php------验证码

改代码只是简单实现了验证码，需要后续进行修改完善

PHP代码：TP_3.2.2/Home/Control/LoginController.class.php

?php
/**
 * Created by PhpStorm.
 * User: root
 * Date: 2018/4/16
 * Time: 13:13
 */

namespace Home\Controller;


use Think\Controller;

function check_verify($code, $id = ""){
    $verify = new \Think\Verify();
    return $verify->check($code, $id);
}

class loginController extends Controller
{
    /**
     *
     * 验证码生成
     */
    public function verify_c(){
        $Verify = new \Think\Verify();
        $Verify->fontSize = 18;
        $Verify->length   = 4;
        $Verify->useNoise = false;
        $Verify->codeSet = '1';
        $Verify->imageW = 130;
        $Verify->imageH = 50;
        //$Verify->expire = 600;
        $Verify->entry();
    }

    function login(){
        $this->display('log/login');
    }
    function jumppage(){
        echo "jum.......";
        $this->display('index/index');
    }
    /**
     *
     */
    function getinfo()
    {
     //   echo I('get.age'); // 相当于 $_GET['id']

        if(0==strcasecmp("1",I('post.fname')))
        {
            echo "姓名验证通过";
        }else
        {
            echo "姓名验证没有通过";
        }
        if(0==strcasecmp("1",I('post.age')))
        {
            echo "ps验证通过";
        }else
        {
            echo "ps验证没有通过";
        }
        $verify = I('post.verify','');
        if(!check_verify($verify)){
            $this->error("亲，验证码输错了哦！",$this->site_url,9);
        }else{

            echo I('post.verify');
        }

          //  header('jump','login/jumppage');
         $this->success("正在登录",U('base/login'));//此处是跳转到另一个页面
    }

}
