我使用woocommerce简单拍卖插件，为了满足我的需要，我对插件中的一个文件进行了一些自定义。我需要通过自己的修改，以某种方式重写原始函数或其部分。我该怎么做？
原始函数如下所示：
public function __construct(){
$this->plugin_prefix = \'wc_simple_auctions\';
$this->plugin_basefile = plugin_basename(__FILE__);
$this->plugin_url = plugin_dir_url($this->plugin_basefile);
$this->plugin_path = trailingslashit(dirname(__FILE__));
$this->auction_types = array(\'normal\' => __(\'Normal\', \'wc_simple_auctions\'), \'reverse\' => __(\'Reverse\', \'wc_simple_auctions\'));
$this->auction_item_condition = array(\'new\' => __(\'New\', \'wc_simple_auctions\'), \'used\' => __(\'Used\', \'wc_simple_auctions\'));
add_action(\'woocommerce_init\', array(&$this, \'init\'));
//require_once( ABSPATH .\'wp-includes/pluggable.php\');
}
我需要此更改覆盖它：
public function __construct(){
$this->plugin_prefix = \'wc_simple_auctions\';
$this->plugin_basefile = plugin_basename(__FILE__);
$this->plugin_url = plugin_dir_url($this->plugin_basefile);
$this->plugin_path = trailingslashit(dirname(__FILE__));
$this->auction_types = array(\'normal\' => __(\'Normal\', \'wc_simple_auctions\'), \'reverse\' => __(\'Reverse\', \'wc_simple_auctions\'));
$this->auction_item_condition = array(\'new\' => __(\'Brand New\', \'wc_simple_auctions\'), \'used\' => __(\'1/10\', \'wc_simple_auctions\'),
\'2/10\'=> __(\'2/10\', \'wc_simple_auctions\'), \'3/10\'=> __(\'3/10\', \'wc_simple_auctions\'), \'4/10\'=> __(\'4/10\', \'wc_simple_auctions\'), \'5/10\'=> __(\'2/10\', \'wc_simple_auctions\'), \'6/10\'=> __(\'6/10\', \'wc_simple_auctions\'), \'7/10\'=> __(\'7/10\', \'wc_simple_auctions\'), \'8/10\'=> __(\'8/10\', \'wc_simple_auctions\'), \'9/10\'=> __(\'9/10\', \'wc_simple_auctions\'), \'10/10\'=> __(\'10/10\', \'wc_simple_auctions\'));
add_action(\'woocommerce_init\', array(&$this, \'init\'));
//require_once( ABSPATH .\'wp-includes/pluggable.php\');
}
我该怎么做？
此处添加了调用上述内容的代码段：
public function product_write_panel(){
global $post;
$product = get_product( $post->ID );
// Pull the video tab data out of the database
$tab_data = maybe_unserialize(get_post_meta($post->ID, \'woo_auction_tab\', true));
if(empty($tab_data)){
$tab_data[] = array();
}
echo \'<div id="auction_tab" class="panel woocommerce_options_panel">\';
woocommerce_wp_select( array( \'id\' => \'_auction_item_condition\', \'label\' => __( \'Item condition\', \'wc_simple_auctions\' ), \'options\' => apply_filters( \'simple_auction_item_condition\',$this->auction_item_condition) ) );
}

原则上，除非插件有文档化的API和/或过滤器，否则如果您希望将来能够升级它，就不应该再使用核心挂钩了。
如果没有合适的东西可用，你应该联系作者并提出要求，或者决定你要承担全部责任，然后直接交出来。
在您的特定情况下，您可能能够在对象初始化后更改该属性，但下一版本可能不再存在该属性。
Edit: 因为有一个过滤器，你只需要像这样使用它
function wpse_242093_auctions($auctions) {
return array(\'new\' => __(\'Brand New\', \'wc_simple_auctions\'), \'used\' => __(\'1/10\', \'wc_simple_auctions\'),
\'2/10\'=> __(\'2/10\', \'wc_simple_auctions\'), \'3/10\'=> __(\'3/10\', \'wc_simple_auctions\'), \'4/10\'=> __(\'4/10\', \'wc_simple_auctions\'), \'5/10\'=> __(\'2/10\', \'wc_simple_auctions\'), \'6/10\'=> __(\'6/10\', \'wc_simple_auctions\'), \'7/10\'=> __(\'7/10\', \'wc_simple_auctions\'), \'8/10\'=> __(\'8/10\', \'wc_simple_auctions\'), \'9/10\'=> __(\'9/10\', \'wc_simple_auctions\'), \'10/10\'=> __(\'10/10\', \'wc_simple_auctions\'));
}
add_filter(\'simple_auction_item_condition\',\'wpse_242093_auctions\');
