但是找了很久也没有发现问题所在。麻烦大神帮忙看一下。万谢

一下是php错误页面提示内容

?php
require_once 'add-ons/acf-google-font-selector-field/acf-google_font_selector.php';
// 1. customize ACF path
add_filter('acf/settings/path', 'my_acf_settings_path');
function my_acf_settings_path( $path ) {

$path = get_template_directory() . '/inc/acf/';
return $path;
}

// 2. customize ACF dir
add_filter('acf/settings/dir', 'my_acf_settings_dir');
function my_acf_settings_dir( $dir ) {
$dir = get_template_directory_uri() . '/inc/acf/';
return $dir;
}
// 3. Hide ACF field group menu item
add_filter('acf/settings/show_admin', '__return_'.(defined('BLT_DEBUG') ? 'true' : 'false'));
// 4. Include ACF
include_once( get_template_directory() . '/inc/acf/acf.php' );
// Create options pages
if( function_exists('acf_add_options_page') ) {

acf_add_options_page(array(
'page_title' => 'Theme Settings',
'menu_title' => BLT_THEME_NAME. ' Settings',
'menu_slug' => 'theme-general-settings',
'capability' => 'edit_theme_options',
'redirect' => false
));

acf_add_options_sub_page(array(
'page_title' => 'Purchase Key',
'capability' => 'edit_theme_options',
'menu_title' => 'Purchase Key',
'parent_slug' => 'theme-general-settings',
));
}
add_filter('acf/settings/load_json', function($paths) {

$paths = array(get_template_directory() . '/acf-json');
if(is_child_theme())
{
$paths[] = get_stylesheet_directory() . '/acf-json';
}
return $paths;
});

Answer 1

acf_add_options_sub_page(array(
'page_title' => 'Purchase Key',
'capability' => 'edit_theme_options',
'menu_title' => 'Purchase Key',
'parent_slug' => 'theme-general-settings', //这里多了个逗号吧
));

追问

修改后，依旧是同样的错误提示。下面
add_filter('acf/settings/load_json', function($paths) {

没有错误么？

追答

acf-init.php的48行是啥

追问

是add_filter('acf/settings/load_json', function($paths) {

这一行

追答

add_filter函数的第二个参数 $function_to_add：（回调）（必需）应用过滤器时被调用函数的名称。从说明上来看，好像不可以用匿名函数,只能是函数名称
