How to manually customize the number of articles displayed in WordPress
Jun 18, 2020 pm 01:28 PM
The following column WordPress Tips will introduce you to the detailed method of manually customizing the number of articles displayed in WordPress. I hope it will be helpful to friends in need!
WordPressThe number of articles displayed per page is specified in the background reading settings and will be applied to the blog list page (usually Home page), search page, tag page, category page and time index page. The structure of adding these pages is different. For example, some display the title and abstract, and some only display the title, so specifying the same number of pages does not apply to each page. page. To specify the number of articles displayed on each page according to the page type, you need to write code to implement it.
Recommended method
Modify the number of articles displayed on each page, that is, modify the posts_per_page parameter, and put the following code into functions.php to achieve this. The code comes from WordPress Answers.
function custom_posts_per_page($query){
if(is_home()){
$query->set('posts_per_page',8);//首頁每頁顯示8篇文章
}
if(is_search()){
$query->set('posts_per_page',-1);//搜索頁顯示所有匹配的文章，不分頁
}
if(is_archive()){
$query->set('posts_per_page',25);//archive每頁顯示25篇文章
}//endif
}//function
//this adds the function above to the 'pre_get_posts' action
add_action('pre_get_posts','custom_posts_per_page');With WordPress’ conditional tags, you can extend this code arbitrarily.
Method not recommended
It is not recommended to modify the theme template directly, for example, use query_posts before the index.php main loop to change the number of articles displayed on each page
query_posts( 'posts_per_page=5' );
Disadvantages:
First, increase the number of queries
Second, the flexibility is not high. If categories and tags have their own templates, you need to repeat the query_posts trick in those templates.
Third, you need to be particularly careful when using query_posts. If you forget to restore the global variable, inexplicable errors may occur.
