Related post widget after each blogger post

Posted bytenraj
I have been looking how to add related post after each of my post and finally, I am able to do it as you can see. If you are the one who has doesn't have related posts widget in your blog and want to add it in your blog then here is tutorial how to install this related posts widget to your blog.


Step 1: Go do Design>Edit Html

Step 2: I recommend you to download and save full template.

Step 3:Check the 'Expand Widget Templates' check box and press crtl+f to find the following code
   ]]></b:skin>  


Step 4: Just  before the above code, copy and paste the following css codes
 #related-posts {
float : left;
width : 540px;
margin-top:20px;
margin-left : 5px;
margin-bottom:20px;
font : 11px Verdana;
margin-bottom:10px;
}
#related-posts .widget {
list-style-type : none;
margin : 5px 0 5px 0;
padding : 0;
}
#related-posts .widget h2, #related-posts h2 {
color : #940f04;
font-size : 20px;
font-weight : normal;
margin : 5px 7px 0;
padding : 0 0 5px;
}
#related-posts a {
color : #054474;
font-size : 11px;
text-decoration : none;
}
#related-posts a:hover {
color : #054474;
text-decoration : none;
}
#related-posts ul {
border : medium none;
margin : 10px;
padding : 0;
}
#related-posts ul li {
display : block;
background : url(&amp;quot;http://4.bp.blogspot.com/_v5IxGTiMTD8/S86tvMfnwNI/AAAAAAAABCo/L5mp8kwzf0I
/s400/listarrow.png&amp;quot;) no-repeat 0 0;
margin : 0;
padding-top : 0;
padding-right : 0;
padding-bottom : 1px;
padding-left : 16px;
margin-bottom : 5px;
line-height : 2em;
border-bottom:1px dotted #cccccc;
}

Step 5: Now search for <head> tag and add the below script before it.

<script type='text/javascript'>
//<![CDATA[
var relatedTitles = new Array();
var relatedTitlesNum = 0;
var relatedUrls = new Array();
function related_results_labels(json) {
for (var i = 0; i < json.feed.entry.length; i++) {
var entry = json.feed.entry[i];
relatedTitles[relatedTitlesNum] = entry.title.$t;
for (var k = 0; k < entry.link.length; k++) {
if (entry.link[k].rel == 'alternate') {
relatedUrls[relatedTitlesNum] = entry.link[k].href;
relatedTitlesNum++;
break;
}
}
}
}
function removeRelatedDuplicates() {
var tmp = new Array(0);
var tmp2 = new Array(0);
for(var i = 0; i < relatedUrls.length; i++) {
if(!contains(tmp, relatedUrls[i])) {
tmp.length += 1;
tmp[tmp.length - 1] = relatedUrls[i];
tmp2.length += 1;
tmp2[tmp2.length - 1] = relatedTitles[i];
}
}
relatedTitles = tmp2;
relatedUrls = tmp;
}
function contains(a, e) {
for(var j = 0; j < a.length; j++) if (a[j]==e) return true;
return false;
}
function printRelatedLabels() {
var r = Math.floor((relatedTitles.length - 1) * Math.random());
var i = 0;
document.write('<ul>');
while (i < relatedTitles.length && i < 20) {
document.write('<li><a href="' + relatedUrls[r] + '">' + relatedTitles[r] + '</a></li>');
if (r < relatedTitles.length - 1) {
r++;
} else {
r = 0;
}
i++;
}
document.write('</ul>');
}
//]]>
</script>

Step 6: Once more find  <data:post.body/>,   immediately after this, paste the following code

<!--RELATED-POSTS-STARTS--><b:if cond='data:blog.pageType == &quot;item&quot;'>
<div id='related-posts'>
<font face='Arial' size='3'><b>Related Posts: </b></font><font color='#FFFFFF'><b:loop values='data:post.labels' var='label'><b:if cond='data:label.isLast != &quot;true&quot;'>,</b:if><b:if cond='data:blog.pageType == &quot;item&quot;'>
<script expr:src='&quot;/feeds/posts/default/-/&quot; + data:label.name + &quot;?alt=json-in-script&amp;callback=related_results_labels&amp;max-results=5&quot;' type='text/javascript'/></b:if></b:loop> </font>
<script type='text/javascript'> removeRelatedDuplicates(); printRelatedLabels();
</script></div></b:if><!--RELATED-POSTS-STOPS-->

Step 7: Edit the number in red in above codes( max-results=5) to show how many related posts you want to show.
