你如何在代码点火器中将图像上传到数据库中？

Question

我一直在尝试将图像上传到我的数据库（注意：我使用的是 Codeigniter 3）但是每次我尝试将图像上传到数据库时，它都不会存储它的文件名和图像本身，并且只存储 1 位在 BLOB var 类型中。

$photo = file_get_contents($_FILES['image']['tmp_name];

this->db->select('*')

[...]

if(empty($response){

   $data['entry_phone_no'] = $this->input->post('phone_no');

   $data['entry_email'] = $this->input->post('email');

   $data['entry_firstname'] = $this->input->post('first_name');

   $data['entry_lastname'] = $this->input->post('last_name');

   $data['entry_photo'] = $photo;

   $data['entry_photo_name'] = $photo;

在我的 model.php 中，我有上面的设置，它保存了其他数据（电话号码、电子邮件等）。我知道我在这"$photo"部分遗漏了一些代码，但有人可以指出吗？

您可以将图像上传到名为“Uploads”的文件夹中，并将该文件名保存到数据库中，如下所示：视图.php：<input class="my-set_3" type="file" name="chatbot_profile" id="chatbot_profile" required>控制器.php：if (!empty($_FILES['chatbot_profile']['name'])){&nbsp; $config['upload_path']&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = './uploads';&nbsp; $config['allowed_types']&nbsp; &nbsp; &nbsp; &nbsp; = 'gif|jpg|png';&nbsp; $config['max_size']&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 1000000;&nbsp; $config['file_name']&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;=&nbsp; time();&nbsp; $this->load->library('upload', $config);&nbsp; if ( ! $this->upload->do_upload('chatbot_profile'))&nbsp; {&nbsp; &nbsp; &nbsp; $error = array('error' => $this->upload->display_errors());&nbsp; }&nbsp; else&nbsp; {&nbsp; &nbsp; &nbsp; $data = array('upload_data' => $this->upload->data());&nbsp; &nbsp; &nbsp; $file_name = $data['upload_data']['file_name'] ;&nbsp; &nbsp; &nbsp; // Store this filename into database&nbsp; &nbsp; &nbsp; // Your database code will be placed here&nbsp; &nbsp; &nbsp; // OR call model&nbsp; mathod from here&nbsp; }}注意：uploads 文件夹将由我们在应用程序文件夹之外创建
