一、验证码
验证码参数
例题：登录时验证下验证码
LoginController.class.php
<?php
namespace Home\Controller;
use Think\Controller;
class LoginController extends Controller
{
public function Login()
{
if(empty($_POST))
{
$this->display();
}
else
{
//判断验证码是否正确
$code = $_POST["yzm"];//用户输入的验证码的值
$verify = new \Think\Verify(); //生成验证码
if($verify->check($code))
{
if($_POST["uid"]!="")
{
$model = D("users");
$uid = $_POST["uid"];
$pwd = $_POST["pwd"];
$attr = $model->field("Pwd")->find($uid);
//echo $attr["pwd"];
if($pwd == $attr["pwd"])
{
session("uid",$uid);
$this->success("登录成功","Main");
}
else
{
$this->error("登录失败");
}
}
else
{
$this->error("登录失败");
}
}
else
{
$this->error("验证码错误");
}
}
}
//生成验证码的操作
public function yzm()
{
$config = array(
‘fontSize‘ => 30, // 验证码字体大小
‘length‘ => 5, // 验证码位数
//‘useNoise‘ => false, // 关闭验证码杂点
‘imageW‘ => 200,//宽度
‘imageH‘ => 100,//高度
//‘useZh‘ => true,//中文验证码
//‘fontttf‘ => ‘Arvo-Regular.ttf‘,//指定验证码字体
);
$Verify = new \Think\Verify($config);
//$Verify->fontttf = ‘7.ttf‘; // 验证码字体使用 ThinkPHP/Library/Think/Verify/ttfs/5.ttf
$Verify->entry();

每个文件信息又是一个记录了下面信息的数组，包括：
//文件上传
public function ShangChuan()

{
$upload = new \Think\Upload();// 实例化上传类
$upload->maxSize = 3145728 ;// 设置附件上传大小
$upload->exts = array(‘jpg‘, ‘gif‘, ‘png‘, ‘jpeg‘);// 设置附件上传类型
//$upload->mimes = ‘‘;
$upload->rootPath = ‘./Public/‘;
$upload->savePath = ‘Uploads/‘; // 设置附件上传目录
$upload->saveName = ‘‘;//保持上传文件名不变
// 上传文件
$info = $upload->upload();
var_dump($info);
if(!$info)
{
$this->error($upload->getError());
}
else
{
// 上传成功 获取上传文件信息
foreach($info as $file)
{
$url=$file[‘savepath‘].$file[‘savename‘];
