小白我最近刚学thinkphp3.2.3,，准备做毕业设计，现在卡在一个问题上。
该模块可以添加数据就是修改和删除不了，不知道怎么解决。望大神解救。
不知道是不是传入的参数有问题
数据表
CREATE TABLE IF NOT EXISTS `item` ( `inumber` smallint(3) unsigned zerofill NOT NULL AUTO_INCREMENT COMMENT '项目编号', `iname` varchar(64) CHARACTER SET latin1 NOT NULL COMMENT '项目名称', `quantity` smallint(2) DEFAULT '1' COMMENT '参赛人数（>1表示团体项目）', `proportion` smallint(6) NOT NULL COMMENT '参赛规模', PRIMARY KEY (`inumber`), UNIQUE KEY `itemNumber` (`inumber`)) ENGINE=MyISAM DEFAULT CHARSET=utf8 COMMENT='项目' AUTO_INCREMENT=6 ;
控制器
public function update($inumber) { //默认显示添加表单 if (!IS_POST) { $model = M('item')->where('inumber='.$inumber)->find(); $this->assign('item',$model); $this->display(); } if (IS_POST) { $model = D("item"); if (!$model->create()) { $this->error($model->getError()); }else{ if ($model->save()) { $this->success("更新成功", U('Item/index')); } else { $this->error("更新失败"); } } } } <!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title></title></head><body><form method="post" action="{:U('Item/update?inumber=')}{$item.inumber}"> <div class="form-group"> <label>项目名</label> <input type="text" name="iname" class="form-control" value="{$item.iname}" placeholder="输入项目名"> <label >参赛人数</label> <select name="quantity"> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> <option value="6">6</option> <option value="7">7</option> <option value="8">8</option> <option value="9">9</option> <option value="10">10</option> <option value="11">11</option> </select> <label>参赛单位数</label> <input type="text" name="proportion" class="form-group" value="{$item.proportion}" placeholder="输入参赛单位数"> <input type="hidden" name="inumber" value="{$item.inumber}"> <button type="submit">提交</button> </div></form></body></html>
回复讨论(解决方案)
控制器 14行 你少了where条件
if($model->where('inumber='.I('inumber'))->save() !==false){ $this->success(‘修改成功’);}else{ $this->error('修改失败！')}
if($model->where('inumber='.I('inumber'))->save() !==false){ $this->success(‘修改成功’);}else{ $this->error('修改失败！')} 我改了还是不行，改成I('post.inumber')也不行
忘了贴入口了
<foreach name="model" item="v"> <tr> <td>{$v.inumber}</td> <td>{$v.iname}</td> <td>{$v.quantity}</td> <td>{$v.proportion}</td> <td><a href="{:U('item/update?inumber=')}{$v.inumber}">编辑</a> | <a href="{:U('item/delete?inumber=')}{$v.inumber}" style="color:red;" onclick="javascript:return del('您真的确定要删除吗？\n\n删除后将不能恢复!');">删除</a></td> </tr> </foreach> 解决了！！！是入口路由出错了
<td><a href="{:U('item/update?inumber=')}{$v.inumber}">编辑</a> | <a href="{:U('item/delete?inumber=')}{$v.inumber}" style="color:red;" onclick="javascript:return del('您真的确定要删除吗？\n\n删除后将不能恢复!');">删除</a></td>
