Question

我正在创建一个多步骤表单，我正在努力将ID传递给表单的每一步，下面是我的代码

    function add_career() {
    $data = array();
    $this->load->model('admin_model');
    $this->load->library('form_validation');

        if($this->input->post('career_set') == 'Save') {

            $this->form_validation->set_rules('career_name', 'Career name', 'required|min_length[3]');
            $this->form_validation->set_rules('career_desc', 'Career description', 'required|max_length[3000]');
            $this->form_validation->set_rules('useful_info', 'Useful Information', 'max_length[1000]');
            $this->form_validation->set_rules('useful_links', 'Useful Links', 'max_length[1000]');
            if ($this->form_validation->run() == FALSE) {
               $this->template->build('admin/add_career'); 
            } else {
               if($this->input->post('degree_needed')) {
                   $degree_needed = 'Yes';
               } else {
                   $degree_needed = 'No';
               }

               $this->load->model('careers');
               $insertCareer = $this->careers->save(
                 $this->input->post('career_name'),
                 $this->input->post('career_desc'),
                 $degree_needed,
                 $this->input->post('useful_info'),
                 $this->input->post('useful_links')
               );

                   //save the data in the session, so we can to it if need be


                $this->career_id = $this->db->insert_id;
                $this->session->set_userdata($insertCareer);
                //$this->firephp->log($this->session->userdata($this->career_id, 'Career ID'));        
               }
        }

        $this->career_id = $this->db->insert_id();
        if($this->input->post('salary_set') == 'Save') {

                $this->firephp->log($this->career_id);
                $this->form_validation->set_rules('basic_salary', 'Basic salary', 'required|max_length[12]');
                $this->form_validation->set_rules('trained_salary', 'Fully trained salary', 'required|max_length[12]');
                $this->form_validation->set_rules('progressed_salary', 'Progressing onto salary', 'required|max_length[12]');
                $this->form_validation->set_rules('average_salary', 'Average salary', 'required|max_length[12]');

                if ($this->form_validation->run() == FALSE) {
                        $this->template->build('admin/add_career'); 
                } else {
                    $this->load->model('salaries');
                    $insertSalary = $this->salaries->save(
                        $this->input->post('basic_salary'),
                        $this->input->post('trained_salary'),
                        $this->input->post('progressed_salary'),
                        $this->input->post('average_salary'),
                        $this->career_id
                    );

                $this->session->set_userdata($insertSalary);
                $this->firephp->log($insertSalary);    
                }
        }

        if($this->input->post('course_grades_set') == 'Save') {
            //first off we need to save the grade details

            $this->load->model('grades');
            $this->load->model('course');
            $this->firephp->log(count($_POST['grade_desc']));

            foreach ($_POST['grade_desc'] as $k => $v) {
                $this->firephp->log($v, 'Looped Results');
                $insertGrade = $this->grades->save($v, $this->session->userdata('career_id'));
                // theorertically we should be able to save the assicated course at the same time using $k
                $insertCourse = $this->course->save(
                    $_POST['course_type'][$k],
                    $_POST['course_names'][$k], 
                    $_POST['course_links'][$k],
                    $this->db->insert_id()
                );
                $this->firephp->log($insertGrade, $k);
                $this->firephp->log($insertCourse, $k);
            }
            //$insertGrades = $this->grades->save()
            //);
        }




   $this->template->build('admin/add_career', $data);
}

我需要从保存职业的部分获取最后插入的id，并将其传递到保存工资细节的下一步，此刻，我得到的只是一个空变量。我是$this->career_id;

如果有人能解释如何将最后插入的id插入到表单的最后一部分。

非常感谢

Answer 1

首先，我想你使用$ this-＆gt; db-＆gt; insert_id来检索数据库中最后插入的id。您使用2个不同的调用来获取最后一个插入ID。第一个：

$ this-＆gt; career_id = $ this-＆gt; db-＆gt; insert_id;

第二个：

$ this-＆gt; career_id = $ this-＆gt; db-＆gt; insert_id（）;

我建议您在第二次通话时使用会话来检索carrer id。

另外，save方法返回什么（对于所有模型）？

Answer 2

我认为变量$this->db在此函数/类中不可用。

如果您要在课程$this->db->insert_id();中记录careers的输出，请{i} {}，那么您将获得正确的ID。我很确定此功能适用于您的save
