Question

我使用以下代码成功地将表单的所有详细信息插入到数据库中。我的图片也上传到我的上传文件夹，但这些图片名称没有插入数据库图片字段。请告诉我我在哪里做错了。 FYR：我注意到错误发生在数据发布到数据库之前我使用foreach函数进行图像上传，所以那里发生了一些事情

mystruct test;
test.initial();
{
    std::ofstream ofs("filename.dat");
    boost::archive::text_oarchive ar(ofs);
    ar & test;
}
{
    std::ifstream ifs("filename.dat");
    boost::archive::text_iarchive ar(ifs);
    mystruct restored;
    ar & restored;
}

//this is my view code

移动此行：

$data= $this->input->post();

在foreach ($_FILES... )之前，$data变量不会被覆盖。

并将$data[$field_values]更改为$data[$field_name]，所以它会是这样的：

if ($this->form_validation->run()) {
    ...
    $data = $this->input->post();
    foreach ($_FILES as $field_name => $field_values) {
        if (!in_array($field_name, $expected_files)) {
            continue; // just in case user tries to add more upload fields
        }
        $this->upload->do_upload($field_name);
        $info = $this->upload->data();
        $image_path = $info['raw_name'] . $info['file_ext'];
        $data[$field_name] = $image_path; // change this line from using $field_values
    }
    ...
}
