ThinkPHP模型类中不能调用save方法
这些天由于工作的需要,在WBlog3.12版本的基础上做个会员模块。
在测试更新会员头像时,发现了ThinkPHP的一个问题:在模块的模型类,无法执行更新查询语句!
下面是更新数据的代码片断,上传头像成功,$uploadList[0]['savename']为更新头像时成功获取的图片的保存名,调试时已经确保 $data['thumb'] 的值不为空。代码如下:
class AttachModel extends Model{ ... $data['thumb'] = $uploadList[0]['savename'];//获取的更新头像的保存名称 $list = M('Member')->where(array('id'=>1))->save($data); }
上面的代码似乎没有错误,我也这样认为,可是也因为这种貌似没有错误的代码,让我花了好多时间在其它代码中寻找错误,到头来问题偏偏出现在上面的代码片段中--把它放到控制器中问题就解决了。呵呵,好痛的测试结果啊!
经测试,在模型类中添加数据是没问题的,即上面的代码可以这样执行
class AttachModel extends Model{ ... $data['thumb'] = $uploadList[0]['savename'];//获取的更新头像的保存名称 $list = M('Member')->where(array('id'=>1))->add($data); //这里把save($data)改成add($data) ... }
我查阅了一下ThinkPHP核心包的模型类,类中包函着add和save两个方法,至于在模块的模型类中无法执行save,我仍在困惑着,但至少不会再把save写在模型类中。
