Question

我想使用短代码显示自定义帖子

我的自定义帖子代码位于 -

/ 自定义帖子 /

add_action( 'init', 'create_post_type' );
function create_post_type() {
register_post_type( 'service_items',
array(
'labels' => array(
'name' => __( 'Service Items' ),
'singular_name' => __( 'Service Items' ),
'add_new' => __( 'Add New' ),
'add_new_item' => __( 'Add New Service Items' ),
'edit_item' => __( 'Edit Service Items' ),
'new_item' => __( 'New Service Items' ),
'view_item' => __( 'View Service Items' ),
'not_found' => __( 'Sorry, we couldn\'t find the Service Items you are looking for.' )
),
'public' => true,
'publicly_queryable' => true,
'exclude_from_search' => true,
'menu_position' => 14,
'has_archive' => false,
'hierarchical' => false,
'capability_type' => 'page',
'rewrite' => array( 'slug' => 'custompost_id' ),
'supports' => array( 'title', 'editor', 'custom-fields','thumbnail' )
)
);
}

短信代码如下 -

function service_item_shortcode() {
$args = array(
'post_type' => 'service_items',
'order' => 'DESC',
'posts_per_page'=> -1
);

$service_items = new WP_Query( $args );
if( $service_items->have_posts() ):
while ( $service_items->have_posts() ) : $service_items->the_post();
$service_output = '<div class="span3 serv">';
$service_output .='<div class="serv-img">' ; 
$service_output .=get_the_post_thumbnail( $service_items->post->ID, service-image) ; 
$service_output .='</div>'; 
$service_output .= '<h3>' . get_the_title() . '</h3> ';
$service_output .= '<p>' . get_the_content() . '</p> ';
$service_output .= '</div>';
endwhile;
endif;

return $service_output;
}

add_shortcode( 'service_item', 'service_item_shortcode' );

我想在每个页面上显示4个自定义帖子项目。但是当我把[service-item]短代码输出只显示1个帖子时。

我每页需要4个帖子。请帮忙。

您应该编写变量中所有帖子的输出，而不是在每次迭代时重置变量。为此，在循环之前定义一个空变量，并简单地将每个帖子的所有输出添加到其中。以下是适合您的更改代码（未经测试）：

function service_item_shortcode() {
    $service_output = '';

    $paged = !empty($_GET['service_item_page']) ? absint($_GET['service_item_page']) : 1;
    if (!$paged) {
        $paged = 1;
    }

    $args = array(
        'post_type' => 'service_items',
        'order' => 'DESC',
        'posts_per_page'=> 4,
        'paged' => $paged
    );
    $service_items = new WP_Query( $args );

    if( $service_items->have_posts() ):
        while ( $service_items->have_posts() ) : $service_items->the_post();
            $service_output .= '<div class="span3 serv">';
            $service_output .= '<div class="serv-img">' ; 
            $service_output .= get_the_post_thumbnail( get_the_ID(), 'service-image'); 
            $service_output .= '</div>'; 
            $service_output .= '<h3>' . get_the_title() . '</h3> ';
            $service_output .= '<p>' . get_the_content() . '</p> ';
            $service_output .= '</div>';
        endwhile;
    endif;

    if ($service_items->max_num_pages > 1) {
        $service_output .= '<div class="pagination">';
        for($i = 1; $i <= $service_items->max_num_pages; $i++) {
            $service_output .= '<a href="' . add_query_arg('service_item_page', $i) . '">' . $i . '</a> ';
        }
        $service_output .= '</div>';
    }

    wp_reset_postdata();

    return $service_output;
}

add_shortcode( 'service_item', 'service_item_shortcode' );
