Question

我创建了自定义幻灯片后期类型。图像设置为每个新幻灯片的精选图片。我想在幻灯片模板中检索这些图像。

此幻灯片模板的HTML标记为：

<div class="wrapper">
<ul id="my-slider" class="my-slider">

<li>
<a href="http://www.flickr.com/photos/photo/123456" target="_blank"><img src="images/1.jpg" alt="image1"/></a>
<div class="my-description">
<h3>Image one</h3>
</div>
</li>

<li>
<a href="http://www.flickr.com/photos/photo/1234565" target="_blank"><img src="images/2.jpg" alt="image2"/></a>
<div class="my-description">
<h3>Image two</h3>
</div>
</li>


<li>
<a href="http://www.flickr.com/photos/photo/12345655" target="_blank"><img src="images/3.jpg" alt="image3"/></a>
<div class="my-description">
<h3>Image three</h3>
</div>
</li>

<li>
<a href="http://www.flickr.com/photos/photo/12345666" target="_blank"><img src="images/4.jpg" alt="image4"/></a>
<div class="my-description">
<h3>Image four oner</h3>
</div>
</li>
</ul>
</div>

这个HTML提供了四张幻灯片图像，因为我对其进行了硬编码。如何从wordpress自定义帖子类型动态检索附加图像以获得相同的结果？

Answer 1

为什么不简单地查询您的自定义帖子类型？一个例子：

<?php
$args = array('post_type' => 'your_custom_post_type');
query_posts( $args );

// the Loop
while (have_posts()) : the_post();
  //Do your stuff  

  //You can access your feature image like this:
  the_post_thumbnail();
endwhile;

Answer 2

Below is the example to retrive feature image. 

$args = array('post_type' => 'your_custom_post_type');
query_posts( $args );

// the Loop
while (have_posts()) : the_post();

if ( has_post_thumbnail() ) {

//Image size small,large or medium
  the_post_thumbnail('thumbnail',imagesize);?>


}
?>
endwhile;

我已经通过从自定义帖子类型中获取所有图像的数组并将其存储在变量$ myimage中来实现此功能。 $ myimage [0]是img标签的src，它需要捕获循环以获取所有图像

global $post;
$args = array(
'post_type' =>'slideshow',
'numberposts' => -1,
'orderby' => 'menu_order' );

$slider_posts = get_posts($args); ?>
<?php if($slider_posts) { ?>
<?php // start the loop
foreach($slider_posts as $post) : setup_postdata($post);
$myimage = wp_get_attachment_image_src(get_post_thumbnail_id(), 'full');
