我已经编写了这个几乎可以正常工作的函数:
function all_animals() {
$categories = get_categories(array(
'echo' => 0,
'hide_empty' => 0,
'taxonomy' => 'species',
'hierarchical' => 1,
'show_count' => 0,
'depth' => 0
)); ?>
<ul>
<?php ob_start();
foreach ($categories as $cat) {
$cat_args = array(
'posts_per_page' => -1,
'post_type' => 'animal',
'showposts' => -1,
'post_status' => 'publish',
'cat' => $cat->cat_ID
);
$the_animals = new WP_Query($cat_args);
$animal_count = $the_animals->post_count;
?>
<li>
<a href="<?php echo get_category_link( $cat->cat_ID ); ?>">
<?php echo $cat->cat_name; ?>
<span class="count"><?php echo $animal_count; ?></span>
</a>
</li>
<?php
}
wp_reset_postdata();
$animal_list = ob_get_clean();
return $animal_list;
echo '</ul>';
}
...然后在这样的页面模板上使用它:
echo all_animals();
问题:唯一不起作用的是$animal_count
,它始终返回0。
我也尝试过...
global $wp_query;
$animal_count = $wp_query->found_posts;
...但这没什么区别。
我该如何解决?

您可以使用
pos = {
"x": 0,
"y": 0
}
while True:
n = input()
if not n:
break
direction,steps=n.split()
if direction == "UP":
pos["y"] += int(steps)
elif direction == "DOWN":
pos["y"] -= int(steps)
elif direction == "LEFT":
pos["x"] -= int(steps)
elif direction == "RIGHT":
pos["x"] += int(steps)
print (int(round((pos["x"]**2 + pos["y"]**2)**0.5)))
此处“ ID为类别ID

该解决方案比我想象的要容易:
$animal_count = $the_animals->count;
