Question

我无法将自定义元数据添加到<head></head>自定义页面模板。

我google了很多，发现将其添加到我的自定义页面模板

get_header();
some code here ......

load mysql data and put that data in function mySEO()

function mySEO() {
echo '
<title>titleeee</title>
<meta name="description" content="Page description. No longer than 155 characters." />
<meta itemprop="name" content="The Name or Title Here">
<meta itemprop="description" content="This is the page description">
<meta itemprop="image" content="http://www.example.com/image.jpg">
<meta name="twitter:site" content="@publisher_handle">
<meta name="twitter:title" content="Page Title">
<meta name="twitter:description" content="Page description less than 200 characters">
<meta name="twitter:creator" content="@author_handle">
<meta name="twitter:image" content="http://www.example.com/image.html">

<meta property="og:title" content="Title Here" />
<meta property="og:type" content="article" />
<meta property="og:url" content="http://www.example.com/" />
<meta property="og:image" content="http://example.com/image.jpg" />
<meta property="og:description" content="Description Here" />
<meta property="og:site_name" content="Site Name, i.e. Moz" />';
}
add_action('wp_head','mySEO');
///some code here...
get_footer();

但没有任何反应我不会把任何东西放在页面的头部......什么是问题？

Answer 1

在调用HEADER之前，您应该在PAGE顶部包含所需数据的值。

这样，这些值可用于填充HEADER中包含的变量。

＆＃34; VEL＆＃34;回答我的问题：

你放了add_action（＆＃39; wp_head＆＃39;，＆＃39; mySEO＆＃39;）;和functions.php中的mySEO函数？ - vel

并在模板中调用mySEO函数

完整答案：

this is in function.php: 
function mySEO($title,$description,$image,$url) { echo '
<title>'.$title.'</title>
<meta name="description" content="'.$description.'" />
<meta itemprop="name" content="'.$title.'">
<meta itemprop="description" content="'.$description.'">
<meta itemprop="image" content="'.$image.'">
<meta name="twitter:site" content="@Tw">
<meta name="twitter:title" content="'.$title.'">
<meta name="twitter:description" content="'.$description.'">
<meta name="twitter:creator" content="@Tw">
<meta name="twitter:image" content="'.$url.'">
<meta property="og:title" content="'.$title.'" />
<meta property="og:type" content="article" />
<meta property="og:url" content="'.$url.'" />
<meta property="og:image" content="'.$image.'" />
<meta property="og:description" content="'.$description.'" />
<meta property="og:site_name" content="SITE" />'; 
}
add_action("wp_head","mySEO");

在mypage.php（自定义页面模板）中只调用函数mySEO（$ title，$ description，$ image，$ url）;

在自定义页面模板wordpress中添加自定义元数据
