How to create Rating with Stars in Visual Force page ?

To create the Stars Ratings in VF page you need : 
  • Basic knowledge of creating custom VF page and Apex class
  • Fill Star Image 
  • Empty Star Image 

First let's create a Apex Class and declare an Integer variable to store selected rating value in VF page as shown below : 

RatingCtrl

1
2
3
public class RatingCtrl {
    public Integer rating { get; set; }
}


After creating the apex class create a visualforce page with Radio Button and CSS for stars as shown below

      Hello, you have to save the fillstar and emptystar images in your static resource. After that you can get them using {!$Resource.fillstar}.

      Let me know if you have any questions.

      Hi, you can create a custom formula field for that to calculate the rating on the parent object.

    Hi Kapil,

    Thanks for the code, appreciate your help.

    In testing we are facing an issue on iPhone(version 13.1 onwards) & iPad, in which after selecting a star ratings when user clicks anywhere on the screen, selection of stars disappears or gets unselected. The issue comes due to "styleClass="star-rating" in outputPanel, which has all the css.
    Can you help in this regards. Thanks in advance!

      Hi FAIZ, as far I remember I created those based on the 13" 1920i resolution. I would suggest you to have another css for mobile with different width and size for the ratings.
      .star-rating-mobile{
      // Your code here
      }
