我为wordpress编写的一个短代码有问题。我试图使用get_the_content()函数，但它不是拉取我创建的自定义帖子类型的内容，而是拉取短代码所在页面的内容。其他函数都很好，例如get_the_title()和g et_the_post_thumbnail()。我在函数中传递ID，它对其他一切都很有效，只是不适用于get_the_content。
get_the_content($testimonial_item->ID);
短代码包含分页和其他元素，它们都能正常工作，只是这一个函数让我很难过。完整的代码如下，如有任何帮助，我们将不胜感激。
function ncweb_display_testimonial_items($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' );
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);
然后你就会得到你想要的东西。
当在内容中使用短代码时，您可以尝试使用此代码来获得完美的输出。
<?php
ob_start();
the_content();
$content_output = ob_get_clean();
echo $content_output;
?>使用短代码输出内容的最干净的方法是：
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');
