Sort products by most viewed

问题

I'm using a plugin that already count product views and store it in a table called 'mwb_wpr_data'.

The query to list the product views is:

SELECT DISTINCT('productid') FROM 'mwb_wpr_data' WHERE 'action' = 'view'

The productid field is a FK to Woocomerce products.

How can I modify the Woocommerce default sorting, so it will display products by order of most views based in the table 'mwb_wpr_data'?

Current code using the plugin Post View Counter:

add_action( 'pre_get_posts', 'my_view_filter' );
function my_view_filter($query){
    if ( 
        $query->is_main_query() && 
        ( $query->is_home() || $query->is_archive() || $query->is_search() )
    ) {
            $query->set('suppress_filters', 'false');
            $query->set('orderby', 'post_views');
            $query->set('order', 'DESC');
    }
}

According to me you have set the correct pre_get_post but problem is in your if condition.

You have set the current_user_can which not correct filter is for every user so if you are not login in with administrator role than your query will not work.

current_user_can('administrator')

Remove this above one from the condition.

add_action( 'pre_get_posts', 'my_view_filter' );
function my_view_filter($query){
    if ($query->is_main_query() && ( $query->is_home() || $query->is_archive() || $query->is_search() )
    ) {
            $query->set('suppress_filters', 'false');
            $query->set('orderby', 'post_views');
            $query->set('order', 'DESC');
    }
}

Ok, so the RIGHT way to do this would be

Change how your post view counts are stored, so that they are stored as postmeta of each product (post) in a field like _post_views_count.

Use meta_key & orderby in wp_query like this

$args = array(
    'meta_key' => '_post_views_count',
    'orderby' => 'meta_value_num',
    'order' => 'ASC'
);

< EDIT >

IF you want to use the same plugin for recording your product views, I'd set up a function that fires every time a post view is added to the table that updates a postmeta field of the product.

Is it elegant? No.

Will it work? Yes.

Not sure about the plugin you're using (it would be great if you give additional info about it) but I've been using Post Views Counter for years and it works really well.

It even has a query parameter for WP_Query (to query posts by post views):

EDIT: This query parameter won't work without the Post Views Counter plugin as it's not a WordPress default parameter.

More info about this plugin API here: https://dfactory.eu/docs/post-views-counter/developers-api/

$query_args = array(
    'posts_per_page'   => 12,
    'order'            => 'DESC',
    'suppress_filters' => false,  //required param
    'orderby'          => 'post_views',  //required param
);
$query      = new WP_Query( $query_args );

if ( $query->have_posts() ):
    while ( $query->have_posts() ): $query->the_post();

//Post content here
    echo get_the_title();

    endwhile;
endif;

I hope this helps, Cheers!

According to the plugins documentation you are required to pass the post_type as well in order for this to work, i.e.

$args = array(
    'order' => 'asc',
    'post_type' => 'event',
    // required by PVC
    'suppress_filters' => false,
    'orderby' => 'post_views',
    'fields' => ''
);
$most_viewed = get_posts( $args );

That code is in the post that @Marounm linked to in comment higher up.

Try passing the post_type arg as well i.e.

 $query->set('post_type', 'product');
