QUESTION
I'm new to Yii2 and returning to PHP dev after a very long time. I have an extensive background in Java development. I stumbled onto this recommendation in the docs for ActiveRecord:
__construct()public methodDefined in: yii\base\BaseObject::__construct()
Constructor.
The default implementation does two things:
- Initializes the object with the given configuration
$config.- Call init().
If this method is overridden in a child class, it is recommended that
- the last parameter of the constructor is a configuration array, like
$confighere.- call the parent implementation at the end of the constructor.
My question is about the last sentence:
call the parent implementation at the end of the constructor.
As a Java dev, this advice seems very weird to me. In Java, not only is it recommended to call the parent constructor as the very first call from your overridden constructor, this is even enforced and it's actually impossible to do it any other way. Either your parent constructor is called first implicitly, or, if you make an explicit call, it MUST be the very first statement in your method. This is enforced by the compiler.
Theoretically, this makes a lot of sense to me. Because as long as you did not call the parent constructor, your parent class did not have the chance to initialize, so any code you write in the constructor before calling the parent constructor would be working with a half-initialized object.
Looking at some SO answers I found, they seem to be going against the advice in the official docs and call the parent::__construct before their own custom logic, as I would expect it. For example, the accepted answer in the question How can I create a constructor in a Yii2 model shows an example where they call the parent first:
ANSWER
Answered 2022-Apr-02 at 06:21@michal-hynčica correctly stated the reason for your ambiguity(Worthy of votUp).
But since you mentioned that the official reference, on the same page (BaseObject), this issue is explicitly stated: line
- In order to ensure the above life cycles, if a child class of BaseObject needs to override the constructor,
- ....
- of the constructor, and the parent implementation should be called at the end of the constructor.
According to the description of this link (similar to your question):
init () is called which further calls bootstrap () to run bootstrapping components.
As a result, this is done to ensure configuration.
The same process is done in the controller class and the main module.
Of course, there are many examples like this on the php site (depending on the need)
Also read lifecycles and entry script in yii. components and structure-applications. Good luck
QUESTION
I have a Bootstrap 3 Modal that conditionally needs to move to the left so that data on the main page can still be seen when the dialog is open.
If a
class="modal-left", the modal should appear to the left of the window. Otherwise, it should be rendered as normal on the top center of the screen.
I am using the Yii2 Modal widget.
...ANSWER
Answered 2022-Mar-14 at 08:42In your code you start opening modal then you start loading its content right after. The modal showing doesn't wait for content loading. And, the content loading doesn't wait for modal either. So it's basically gamble what will be finished first.
You can use load() method's complete callback to start showing modal after its content has been load:
QUESTION
I am using onmotion/yii2-widget-apexcharts. In my chart I have series with ~ 20 data sets but I don't want show them all after page loads (like it's toggled off), instead it would be nice if chart could show only selected series names with option toggle those who are hidden. Primary need is to toggle all series off when page loads, perfect need is toggle off selected series. Can anyone help me with this?
...ANSWER
Answered 2022-Feb-28 at 17:05You can disable specific series_name by adding JS code to the widget initialization. id is generated, so it can help to specify it explicitly.
QUESTION
I need to override the renderPageButton() method in the Yii2 LinkPager widget. The method documentation specifically says "You may override this method to customize the generation of page buttons" but I can't figure out how to do that. Thanks.
...ANSWER
Answered 2022-Feb-24 at 12:49The class you want to override is documented here.
You can override it in the following way:
- Create a new directory in your yii2 app root folder, like widgets
- Create a new php file (like MyLinkPager.php) and a new class in it (MyLinkPager) which extens yii\widgets\LinkPager
- You can use "app\widgets" namespace (i.e. if you are working with the basic yii2 app)
- In your class, implement only the function you want to override from the original class
- Use your new class wherever you want instead of the original one
QUESTION
I have a question. I have a migration file, that batchInserts an admin user and a normal user into a database. Now I have the files ready and they work fine. However, the password used to have a md5 hash during insert in Yii1.1 something like this:
'password'=>md5('admin')
My question is, can I do something similar in Yii2 with bcrypt? Where I encrypt the password during creation? I use batchInsert('users', ['column1', 'column2' ...], ['Jon', 'Doe' ...], ['Jane', 'Doe'...])
Any help is greatly appreciated!
...ANSWER
Answered 2022-Feb-02 at 09:35The proper way to hash password in Yii2 is using yii\base\Security::generatePasswordHash().
This method uses password_hash() function with PASSWORD_DEFAULT constant as algorithm. I think currently that constant still refers to bcrypt algorithm. But it's meant to be future-proof. When PHP moves to another algorithm you wouldn't need to change your code. If the password_hash() function is not available the generatePasswordHash() methods fallback to crypt() function.
In migration you can use application components in same way you would use them anywhere else. For example:

I have created a sitemap.xml for my yii2 project. I put it in root folder but I can't seem to access it with this URL: https://www.mywebsite.com/sitemap.xml. I need the URL to input it to Google Search Console.
I've searched everywhere but it seems that information about yii2 and sitemap are very rare.
What is the correct way to place the sitemap.xml? I believe it can be fixed in htaccess file but I don't know how.

It's so simple.
The suites are picked up from *.suite.yml files.
So,in addition to unit.suite.yml and functional.suite.yml inside tests folder you should add an integrational.suite.yml file with settings. In this case tests from integrational folder will be work as well.
QUESTION
My issue has to do with the automated creation of the migration history table when first executing yii migrate/up --interactive=0.
I was able to override the database access credentials for the migrations themselves. (see example below)
For my web application, I have a user default that has the following GRANTs: SELECT, INSERT
For migrations, I want to use my admin user who has additional GRANTs for DDL.
When executing the migration Yii2 wants to create a migration table with the default user which leads to a permission denied error.
How can I set the database user for the migration table creation?
My migration script:
...ANSWER
Answered 2021-Oct-16 at 15:13Migrations are run from console.
That means, the console.php config file is loaded instead of your main.php config. So one way, that would also affect any other console commands you might have, would be to change the db configuration in the components section of the console config.
