ezPublish - fetch objects published between dates - ezpublish

Question

I need to fetch articles (or objects) published between "now" and "a month before". Code looks like this:
{def $date = currentdate()}
{def $day = currentdate()|datetime( 'custom', '%d' )}
{def $month = currentdate()|datetime( 'custom', '%m' )}
{def $year = currentdate()|datetime( 'custom', '%Y' )}
{def $fromDate = maketime(0,0,0,$month|dec(), $day, $year)}
{def $items = fetch(content, list, hash(
'parent_node_id', 10,
'attribute_filter', array('and',
array('article/publish_date', '<=', $data),
array('article/publish_date', '>', $fromDate),
array( 'priority', '>=', 0 )),
'class_filter_type', 'include',
'class_filter_array', array('article')
))}
Unfortunately, nothing comes out. When I remove the $fromDate array from the fetch, it works.

In short, your template fetch code is inaccurate (either here or in your template).
The line, "array('article/publish_date', '<=', $data)," should be "array('article/publish_date', '<=', $date)," instead to fix the variable typo.
Also your date timestamp comparison logic (operator) usage is also incorrect (I think). It has been a while since I last did what you are doing but when I did it last I used the following logic instead.
{* Example: http://example/layout/set/content_statistics.csv/(startDate)/2010-07-14/(endDate)/2010-07-19/ *}
{def $articles=false()}
{if and( is_set( $view_parameters.startDate ), is_set( $view_parameters.endDate ) )}
{def $startDate=$view_parameters.startDate|explode("-")
$endDate=$view_parameters.endDate|explode("-")}
{def $startDateTimestamp=maketime(0,0,0,$startDate.1,$startDate.2,$startDate.0)
$endDateTimestamp=maketime(23,59,59,$endDate.1,$endDate.2,$endDate.0)}
{set $articles=fetch( 'content', 'list', hash(
'parent_node_id', 77,
'class_filter_type', 'include',
'class_filter_array', array( 'article' ),
'sort_by', array( 'published', false() ),
'attribute_filter', array( array( 'published', '>=', $startDateTimestamp ),
array( 'published', '<', $endDateTimestamp ) )
) )}
{else}
{set $articles=fetch( 'content', 'list', hash(
'parent_node_id', 77,
'class_filter_type', 'include',
'class_filter_array', array( 'article' ),
'sort_by', array( 'published', false() ),
'limit', 10000
) )}
{/if}
Notice that the attribute filter date timestamp comparison operators use a very different formula, re: '>=' '<' and I think this example will work better for you.
'attribute_filter', array( array( 'published', '>=', $startDateTimestamp ),
array( 'published', '<', $endDateTimestamp ) )
) )}
I hope this helps!
