codeigniter中的数组问题 [英] Array issue in codeigniter
本文介绍了codeigniter中的数组问题的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我做了一个桌子爱好,因为我拿了一个名为hid []的数组。
因为我通过了hid和hnm。
我有另一个桌子员工和我把隐藏作为外键。
当我从前端传递隐藏时:
hid:
[0] - > 1
[1] - > 2
[2] - > 3
当我从前端传递hnm时:
[0] - >阅读
[1] - >游泳
[2] - >跳舞

我尝试过:
我使用了Implode和Explode,因为hid是一个数组。
保存此数据后,我只能看到hid或hnm到视图屏幕。
我想将hid存储到我的数据库,hnm来查看屏幕。
帮我解决这个问题。
解决方案
this-> load-> database();
这 - >负载>模型( 'Employee_model');
这 - >负载>辅助( 'URL');
}
//保存数据
公共函数add()
{
I made a table hobby, in that i took an array named hid[].
In that i passed hid and hnm.
I have another table employee and I take hid as an foreign key.
When I passes the hid from front end as :
hid :
[0] -> 1
[1] -> 2
[2] -> 3
When I passes the hnm from front end as :
[0] -> Reading
[1] -> Swimming
[2] -> Dancing

What I have tried:
I used Implode and Explode because hid is an array. I can only see either hid or hnm to the view screen after save this data. I want to store hid to my database and hnm to view screen. help me with this.
解决方案
this->load->database();
this->load->model('Employee_model');
this->load->helper('url'); } //save data public function add() {
