我想使用Carbon Fields WordPress插件。安装完成后，我根据网站上的说明改变了结构，只适应了OOP。

<?php
class Test
{
    public function __construct()
    {

    }
}

$wpTest = new Test();

它不起作用。我该如何解决？

Answer 1

我找到了问题的答案。从部分来看，问题是我在访问vendor/autoload.php后连接了__construct()。

下面解决此任务的一个例子

use Carbon_Fields\Container;
use Carbon_Fields\Field;



class PluginOption
{

    public function __construct()
    {
        require_once( 'vendor/autoload.php' );
        \Carbon_Fields\Carbon_Fields::boot();
        add_action( 'carbon_fields_register_fields', array( $this, 'crb_attach_theme_options') );
    }

    public function crb_attach_theme_options()
    {
        Container::make( 'theme_options', __( 'Plugin Option', 'crb' ) )
        ->add_fields( array(
            Field::make( 'text', 'crb_text', 'Text Field' ),
            ) );
    }

}

$wpTest = new PluginOption();

Answer 2

问题作者本身的answer可能适用于他自己的特定目的。

但是，如果你来这个问题很长，你可能想要在你自己的插件中集成Carbon Fields（由于这个问题的语言化）。在这种情况下，您应该知道（至少）一个问题，即碳场数据可用的点;如果你想在插件执行时检索碳场数据。

TL; DR：在carbon_fields_fields_registered动作挂钩是您可以获得碳场值的最早阶段。首先必须在carbon_fields_register_fields动作钩子中定义这些字段。有关其他说明，您还可以查看this answer。

所以这是一个确保有正确时间的引导程序：

use Carbon_Fields\Container;
use Carbon_Fields\Field;

class YourFancyPlugin
{

    public function __construct()
    {
        add_action( 'after_setup_theme', array( $this,
            'load_carbon_fields'
        ) );

        add_action( 'carbon_fields_register_fields', array( $this,
            'register_carbon_fields'
        ) );

        /* will succesfuly retrieve the data of the fields registered at
         * carbon_fields_register_fields action hook
         * if you retrieve the data before carbon_fields_fields_registered action hook
         * has fired it won't work
         */
        add_action( 'carbon_fields_fields_registered', array( $this,
            // picked this name only to emphasize whats going on
            'carbon_fields_values_are_available'
        ) );

        /* do all the stuff that doesn't rely on values of your Carbon Fields */
    }

    public function load_carbon_fields()
    {
        require_once 'vendor/autoload.php'; // modify depending on your actual setup
        \Carbon_Fields\Carbon_Fields::boot();
    }

    public function register_carbon_fields()
    {
        Container::make( 'theme_options', 'YourFancyPlugin options' )
            -> add_fields( array(
                Field::make( 'text', 'YourFancyPlugin_option_1')
            ) );
    }

    public function carbon_fields_values_are_available()
    {
        /* retrieve the values of your Carbon Fields related to your plugin */
        var_dump( carbon_get_theme_option( 'YourFancyPlugin_option_1' ) );
        /* do all the stuff that does rely on values of your Carbon Fields */
    }

}

new YourFancyPlugin();

在自定义插件类中使用Carbon Fields
