    bhupen - Below is the working code. You need to check the size of the result.

     

    <#setting url_escaping_charset='ISO-8859-1'>
<div class="clearfix two-latest-post">
<#assign messages = rest("2.0","/search?q=" + "SELECT * FROM messages WHERE author.id='${user.id}' ORDER BY post_time DESC LIMIT 5"?url) />
		
		<#list messages.data.items as recent >
			<#if recent?has_content>
				<a href="${recent.view_href}">${recent.subject}</a><br/>
			</#if>   
			
		</#list>
		<br/>
	<#if messages.data.size &gt; 0> <!-- check the size of the response-->
		<a href="abc.com"><strong>See more Recent Posts</strong></a>
	</#if>
</div>

      VarunGrazitti  your code works with "View All links" but it doesn't work with post:

       

      I want to show "No Post Found" if there is no post:

      <#assign messages = rest("2.0","/search?q=" + "SELECT * FROM messages WHERE author.id='${user.id}' ORDER BY post_time DESC LIMIT 5"?url) />
		
		<#list messages.data.size &lt; 0>
			<#if recent>
				<a href="${recent.view_href}">${recent.subject}</a><br/>
      <#else>
                  No Post found
			</#if>   
			
		</#list>
		<br/>
	<#if messages.data.size &gt; 0> <!-- check the size of the response-->
		<a href="abc.com"><strong>See more Recent Posts</strong></a>
	</#if>
</div>

        bhupen - Try this one

         

        <#setting url_escaping_charset='ISO-8859-1'>
<div class="clearfix two-latest-post">
<#assign messages = rest("2.0","/search?q=" + "SELECT * FROM messages WHERE author.id='${user.id}' ORDER BY post_time DESC LIMIT 5"?url) />
	<#if messages.data.size &gt; 0> <!-- check the size of the response-->
		<#list messages.data.items as recent >
			<#if recent?has_content>
				<a href="${recent.view_href}">${recent.subject}</a><br/>
			</#if>   
			
		</#list>
		<br/>
	
		<a href="abc.com"><strong>See more Recent Posts</strong></a>
	<#else>	
		No Posts Found
	</#if>
</div>
