Vae Guide

<v:date_selection>

Renders a set of date links that represent the date range associated with a set of entries. This is commonly used to build archive sections for blogs that show posts by year, month, or day. The CSS class for the currently selected date range is set to current.

You may nest a <v:divider> tag inside this tag to specify a divider that is shown after each date link or after a certain number of date links. Dividers can also wrap the each dater link.

Required Attributes

  • path - path of the data to use to obtain the date range. If you set this to point to a collection of blog posts, only days, months, or years that have actual posts will be rendered.

  • date_field - name of the Date structure within each entry pointed to by path.

Optional Attributes

  • href - page to link to. Defaults to the current page.

  • param - URL parameter to contain the date value. Defaults to date.

  • strftime - provide a strftime format string in this attribute and it will be used to format the date displayed in the link as well as set the granularity of the date ranges. If you display a day value, links will be generated for each day there is an entry. If you display only a month and year, links will be generated for each month where there is an entry. If you display only a year, links will be generated for each year. In addition to the standard format parameters, Vae also supports a custom %N format string that includes the count of matching entries for this date range. Defaults to %B %Y which renders a link for each month in the format January 2009.

Sample Usage

<v:date_selection path="posts" date_field="date" />

Would render something like:

<a href="?date=2008-08">August 2008</a> <a href="?date=2008-07">July 2008</a>

Here’s how you would then display the post from the selected date range:

<v:collection path="posts[date=DATE($date)]">
</v:collection>
