我正在尝试使用基于this guide的WordPress ACF + ACE编辑器进行语法高亮显示。
我做到了这一点：
<?php
class acf_field_ace_code_editor extends acf_field
{
// vars
var $settings, // will hold info such as dir / path
$defaults; // will hold default field options
/*
* __construct

* Set name / label needed for actions / filters
*
* @since 3.6
* @date 23/01/13
*/
function __construct()
{
// vars
$this->name = 'ace_code_editor';
$this->label = __('Ace Code Editor');
$this->category = __("Basic",'acf'); // Basic, Content, Choice, etc
$this->defaults = array(
// add default here to merge into your field.
// This makes life easy when creating the field options as you don't need to use any if( isset('') ) logic. eg:
'ace_code_editor_type' => 'ace_html',
'ace_code_editor_theme' => 'theme_chrome'
);
// do not delete!
parent::__construct();
// settings
$this->settings = array(
'path' => apply_filters('acf/helpers/get_path', __FILE__),
'dir' => apply_filters('acf/helpers/get_dir', __FILE__),
'version' => '1.0.0'
);
}

如何添加正确的ACE JS脚本以在WP-admin区域内加载以及如何在前端正确呈现？
答案 0 :(得分：0)
似乎（只是一个猜测，我不熟悉这些）您使用acf-input-ace_code_editor两次相同的处理程序js和css来注册js和以下行中的css个文件（正在覆盖js处理程序）
wp_register_script( 'acf-input-ace_code_editor', $this->settings['dir'] . 'js/input.js', array('acf-input'), $this->settings['version'] );
wp_register_style( 'acf-input-ace_code_editor', $this->settings['dir'] . 'css/input.css', array('acf-input'), $this->settings['version'] );
然后你使用了
wp_enqueue_script(array(
'acf-input-ace_code_editor',
));
// styles
wp_enqueue_style(array(
'acf-input-ace_code_editor',
));
在这种情况下，您应该在注册文件时使用js和css的不同处理程序，例如
wp_register_script( 'acf-input-ace_code_editor_js', $this->settings['dir'] . 'js/input.js', array('acf-input'), $this->settings['version'] );
wp_register_style( 'acf-input-ace_code_editor_css', $this->settings['dir'] . 'css/input.css', array('acf-input'), $this->settings['version'] );
然后使用
wp_enqueue_script(array(
'acf-input-ace_code_editor_js',
));
// styles
wp_enqueue_style(array(
'acf-input-ace_code_editor_css',
));
希望如果在注册时给定路径正确，这将使脚本正确排队，并确保在给定路径上有正确的js文件。
