我需要帮助PHP中的插件,类和方法。
我试图从我自己的一个函数调用插件文件中的方法,但我似乎并没有让它工作。
PS。正在使用的插件是Learndash-Group-Registration而不是Woocommerce。 Woocommerce用于它的产品和订单。
这是我尝试调用该方法的文件:(file.php)
$args = array(
'order_id' => 1234,
);
include '/wp-content/plugins/ld-
group-registration/modules/class-wdm-woocommerce.php';
WdmLdWooCommerce::wdmCourseOrderCompletedCreateGroup( $args[ 'order_id' ] );
类-WDM-woocommerce.php
<?php
namespace wisdmlabs\ldgroups;
defined('ABSPATH') || exit;
if (!class_exists('WdmLdWooCommerce')) {
class WdmLdWooCommerce
{
public function wdmCourseOrderCompletedCreateGroup($order_id)
{
if ($this->wdmIsRenewalOrder($order_id)) {
return;
}
$order = new \WC_Order($order_id);
$product_id = null;
$group_data = array();
$items = $order->get_items();
$group_creation_done = get_post_meta($order_id, 'wdm_successful_group_creation', true);
if ($group_creation_done == 'done') {
return;
}
if (WC_VERSION < '3.0.0') {
foreach ($items as $item) {
$product_id = $item[ 'product_id' ];
$quantity = apply_filters('wdm_modify_total_number_of_registrations', $item[ 'qty' ], $product_id);
$product_type = wdmGetProductType($product_id);
$group_registration = isset($item[ 'Group Registration' ]) ? $item[ 'Group Registration' ] : '';
//$courses = maybe_unserialize(get_post_meta($product_id, '_related_course', true));
$courses = '';
if ($product_type == 'variable-subscription') {
$variation_id = $item['variation_id'];
if (!empty($variation_id)) {
$courses = maybe_unserialize(get_post_meta($variation_id, '_related_course', true));
}
$product_id = $variation_id;
} else {
$courses = maybe_unserialize(get_post_meta($product_id, '_related_course', true));
}
if (!empty($courses) && $group_registration != '') {
$uid = $order->get_user_id();
$user1 = new \WP_User($uid);
$user1->add_role('group_leader');
$user1->remove_role('customer');
$user1->remove_role('subscriber');
$group_data[ 'leader' ] = $uid;
$group_data[ 'course' ] = $courses;
$this->wdmCreateLearndashGroup($group_data, $order, $order_id, $quantity, $product_id, $product_type);
update_post_meta($order_id, 'wdm_successful_group_creation', 'done');
}
}
} else {
foreach ($items as $key_item_id => $item) {
$key_item_id = $key_item_id;
$product_id = $item[ 'product_id' ];
//$quantity = $item[ 'qty' ];
$quantity = apply_filters('wdm_modify_total_number_of_registrations', $item[ 'qty' ], $product_id);
$product_type = wdmGetProductType($product_id);
$group_registration = isset($item[ 'Group Registration' ]) ? $item[ 'Group Registration' ] : '';
$courses = '';
if ($product_type == 'variable-subscription') {
$variation_id = $item['variation_id'];
if (!empty($variation_id)) {
$courses = maybe_unserialize(get_post_meta($variation_id, '_related_course', true));
$product_id = $variation_id;
}
} else {
$courses = maybe_unserialize(get_post_meta($product_id, '_related_course', true));
}
if (!empty($courses) && $group_registration != '') {
$uid = $order->get_user_id();
$user1 = new \WP_User($uid);
$user1->add_role('group_leader');
$user1->remove_role('customer');
$user1->remove_role('subscriber');
$group_data[ 'leader' ] = $uid;
$group_data[ 'course' ] = $courses;
$this->wdmCreateLearndashGroup($group_data, $order, $order_id, $quantity, $product_id, $product_type);
update_post_meta($order_id, 'wdm_successful_group_creation', 'done');
}
}
}
// exit;
}
}
?>
这不是完整的插件文件,但它包含我想要调用的方法和类。
当我尝试以这种方式调用方法时,我收到错误消息:
'致命错误:无法声明类wisdmlabs \ ldgroups \ WdmLdWooCommerce,因为该名称已在C:\ wamp64 \ www \ meritmind \ site \ public \ wp-content \ plugins \ ld-group-中使用在第6行注册\ modules \ class-wdm-woocommerce.php
当我删除'include'行时,我收到此错误消息:
'致命错误:未捕获错误:在第108行的C:\ wamp64 \ www \ meritmind \ site \ public \ wp-content \ themes \ meritgo \ file.php中找不到类'WdmLdWooCommerce'
我不明白我做错了什么。有一次,它说我没有声明类,但是当我使用include声明Class时,它已经声明了Class。
非常感谢som的帮助,
最好的问候,Ledung
答案 0 :(得分:0)
这失败有两个原因:
1)您使用的是include而不是include_once。通常使用_once
意味着如果代码之前已成功使用过(在这种情况下会使第二次定义的类停止),则代码不会重复。
2)您的class_exists('WdmLdWooCommerce')
无法正常工作,因为这不是完整的班级名称,即,这总是返回false,因为WdmLdWooCommerce&#39; WdmLdWooCommerce&#39;不存在,但\wisdmlabs\ldgroups\WdmLdWooCommerce
应该存在。
