Add Related Post Widget to Blogger-For Original Templates

I found this tip in this site.

1.Log in to your dashboard--> layout- -> Edit HTML

2.Click on "Expand Widget Templates"

3.Scroll down to where you see this:

<div class='post-body entry-content'> <data:post.body/> <div style='clear: both;'/> <!-- clear for photos floats --> </div>

4.Copy below code and paste it immediately  after the line  <data:post.body/>

<b:if cond='data:blog.pageType == "item"'> <div class='similiar'> <div class='widget-content'> <h3>Related Posts :</h3> <div id='data2007'/><br/><br/> <script type='text/javascript'> var homeUrl3 = &quot;<data:blog.homepageUrl/>&quot;; var maxNumberOfPostsPerLabel = 4; var maxNumberOfLabels = 10; maxNumberOfPostsPerLabel = 100; maxNumberOfLabels = 3; function listEntries10(json) { var ul = document.createElement(&#39;ul&#39;); var maxPosts = (json.feed.entry.length &lt;= maxNumberOfPostsPerLabel) ? json.feed.entry.length : maxNumberOfPostsPerLabel; for (var i = 0; i &lt; maxPosts; i++) { var entry = json.feed.entry[i]; var alturl; for (var k = 0; k &lt; entry.link.length; k++) { if (entry.link[k].rel == &#39;alternate&#39;) { alturl = entry.link[k].href; break; } } var li = document.createElement(&#39;li&#39;); var a = document.createElement(&#39;a&#39;); a.href = alturl; if(a.href!=location.href) { var txt = document.createTextNode(entry.title.$t); a.appendChild(txt); li.appendChild(a); ul.appendChild(li); } } for (var l = 0; l &lt; json.feed.link.length; l++) { if (json.feed.link[l].rel == &#39;alternate&#39;) { var raw = json.feed.link[l].href; var label = raw.substr(homeUrl3.length+13); var k; for (k=0; k&lt;20; k++) label = label.replace(&quot;%20&quot;, &quot; &quot;); var txt = document.createTextNode(label); var h = document.createElement(&#39;b&#39;); h.appendChild(txt); var div1 = document.createElement(&#39;div&#39;); div1.appendChild(h); div1.appendChild(ul); document.getElementById(&#39;data2007&#39;).appendChild(div1); } } } function search10(query, label) { var script = document.createElement(&#39;script&#39;); script.setAttribute(&#39;src&#39;, query + &#39;feeds/posts/default/-/&#39; + label + &#39;?alt=json-in-script&amp;callback=listEntries10&#39;); script.setAttribute(&#39;type&#39;, &#39;text/javascript&#39;); document.documentElement.firstChild.appendChild(script); } var labelArray = new Array(); var numLabel = 0; <b:loop values='data:posts' var='post'> <b:loop values='data:post.labels' var='label'> textLabel = &quot;<data:label.name/>&quot;; var test = 0; for (var i = 0; i &lt; labelArray.length; i++) if (labelArray[i] == textLabel) test = 1; if (test == 0) { labelArray.push(textLabel); var maxLabels = (labelArray.length &lt;= maxNumberOfLabels) ? labelArray.length : maxNumberOfLabels; if (numLabel &lt; maxLabels) { search10(homeUrl3, textLabel); numLabel++; } } </b:loop> </b:loop> </script> </div> </div> </b:if>

5.Click on "Save Templates" and refresh your site.
