WordPress添加自定义字体：【纯代码+插件】两种方式

方法1，纯代码的方式添加，适合不喜欢用插件的同学：

//1，允许在WordPress后台media媒体库上传字体，将下面代码添加到主题的functions.php
class FJJ_SUPPORT_TTF_MEDIA{
    public function __construct(){
        add_filter('upload_mimes', array($this,'fjj_upload_media_mimes'));
        add_filter( 'wp_check_filetype_and_ext', array($this,'fjj_check_types'), 10, 4 );
    }
    function fjj_upload_media_mimes($fjj_mimes) {
        $fjj_mimes['ttf'] = 'application/x-font-ttf';
        $fjj_mimes['otf'] = 'application/x-font-otf';
        $fjj_mimes['eot'] = 'application/x-font-eot';
        $fjj_mimes['woff'] = 'application/x-font-woff';
        $fjj_mimes['woff2'] = 'application/x-font-woff2';
        return $fjj_mimes;
    }
    function fjj_check_types( $checked, $file, $filename, $mimes ) {
        if ( ! $checked['type'] ) { 
            $check_filetype     = wp_check_filetype( $filename, $mimes );
            $ext                = $check_filetype['ext'];
            $type               = $check_filetype['type'];
            $proper_filename    = $filename; 
            $checked = compact( 'ext','type','proper_filename' );
        } 
        return $checked; 
    }
}
new FJJ_SUPPORT_TTF_MEDIA();

//2，将下载好的字体，后缀是ttf格式，上传到WordPress后台media媒体库，上传成功后，获取到字体的文件路径，
//类似：http://127.0.0.1/wp-content/uploads/2023/09/Super-Dream.ttf

//3，将下面代码添加到主题的style.css：
@font-face {
    font-family: 'SuperDream'; /* 字体名称 */
    src: url('http://127.0.0.1/wp-content/uploads/2023/09/Super-Dream.ttf') format('truetype'); /* 字体文件的路径和格式 */
    font-weight: normal; /* 字体的重量 */
    font-style: normal; /* 字体的样式 */
}

//4，在WordPress前端调用新字体：
h1.product_title.entry-title {
    font-family: SuperDream;
}
