Changing the value here doesn t make sense  because it s active field  It means value will be synchronized with the model value   Just change the value of  model- gt hidden1 to change it  Or it will be changed after receiving data from user after submitting form   With using non-active hidden input it will be like that   use yii helpers Html        echo Html  hiddenInput  name    value     But the latter is more suitable for using outside of model

You can use this code line in view form     lt     form- gt field  model   hidden1  - gt hiddenInput   value   gt  your value   - gt label false    gt    Please refere this as example  If your need to pass currant date and time as hidden input   Model attribute is  created on  and its value is retrieve from date  Y-m-d H i s     just like  2020-03-10 09 00 00       lt     form- gt field  model   created on  - gt hiddenInput   value   gt date  Y-m-d H i s    - gt label false    gt

Hello World   You see  the main question while using hidden input is what kind of data you want to pass  I will assume that you are trying to pass the user ID  Which is not a really good idea to pass it here because field   method will generate input and the value will be shown to user as we can t hide html from the users browser  This if you really care about security of your website  please check this link  and you will see that it s impossible to hide value attribute from users to see  so what to do then   See  this is the core of OOP in PHP  and I quote from Matt Zandstr in his great book PHP Objects  Patterns  and Practice fifth edition  I am still stuck with a great deal of unwanted flexibility  though  I rely on the client coder to change a ShopProduct object   s properties from their default values  This is problematic in two ways  First  it takes five lines to properly initialize a ShopProduct object  and no coder will thank you for that  Second  I have no way of ensuring that any of the properties are set when a ShopProduct object is initialized  What I need is a method that is called automatically when an object is instantiated from a class    Please check this example of using   construct   method which is mentioned in his book too        class ShopProduct           public  title            public  producerMainName           public  producerFirstName           public  price   0              public function   construct  title  firstName  mainName  price                 this- gt title    title               this- gt producerFirstName    firstName                 this- gt producerMainName    mainName                this- gt price    price                   And you can simply do this magic     product1   new ShopProduct  quot My Antonia quot   quot Willa quot   quot Cather quot  5 99    print  quot author    product1- gt getProducer    n quot    This produces the following   author  Willa Cather   In your case it will be something semilar to this  every time you create an object just pass the user ID to the user id property  and save yourself a lot of coding    Class Car     private  user id       your properties    public function   construct  title  firstName  mainName  price         this- gt user id    Yii   app- gt user- gt id          Your magic           Good luck  And Happy Coding

you can also do this   model- gt hidden1    your value     better put it on controller  form- gt field  model   hidden1  - gt hiddenInput  - gt label false     this is a better option if you set value on controller   model   new SomeModelName     if   model- gt load Yii   app- gt request- gt post     amp  amp   model- gt save          return  this- gt redirect   view    id    gt   model- gt group id       else        model- gt hidden1    your value       return  this- gt render  create              model    gt   model
