php - 如何在两个不同的表中同时插入值

Question

表1:主题大师

id | subjectcode | subjectname
------------------------------
1  | phy         | physics

表2:类(class)大师

id | coursecode | coursename
----------------------------
1  | bsc        | bachlore of science

表3:考试类(class)

id | examname | course_code
---------------------------
1 | semester  | bsc

表4:类(class)表

id | coursecode | coursename |  subjectcode | subjectname | examname
--------------------------------------------------------------------

型号:

function add_record($data)
{
    $this->db->insert('examcourse', $data);
    $this->db->insert('course_table', $data);
    return;
}

Controller :

function create()
    {
    $j=1;
     $createcustomer = $this->input->post('createcustomer');

         if( $this->input->post('createcustomer') != false ){

       foreach ($createcustomer as $j)
       {
            $data = array(
            'exam_name' => $this->input->post('exam_name_id'.$j),
            'course_code' => $this->input->post('course_code_id'.$j)
            );

            //$course_code= mysql_real_escape_string($_POST["course_code_id".$j]);
            $exam_name = $this->input->post('exam_name_id'.$j);
            if ($exam_name != ""){
            $this->examcourse_model->add_record($data, $exam_name);
            }
            $j++;

    }
    }
        $this->index();
    }

如果我点击插入表单，它只会在table3和table4中插入coursecode和examname
但我需要插入coursecode、coursename、subjectcode、subjectname、examname在表4中。

如何获取值并将其插入表中？

Answer 1

您的$data数组应将键作为course_table的列

$data=array(
'coursecode'=>'test',
'coursename'=>'test',
'subjectcode'=>'test,'
'subjectname'=>'test',
'examname'=>'test'
);

$this->db->insert('course_table', $data);

只需确保您使用正确的值和键创建了 $data 数组
