Display posts of the last 7 days

Question

I'm trying to display the 5 best rated posts of the last week (7 days) on my website, however I can't seem to figure out how to display them.

Here's what I've achieved so far but it doesn't seem to work:

<?php $slider_query = new WP_Query('posts_per_page=5&cat=3&orderby=highest_rated&order=desc'); ?>

<?php

$mylimit = 7 * 86400; //days * seconds per day

while ($slider_query->have_posts()) : $slider_query->the_post();

    $post_age = date('U') - get_post_time('U');

    if ($post_age < $mylimit) { 
?>

//The Post

<?php } ?>

<?php endwhile;?>

Answer 1

In addition to birgire's solution, as of WordPress 3.7, you can use Date parameters.

Your arguments would look like this to filter posts from the last 7 days:

$args = array(
    'post_type' => 'post',
    'post_status' => 'publish',
    'orderby' => 'date',
    'order' => 'DESC',

    // Using the date_query to filter posts from last week
    'date_query' => array(
        array(
            'after' => '1 week ago'
        )
    )
);

I think this must have been solved many times here on WordPress Answers.

You could also check out the examples in the Time parameters part in Codex for WP_Query.

Here are two of them (slightly modified to your needs)

Example 1:

// Create a new filtering function that will add our where clause to the query
function filter_where( $where = '' ) {
    // posts in the last 7 days
    $where .= " AND post_date > '" . date('Y-m-d', strtotime('-7 days')) . "'";
    return $where;
}

add_filter( 'posts_where', 'filter_where' );
$slider_query = new WP_Query('posts_per_page=5&cat=3&orderby=highest_rated&order=desc');    
remove_filter( 'posts_where', 'filter_where' );

Example 2:

// Create a new filtering function that will add our where clause to the query
function filter_where( $where = '' ) {
    // posts for May 1 to March 8, 2013
    $where .= " AND post_date >= '2013-05-01' AND post_date < '2013-05-8'";
    return $where;
}

add_filter( 'posts_where', 'filter_where' );
$slider_query = new WP_Query('posts_per_page=5&cat=3&orderby=highest_rated&order=desc');
remove_filter( 'posts_where', 'filter_where' )

assuming that you have this orderby=highest_rated covered with some plugin as you describe in the comment above.

Answer 3

From the WP_Query Time Parameters section:

Returns posts for just the current week:

$week = date('W');
$year = date('Y');
$query = new WP_Query( 'year=' . $year . '&w=' . $week );

Working for me like this, to show post from last 7 days according to the number of views and order by post views count DESC.

                $date_range = strtotime ( '-7 day' );  
                $args = array(
                    'post_type'         => 'post',
                    'post_status'       => 'publish',
                    'posts_per_page'    => '10',
                    'meta_key'          => 'post_views_count',
                    'orderby'           => 'meta_value_num',
                    'order'             => 'DESC', 
                    'date_query'        => array(
                        array(
                            'after' => array(
                                'year'  => date('Y', $date_range ),
                                'month' => date('m', $date_range ),
                                'day'   => date('d', $date_range ),
                            ),
                        )
                    )
                );


                $query = new WP_Query( $args );

Answer 5

you can simply use wp_get_archives()

 wp_get_archives( array( 'type' => 'weekly', 'limit' => 1, 'show_post_count' => 'true' ,'format'=>'option') ); ?>
