我正在使用woocommerce 3.0.3，wordpress 4.7.3。
我创建了一个带有以下代码的自定义shortocde（参考默认[产品] woocommerce的短代码），但是分页不起作用，第2页变成空白。
<?php
add_shortcode('poster_products', 'poster_products');
if ( ! function_exists('poster_products') ){
function poster_products( $atts ) {
$atts = shortcode_atts( array(
'columns' => '4',
'orderby' => 'title',
'order' => 'asc',
'ids' => '',
'skus' => '',
'posts_per_page' => -1
), $atts, 'products' );
$query_args = array(
'post_type' => 'product',
'post_status' => 'publish',
'ignore_sticky_posts' => 1,
'orderby' => $atts['orderby'],
'order' => $atts['order'],
'posts_per_page' => $atts['posts_per_page'],
'paged' => max( 1, get_query_var( 'paged' ) ),
'post__in' => $atts['ids'],
//'meta_query' => WC()->query->get_meta_query(),
//'tax_query' => WC()->query->get_tax_query(),
);
if ( ! empty( $atts['skus'] ) ) {
$query_args['meta_query'][] = array(
'key' => '_sku',
'value' => array_map( 'trim', explode( ',', $atts['skus'] ) ),
'compare' => 'IN',
);
}
if ( ! empty( $atts['ids'] ) ) {
$query_args['post__in'] = array_map( 'trim', explode( ',', $atts['ids'] ) );
}
return poster_product_loop( $query_args, $atts, 'products' );
}
}
if ( ! function_exists('poster_product_loop') ){
function poster_product_loop( $query_args, $atts, $loop_name ) {
global $woocommerce_loop;
$columns = absint( $atts['columns'] );
$woocommerce_loop['columns'] = $columns;
$woocommerce_loop['name'] = $loop_name;
$query_args = apply_filters( 'woocommerce_shortcode_poster_product_query', $query_args, $atts, $loop_name );
$transient_name = 'wc_loop' . substr( md5( json_encode( $query_args ) . $loop_name ), 28 ) . WC_Cache_Helper::get_transient_version( 'product_query' );
$products = get_transient( $transient_name );
if ( false === $products || ! is_a( $products, 'WP_Query' ) ) {
$products = new WP_Query( $query_args );
set_transient( $transient_name, $products, DAY_IN_SECONDS * 30 );
}
ob_start();
if ( $products->have_posts() ) {
?>
<?php do_action( "woocommerce_shortcode_before_{$loop_name}_loop", $atts ); ?>
<?php woocommerce_product_loop_start(); ?>
<?php while ( $products->have_posts() ) : $products->the_post(); ?>
<?php wc_get_template_part( 'content', 'product' ); ?>
<?php endwhile; // end of the loop. ?>
<?php woocommerce_product_loop_end(); ?>
<?php do_action( "woocommerce_shortcode_after_{$loop_name}_loop", $atts ); ?>
<?php
do_action('woocommerce_pagination_after_poster_product_loop', $products);
} else {
do_action( "woocommerce_shortcode_{$loop_name}_loop_no_results", $atts );
}
woocommerce_reset_loop();
wp_reset_postdata();
do_action( 'woocommerce_after_shop_loop' );
return '<div class="woocommerce columns-' . $columns . '">' . ob_get_clean() . '</div>';
}
}
add_action('woocommerce_pagination_after_poster_product_loop', 'woocommerce_pagination_after_poster_product_loop');
if ( ! function_exists( 'woocommerce_pagination_after_poster_product_loop' ) ) {
function woocommerce_pagination_after_poster_product_loop($products) {
//wc_get_template( 'loop/pagination.php' );
if ( ! defined( 'ABSPATH' ) ) {
exit; // Exit if accessed directly
}
global $wp_query;
if ( $products->max_num_pages <= 1 ) {
return;
}
?>
<nav class="woocommerce-pagination">
<?php
echo paginate_links( apply_filters( 'woocommerce_pagination_args', array(
'base' => esc_url_raw( str_replace( 999999999, '%#%', remove_query_arg( 'add-to-cart', get_pagenum_link( 999999999, false ) ) ) ),
'format' => '?paged=%#%',
'add_args' => false,
'current' => max( 1, get_query_var( 'paged' ) ),
'total' => $products->max_num_pages,
'prev_text' => '←',
'next_text' => '→',
'type' => 'list',
'end_size' => 3,
'mid_size' => 3,
) ) );
} ?>
</nav>
<?php
}
分页创建网址结构，如/page/2/
第2页源代码显示
</nav>
<!DOCTYPE html>
和
if ( ! function_exists('poster_products') ){
echo var_dump(get_query_var( 'page' )); // ""
echo var_dump(get_query_var( 'paged' )); // ""
和
function poster_products( $atts ) {
return "poster_products getting called";
不返回任何内容，因此第2页没有调用poster_products。
答案 0 :(得分：0)
已经有一个多月了，但当时我已经完成了这段代码，现在对我有用。
