WordPress different categories call different templates

This refers to the default article type template (single.php,category.php)

Application Scenarios:

Default article default has 2 categories (news, game information)

all sub-categories under news call " News list template , news content Template "

all sub-categories under game profile call " game Data list template , game profile content Template "

Article List page category.php

Judge in category.php.

If the subcategory belongs to the news root category, the News list template is called

If the subcategory belongs to the game data root category, the game Profile list template is called

The key here is "to determine if the sub-classification is a function of the root classification "

WordPress does not have a default function and requires the following code:

 //function Cate_is_in_descendant_category ($cats)
parameter $cats A category ID, multiple categories with ID array

If( !function_exists("Post_is_is_descendant_category" ) ) {    function cate_is_in_descendant_category($cats) {        foreach( (Array)$cats  as $cat ) {            //Get_term_children () accepts integer ID only            $descendants= Get_term_children ((int)$cat, "category" ); if($descendants&&is_category($descendants ) )                return true; }            return false; }}

is_category ( $category )
Parameters: $category

Mixed (optional) Category ID, category header title, category short tag Slug or ID array, title array, slugs array.
Default: None

Implementing operations

First, copy the two category.php files named "category1.php" and "category2.php" respectively.
Then, delete all the contents of the original category.php file and replace it with the following code:

<? PHP if  ) {    include(TemplatePath). '/category1.  Else  {    include(TemplatePath. '/category2. php ');}
?>

This means: Check the category page ID, if the ID belongs to category ID9, display category1.php, if not, display category2.php.

Article List page category.php

The key here is "to determine whether an article under sub-classification is a function of the root classification "

if( !function_exists("Post_is_in_descendant_category" ) ) {    function post_is_in_descendant_category($cats,$_post=NULL ) {        foreach( (Array)$cats  as $cat ) {            //Get_term_children () accepts integer ID only            $descendants= Get_term_children ((int)$cat, "category" ); if($descendants&&in_category($descendants,$_post ) )                return true; }            return false; }}

Implementing operations

<? phpif (Cate_is_in_descendant_category (2) ) {    include (TemplatePath. '/single1. php ');} Else {    include (TemplatePath. '/single2. php ');}
?>
