插入数据 URL/链接输入与图像上传的代码点火器匹配 - Inserting Data URL/Link Input Matches Image Uploaded Codeigniter

在我的上传表单上，我有多个链接和用户文件。我希望能够插入与该表行上的图像匹配的链接/url，到目前为止，我尝试过的方法还没有奏效。我已经将链接和用户文件放入图像上传的数组中。

在我的控制器中，您将能够看到我为模型测试的内容。

我想知道什么是最好的，以便当用户在插入数据库时选择图像时，url/链接输入的输入将与图像文件名匹配

提前谢谢。如果你决定投反对票，你能告诉我为什么欢呼吗！

$upload_infos = $this->upload->data();
foreach ($upload_infos as $upload_info) {
$data = array(
'image' => $upload_info['file_name'],
//'link' => $this->input->post('link')

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

}

在我看来，

因为链接和图像在数组中，我不得不做一个额外的count($_POST['link']);对于链接和图像，我必须这样做$filename = $files['userfile']['name'][$i];成功是其中的一部分。

在阅读了更多 php 手册后，我花了一段时间才弄清楚，现在这段代码适用于多个上传也。
