将代码另存为一个php文件，后台开启插件 post_content; // Here we split it into lines $lyrics = explode( "\n", $lyrics ); // And then randomly choose a line return wptexturize( $lyrics[ mt_rand( 0, count( $lyrics ) - 1 ) ] );}
post_content;
// Here we split it into lines
$lyrics = explode( "\n", $lyrics );
// And then randomly choose a line
return wptexturize( $lyrics[ mt_rand( 0, count( $lyrics ) - 1 ) ] );
}
// This just echoes the chosen line, we'll position it later
function nihao() {
$chosen = nihao_get_lyric();
echo "$chosen [MORE]
";
}
// Now we set that function up to execute when the admin_notices action is called
add_action( 'head_notices', 'nihao' );
// We need some CSS to position the paragraph
function nihao_css() {
echo "
";
}
add_action( 'head_notices', 'nihao_css' );
?>
在header.php或index.php或footer.php等任何你想要的位置放入以下代码
插件说明
原插件是直接将要显示的内容放在插件文件内，不方便编辑， 所以采用直接调用一个文章或者页面的内容的方式显示，插件代码17行显示的就是ID为2的发布内容。 $lyrics = get_post( 2 )->post_content; 演示地址：http://gaobukai.com/nihao
