我刚刚开始使用短代码，由于缺乏php知识，我无法想出如何在不使用php echo的情况下使用此短代码。
有人能帮我修改代码吗？
// SPONSORS Shorcode
function sponsors_shortcode($atts) {
extract(shortcode_atts(array(
"name" => "sponsors",
), $atts));
$args = array(
"post_type" => "sponsors",
"name" => $name,
);
$query = new WP_Query($args);
if($query->have_posts()) : while($query->have_posts()) : $query->the_post();
if(get_field(\'group\')) {
echo "<ul class=\'sponsors\'><h2>" , the_title() , "</h2>";
while(has_sub_field(\'group\')) {
$attachment_id = get_sub_field(\'image\');
$size = \'sponsorimage\';
$image = wp_get_attachment_image_src( $attachment_id, $size , false );
$link = get_sub_field(\'link\');
echo "<li>";
echo "<a href=\'" , $link , "\' target=\'_blank\'>";
echo "<img src=\'" , $image[0] , "\' />";
echo "</a>";
echo "</li>";
}
echo "</ul>";
}
endwhile; endif; wp_reset_query();
}
add_shortcode("sponsors", "sponsors_shortcode");

“echo”语句在shortcode函数中不起作用。shortcode函数只是返回变量；因此，您的代码如下所示：
if(get_field(\'group\')) {
$html = \'\';
$html.= "<ul class=\'sponsors\'><h2>" , get_the_title() , "</h2>";
while(has_sub_field(\'group\')) {
$attachment_id = get_sub_field(\'image\');
$size = \'sponsorimage\';
$image = wp_get_attachment_image_src( $attachment_id, $size , false );
$link = get_sub_field(\'link\');
$html.= "<li>";
$html.= "<a href=\'" , $link , "\' target=\'_blank\'>";
$html.= "<img src=\'" , $image[0] , "\' />";
$html.= "</a>";
$html.= "</li>";
}
$html.= "</ul>";
}
endwhile; endif; wp_reset_query();
return $html;
