编写新增控制器
public function add(){
$brand=D('brand');
if(IS_POST){
if($brand->create()){
if($brand->add()){
$this->success('添加品牌成功！',U('index'));
}else{
$this->error('添加品牌失败！');
}
}else{
$this->error($brand->getError());
}
return;
}
$this->display();
}编写品牌的model文件
<?php
namespace Admin\Model;
use Think\Model;
class BrandModel extends Model {
protected $_validate = array(
array('brand_name','require','品牌名称不得为空！',1),
);
public function _before_insert(&$data,$option){
if($_FILES['brand_logo']['tmp_name']){
$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->autoSub = false;
$upload->savePath = './Public/Uploads/Brand/'; // 设置附件上传目录
$upload->rootPath = './';
$info = $upload->uploadOne($_FILES['brand_logo']);
$logo=$info['savepath'].$info['savename'];
$image = new \Think\Image();
$image->open($logo);
$image->thumb(100, 30)->save($logo);
$data['brand_logo']=$logo;
}
}
}这里要着重讲解.
_before_insert是thinkphp框架中的前置操作，他的意思是当我们在执行当前操作的时候会检测有没有前置操作，如果存在则优先执行。
这里执行前置操作添加品牌的时候先上传图片
if($_FILES['brand_logo']['tmp_name']){
$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->autoSub = false;
$upload->savePath = './Public/Uploads/Brand/'; // 设置附件上传目录
$upload->rootPath = './';
$info = $upload->uploadOne($_FILES['brand_logo']);$info = $upload->uploadOne($_FILES['brand_logo']);
获得图片的路径和名称
$image = new \Think\Image(); $image->open($logo); $image->thumb(100, 30)->save($logo); $data['brand_logo']=$logo;
