最近做了一个项目，其中有需求，要求我们实现此功能：商品成交时发送短信，下面小编贴出核心代码，方面大家以后学习。

html代码省略.....

Model代码省略.....

核心代码如下所示：

　　/*

* -------------------------------------------------

* 修改状态 public 

* Author: lzp Time:--

* -------------------------------------------------

*/

public function changeStateAction() {

$id = $_REQUEST['id'];

$result = $this->changeConfirmState($id);

if ($result) {

$this->success("修改成功");

} else {

$this->error("修改失败");

}

}

private function changeConfirmState($id) {

$reg = $this->priceModel->selectPrice(['id'=>['eq', $id]]);

$rel = $this->demandModel->selectDemand(['id'=>['eq',$reg[]['demand_id']]]);

$demand_id = $reg[]['demand_id'];

$reg['demand'] = $this->priceModel->selectPrice(['demand_id'=>['eq',$demand_id]]);

foreach ($reg['demand'] as $key => $value){

if($value['phone'] == $reg[]['phone']){

unset($reg['demand'][$key]);

}else{

$new[] = $value['phone'];

}

}

$new = [''=>'********'];

if((time()-strtotime($rel[]['create_time']))> ){

echo "<script>alert('已超时!');history.back();</script>";

die;

}else if(strtotime($rel[]['finish_time'])>){

echo "<script>alert('已成交!');history.back();</script>";

die;

}else{

$data_demand = [ 'is_available' => , 'finish_time' => date("Y-m-d H:i:s") ];

$result['Price'] = $this->priceModel->savePrice( ['id'=>['eq',$id]], ['state'=>] );

$result['Demadn'] = $this->demandModel->saveDemand(['id'=>['eq',$reg[]['demand_id']]] , $data_demand);

$mobile = implode(",", $new);

$content = "此条需求已成交，下次再来哟!";

smsApp($mobile,$content); //发短信

return $result;

}

}

以上代码是小编给大家贴的核心的代码，代码还算简单，所以没给大家写太多的注释
