与父类别ID相关的子类别ID切换大小写

时间：2015-05-21 作者：niziou

我想切换页脚中的广告标签，具体取决于当前显示的类别。下面的代码适用于自定义类别页面和交换机机箱中包含的类别页面。我的代码寻找ID，问题是我有很多子类别，它们是我主要类别的子类别，因此这些类别的ID不同于父ID。

在不为每个儿童类别编写案例的情况下，我如何解决这个问题？

<?php
 $footer_ads=\'\';
 if(is_single())
    {
global $post;
$category = get_the_category($post->ID);
$cat_id_gum="";
if(($category[0]->parent)!=\'0\')
{
    $cat_id_gum=$category[0]->cat_ID;
}
elseif(($category[1]->parent)!=\'0\')
{
    $cat_id_gum=$category[1]->cat_ID;
}
elseif(($category[2]->parent)!=\'0\')
{
    $cat_id_gum=$category[2]->cat_ID;
}
else
{
    $cat_id_gum=$category[3]->cat_ID;
}

}

好啊此代码：

$cat_id_gum="";
if(($category[0]->parent)!=\'0\')
{
    $cat_id_gum=$category[0]->cat_ID;
}
elseif(($category[1]->parent)!=\'0\')
{
    $cat_id_gum=$category[1]->cat_ID;
}
elseif(($category[2]->parent)!=\'0\')
{
    $cat_id_gum=$category[2]->cat_ID;
}
else
{
    $cat_id_gum=$category[3]->cat_ID;
}
其实没有必要。过一会儿我会告诉你我的意思。但是，稍后，您可以设置$cat_id_gum 到当前帖子ID。。。

$cat_id_gum = get_the_ID();
。。。这没有任何意义，使前面的所有代码都毫无意义。你还做了一些对我来说毫无意义的事情。我将忽略这一点，尝试解决简化代码和处理子类别的基本问题。

首先，让我们将类别和代码关联起来：

// the key is the category
// the value is the gum code
$gum_codes = array(
  \'1\' => \'75803baa\',
  \'2\' => \'b737914c\'
);
现在你可以echo 脚本如下：

printf($script,$gum_codes[1]);
现在，您需要将类别转换为其最顶层的父类别：

$category = get_the_category($post->ID);
$cat_id_gum = $category[0]->cat_ID;
$cat_id_gum = get_ancestors($cat_id_gum,\'category\');
array_shift($cat_id_gum);
$cat_id_gum = $cat_id_gum[0];
// $cat_id_gum is now your parent category
把这些放在一起：

$category = get_the_category($post->ID);
$cat_id_gum = $category[0]->cat_ID;
$cat_id_gum = get_ancestors($cat_id_gum,\'category\');
array_shift($cat_id_gum);
$cat_id_gum = $cat_id_gum[0];
// $cat_id_gum is now your parent category

$script = \'<script type="text/javascript">ggv2id=\\\'%s\\\';</script> <script type="text/javascript" src="http://g2.gumgum.com/javascripts/ggv2.js"></script>\';

// the key is the category
// the value is the gum code
$gum_codes = array(
  \'1\' => \'75803baa\',
  \'34\' => \'b737914c\'
);

printf($script,$gum_codes[$cat_id_gum]);

结束
