I found I constantly needed a way for clients to mark a post as something they wanted to feature and I’ve never found sticky posts particularly inuitive and the UI is pretty hidden for new users. The simplest solution was a checkbox in prominently located metabox.
Please note that this plugin, by itself, will not change how your posts are displayed. It just gives the UI to users and a meta key to theme developers to query for.
Применение
This plugin simply adds a _featured meta key to every post with a value of yes for featured items and no for everything else. Actual display of the featured items is entirely up to the theme developer, but an example ( place in your template where you’d like to display a list of featured «Portfolios») might be as follows:
// params for our query
$args = array(
'post_type' => 'portfolio',
'posts_per_page' => 5,
'meta_key' => '_featured',
'meta_value' => 'yes'
);
// The Query
$featured_portfolios = new WP_Query( $args );
// The Loop
if ( $featured_portfolios ) :
echo '<ul class="featured">';
while ( $featured_portfolios->have_posts() ) :
$featured_portfolios->the_post();
echo '<li>' . get_the_title() . '</li>';
endwhile;
echo '</ul>';
else :
echo 'No featured portfolios found.';
endif;
/* Restore original Post Data
* NB: Because we are using new WP_Query we aren't stomping on the
* original $wp_query and it does not need to be reset.
*/
wp_reset_postdata();
Multiple queries per page load can slow down your site so it is worthwhile to take advantage of the Transients API, so an alternate usage would be:
// Get any existing copy of our transient data
if ( false === ( $featured_portfolios = get_transient( 'featured_portfolios' ) ) ) {
// It wasn't there, so regenerate the data and save the transient
// params for our query
$args = array(
'post_type' => 'portfolio',
'posts_per_page' => 5,
'meta_key' => '_featured',
'meta_value' => 'yes'
);
// The Query
$featured_portfolios = new WP_Query( $args );
// store the transient
set_transient( 'featured_portfolios', $featured_portfolios );
}
// Use the data like you would have normally...
// The Loop
if ( $featured_portfolios ) :
echo '<ul class="featured">';
while ( $featured_portfolios->have_posts() ) :
$featured_portfolios->the_post();
echo '<li>' . get_the_title() . '</li>';
endwhile;
echo '</ul>';
else :
echo 'No featured portfolios found.';
endif;
/* Restore original Post Data
* NB: Because we are using new WP_Query we aren't stomping on the
* original $wp_query and it does not need to be reset.
*/
wp_reset_postdata();
Then to ensure that your featured posts list is updated, add a function to your theme’s functions.php to delete the transient when a portfolio (in this example) post type is saved.
// Create a function to delete our transient when a portfolio post is saved
function save_post_delete_featured_transient( $post_id ) {
if ( 'portfolio' == get_post_type( $post_id ) )
delete_transient( 'featured_portfolios' );
}
// Add the function to the save_post hook so it runs when posts are saved
add_action( 'save_post', 'save_post_delete_featured_transient' );
Simple queries should only need the meta_key and meta_value parameters, but if you need something more advanced then you might want to read about how to use the more complex Meta Query parameters.
