get_the_content 在简码中不起作用

Question

我为 wordpress 编写的短代码有问题。 我正在尝试使用get_the_content()函数，但不是提取我创建的自定义帖子类型的内容，而是提取短代码所在页面的内容。 其他函数都工作正常，例如get_the_title()和et_the_post_thumbnail() 。 我在函数中传递了 ID，它适用于其他一切，只是不适get_the_content 。

get_the_content($testimonial_item->ID);

短代码包含所有正常工作的分页和其他元素，正是这一功能让我感到悲伤。 完整代码如下，任何帮助将不胜感激。

function ncweb_display_testimonial_items($atts, $content = null) {

extract( shortcode_atts( array(
    'per_page' => 6
), $atts ) );

/* pagination parameters */

// check what page we are on
if ( isset ($_GET['testimonial-page'] ) ) $page = $_GET['testimonial-page']; else $page = 1;

// default number of pages
$total_pages = 1;

// portfolio offset. Used in the get_posts() query to show only portfolio for the current page
$offset = $per_page * ($page-1);

// setup the portfolio args for retrieving the total number of portfolio items
$testimonial_count_args = array(
    'post_type' => 'ncweb-testimonials',
    'posts_per_page' => -1
);
$testimonial_count = count(get_posts($testimonial_count_args));

// calculate the total number of pages
$total_pages = ceil($testimonial_count/$per_page);

/* end pagination parameters */

// main image query
$testimonial_args = array(
    'post_type' => 'ncweb-testimonials',
    'numberposts' => $per_page,
    'offset' => $offset
);

$testimonial_items = get_posts($testimonial_args);

// start our output buffer
ob_start();

if($testimonial_items) :

    /*** main portfolio loop ***/

        $counter = 1;
        echo '<div class="testimonial-items" id="testimonial-items">';

        foreach($testimonial_items as $testimonial_item) :

        $testimonial_company = get_post_meta($testimonial_item->ID, 'ncweb_testimonial_company', true);
        $testimonial_client = get_post_meta($testimonial_item->ID, 'ncweb_testimonial_client_name', true);

        echo '<aside class="testimonial-list-item row">';
        echo '<div class="col-xs-12 testimonial-list-item-info">';
        echo '<div class="testimonial-image">'. get_the_post_thumbnail($testimonial_item->ID) .'</div>';
        echo '<div class="testimonial-client"><span class="testimonial-client-name">'. $testimonial_client .'</span><br/><span class="testimonial-company">'. $testimonial_company .'</span></div>';
        echo '</div>'; //end of testimonial-list-item-info
        echo '<div class="col-xs-12 testimonial-item-content">'. get_the_content($testimonial_item->ID); .'</div>';
        echo '</aside>';

        $counter++;

        endforeach;
        echo '</div>';

        /*** display pagination ***/

        // pagination base
        echo '<div id="testimonial-pagination">';

            $base = get_permalink(get_the_ID()) . '%_%';

            echo paginate_links( array(
                'base' => $base,
                'format' => '?testimonial-page=%#%',
                'prev_text' => __('Previous', 'ncweb'),
                'next_text' => __('Next', 'ncweb'),
                'total' => $total_pages,
                'current' => $page,
                'end_size' => 1,
                'mid_size' => 5
            ));

        echo '</div>';

    /*** end pagination display ***/


else :
    echo '<p>' . __('No testimonial items found.', 'ncweb') . '</p>';
endif; // end if($images)

return ob_get_clean();

}
add_shortcode( 'testimonial-items', 'ncweb_display_testimonial_items' );

Answer 1

这是因为get_the_content()函数是一个包装器，它的唯一参数是Read More文本和stripteaser参数。

你真正想要的是。

$post= get_post($testimonial_item->ID);
$testimonial_items = $post->content ;
$testimonial_items = apply_filters('the_content', $testimonial_items);

然后，您将拥有您正在寻找的东西。

Answer 2

在内容中使用短代码时，您可以尝试使用此代码以获得完美的输出。

 <?php ob_start(); the_content(); $content_output = ob_get_clean(); echo $content_output; ?>

Answer 3

使用短代码输出 the_content 的最简洁方法是：

function my_sc_content() {
    ob_start();
        $my_content = the_content();
        echo $my_content;
        $output_string = ob_get_contents();
    ob_end_clean();
    return $output_string;
}

add_shortcode('my-content','my_sc_content');
