form表单中必须有的一个属性:
enctype=”multipart/form-data”
html的写法:
<form action="__SELF__" method="post" enctype="multipart/form-data">
<table width="100%"class="cont">
<tr>
<td>照片:</td>
<td width="20%"><input type="file" name="pic" id="pic" /></td>
<td colspan="3"><input class="btn" type="submit" value="提交" /></td>
<td> </td>
</tr>
</table>
</form>
php后台写法:
<?php
namespace Admin\Controller;
use Org\Util\Date;
use Think\Controller;
use Think\Image;
use Think\Upload;
class UserController extends Controller {
public function add(){
$user = M('user');
if(!empty($_POST)){
$user = $user->create();
//判断传入的图片有没有问题
if($_FILES['pic']['error'] == 0){
$config = array(
'rootPath' => './Application/public/image/' // 设置图片保存路径
);
//new一个上传模型
$upload = new Upload($config);
//上传图片
$pic = $upload->uploadOne($_FILES['pic']);
//将图片保存到数据库中
$user['big_pic'] = $pic['savepath'].$pic['savename'];
//生成缩略图
$img = new Image();
//大图片的路径
$big_img = $upload->rootPath.$user['big_pic'];
//打开大图片
$img->open($big_img);
//设置图片大小
$img->thumb(200,300);
//设置绝对路径
$small_img = $upload->rootPath.$pic['savepath'].'small_'.$pic['savename'];
//保存
$img->save($small_img);
//将图片名称存入数据库
$user['img'] = $pic['savepath'].'small_'.$pic['savename'];
}
$user['create_date'] = date("Y-m-d H:i:s");
$msg = "添加失败";
if(M("user")->add($user))
$msg = "添加成功";
$this->redirect(show_list,null,3,$msg);
}
$this->display();
}
