]
]);
but when i make this, the selection of each star not display correctly, half of star is selected.

Answer 1

I thought you only want to display the client side (with manual numbers). And you will not get numbers from DB
the correct way is to overwrite the star-rating file. Which should be referred to the Kartik forum.
You must overwrite that the first star has a zero score (highlight first star = 0)
However, you can use the following code in your model.
public function beforeSave($insert)
{
// if ($insert) { // only for Save (No Update)
if (!empty($this->Your_field)) {
$this->setAttribute('Your_field', $this->Your_field-3.75);
}
// }
return parent::beforeSave($insert);
}
Instead of your_field, enter your field name (field of the rate).

Answer 2

You have made the settings incorrectly.
Refer the plugin documentation and demos for details.
quotation krajee:
The logic for highlighting stars depends on the stars, min, max, and
step configurations. The percentage of each star to be highlighted for
each step, will be evaluated using the following expression:
STAR_HIGHLIGHT_PERCENT = (max - min) * step * 100 / stars
For example:
If min = 0, max = 5, step = 0.5, and stars = 5, then
STAR_HIGHLIGHT_PERCENT will evaluate to 50% of each star for each
step.
If min = 1, max = 5, step = 0.5, and stars = 5, then
STAR_HIGHLIGHT_PERCENT will evaluate to 40% of each star for each
step.
So, for example 2 above, the stars will not be completely highlighted
as desired. It is therefore important you set the configuration of
stars, min, max, and step correctly.
Refer the plugin documentation and demos for details.
for You:
'stars' => 4,
'step' => 3.75,
'min' => 0,
'max' => 15,
or
echo StarRating::widget(['name' => 'rating',
'pluginOptions' => [
'stars' => 5,
'step' => 3.75,
'min' => 0,
'max' => 18.75,
'starCaptions' => new JsExpression("function(val){return val-3.75 + ' hearts';}")
]
]);

If your field values are integers 1 to 5
To display half stars and full stars, You must use round numbers.
After putting the numbers in the following formula:
(max - min) * step * 100 / stars
Equal to: 50% or 100%
And to display only a full star, Equal to: 100%

However, it is better that the rate and step are equal.
For example, if step is 2, is better than max equal to 10 (5 Stars)

All of this varies according to the value of your field:
for example:
values: .5, 1, 1.5 , ... 5
Default (stars=5,max=5,step=0.5)
values: 1, 2, 3 , ... 5
(stars=5,max=5,step=1)
values: 1, 2, 3 , ... 12
(stars=6,max=12,step=1) => Half star = one point
values: 2, 4, 6 , ... 12
(stars=6,max=12,step=1) => one star = 2 point
