从多个相同的输入插入数据？

Question

如果我有多个相同的输入，我希望仍然能够将它们插入数据库而不会覆盖第一个 lot.I 已经试过了，但没有成功。我的框架使用 codeigniter。

我如何能够拥有多个相同的输入，但仍然在 table.

上为两者创建一个新行

尽管如此，我需要为所有人保留相同的横幅 ID。

如果您对问题投反对票，请解释为什么干杯

型号

public function add_banners_image($banner_id = 0) {

$data = array(
'banner_id' => $banner_id,
'link' => $this->input->post('link'),
);

$this->db->set($data);
$this->db->insert_id();
$this->db->insert($this->db->dbprefix . 'banner_image');

//return $this->db->insert_id();

}

控制器

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Banner_add extends Admin_Controller {

public function __construct() {
parent::__construct();
$this->load->model('admin/design/model_add_banners');
}

public function index() {
$this->load->library('form_validation');

$this->form_validation->set_rules('name', 'Banner Name');
$this->form_validation->set_rules('status', 'Banner Status');

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

return $this->load->view('design/banner_form.tpl', $data);

} else {

$banner_id = $this->model_add_banners->add_banners();

$banner_image_id = $this->model_add_banners->add_banners_image($banner_id);

$this->model_add_banners->admin_banners_banner_image_description($banner_image_id, $banner_id);

redirect('admin/design/banners');

}

}

}

首先，您应该将title 和link 的name 属性更改为title[] 和link[]。这允许在提交表单时发送同名的多个值。

然后，您必须分别读取所有值并进行相应处理。这是您模型的更改代码：

public function add_banners_image($banner_id = 0) {

$links = $this->input->post('link');
foreach ($links as $link) {
    $data = array(
        'banner_id' => $banner_id,
        'link' => $link,
    );

    $this->db->set($data);
    $this->db->insert_id();
    $this->db->insert($this->db->dbprefix . 'banner_image');

    //return $this->db->insert_id();
}

}

这里是对在 codeigniter 中 "POST" 中接收到的处理数组值的引用： Getting data from post array in CodeIgniter
