我一直在关注使用quicksand.js进行过滤动画的投资组合的许多教程。在函数中，我可以创建带有slugs的过滤器（类别）。经过无休止的阅读后，我无法弄清楚如何只显示某个过滤器的缩略图。
我已经从functions.php
我知道这是很多代码，但这是最后的手段。我无法让它工作，所以我希望一些php / wordpress大师可能会指出我错过的东西。
通过阅读，我确实设法通过使用以下方式拉出“特色”中发布的精选图片：
<?php
$args = array(
'post_type' => 'portfolio',
'tax_query' => array(
array(
'taxonomy' => 'filter',
'field' => 'slug',
'terms' => 'featured'
)
)
);
$query = new WP_Query( $args );
?>
然而，这只是拉出图像和它的标题，没有我需要的格式化HTML。但是将它应用到我已经使用过的东西是我完全迷失的地方。
提前致谢。

我不确定你在这做什么，但改变了这个
<?php
$large_image = wp_get_attachment_image_src( get_post_thumbnail_id(get_the_ID()), 'fullsize', false, '' );
$large_image = $large_image[0];
?>
到这个
<?php
$large_images[] = wp_get_attachment_image_src( get_post_thumbnail_id(get_the_ID()), 'fullsize', false, '' );
$large_image = $large_images[0];
?>

我找到了解决方案：
<?php
$args = array(
'post_type' => 'project',
'tax_query' => array(
array(
'taxonomy' => 'filter',
'field' => 'slug',
'terms' => 'featured'
)
)
);
$query = new WP_Query( $args );
?>

这是我用来获取附加图像的完整图像和拇指的代码：
$args = array(
'order' => 'ASC',
'post_mime_type' => 'image',
'post_parent' => $post->ID,
'post_status' => null,
'post_type' => 'attachment',
);
$upload_dir = wp_upload_dir();
$upload_url = $upload_dir['baseurl'];
// Get img data
$attachments = get_children( $args );
$images = array();
// Loop through attached images and get thumb + large img url
foreach($attachments as $attachment) {
$image_attributes = wp_get_attachment_image_src( $attachment->ID, 'thumbnail' );
$img['thumb'] = $image_attributes[0];
$image_attributes = wp_get_attachment_image_src( $attachment->ID, 'large' );
$img['large'] = $image_attributes[0];
array_push($images,$img);
}
// Get the image that you have set as the featured image in the post
$featured_img = wp_get_attachment_url(get_post_thumbnail_id($post->ID));
$featured_img_thumb = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'thumbnail' );
