由于某种原因，我的三元运算符分配不适用于数组的第二部分。有人看到我做错了什么吗？它应该只是查看永久链接字段是否有值，如果没有则插入link_url进入数组。
function getSiteMap()
{
$this->db->select('site_menu_structures_links.id, site_menu_structures_links.link_name');
$this->db->from('site_menu_structures_links');
$this->db->where('site_menu_structures_links.status_id', 1);
$this->db->where('site_menu_structures_links.is_category', 'Yes');
$this->db->order_by('site_menu_structures_links.sort_order');
$catQuery = $this->db->get();
if ($catQuery->num_rows())
{
foreach ($catQuery->result() as $cats)
{
// Set the Main Category into the array
$testArray[$cats->id] = array(
'id' => $cats->id,
'name' =>$cats->link_name
);
$this->db->select('site_content_pages.permalink, site_menu_structures_links_children.id, site_menu_structures_links_children.link_url, site_menu_structures_links_children.link_name');
$this->db->from('site_menu_structures_links_children');
$this->db->join('site_content_pages', 'site_content_pages.id = site_menu_structures_links_children.site_content_pages_id');
$this->db->where('site_menu_structures_links_id', $cats->id);
$this->db->where('site_menu_structures_links_children.status_id', 1);
$this->db->order_by('site_menu_structures_links_children.sort_order');
$childrenQuery = $this->db->get();
if ($childrenQuery->num_rows())
{
foreach ($childrenQuery->result() as $child)
{
$testArray[$cats->id]['children'][$child->id] = array(
'linke_url' => (empty($child->permalink)) ? $child->link_url : $child->permalink,
'link_name' => $child->link_name,
);
}
}
}
}
return $testArray;
}
EDIT:
也不是说社交阵列中应该有 3 个项目，但它并没有说有。我想知道这是否与该连接有关。这是我的输出：
Array
(
[2] => Array
(
[id] => 2
[name] => Roster
[children] => Array
(
[1] => Array
(
[linke_url] =>
[link_name] => Superstars
)
[2] => Array
(
[linke_url] =>
[link_name] => Champions and Contenders
)
[3] => Array
(
[linke_url] =>
[link_name] => Title History
)
)
)
[3] => Array
(
[id] => 3
[name] => Events
[children] => Array
(
[4] => Array
(
[linke_url] =>
[link_name] => Preview Next Event
)
[5] => Array
(
[linke_url] =>
[link_name] => Latest Event Results
)
[6] => Array
(
[linke_url] =>
[link_name] => Event Archives
)
[7] => Array
(
[linke_url] =>
[link_name] => Schedule An Event
)
)
)
[4] => Array
(
[id] => 4
[name] => Media
[children] => Array
(
[8] => Array
(
[linke_url] =>
[link_name] => Photo Gallery
)
)
)
[5] => Array
(
[id] => 5
[name] => Social
)
)
你有：
'linke_url' => (empty($child->permalink)) ? $child->link_url : $child->permalink,
我假设你的意思是'link_url'并不是'linke_url'，所以看起来您正在尝试执行以下操作：
If $child->permalink为空，设置'link_url' to $child->link_url，但是，如果$child->permalink不为空，已设置'link_url' to $child->permalink.
我建议使用简写版本三元运算符 ?: http://www.php.net/manual/en/language.operators.comparison.php#language.operators.comparison.ternary其形式为：$a = $b ?: $c这就像$b评估为true，即如果$b有任何价值，$a = $b， 否则$a = $c。为你：
'link_url' => $child->permalink ?: $child->link_url
If $child->permalink有一个值，将被使用，否则，值$child->link_url将会被使用。祝你好运！
