以下是我的示例customizer的设置和控件：

$wp_customize->add_setting( \'themename_img\', array(
    \'type\'           => \'theme_mod\',
    \'default\'        => get_template_directory_uri() . \'/images/\' . rawurlencode( get_bloginfo( \'name\' ) ) . \'.gif\',
    \'capability\'     => \'edit_theme_options\',
    \'transport\'      => \'refresh\'
));
$wp_customize->add_control( new WP_Customize_Image_Control( $wp_customize, \'img\', array(
    \'label\'      => __( \'Image\', \'theme-slug\' ),
    \'section\'    => \'section_id\',
    \'settings\'   => \'themename_img\',
)));

图像位于http://localhost/wordpress/wp-content/themes/theme-name/images/\' . rawurlencode( get_bloginfo( \'name\' ) ) . \'.gif\' 已存在。。但是为什么控件和设置没有设置为默认值，需要单击；“默认”按钮，然后再将其设置为默认值？

但是当我改变\'themename_img\'s默认自\'default\' => get_template_directory_uri() . \'/images/\' . rawurlencode( get_bloginfo( \'name\' ) ) . \'.gif\' 到\'default\' => \'image.gif\' 即使路径位置无效，设置的默认值也将自动设置为默认值。如何将自定义程序的设置和控件最初设置为get_template_directory_uri() . \'/images/\' . rawurlencode( get_bloginfo( \'name\' ) ) . \'.gif\' 住址有其他选择吗？

更新：

调试后rawurlencode( get_bloginfo( \'name\' ) ) 代码是可疑的，这就是为什么我将其包含在我的示例中！

$encode = get_template_directory_uri().\'/images/\'.get_bloginfo(\'name\').\'.gif\';
...
    \'default\' => $encode,
...

$decode = base64_decode(get_theme_mod(\'themename_img\'));
