編寫新增控制器
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();
}寫品牌的model檔案<?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;
}
}
}這裡要重講解._before_insert是thinkphp框架中的前置操作，他的意思是當我們在執行目前操作的時候會偵測有沒有前置操作，如果存在則優先執行。 rrreee
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']);取得圖片的路徑與名稱$info = $upload->uploadOne($_FILES['brand_logo']);產生縮圖
