事实证明，很难用税务查询配置我的快捷码。当我省略分类法/术语的参数时，我什么也没有得到。
这将按预期返回1篇文章
[loop post_type="website" taxonomy="industry" terms="beauty" posts="3"][/loop]
但是，当为分类法省略参数时，当我想取回所有网站帖子时，它不会返回帖子。
[loop post_type="website" posts="-1" ][/loop]
My shortcode函数
function loop_recent_posts_shortcode($atts) {
$tax_queries = array(
array (
\'taxonomy\' => $atts[\'taxonomy\'],
\'terms\' => array($atts[\'terms\']),
\'field\' => \'slug\'
)
);
$atts = shortcode_atts(
array(
\'posts\' => 6,
\'post_type\' => \'\',
\'taxonomy\' => \'\',
\'terms\' => \'\',
\'meta_key\' => \'\',
\'meta_value\' => 0,
), $atts);
$return_string = \'\';
$return_string .= \'<ul class = "work_loop">\';
$args = array(
\'post_type\' => $atts[\'post_type\'],
\'tax_query\' => $tax_queries,
\'orderby\' => \'date\',
\'order\' => \'DESC\',
\'meta_key\' => $atts[\'meta_key\'],
\'meta_value\' => $atts[\'meta_value\'],
\'showposts\' => $atts[\'posts\'],
);
$sc_query = new WP_Query( $args);
var_dump($sc_query);
if ($sc_query->have_posts()) :
while ($sc_query->have_posts()) : $sc_query->the_post();
//POST WITH THUMBNAIL
if (has_post_thumbnail($id)) {
$return_string .= \'<li><a href="\' . get_permalink();
$return_string .= \'"><span class = "icon more_icon"></span><img src = "\' . ml_get_thumbnail(null, \'3_col_folio\') . \'" alt = "websites"><span class = "triangle_up"></span><h2>\'.get_the_title().\'</h2></a></li>\';
} else {
//POST WITHOUT THUMBNAIL
$return_string .= \'<li><a href="\' . get_permalink();
$return_string .= \'"><h2>\'.get_the_title().\'</h2></a></li>\';
}
endwhile;
endif;
$return_string .= \'</ul>\';
wp_reset_query();

除了在设置了所有值后仅添加税务查询外，您只需确保设置了所有默认属性。
