Description:

When my code have status include 0, the input filter don't work fine.

`

/**
 * Add a binding to the query.
 *
 * @param string     $value
 * @param Model|null $model
 */
public function addBinding($value, Model $model)
{
    if (empty($value)) {  // when value is string "0" will not work fine
        return;
    }

    if ($this->type == 'like') {
        $model->where($this->getColumnName(), 'like', "%{$value}%");

        return;
    }

    if (in_array($this->type, ['date', 'time'])) {
        $method = 'where'.ucfirst($this->type);
        $model->{$method}($this->getColumnName(), $value);

        return;
    }

    $model->where($this->getColumnName(), $value);
}

`

so and now , fix it to

`

/**

• Add a binding to the query.
• @param string $value

• @param Model|null $model */ public function addBinding($value, Model $model) {

  if (empty($value)) {
      //return;
  }
  
  if($value==NULL) {
      return ;
  }
  
  if ($this->type == 'like') {
      $model->where($this->getColumnName(), 'like', "%{$value}%");
  
      return;
  }
  
  if (in_array($this->type, ['date', 'time'])) {
      $method = 'where'.ucfirst($this->type);
      $model->{$method}($this->getColumnName(), $value);
  
      return;
  }
  
  $model->where($this->getColumnName(), $value);

  }

`
