Codeigniter表单验证检查重复的许多条件

如果我考虑这样的条件,在codeigniter表单验证库中是否有一种方法可以确定人员数据的重复条目: 名字,中间名,姓氏,出生日期在数据库中匹配。

例如,如果数据与被认为相同的数据库匹配,我需要检查此人是否已存在:名字,中间名,姓氏和出生日期。

在这种情况下,我无法使用is_unique每种输入类型,因为如果此人具有相同的名字,姓氏和中间名,但生日数不同,该怎么办?如何在codeigniter中进行这样的表单验证?。

像这样的查询:

SELECT COUNT(patient_id) AS patient_id FROM patients WHERE patients.firstname = "" AND patients.middlename = "" AND patients.lastname = "" AND patients.birthdate = ""

如果查询结果大于1,则将其视为重复条目。我怎样才能在codeigniter表格验证中做到这一点?

这是我在Controller中的代码:

public function addpatient() {

         $this->form_validation->set_rules('pafname', 'pafname', 'trim|required',
            array('required' => 'First name is required')
            );

          $this->form_validation->set_rules('pamname', 'pamname', 'trim|required',
            array('required' => 'Middle name is required')
            );

          $this->form_validation->set_rules('palname', 'palname', 'trim|required',
            array('required' => 'Last name is required')
            );

          $this->form_validation->set_rules('paaddress', 'paaddress', 'trim|required',
            array('required' => 'Address is required')
            );

          $this->form_validation->set_rules('pacontact', 'pacontact', 'trim|required',
            array('required' => 'Contact # is required')
            );

          $this->form_validation->set_rules('pabdate', 'pabdate', 'trim|required',
            array('required' => 'Birthdate is required')
            );

          $this->form_validation->set_rules('psex', 'psex', 'trim|required',
            array('required' => 'Gender is required')
            );

          $this->form_validation->set_rules('pmartialstat', 'pmartialstat', 'trim|required',
            array('required' => 'Martial status is required')
            );

            if ($this->form_validation->run() == TRUE) {

                    $result['status'] = true;
                    $result['message'] = "This patient has no duplicate";
            }else {
                $result['status'] = false;

                $result['message'] = $this->form_validation->error_array();
            }
            echo json_encode($result);
    }

创建自己的custom validation method。在自定义验证方法中,调用SQL以查看是否存在所有字段匹配的记录,并根据匹配返回TRUE / FALSE。

类似的东西:

$this->form_validation->set_rules('pafname', 'pafname', 'trim|required|callback__duplicate_validation',
        array('required' => 'First name is required',
              'callback__duplicate_validation' => 'Duplicate record')
        );

function _duplicate_validation($pafname) {
    // Get _POST data for all fields since only pafname is passed in
    // Call SQL to see if duplicate
    // if duplicate, return FALSE
    // else return TRUE
}
