You can just create a getTotal method in your model, which returns price * quantity.

In your model. You’ll use PHP there :)

If you don’t know what a model is, you should really read the guide before proceeding.

Also, I made The complete beginner’s study guide for the Yii Framework, which can help you.

Hi,

First, you may want to rename your "getprice" method to "getTotal".

If you just want to have the total filled in automatically to be displayed to the user, you don’t need the new method or even to have an input field.

Just create a span to hold the total:




<div class="row">

  <span id="total">Total: $ <span id="value"></span></span>

</div>

And use Javascript to fill it (assuming you have the classes “price” and “quantity” on your inputs). I’m using jQuery below:




$('.price, .quantity').change(function() {

  $('.value').val($('.price').val() * $('.quantity').val());

});

This code is not tested, but should get you started.

I Have Tested and it works but total appear NaN not value from price * quantity

What Should I do ??

Either one is NaN. Add a check with isNaN before you try to do the math.

its Ok now, Thanks very much for you help bro
