我有一个页面模型.它在数据库表中有以下列:
I want to update only "形象" column value.
这是我的代码:
public function delImage($path, $身份证件) {
$page = Page::find($身份证件);
$page->where('形象', $path)->update(array('形象' => 'asdasd'));
\File::delete($path);
}
it throws me an error, that i am trying to use where() on a non-object. How can i correctly update my "形象" column value?
You may try this:
Page::where('id', $id)->update(array('image' => 'asdasd'));
There are other ways too but no need to use Page::find($id); in this case. But if you use find() then you may try it like this:
$page = Page::find($id);
// Make sure you've got the Page model
if($page) {
$page->image = 'imagepath';
$page->save();
}
你也可以使用:
$page = Page::findOrFail($id);
So, it'll throw an exception if the model with that id was not found.
