在我的php脚本文件中使用woocomerce函数

我看到许多使用Woocomece库的例子，但没有一个包括任何库

这是一个例子：

$post = array(
    'post_author' => $user_id,
    'post_content' => '',
    'post_status' => "publish",
    'post_title' => $product->part_num,
    'post_parent' => '',
    'post_type' => "product",
);

//Create post
$post_id = wp_insert_post( $post, $wp_error );
if($post_id){
    $attach_id = get_post_meta($product->parent_id, "_thumbnail_id", true);
    add_post_meta($post_id, '_thumbnail_id', $attach_id);
}

wp_set_object_terms( $post_id, 'Races', 'product_cat' );
wp_set_object_terms( $post_id, 'simple', 'product_type');

update_post_meta( $post_id, '_visibility', 'visible' );
update_post_meta( $post_id, '_stock_status', 'instock');
update_post_meta( $post_id, 'total_sales', '0');
update_post_meta( $post_id, '_downloadable', 'yes');
update_post_meta( $post_id, '_virtual', 'yes');
update_post_meta( $post_id, '_regular_price', "1" );
update_post_meta( $post_id, '_sale_price', "1" );
update_post_meta( $post_id, '_purchase_note', "" );
update_post_meta( $post_id, '_featured', "no" );
update_post_meta( $post_id, '_weight', "" );
update_post_meta( $post_id, '_length', "" );
update_post_meta( $post_id, '_width', "" );
update_post_meta( $post_id, '_height', "" );
update_post_meta( $post_id, '_sku', "");
update_post_meta( $post_id, '_product_attributes', array());
update_post_meta( $post_id, '_sale_price_dates_from', "" );
update_post_meta( $post_id, '_sale_price_dates_to', "" );
update_post_meta( $post_id, '_price', "1" );
update_post_meta( $post_id, '_sold_individually', "" );
update_post_meta( $post_id, '_manage_stock', "no" );
update_post_meta( $post_id, '_backorders', "no" );
update_post_meta( $post_id, '_stock', "" );

// file paths will be stored in an array keyed off md5(file path)
$downdloadArray =array('name'=>"Test", 'file' => $uploadDIR['baseurl']."/video/".$video);

$file_path =md5($uploadDIR['baseurl']."/video/".$video);


$_file_paths[  $file_path  ] = $downdloadArray;
// grant permission to any newly added files on any existing orders for this product
// do_action( 'woocommerce_process_product_file_download_paths', $post_id, 0, $downdloadArray );
update_post_meta( $post_id, '_downloadable_files', $_file_paths);
update_post_meta( $post_id, '_download_limit', '');
update_post_meta( $post_id, '_download_expiry', '');
update_post_meta( $post_id, '_download_type', '');
update_post_meta( $post_id, '_product_image_gallery', '');

他们将此代码放在何处，因此没有：

致命错误：未捕获错误：调用未定义函数

唯一的方法是在脚本中包含库吗？

我认为您正在尝试为woo commerce制作一个插件。如果是，那么这里有一个制作简单的woo commerce插件的示例

您需要首先检查woo commerce插件是否已激活。要在主插件文件中实现这一点，请编写以下代码

if (in_array('woocommerce/woocommerce.php', apply_filters('active_plugins', get_option('active_plugins')))) {

  // code for woocommerce goes here        

}

下面是您应该在插件文件中使用的完整演示代码

<?php

/**
 * Plugin Name: Demo URL button for Woocommerce
 */


/**
 * Check if WooCommerce is active
 **/

if (in_array('woocommerce/woocommerce.php', apply_filters('active_plugins', get_option('active_plugins')))) {

    include 'functions.php';

}
