php - 如何在sql php中通过外键关系将数据插入到两个表中

Question

我有两个表目标，goalscore。

goals table fields(GoalId,UserId,GoalName,StartDate,EndDate).

GoalId 是主键(自动增量)。

在goalscore表中

(GoalScoreId、GoalId、GoalExpected、GoalAchieve、分数)

 GoalScoreId(primarykey(auto increment)) GoalId(foreign Key from goals)

现在我想将同一表单中的数据插入到两个表中。 第一个目标表，我想从该表中获取 GoalId，并根据该表，需要将同一目标的相关数据插入到 goalscore 表中。

有时我使用for循环向表中插入多个数据。所以最后插入的 id 我不能接受。有什么选择吗？

请帮我找到解决方案。

代码已给出

public function AddNewGoal(){
$userid=$this->session->userdata['loggedin']['userId'];

$Cdate=date('Y-m-d');
$Ldate=date('Y-m-d');
$date = $this->input->post('sdate');
//$freq = $this->input->post('frequency');
$freq= 1;
$kpiId= $this->input->post('kpiname');
$goal = $this->input->post('Goal');
$goaltype = $this->input->post('goaltype');
$targetscore = $this->input->post('target');

$yearEnd = date('Y-m-d', strtotime('12/31'));
//echo $yearEnd; exit();


$mnth= date('m', strtotime('-1 month'));
$m = 12- $mnth;
$q = 12-$mnth;

If($freq==1){
    $i=1;
    While ($i<= $m)
    {
        $query = $this->db->query('INSERT INTO goals
        (UserId,KPITTemplateItemId,GoalTypeId,GoalStatusId,GoalDesc,StartDate,EndDate,CreatedOn,CreatedBy,LastModifiedOn,LastModifiedBy)
        VALUES
        (180,1,1,4,"goal","'.$date.'","'.$date.'","'.$date.'","'.$userid.'","'.$date.'","'.$userid.'")');
        $i++;



    }



}
else if($freq==2){



}
else if($freq==3){



}
else if($freq==4){




}
else if($freq==5){

    $query = $this->db->query('INSERT INTO goals
        (UserId,KPITTemplateItemId,GoalTypeId,GoalStatusId,GoalDesc,StartDate,EndDate,CreatedOn,CreatedBy,LastModifiedOn,LastModifiedBy)
        VALUES
        (180,1,1,4,"goal","'.$date.'","'.$date.'","'.$date.'","'.$userid.'","'.$date.'","'.$userid.'")');


}

if($this->db->affected_rows() > 0){
    return true;
}else{
    return false;
}

}

您可以在 mysql 中使用函数last_inserted_id来实现此目的。
