问题 I'm starting a new project in Yii2 and Composer (after a few projects with YII 1). I created a new "advanced project" with composer. Everything is okay but, I'm wondering what is the best way to customize the bootstrap theme? I think copying the whole bootstrap less to the backend and to the frontend and edit the two variables file and compile it isn't the right way. So: is it somehow possible to extend the less files downloaded by the composer and edit only the two variables file? 回答1:

问题 In Yii2, using Html::activeDropDownList , I can submit data in a form like the following: <?= Html::activeDropDownList($model, 'category', ArrayHelper::map($categories, 'id', 'name'), [ 'multiple' => 'multiple', 'class' => 'multiselect', ]) ?> Is there a way to specify pre-selected categories in the above?

问题 I am trying to work what the point of the environments folder is. Originally I had the idea that you could point the webserver to the different dev and prod folders in the environment folder but after reading up a bit I realise this is not the case. In Yii 1 you would solve this by just having multiple index.php 's i.e.: index.php index-local.php So the question is what benefit does this new environment structure actually give me over the old way? 回答1: I've found environments very useful in

问题 I've read through Yii2 documentation several times. I also googled and I couldn't find anything useful yet. The problem is I do not understand the concept of the environment folders. Please let me explain: I can use branches in Git (for dev, staging and production) *-local.conf files are ignored by Git and they won't be pushed to staging or production in anyway Why I have to duplicate all my controllers, views and other files in environment/dev & environment/prod ? In what folders I actually

问题 I had a project in Yii1.x and now I am using Yii2 for the same projects Project hierarchy is something like this Project1(yii1)/all yii files + project2(yii2) project2(yii2)/frontend + /common + /backend Now I want to know if is it possible to use project2/common/models in project1/protected/controllers How can I achieve this task?

问题 I'm trying to execute some code inside a Yii2 controller as I need some code from the model to be accessible within the behaviors section so I can pass the model as a parameter and avoid running duplicate queries; however I also need to be able to find out what action is being called, but I am not having much luck. I have tried using beforeAction but it seems this gets run AFTER the behaviours code runs, so that doesn't help me. I then tried using init , but it seems the action isn't

问题 I have an ajax function that triggers an entry deletion from my database. I need to do CSRF validation for the same. How can I do that? I am sending the CSRF cookie along with my post request, but Yii 2.0 is not validating it and any input that is passed through ajax is reaching the server. How do I do CSRF validation for ajax requests. Whether we need to manually set cookie and check? 回答1: You don't need to manually set cookie. If you are using jQuery CSRF token will be sent automatically.
