几年前，我创建了一个插件（未公开），在我使用的WooCommerce版本（5.8.1）中运行良好。然而，在某个时候，管理员设置页面停止工作。我现在才注意到它（WC 7.6.0），因为我几乎从来没有使用过那个页面，所以我不知道什么时候改变了。
我的错误是：

Een fout van het type E_ERROR werd veroorzaakt op regelnummer 664 van het bestand <my-document-root>/wp-content/plugins/woocommerce/src/Internal/ProductAttributesLookup/LookupDataStore.php. Foutmelding: Uncaught TypeError: Automattic\WooCommerce\Internal\ProductAttributesLookup\LookupDataStore::add_product_attributes_lookup_table_settings(): Argument #1 ($settings) must be of type array, null given in <my-document-root>/wp-content/plugins/woocommerce/src/Internal/ProductAttributesLookup/LookupDataStore.php:664

我创建了一个很小的无用的插件来复制这个。我想在第83行（return woocommerce_admin_fields($this->getSettings());）出错了。带有管理设置的表单显示正确，但提交按钮没有显示，我确实得到了上面的关键错误。
下面的代码只是在WooCommerce设置->产品-> Foo Bar中添加了一个设置页面

<?php
/**
 * @package Foo_Bar
 * Plugin Name: Foo Bar
 * Description: With this plugin, nothing useful can be done
 * Version: 0.0.0
 * Author URI: http://oveas.com/
 * WC tested up to: 7.6.0
 */
 
if (!defined('ABSPATH')) {
    die;
}

function FooBar_getSettingsId()
{
    return 'foo-bar';
}

function FooBar_Activate()
{
    global $wpdb;

    $settingsId = FooBar_getSettingsId();

    $query = $wpdb->prepare("SELECT * FROM $wpdb->options WHERE `option_name`=%s", $settingsId);

    $db_result = $wpdb->get_row($query);
    if(is_null($db_result) || $db_result == "" || !isset($db_result)) {
        $query = $wpdb->prepare(
              "INSERT INTO $wpdb->options SET "
            . '  option_name = %s'
            . ', option_value = %s'
            . ', autoload = %s'
            , $settingsId
            , 'a:2:{s:10:"option-one";s:7:"default";s:10:"check-this";s:3:"yes";}'
            , 'yes'
        );
        $wpdb->query($query);
    }
}

function FooBar_Deactivate()
{
}

function FooBar_Uninstall()
{
    global $wpdb;

    $settingsId = FooBar_getSettingsId();

    $query = $wpdb->prepare("DELETE FROM $wpdb->options WHERE `option_name` = '$settingsId'", '');
    $db_result = $wpdb->query($query);
}

class FooBar
{
    public function __construct()
    {
        if (is_admin()) {
            $this->createAdminSettings();
        }

    }

    public function createAdminSettings()
    {
        add_filter('woocommerce_get_sections_products', array($this, 'addSection'), 10, 1);
        add_filter('woocommerce_get_settings_products', array($this, 'adminSettings'), 10, 2);
    }

    public function addSection($sections)
    {
        $sections['foo-bar'] = 'Foo Bar';
        return $sections;
    }

    public function adminSettings($settings, $currentSection)
    {
        if ($currentSection == 'foo-bar' && function_exists('woocommerce_admin_fields')) {
             // This is where it goes wrong: settings are added, but then there's some fatal
            return woocommerce_admin_fields($this->getSettings());
        } else {
            return $settings;
        }
    }

    public function getSettings()
    {
        $settings['section_title'] = array(
              'name'     => 'Foo Bar'
            , 'type'     => 'title'
            , 'desc'     => 'Some useful description'
            , 'id'       => FooBar_getSettingsId() . '[section-title]'
        );

        $settings['option-one'] = array(
              'name' => 'Option one'
            , 'type' => 'select'
            , 'options' => array(
                  'default'        => 'Use WooCommerce default'
                , 'something-else' => 'Something else'
                , 'both'           => 'Both'
            )
            , 'desc' => 'Make a useful selection'
            , 'id'   => FooBar_getSettingsId() . '[option-one]'
        );

        $settings['check-this'] = array(
              'name' => 'Make a selection'
            , 'type' => 'checkbox'
            , 'desc' => 'Enable or disable this'
            , 'id'   => FooBar_getSettingsId() . '[check-this]'
        );

        return apply_filters('foo-bar-settings', $settings);
    }
}

function FooBar_Execute()
{
    if (in_array( 'woocommerce/woocommerce.php', apply_filters('active_plugins', get_option('active_plugins')))) {
        $plugin = new FooBar();
    }
}

register_activation_hook( __FILE__, 'FooBar_Activate' );
register_deactivation_hook( __FILE__, 'FooBar_Deactivate' );
register_uninstall_hook( __FILE__, 'FooBar_Uninstall' );

FooBar_Execute();

我找不到add_product_attributes_lookup_table_settings()在哪里以及如何调用，所以欢迎所有建议。插件的其余部分（如产品特定设置-不在此代码示例中）工作正常，只是这个页面。

如果其他人遇到同样的问题：我现在发现问题了。
我改变了什么：

  • 第70行上对$this->getSettings()的调用现在将$settings作为参数传递
  • 在getSettings()的末尾，即返回apply_filters()的结果，我直接返回$settings（原来是118行，现在是122行）。

我还添加了一个section end（第117-120行），但这只是因为保存按钮（以前没有显示）显示在表单上方。
以下是完整的工作代码：

<?php
/**
 * @package Foo_Bar
 * Plugin Name: Foo Bar
 * Description: With this plugin, nothing useful can be done
 * Version: 0.0.0
 * Author URI: http://oveas.com/
 * WC tested up to: 7.7.2
 */
 
if (!defined('ABSPATH')) {
    die;
}

function FooBar_getSettingsId()
{
    return 'foo-bar';
}

function FooBar_Activate()
{
    global $wpdb;

    $settingsId = FooBar_getSettingsId();

    $query = $wpdb->prepare("SELECT * FROM $wpdb->options WHERE `option_name`=%s", $settingsId);

    $db_result = $wpdb->get_row($query);
    if(is_null($db_result) || $db_result == "" || !isset($db_result)) {
        $query = $wpdb->prepare(
              "INSERT INTO $wpdb->options SET "
            . '  option_name = %s'
            . ', option_value = %s'
            . ', autoload = %s'
            , $settingsId
            , 'a:2:{s:10:"option-one";s:7:"default";s:10:"check-this";s:3:"yes";}'
            , 'yes'
        );
        $wpdb->query($query);
    }
}

function FooBar_Deactivate()
{
}

function FooBar_Uninstall()
{
    global $wpdb;

    $settingsId = FooBar_getSettingsId();

    $query = $wpdb->prepare("DELETE FROM $wpdb->options WHERE `option_name` = '$settingsId'", '');
    $db_result = $wpdb->query($query);
}

class FooBar
{
    public function __construct()
    {
        if (is_admin()) {
            $this->createAdminSettings();
        }

    }

    public function createAdminSettings()
    {
        add_filter('woocommerce_get_sections_products', array($this, 'addSection'), 10, 1);
        add_filter('woocommerce_get_settings_products', array($this, 'adminSettings'), 100, 2);
    }

    public function addSection($sections)
    {
        $sections['foo-bar'] = 'Foo Bar';
        return $sections;
    }

    public function adminSettings($settings, $currentSection)
    {
        if ($currentSection == 'foo-bar' && function_exists('woocommerce_admin_fields')) {
            return $this->getSettings($settings);
        } else {
            return $settings;
        }
    }

    public function getSettings($settings)
    {
        $settings['section_title'] = array(
              'name'     => 'Foo Bar'
            , 'type'     => 'title'
            , 'desc'     => 'Some useful description'
            , 'id'       => FooBar_getSettingsId() . '[section-title]'
        );

        $settings['option-one'] = array(
              'name' => 'Option one'
            , 'type' => 'select'
            , 'options' => array(
                  'default'    => 'Use WooCommerce default'
                , 'something-else' => 'Something else'
                , 'both'       => 'Both'
            )
            , 'desc' => 'Make a useful selection'
            , 'id'   => FooBar_getSettingsId() . '[option-one]'
        );

        $settings['check-this'] = array(
              'name' => 'Make a selection'
            , 'type' => 'checkbox'
            , 'desc' => 'Enable or disable this'
            , 'id'   => FooBar_getSettingsId() . '[check-this]'
        );

        $settings[] = array(
              'type' => 'sectionend'
            , 'id'   => FooBar_getSettingsId() . '[section-title]'
        );

        return $settings;
    }
}

function FooBar_Execute()
{
    if (in_array( 'woocommerce/woocommerce.php', apply_filters('active_plugins', get_option('active_plugins')))) {
        $plugin = new FooBar();
    }
}

register_activation_hook( __FILE__, 'FooBar_Activate' );
register_deactivation_hook( __FILE__, 'FooBar_Deactivate' );
register_uninstall_hook( __FILE__, 'FooBar_Uninstall' );

FooBar_Execute();

我没有弄清楚为什么和什么时候改变了这一点，但其他人可能会受益于解决方案。
