如何從自定義帖子類型檢索精選圖片？

Question

我已創建自定義幻燈片帖子類型。圖像設置爲每個新幻燈片帖子的精選圖像。我想要在幻燈片模板中檢索這些圖像。這個幻燈片模板

HTML標記是：

<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> 

此HTML提供了四個滑動圖片爲我硬編碼it.How從WordPress的自定義後類型動態檢索附加的圖像得到同樣的結果呢？

Answer 1

我已經讓所有的圖像陣列從自定義後類型並將其存儲在變量$ MYIMAGE實現這一點。 $ MYIMAGE [0]是img標籤這就需要在循環趕上來獲取所有圖像

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'); 

Answer 2

爲什麼不簡單地查詢您的自定義帖子類型？舉個例子：

<?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 3

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;
