codeigniter - 更改下载文件名 codeigniter

Question

在强制下载之前转换文件名。

我试图在下载之前将存储的文件名转换为原始文件名

因此，当用户单击要下载的文件而不是显示时

post_1486965530_jeJNHKWXPMrwRpGBYxczIfTbaqhLnDVO.php

如下图所示

它只会重命名下载的文件，例如

config.php

Question how to only change the downloaded filename when click on image.

public function downloads($id) {
    $this->db->where('attachment_id', $id);
    $query = $this->db->get('attachments');

    if ($query->num_rows() == 0) {
       return false;
    }

    $path = '';
    $file = '';

    foreach ($query->result_array() as $result) {

        $path .= FCPATH . 'uploads/'; 

        // This gives the stored file name
        // This is folder 201702
        // Looks like 201702/post_1486965530_jeJNHKWXPMrwRpGBYxczIfTbaqhLnDVO.php

        $stored_file_name .= $result['attachment_name']; 

        // Out puts just example "config.php"
        $original .= $result['file_name']; 

    }

    force_download($path . $stored_file_name, NULL);
}

那怎么样 (恕我直言，你的 foreach 循环没有任何意义)

public function downloads($id) {
    $this->db->where('attachment_id', $id);
    $query = $this->db->get('attachments');

    if ($query->num_rows() == 0) {
       return false;
    }

    $path = '';
    $file = '';

    foreach ($query->result_array() as $result) {

        $path .= FCPATH . 'uploads/'; 

        // This gives the stored file name
        // This is folder 201702
        // Looks like 201702/post_1486965530_jeJNHKWXPMrwRpGBYxczIfTbaqhLnDVO.php

        $stored_file_name .= $result['attachment_name']; 

        // Out puts just example "config.php"
        $original .= $result['file_name']; 

    }

    force_download("your_filename.txt",file_get_contents($path . $stored_file_name));
}
