Php 在codeigniter中，可以在一个表单中为不同的图像上传提供多个输入/浏览文件，以便将所有文件都保存在一个db中？

我是这里的新手，我的研究项目非常需要帮助。我不知道如何使用codeigniter将多个图像上传到数据库中的不同字段。在过去的几天里，我尝试了很多方法，但还是失败了

我的问题是，在codeigniter中，可以在一个表单中为图像按钮提供多个输入/浏览文件，以便将所有内容保存在数据库的一个表中。我有两个文本字段，我想为每一个不同的图像。我想用第一个文本框保存一个或多个图像，用第二个文本框保存一个或多个图像

我当前的错误是只有1个图像成功上传到字段，另一个字段为空

我的控制器：

public function create(){
    //form validation sebelum mengeksekusi QUERY INSERT
    $this->form_validation->set_rules('nama', 'Nama Property', 'required');
    $this->form_validation->set_rules('deskripsi_singkat', 'Deskripsi Singkat', 'required');

为此使用jquery，也可以使用select2或Selected库。请参阅如何使用select2进行多输入：

---

如果您知道如何使用jquery和基本php，您将可以做到这一点。

你面临什么问题？有错误吗？我想这会对你有帮助。那些链接没有解决我的问题，先生。。但是谢谢@KevalRathi@IndrasinhBihola我当前的错误是只有1个图像成功上传到字段，另一个字段为空。您面临什么问题？有错误吗？我想这会对你有帮助。那些链接没有解决我的问题，先生。。但是谢谢@KevalRathi@IndrasinhBihola我当前的错误是只有1个图像成功上传到字段，另一个字段为空。
