom <strong>title, summary, url and image</strong> so, I tried something like this </p>
  
  <p><strong>Code 2:</strong></p>
  
  <pre><code>&lt;a id="button"          href="http://www.facebook.com/sharer.php?
                          s=100
                          &amp;p[url]=&lt;?php echo $pressurl;?&gt;
                          &amp;p[images][0]=http://myurl/images/linkedin_image.png
                          &amp;p[title]=mytitle
                          &amp;p[summary]=containsummary                      "&gt; 
  </code></pre>
  
  <p>In both the cases nothing happened it automatically get some content (title,image,summary) from the above mentioned url and I want to display custom title,image and summary in facebook share page and i dono how to use og meta tag and <strong>what s=100 it means?</strong>..</p>
