Question

我是编码的新手，我需要一些帮助，如何在添加学生时进行验证，它会提示学生已经存在，我在这里有一个示例代码来创建学生和更新。但我不知道如果学生已经存在，当我添加一个具有相同全名的学生时，如何验证它。如果电子邮件已经存在，我也需要验证我的电子邮件..

提前谢谢..希望你帮了我很多..：D

function student($param1 = '', $param2 = '', $param3 = '')
{
    if ($this->session->userdata('admin_login') != 1)
        redirect('login', 'refresh');
    if ($param1 == 'create') {
        $data['name']        = $this->input->post('name');

Answer 1

请用这个。

$firstName  = $this->input->post('firstName');
$lastName   = $this->input->post('lastName');

$checkStudentExists = $this->db->get_where('student', array('lastName' => $lastName, 'firstName' => $firstName);

if(count($checkStudentExists) > 0) {
  echo "Student already exists. Please enter another.";
} else {
# Do your code
}

希望它有所帮助。他们有许多姓氏和名字共存，请添加中间名或生日进行验证

Answer 2

如果全名已经存在，我会问我的验证码是否正确..

$name  = $this->input->post('name');

$checkFullnameExists = $this->db->get_where('student', array('name' => $name,);
if(count($checkStudentExists) > 0) {
$this->session->set_flashdata('flash_message', get_phrase('Student is already exists'));
} else {
#do your code
}

如果电子邮件已经存在，我还需要验证电子邮件还有一件事......非常感谢@Shudmeyer ......
