Laravel excel，迭代项目以插入数据

Question

我的 excel 文件由我保存在数据库中的 student id, name, and course 组成。数据按性别分开，其中row[0]。我在这里想要实现的是如何迭代我的数据并在我的数据库中插入性别。？

示例sample.xlsx

//StudentController
Excel::import(new StudentsImport, request()->file('import'));

//ImportSheet
public function model(array $row)
    {
        //empty rows
        if (!isset($row[1]) || $row[0] == '#') {
            return null;
        }

        if (isset($row[1])) {
            return new Student([
                'id_number' => $row[1],
                'name' => $row[2],
                'course' => $row[3],
                'gender' => 'male || female', //<--- HOW CAN I INSERT GENDER HERE BASE ON THE JPEG ABOVE?
            ]);
        }
    }

这可以帮助您确定性别：

public function model(array $row)
{        
    //empty rows
    if (!isset($row[1]) || $row[0] == '#') {
        return null;
    }

    //get the gender
    $gender = ''; // default is empty, you can also assign some default value 
    if (isset($row[0]) && (strtolower($row[0]) == 'male' || strtolower($row[0]) == 'female')) {
        $gender = $row[0];
    }


    if (isset($row[1])) {
        return new Student([
            'id_number' => $row[1],
            'name' => $row[2],
            'course' => $row[3],
            'gender' => $gender
        ]);
    }
}
