<h1 style="color: black; text-align: left; margin-bottom: 10px;">直奔主题</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">新版的wordpress<span style="color: black;">增多</span>了自定义主题设置的功能,并且官方<span style="color: black;">亦</span><span style="color: black;">举荐</span><span style="color: black;">研发</span>者把<span style="color: black;">关联</span>的设置放到主题自定义里。默认的<span style="color: black;">状况</span>下,主题会自动开启<span style="color: black;">有些</span>自定义参数(即使<span style="color: black;">咱们</span>的主题还<span style="color: black;">无</span><span style="color: black;">运用</span>它们):</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/pgc-image/7ebdb1acf907450fa7b364e265e3f15f~noop.image?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1728363870&x-signature=GCmjY8p5c8leTPzu8MP4T8eCTIw%3D" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">咱们</span>在主题文件夹下<span style="color: black;">创立</span>一个<strong style="color: blue;">functions.php</strong>文件,这个文件会影响到主题的方方面面,<span style="color: black;">首要</span><span style="color: black;">咱们</span><span style="color: black;">创立</span>自定义的主题参数连接:</p>// Customizer
function my_customize_register($wp_customize) {
};
add_action( customize_register, my_customize_register );<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">关联</span>的主题设定<span style="color: black;">咱们</span>都会写到my_customize_register里,<span style="color: black;">咱们</span>先来<span style="color: black;">认识</span>三个基本概念:</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1. Section</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2. Settings</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3. Control</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">为了方便理解,<span style="color: black;">咱们</span><span style="color: black;">能够</span>把section当成设置的一级菜单,control是菜单里的设置控件,settings则是存储设置的容器。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">经过</span>查阅wordpress文档,<span style="color: black;">咱们</span>找出了<span style="color: black;">哪些</span>默认开启的section的<span style="color: black;">独一</span>id,<span style="color: black;">而后</span><span style="color: black;">咱们</span>在代码里把它们去除:</p>// Customizer
function my_customize_register($wp_customize) {
// remove default section
$wp_customize->remove_section(title_tagline);
$wp_customize->remove_section(custom_css);
$wp_customize->remove_section(static_front_page);
};<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">而后</span><span style="color: black;">咱们</span>添加自己的section、control、settings,<span style="color: black;">这儿</span><span style="color: black;">咱们</span>先盘点一下<span style="color: black;">日前</span>的<span style="color: black;">需要</span>,<span style="color: black;">咱们</span>需要对页面的公共顶部进行设置,公共顶部含有以下元素:</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1. 博客标题</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2. 主标语(slogan/tagline)</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3. 副标语</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">那样</span><span style="color: black;">咱们</span>在functions.php里实现代码是像<span style="color: black;">这般</span>的:</p>$wp_customize->add_section( header_setting , array(
title => __( Header Setting),
priority => 10,
) );
$wp_customize->add_setting( blog_title , array(
default => get_bloginfo(name),

$wp_customize->add_setting( main_tagline , array(

default => Across the Great Wall we can reach every corner in the world,
transport => refresh,
) );

input_blog_title,
array(
label => __( Blog Title),
section => header_setting,
settings => blog_title,
type => text,

input_main_tagline,
array(
label => __( Main tagline),
section => header_setting,
settings => main_tagline,

);
$wp_customize->add_control(

section => header_setting,
settings => sub_tagline,
type => textarea,
)
);<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">这儿</span><span style="color: black;">咱们</span>用到了三个<span style="color: black;">办法</span>:</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1. add_section</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2. add_settings</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3. add_control</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">对应section、settings、control的添加,需要<span style="color: black;">重视</span>的是,<span style="color: black;">咱们</span>在设置文本的title输出那里用到了魔术<span style="color: black;">办法</span><strong style="color: blue;">__()</strong>,这是为后期主题的国际化做准备,魔术<span style="color: black;">办法</span>__()和魔术<span style="color: black;">办法</span>_e()都是为了主题多语言而存在的,它们之间的<span style="color: black;">区别</span><span style="color: black;">便是</span>__()返回字符串,而_e()直接把文本在页面里输出,当然,它们都是<span style="color: black;">按照</span>当前系统设定的语言找到对应的语言包输出的,主题国际化的<span style="color: black;">关联</span>内容<span style="color: black;">咱们</span>在本系列的后期进行展开。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">这般</span>设定之后,<span style="color: black;">咱们</span>就<span style="color: black;">能够</span>在主题的任意位置调用这些设置好的内容,<span style="color: black;">此刻</span><span style="color: black;">咱们</span>把它们在home.php里<span style="color: black;">表示</span>出来<span style="color: black;">瞧瞧</span>。</p><body>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">还记得<span style="color: black;">咱们</span>在第1天<span style="color: black;">创立</span>框架时有添加的style amp-custom吗,<span style="color: black;">咱们</span>在里面添加一段css,让<span style="color: black;">咱们</span>的header凸显出来:</p><style amp-custom>
header {
width: 100vw;
height: 18.5185vw;
bac<span style="color: black;">公斤</span>round: gray;
}
</style><p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">刷新页面,<span style="color: black;">咱们</span>应该能看到<span style="color: black;">这般</span>的页面输出:</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">咱们</span>在主题自定义那里设定这些settings并点击发布时,页面里对应的部分就会发生变化了。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">接下来<span style="color: black;">咱们</span>顺便把主题的favicon参数<span style="color: black;">亦</span>实现了吧,favicon是<span style="color: black;">表示</span>在浏览器标签页上的小图标,<span style="color: black;">咱们</span><span style="color: black;">根据</span>之前的<span style="color: black;">办法</span>,<span style="color: black;">创立</span>一套settings和control,并绑定到<span style="color: black;">咱们</span>的section里:</p>$wp_customize->add_setting( favicon , array(

description => __( Favicon is what you see in <strong>browser tabs</strong>, bookmark bars),
section => header_setting,

width => 32,
height => 32,
)
) );<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">这儿</span><span style="color: black;">咱们</span>直接<span style="color: black;">运用</span>了wordpress的内置控件</p>WP_Customize_Site_Icon_Control,这个控件<span style="color: black;">能够</span>直接对<span style="color: black;">照片</span>进行上传和裁剪。
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">而后</span><span style="color: black;">咱们</span>在header.php公共头里<span style="color: black;">运用</span><span style="color: black;">运用</span>这个favicon:</p><?php

echo <link rel="shortcut icon" href=".$icon.">;
}
?><p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">这儿</span>需要<span style="color: black;">重视</span>的是<span style="color: black;">咱们</span>直接get_theme_mod取到的内容是一个数字id,<span style="color: black;">咱们</span>需要<span style="color: black;">运用</span>wp_get_attachment_url获取<span style="color: black;">照片</span>id对应的url路径。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">这般</span><span style="color: black;">咱们</span>刷新页面 ,就能在标签页上看到<span style="color: black;">咱们</span>设置好的的favicon了。</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/pgc-image/fb820f98f41c4cd88f2521b261e0ef87~noop.image?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1728363870&x-signature=pl7HzzlD0US8zlh2tf39aGAS1N8%3D" style="width: 50%; margin-bottom: 20px;"></div>
