注册学⽣信息⾸先我们要检测学⽣信息不能为空，然后检测前台传过来的学号是否已经注册，若已注册，返回学号存在；反之添加进数据库student表： public function index($no,$name,$sex,$age){
//⾮空
if(empty($no)||empty($name)){
return $this->ajaxReturn(array('error'=>true,'msg'=>'学号或姓名不能为空'));
}
$data['no'] = $no;
$data['name'] = $name;
$data['sex'] = $sex;
$data['age'] = $age;
$stu = M('student');
//不可重复
if($stu->where("no = '{$no}'")->find()){
return $this->ajaxReturn(array('error'=>true,'msg'=>'学号已存在'));
}else{
$id=$stu->add($data);
}
if($id){
$this->ajaxReturn(array('error'=>false,'id'=>$id));
}else{
$this->ajaxReturn(array('error'=>true,'msg'=>'添加失败'));
}
}

页⾯效果：
根据后台的代码我们可以知道我们需要传4个参数：no,name,sex,age post⽅式提交；
给form表单绑定⼀个bindsubmit，当我们点击注册时，会把值存在e⾥边
submit: function (e) {
// console.log(e);
}
我们使⽤wx.resquest，将所需的参数传给后台
这样就连接起来了
js代码：
data: {
sex: '男',
},
backbefore:function(){
wx.navigateBack({
delta:1
})
},
switchChange: function (e) {
// console.log(e);
if (e.detail.value) {
this.setData({ sex: '男' })
} else {
this.setData({ sex: '⼥' })
}
},
submit: function (e) {
// console.log(e);
url:'xxxxxxxxxxxxx',//这⾥调⽤⾃⼰的接⼝
method: 'POST',
data: {
no: e.,

success: (res) => {
// console.log(res.data);
if () {
wx.showToast({
title: res.data.msg,
icon: 'none',
duration: 2000,
})
} else {
wx.setStorage({

data: res.data.id
});
wx.showToast({

icon: 'success',
duration: 2000

}
}
})
},
