Using Cookie Data For WP_Query Loop

Question

I'm trying to retrieve data set in a cookie and use this to run a query.

I've set the cookie in functions.php like so;

add_action( 'init', 'resultsCookie' );
function resultsCookie() {

   setcookie( 'your-results', '18,17,11,8,10,27,26', time() + 3600, COOKIEPATH, COOKIE_DOMAIN );
}

While I can echo the string, I can't seem to get this functioning within the query;

$cookie_array = $_COOKIE["your-results"];

// Test output              
echo $cookie_array;

$sug_args =  array(
  'post_type' => 'product',
  'post__in' => array( $cookie_array )
);

$sug_query = new WP_query ($sug_args);

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

  // Run Loop                   
  wc_get_template_part( 'content', 'product' ); 

endwhile; endif; wp_reset_query();

Any ideas?

What kind of data type is there in $_COOKIE["your-results"] ? If this is an array, you don't need to wrap this within array( $cookie_array ). Try (array) $cookie_array; instead. — Subharanjan

Just a string '18,17,11,8,10,27,26'. Strangely, it seems to pick out the first id just fine; for example '18'. However, the suggested tweak doesn't help unfortunately. — user2994718

You need to explode the comma separated string to get the array of IDs. Follow the below code.

$cookie_array = $_COOKIE["your-results"];

// Test output              
echo $cookie_array;

$cookie_array = array_map( 'absint', (array) explode(',', $cookie_array) );

$sug_args =  array(
  'post_type' => 'product',
  'post__in'  => $cookie_array,
);

$sug_query = new WP_query ($sug_args);

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

        // Run Loop                   
        wc_get_template_part( 'content', 'product' ); 

    endwhile; 
endif; 

wp_reset_query();
