I started to work on one website after another developer and there is problem with his “popular widget” which is basically showing 3 random posts from category. There is some Switch statement which is regulating to show from category news 3 random post not older then 1 month and for other categories 3 month. I don’t understand what he did there with [‘interval’] but when I use wordpress time parameters still I don’t have results.
function getSomePost($category,$postsPerPage=3) {
global $post;
$args = array(
'category_name'=>$category,
'posts_per_page'=>$postsPerPage,
'post_type'=>'post',
'post_status'=>'publish',
'post__not_in'=>array($post->ID),
'orderby'=>'rand',
);
switch ($category)
{
case 'news':
$args['interval'] = '1 MONTH';
break;
case 'analysis':
$args['interval'] = '3 MONTH';
break;
case 'reports':
$args['interval'] = '3 MONTH';
break;
}
$query = new WP_Query($args);
if ( $query->have_posts() ) {
while ( $query->have_posts() ) {
$query->the_post();
$postThumbClass="no-thumb";
?>
<div <?php post_class(array('wp-post-entry', 'sidebar-post' )); ?>>
<?php if(has_post_thumbnail ()):?>
<?php $postThumbClass="" ?>
<div class="wp-post-thumbnail">
<a href="https://wordpress.stackexchange.com/questions/100099/<?php the_permalink() ?>">
<?php the_post_thumbnail(array(70,70)); ?>
</a>
</div>
<?php endif; ?>
<div class="wp-post-full-content <?php echo $postThumbClass ?> ">
<h3 class="wp-post-title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
<!--
<div class="post-content">
<?php the_excerpt() ?>
</div>
//-->
</div>
</div>
}
}
}
I was trying to replace inside switch
case 'news':
$args['interval'] = '1 MONTH';
break;
with
case 'news':
// Create a new filtering function that will add our where clause to the query
function filter_where( $where="" ) {
// posts in the last 30 days
$where .= " AND post_date > '" . date('Y-m-d', strtotime('-30 days')) . "'";
return $where;
}
add_filter( 'posts_where', 'filter_where' );
$query = new WP_Query( $args );
remove_filter( 'posts_where', 'filter_where' );
break;
and
case 'analysis':
$args['interval'] = '3 MONTH';
break;
with
case 'analysis':
// Create a new filtering function that will add our where clause to the query
function filter_where( $where="" ) {
// posts in the last 30 days
$where .= " AND post_date > '" . date('Y-m-d', strtotime('-90 days')) . "'";
return $where;
}
add_filter( 'posts_where', 'filter_where' );
$query = new WP_Query( $args );
remove_filter( 'posts_where', 'filter_where' );
break;
but it is not working I tried also to use if ($category == 'news')
but it breaks the site

You cannot declare multiple functions with same name in PHP. Codex examples for this are technical demonstration, rather than ready-made usable snippet.
Give your filter functions unique names, that are not likely to clash with your own or third party code.
