How to Make Related Category Widget

Related Posts or as "the link that related", "article in the same category", "articles that mesh", "related post" or What is the name, the title is a related post and is usually displayed under the label naming (category), Related Post is the form of links that usually appear under a single post in the right column under the comments. The advantage with the related post, of course, will make it easier for visitors to our blog to find related articles without having to go and open the pages one by one in the link label.

Let’s make it now :

First Step#:

Copy code below

<b:if cond='data:blog.pageType == "item"'>
<div class='similiar'>

<div class='widget-content'>
<h3>Related Posts by Categories</h3>
<div id='data2007'/><br/><br/>
<script type='text/javascript'>

var homeUrl3 = "<data:blog.homepageUrl/>";
var maxNumberOfPostsPerLabel = 4;
var maxNumberOfLabels = 10;

maxNumberOfPostsPerLabel = 100;
maxNumberOfLabels = 3;

function listEntries10(json) {
var ul = document.createElement('ul');
var maxPosts = (json.feed.entry.length <= maxNumberOfPostsPerLabel) ?
json.feed.entry.length : maxNumberOfPostsPerLabel;
for (var i = 0; i < maxPosts; i++) {
var entry = json.feed.entry[i];
var alturl;

for (var k = 0; k < entry.link.length; k++) {
if (entry.link[k].rel == 'alternate') {
alturl = entry.link[k].href;
break;
}
}
var li = document.createElement('li');
var a = document.createElement('a');
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 < json.feed.link.length; l++) {
if (json.feed.link[l].rel == 'alternate') {
var raw = json.feed.link[l].href;
var label = raw.substr(homeUrl3.length+13);
var k;
for (k=0; k<20; k++) label = label.replace("%20", " ");
var txt = document.createTextNode(label);
var h = document.createElement('b');
h.appendChild(txt);
var div1 = document.createElement('div');
div1.appendChild(h);
div1.appendChild(ul);
document.getElementById('data2007').appendChild(div1);
}
}
}
function search10(query, label) {

var script = document.createElement('script');
script.setAttribute('src', query + 'feeds/posts/default/-/'
+ label +
'?alt=json-in-script&callback=listEntries10');
script.setAttribute('type', 'text/javascript');
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 = "<data:label.name/>";

var test = 0;
for (var i = 0; i < labelArray.length; i++)
if (labelArray[i] == textLabel) test = 1;
if (test == 0) {
labelArray.push(textLabel);
var maxLabels = (labelArray.length <= maxNumberOfLabels) ?
labelArray.length : maxNumberOfLabels;
if (numLabel < maxLabels) {
search10(homeUrl3, textLabel);
numLabel++;
}
}
</b:loop>
</b:loop>
</script>
</div>

</div>
</b:if>

Next Step#:

Now find this code ( Focus at Green Code)

<b:if cond='data:blog.pageType == "item"'>
<style>.fullpost{display:inline;}</style>
<p><data:post.body/></p>

<b:else/>
<style>.fullpost{display:none;}</style>
<p><data:post.body/>
<a expr:href='data:post.url'><strong>Read more...</strong></a></p>
</b:if>

Now put the first code like this

<b:if cond='data:blog.pageType == "item"'>
<style>.fullpost{display:inline;}</style>
<p><data:post.body/></p>

first code here

<b:else/>
<style>.fullpost{display:none;}</style>
<p><data:post.body/>
<a expr:href='data:post.url'><strong>Read more...</strong></a></p>
</b:if>

Then Save your setting.

well done , now you have the related post widget on your blog
