Codeigniter enctype=“multipart/form-data” 未正确保存照片

Question

Codeigniter当我在注册表单中使用enctype=“multipart/form-data”时，照片不会保存在数据库中，而是照片会上传到上传文件夹。然后当我删除enctype=“多部分/表单数据”照片保存在数据库中，但照片不来上传文件夹。如果这是代码的问题，请执行完整代码。因为我不是一个好的开发人员。

视图

<form method="post" action="family_join" enctype="multipart/form-data" id="wizard">

    <h4 class="text-center mb-4 mt-4">Upload Photo</h4>

    <div class="form-group mt-3 mb-4">

        <div class="dropzone-wrapper">

            <div class="dropzone-desc">

                <i class="glyphicon glyphicon-download-alt"></i>

                <p>Choose an image file or drag it here.</p>

            </div>

            <input type="file" name="photo" class="dropzone">

        </div>

    </div>

    <h4 class="text-center mb-4">Please enter the zipcode</h4>

    <div class="default-form contact-form">

        <div class="form-group">

            <input type="text" name="zipcode" placeholder="Enter Zip Code" required>

        </div>

    </div>

</form>

控制器

            $photo=$this->input->post('photo');

            $status = 1;

            $this->load->model('Family_Join_Model');

            $config['upload_path'] = './uploads/';

            $this-> Family_Join_Model->insert($zipcode, $photo, $status);

Answer 1

首先上传文件，然后从上传的文件数据中获取文件名。&nbsp; &nbsp; &nbsp; &nbsp; $config['upload_path'] = './uploads/';&nbsp; &nbsp; &nbsp; &nbsp; $config['allowed_types'] = 'gif|jpg|png';&nbsp; &nbsp; &nbsp; &nbsp; $this->load->library('upload', $config);&nbsp; &nbsp; &nbsp; &nbsp; if ($this->upload->do_upload('photo')) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $file_details = $this->upload->data();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $photo = $file_details['file_name'];&nbsp; &nbsp; &nbsp; &nbsp; } else {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $file_upload_msg = $this->upload->display_errors('<p>', '</p>');&nbsp; &nbsp; &nbsp; &nbsp; }

Answer 2

发生这种情况是因为当您将 enctype 设置为多部分/表单数据时，您的输入将作为二进制文件发送到服务器，并且二进制文件无法插入到数据库中。要将文件名插入到数据库中，请执行以下步骤。保持 enctype=multipart/form-data（这样你的文件就会上传到服务器）替换此行 ：$this->Family_Join_Model->插入（$zipcode， $photo， $status）;与这些：$upload_data&nbsp;=&nbsp;$this->upload->data();&nbsp; $this->Family_Join_Model->insert($zipcode,&nbsp;$upload_data['file_name'],&nbsp;$status);

$this->upload->do_upload('photo');$upload_data = $this->upload->data();$this->Family_Join_Model->insert($zipcode, $upload_data, $status);**Model**publicfunction insert($zipcode, $upload_data, $status) {&nbsp; &nbsp; $data = array(&nbsp; &nbsp; &nbsp; &nbsp; 'zipcode' => $zipcode,&nbsp; &nbsp; &nbsp; &nbsp; 'photo' => $upload_data['file_name'],&nbsp; &nbsp; &nbsp; &nbsp; 'isActive' => $status&nbsp; &nbsp; );&nbsp; &nbsp; $sql_query=$this->db->insert('tblfm', $data);&nbsp; &nbsp; if ($sql_query) {&nbsp; &nbsp; &nbsp; &nbsp; $this->session->set_flashdata('success', 'Registration successfull');&nbsp; &nbsp; &nbsp; &nbsp; redirect('user/family_join');&nbsp; &nbsp; } else {&nbsp; &nbsp; &nbsp; &nbsp; $this->session->set_flashdata('error', 'Somthing went worng. Error!!');&nbsp; &nbsp; &nbsp; &nbsp; redirect('user/family_join');&nbsp; &nbsp; }}
