详解WordPress开发中get_header()获取头部函数的用法,wordpressheader

函数意义详解
从当前主题调用header.php文件。是不是很简单?好吧,如果你是新手的话这里要提醒一下,这里的get和get_children()、get_category中的get略有不同之处。

get_header函数声明(定义)
之前写文章很少会写到函数定义的代码,后来自己翻看的时候发现这个习惯不太好,所以决定,只要篇幅允许,就会把函数主题贴出来,方便自己翻看。
get_header 函数,声明(定义)的位置,是在 wp=include/general-template.php 文件的第 24 – 36 行左右的位置。

function get_header( $name = null ) {
 do_action( 'get_header', $name );
 
 $templates = array();
 if ( isset($name) )
 $templates[] = "header-{$name}.php";
 
 $templates[] = 'header.php';
 
 // Backward compat code will be removed in a future release
 if ('' == locate_template($templates, true))
 load_template( ABSPATH . WPINC . '/theme-compat/header.php');
}
Copy after login

get_header函数的使用

<&#63;php get_header( $name ); &#63;>
Copy after login

很简单,从上面的函数声明中我们也能看出,该函数只接受一个变量作为参数。

参数解释
$name ,从上面的函数声明中我们可以看出,$name是一个字符串型变量,用来调用header的别名模板,
比如 $name = “ab”;
也就是我们这样

<&#63;php 
  $name = “ab”
  get_header( $name ); 
 
&#63;>
Copy after login

这将会调用 header-ab.php 文件作为头部文件的调用。

例子:

1.简单的 404 页面

下面的代码是一个简单模板文件,专门用来显示 "HTTP 404: Not Found" 错误的 (这个文件应该包含在你的主题中,名为 404.php)

<&#63;php get_header(); &#63;>
<h2 id="Error-Not-Found">Error 404 - Not Found</h2>
<&#63;php get_sidebar(); &#63;>
<&#63;php get_footer(); &#63;>

Copy after login

2.多种头部

为不同的页面显示不同的头部

<&#63;php
if ( is_home() ) :
 get_header( 'home' );
elseif ( is_404() ) :
 get_header( '404' );
else :
 get_header();
endif;
&#63;>
Copy after login

这些为 home 和 404 准备的头部应该分别命名为  header-home.php 和 header-404.php 。
