WP Weixin

WP Weixin provides integration between WordPress and WeChat. Register or authenticate users automatically in WeChat browser, use WeChat to create an account or authenticate on computers by scanning a QR code with WeChat, share posts in WeChat Moments and conversations or extend the plugin for more features! Important notes

• Requires a China Mainland WeChat Official Account (Subscription or Service - Service is required if used with companion plugins dealing with payments).
• A domain used by WordPress must be registered in an Official Account's backend.
• The plugin itself does not require programming knowledge, and provides really useful functionalities out of the box. Where it really shines though is when used by developers to extend its functionalities (mainly through the pre-initialised JS SDK, the WeChat Responder, and various provided functions, actions and filters).
• Make sure to read the "TROUBLESHOOT, FEATURE REQUESTS AND 3RD PARTY INTEGRATION" section below and the full documentation before contacting the author.

Overview This plugin adds the following major features to WordPress:

• WP Weixin settings page: configure the plugin with an Official Account (or as many as you want in multisite) in English or Chinese out of the box, with instructions for each option.
• WeChat Authentication: automatically create and authenticate users in WordPress in the WeChat browser, or allow users to scan a QR code with WeChat when using classic browsers (social login).
• WeChat Account Binding: let users bind/unbind their existing WordPress account with their WeChat account. Integrated with WooCommerce and Ultimate Member account pages, and may be integrated with any membership/account/profile plugin easily.
• WeChat Share: Share posts and pages on Moments or Send to chat, in a pretty way. Triggers JavaScript events for developers on success and failure.
• Force WeChat mobile: to prevent users from browsing the website outside of the WeChat browser. If accessed with a classic browser, the page displays a QR code.
• Force following the Official Account: to harvest WeChat followers, forcing users to follow the Official Account before accessing the content.
• WordPress Users screen override: to display WeChat names and WeChat avatars if they exist, instead of the default values in the user screen.
• WP Weixin QR code generator: to create custom codes.
• Menu integration: allows to set the Official Account menus in WordPress when the WeChat Responder is enabled.
• Welcome message: sends a welcome message in WeChat when a user follows the Official Account ; allows to do so with WordPress when the WeChat Responder is enabled.
• Developers - WeChat Responder: for developers to receive and respond to calls made by WeChat's API.
• Developers - WeChat JS_SDK: the wx JavaScript global variable is pre-configured with a signed package to leverage the JavaScript SDK of WeChat in WordPress themes more easily.

Compatible with WooCommerce, WooCommerce Multilingual, WPML, Ultimate Member, WordPress Multisite, and many caching plugins. Companion Plugins

• Woo WeChatPay: a payment gateway for WooCommerce.
• WP Weixin Pay: an extension to enable money transfers to an Official Account.
• WP Weixin Broadcast: broadcast WordPress posts to WeChat followers, directly from WordPress

Developers are encouraged to build plugins and themes integrated with WeChat with WP Weixin as a core, leveraging its publicly available functions, actions and filters, or directly make use of the provided SDK. If you wish to see your plugin added to this list, please contact the author. Advanced - Multisite WP Weixin supports multisite installs of WordPress, wether using domain/subdomains or subdirectories. It can even support multiple Official Accounts, provided the proper filters are implemented. For more information, see a more extensive description of the multisite settings, and the Multisite section of the documentation. Unlike some plugins (commercial, obfuscated, and with dubious security standards), WP Weixin does not and will not rely on a crossdomain script dumped at the root of WordPress, but prefers to leverage the standard WordPress functions, actions and filters. Troubleshoot, feature requests and 3rd party integration Unlike most WeChat integration plugins, WP Weixin and its companion plugins published by the same author are provided for free. WP Weixin is regularly updated, and bug reports are welcome, preferably on Github. Each bug report will be addressed in a timely manner, but issues reported on WordPress may take significantly longer to receive a response. WP Weixin and all the companion plugins have been tested with the latest version of WordPress - in case of issue, please ensure you are able to reproduce it with a default installation of WordPress, Storefront theme if WooCommerce is active, and any of the aforementioned supported plugins if used before reporting a bug. Feature requests (such as "it would be nice to have XYZ") or 3rd party integration requests (such as "it is not working with XYZ plugin" or "it is not working with my theme") for WP Weixin and all its companion plugins will be considered only after receiving a red envelope (红包) of a minimum RMB 500 on WeChat (guarantee of best effort, no guarantee of result). To add the author on WeChat, click here, scan the WeChat QR code, and add "WP Weixin" as a comment in your contact request.
