WeChat applet and PHP send template message notification

This article mainly introduces the WeChat applet and PHP for sending template message notifications. It has a certain reference value. Now I share it with you. Friends in need can refer to it.

First of all, the template message interface requires Written on the backend server. 【Add! Currently, WeChat applet template messages can only be triggered by and sent to me. 】

Modified in 2018.4.9: One form submission can issue one item, and the number of items submitted for multiple submissions is independent and does not affect each other;

One payment can issue 3 items. The number of items issued for multiple payments is independent and does not affect each other.

Mini program

According to the template information, the corresponding value is output to the background, as well as the formid Or prepay_id, the openid of the notifier.

.wxml file

I forgot to add it before, because it must be formid or prepay_id. So there has to be a button to trigger the acquisition. If you have any methods that don’t require manual triggering, please feel free to enlighten me! ! ! ! I have been thinking about this question for a long time! !

  <form bindsubmit="tiXian" report-submit=&#39;true&#39;>
    <button class=&#39;btn&#39; form-type="submit" disabled="{{lock}}">提现</button>
  </form>

.js file

  /**
   * 触发微信提醒
   */
  remindMessage: function (formid){
    var that = this
    wx.request({
      method: 'POST',
      url: 'https://www.**********************_message.php',//后台接口
      data: {
        o_id: that.data.allthing.openid,
