Filter posts within last month

Hello,

I have the following Macro:

<xsl:template match="/">

  <xsl:for-each select="$currentPage/ancestor-or-self::umbBlog//umbBlogPost">            
    <xsl:sort select="count(BlogLibrary:GetCommentsForPost(@id)//comment)" data-type="number" order="descending" />       
      <xsl:if test="position()&lt; 5">
        <xsl:variable name="text" select="umbraco.library:StripHtml($currentPage/@nodeName)" />            
            <a href="{umbraco.library:NiceUrl(@id)}" class="popularPostsClass"><xsl:value-of select="./@nodeName" disable-output-escaping="yes"/></a>
            <br/>
      </xsl:if>   
  </xsl:for-each>

I would like to apply what this macro does only to the posts within the last month. Is there any way I can surround this whole part with another sort that only reads the posts within the last month?

Thank you!

Hi Alexandru,

You should be able to use a predicate on your node selector to select only those articles within a certain range from today. Umbraco has some XSLT extension methods available to help with this, namely: FormatDateTime, CurrentDate and DateDiff. It should allow you to do something like this (not tested!):

<!-- Get current date -->
<xsl:variable name="currentDate" select="substring-before(umbraco.library:CurrentDate(), 'T')"/>

<!-- Add a predicate to node selection to get articles where the difference between blogPostDate property
 and currentDate variable is less than 43829 minutes(! which equates roughly to 1 month)  -->
<xsl:for-each select="$currentPage/ancestor-or-self::umbBlog//umbBlogPost[umbraco.library:DateDiff(umbraco.library:FormatDateTime(blogPostDate,'yyyy-MM-dd'), $currentDate, 'm') < 43829]">            
    <xsl:sort select="count(BlogLibrary:GetCommentsForPost(@id)//comment)" data-type="number" order="descending" />       
    <xsl:if test="position()< 5">
        <xsl:variable name="text" select="umbraco.library:StripHtml($currentPage/@nodeName)" />            
        <a href="{umbraco.library:NiceUrl(@id)}" class="popularPostsClass"><xsl:value-of select="./@nodeName" disable-output-escaping="yes"/></a>
        <br/>
    </xsl:if>   
</xsl:for-each>

Hopefully this gets you started...

Hi Dan,

For now I am using this:

<xsl:for-each select="$currentPage/ancestor-or-self::umbBlog//umbBlogPost">          
        <xsl:sort select="count(BlogLibrary:GetCommentsForPost(@id)//comment)" data-type="number" order="descending" />   
                <xsl:variable name="currentDate" select="umbraco.library:FormatDateTime(umbraco.library:CurrentDate(), 'dd-MM-yyyy')"/>
                <xsl:variable name="postDate" select="umbraco.library:FormatDateTime(umbraco.library:LongDate(./PostDate), 'dd-MM-yyyy')"/>
                <xsl:variable name="diffSeconds" select="umbraco.library:DateDiff($currentDate, $postDate, 's')"/>
                <xsl:variable name="diffDays" select="floor($diffSeconds div (60 * 60 * 24))"/>

                <xsl:choose>
                    <xsl:when test="$diffDays &lt; 31">
                        <li>
                            <a href="{umbraco.library:NiceUrl(@id)}" class="popularPostsClass"><xsl:value-of select="./@nodeName" disable-output-escaping="yes"/></a>
                            <br/>
                        </li>
                    </xsl:when>
                    <xsl:otherwise>
                    </xsl:otherwise>
                </xsl:choose>
    </xsl:for-each>

and I hide the rest that I don't need through CSS. but I will give your version a try as I would rather avoid having a huge list hidden by CSS. Thanks, I will get back to you with how it goes!

It is errorless but it seems the predicate won't work. Regardless of the number of minutes I put in, it still reads older posts.

Hi Alexandru,

There are quite a lot of things that can be done to help in debugging this, for example, try putting this inside your loop and see what it returns:
```
<xsl:value-of select="umbraco.library:DateDiff(umbraco.library:FormatDateTime(PostDate,'yyyy-MM-dd'), $currentDate, 'm')" />
```

It seems I am getting negative values. Let me try to fix that and see if there's any change.

Aye, fixed it. It should be '> [negative value of timespan]'

you should change this in your post so that others can have the right version too :)

It's this:
```
<xsl:for-each select="$currentPage/ancestor-or-self::umbBlog//umbBlogPost[umbraco.library:DateDiff(umbraco.library:FormatDateTime(umbraco.library:LongDate(./PostDate), 'dd-MM-yyyy'), $currentDate, 'm') &gt; -43829]">            
```

Ah okay, try this as the predicate in that instance:
```
[umbraco.library:DateDiff($currentDate, umbraco.library:FormatDateTime(PostDate,'yyyy-MM-dd'), 'm') &lt; 43829]
```
