6.2.4 提问：如何在WordPress主题中集成⾃定义后台选项？
集成⾃定义后台选项到WordPress主题要在WordPress主题中集成⾃定义后台选项，需要使⽤WordPress提供的Theme Customization API。下⾯是实现的步骤：
1. 创建⼀个后台选项页⾯：使⽤add_theme_page()函数创建⼀个新的后台选项页⾯。function custom_theme_options_page() {
2. 渲染后台选项页⾯：创建⼀个渲染后台选项页⾯的函数，可以在这个函数中添加表单元素供⽤户进⾏设置。function render_custom_theme_options_page() {// Add form elements here }
3. 保存⽤户设置：使⽤update_option()函数保存⽤户在后台选项页⾯中设置的值。function save_custom_theme_options() {// Save options using update_option() }
4. 在主题中应⽤设置：在主题中读取保存的选项值，并将其应⽤到对应的地⽅，例如修改主题的颜⾊或布局。⽰例：
