WordPress page location and ID classification location function

 

Below are common page judgment statements

Is_home () === home page
Is_single () === article page
Is_page () === Page
Is_category () === document category page
Is_tag () === Article tab
Is_archive () === archive page
Is_404 () ==== page 404
Is_search () === search result page
Is_feed () === Subscription Page

 

How can we use these statements? For example:

If I want to set the word "Skyball homepage" to only display on the homepage, this is the case. <? Php if (is_home () {?> Skyball homepage <? Php }?>

In the preceding example, the yellow and bold parts can be replaced at will. You can determine how to display is_single () [only on the document Page] or is_archive () [Archive page], etc.

Since it can be set to display only a certain content on a page, can it be set to prohibit the display of the same content only on a certain page? The answer is yes.

Syntax note: | represents or, & represents and ,! The preceding syntax allows you to define the page display content more flexibly. The Syntax example is as follows:

! Is_home () ==== all pages except the home page are displayed
! Is_category (4) ==== is only displayed in a category where ID is not 4
Is_home () | is_category ('movies') ==== displays the categories named movies on the home page.
Is_page ('about') ==== displayed only on the page named 'about'
Is_home ()&&! Is_paged () ==== displayed on the homepage, not displayed on the page
