Wordpress 简码始终位于内容的顶部

Question

这个短代码总是在内容的顶部，无论它放在页面中的什么位置，我怎样才能让它显示在它的位置？我试图用之前帖子中描述的替换echo语句，但它破坏了脚本。return简码从每个产品属性术语中提取 1 个产品，然后显示产品图像和属性术语名称。function navigationProdFromEachLimit() {$factwpslug = "/charts/?fwp_chart_type=";$number = '5'; //LIMIT THE NUMBER OF RETURNED CHART TYPES$args = array('number'     => $number,'orderby'    => 'count','order'      => 'DESC','hide_empty' => false,'include'    => $ids,);$product_categories = get_terms( 'pa_chart-type', $args ); $count = count($product_categories);if ( $count > 0 ){foreach ( $product_categories as $product_category ) {    $args = array(        'posts_per_page' => 1,        'tax_query' => array(            'relation' => 'AND',            array(                'taxonomy' => 'pa_chart-type',                'field' => 'slug',                'terms' => $product_category->slug            )        ),        'post_type' => 'product',        'orderby' => 'title,'    );    $products = new WP_Query( $args );    while ( $products->have_posts() ) {        $products->the_post();        ?>            <div class ="chart-type-nav <?php echo $product_category->slug ?>">                <a class="nav-thumb" href="<?php echo $factwpslug  . $product_category->slug ?>">                   <div class ="img-contain"> <?php the_post_thumbnail(); ?></div>                </a>                  <?php             echo '<span class="nav-title"><a href="'.$factwpslug  . $product_category->slug . '">' . $product_category->name . '</a></span>'; ?>            </div>        <?php    }}}}add_shortcode('navprodealimit', 'navigationProdFromEachLimit');

Answer 1

如果没有输出缓冲，您将无法回显短代码输出。您必须RETURN使用简码输出。

function navigationProdFromEachLimit() {

$factwpslug = "/charts/?fwp_chart_type=";

$number = '5'; //LIMIT THE NUMBER OF RETURNED CHART TYPES

$args = array(

'number'     => $number,

'orderby'    => 'count',

'order'      => 'DESC',

'hide_empty' => false,

'include'    => $ids,

);

$product_categories = get_terms( 'pa_chart-type', $args );

$count = count($product_categories);

ob_start(); // Use Output Buffering for your shortcode

if ( $count > 0 ){

foreach ( $product_categories as $product_category ) {

    $args = array(

        'posts_per_page' => 1,

        'tax_query' => array(

            'relation' => 'AND',

            array(

                'taxonomy' => 'pa_chart-type',

                'field' => 'slug',

                'terms' => $product_category->slug

            )

        ),

        'post_type' => 'product',

        'orderby' => 'title,'

    );

    $products = new WP_Query( $args );

    while ( $products->have_posts() ) {

        $products->the_post();

        ?>

            <div class ="chart-type-nav <?php echo $product_category->slug ?>">

                <a class="nav-thumb" href="<?php echo $factwpslug  . $product_category->slug ?>">

                   <div class ="img-contain"> <?php the_post_thumbnail(); ?></div>

                </a>

                  <?php

             echo '<span class="nav-title"><a href="'.$factwpslug  . $product_category->slug . '">' . $product_category->name . '</a></span>';

 ?>

            </div>

        <?php

            }

        }

    }

    return ob_get_clean(); // You have to return shortcode output.

}

add_shortcode('navprodealimit', 'navigationProdFromEachLimit');
