所以我一直在尝试将字幕和链接集成到Nettuts上的Envato FlexSlider插件中。
http://wp.tutsplus.com/tutorials/create-a-responsive-slider-plugin-with-flexslider/
Adding caption area to 'Flexslider Plug-in' 不起作用。
这是envato-flexslider.php文件,其中发生了所有魔法。

至于添加外部链接到特色图像,我试图通过slider-img-type.php文件在我的自定义帖子类型中设置自定义字段,但是没有用。
感谢您的帮助, 达斯汀

好的,这就是我能够将链接和标题集成到FlexSlider中的方式。希望这能帮助任何一直像我一样挣扎的人。在envato-flexslider.php中,这是函数efs_get_slider()所需的内容。只需确保分别在幻灯片image_caption和image_link中命名自定义字段。
function efs_get_slider(){
$slider= '<div class="flexslider">
<ul class="slides">';
$efs_query= "post_type=slider-image";
$myposts = get_posts($efs_query);
foreach($myposts as $post) : setup_postdata($post);
$img= get_the_post_thumbnail( $post->ID, 'full' );
$slide_link= get_post_meta( $post->ID, 'image_link', true);
$slide_caption= get_post_meta( $post->ID, 'image_caption', true);
$slider.='<li><a href='.$slide_link.'>'.$img.'</a><p class="flex-caption">'.$slide_caption.'</p></li>';
endforeach;
$slider.= '</ul>
</div>';
return $slider;
}

所以基本上你可以在这里添加任何你想要的东西:
if (have_posts()) : while (have_posts()) : the_post();
$img= get_the_post_thumbnail( $post->ID, 'large' );
$slider.='<li>'.$img.'</li>';
endwhile; endif; wp_reset_query();
$slider.= '</ul>
</div>';
return $slider;
因此,假设您想添加一些自定义字段信息,那么您只需将变量设置为该信息,然后将其添加到滑块变量中。
if (have_posts()) : while (have_posts()) : the_post();
$img= get_the_post_thumbnail( $post->ID, 'large' );
$caption= get_post_meta($post->ID, 'custom_field', true); //get custom field
$slider.='<li>';
$slider.= $img;
$slider.= '<span>'.$caption.'</span>';
$slider.='</li>';
endwhile; endif; wp_reset_query();
$slider.= '</ul>
</div>';
return $slider;
但是,所有这一切都变得混乱。让我们简化一下,然后做一个正确的sprintf并将其包装成几行。
if (have_posts()) : while (have_posts()) : the_post();
$slider .= sprintf('<li>%1$s<span>%2$s</span></li>',
get_the_post_thumbnail( $post->ID, 'large' ),
get_post_meta($post->ID, 'custom_field', true)
);
endwhile; endif; wp_reset_query();
$slider.= '</ul>
</div>';
return $slider;
