您好，我正在尝试通过上传 CSV 将数据插入 mysql 表。但我收到一个错误。上传显示错误并仅插入 ID 和日期。我不知道可能的原因。首先，我将用户表从 MYSQL 导出为 csv 格式。现在我使用我的代码上传相同但不起作用下面是我的代码:

我做了 Print_r($file_data); 所以得到这个

Array ( [file_name] => users_(2)3.csv [file_type] => text/plain [file_path] => /var/www/Test/uploads/ [full_path] => /var/www/Test/uploads/users_(2)3.csv [raw_name] => users_(2)3 [orig_name] => users_(2).csv [client_name] => users (2).csv [file_ext] => .csv [file_size] => 3.83 [is_image] => [image_width] => [image_height] => [image_type] => [image_size_str] => )

Controller :

    function importcsv() {
    $data['users'] = $this->csv_m->get_users();
    $data['error'] = '';    //initialize image upload error array to empty


    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'csv';
    $config['max_size'] = '1000';

    $this->load->library('upload', $config);


    // If upload failed, display error
    if (!$this->upload->do_upload()) {
        $data['error'] = $this->upload->display_errors();
        print_r($_FILES);

        $this->load->view('csv', $data);
    } else {


        $file_data = $this->upload->data();
        $file_path =  './uploads/'.$file_data['file_name'];

        if ($this->csvimport->get_array($file_path))
         {
            $csv_array = $this->csvimport->get_array($file_path);

            foreach ($csv_array as $row)
             {
                $insert_data = array(

                    'id'=>$row['id'],
                    'sip_id'=>$row['sip_id'],
                    'sip_pass'=>$row['sip_pass'],
                    'key'=>$row['key'],
                    'name'=>$row['name'],
                    'status'=>$row['status'],
                    'email'=>$row['email'],
                    'password'=>$row['password'],
                    'phone'=>$row['phone'],
                    'balance'=>$row['balance'],
                    'created'=>$row['created'],
                    'modified'=>$row['modified'],
                    'date_inactive'=>$row['date_inactive'],
                    'reset_date'=>$row['reset_date'],


                );

                print_r($file_data);

                $this->csv_m->insert_csv($insert_data);
            }
            $this->session->set_flashdata('success', 'Csv Data Imported Succesfully');
            redirect(base_url().'csv');
            //echo "<pre>"; print_r($insert_data);
        } else 
            $data['error'] = "Error occured";
            $this->load->view('csv', $data);
        }


    }

模型:

<?php

class Csv_m extends CI_Model {

function __construct() {
    parent::__construct();

}

function get_users() {     
    $query = $this->db->get('users');

    if ($query->num_rows() > 0)
     {
        return $query->result_array();
    } 
    else 
    {
        echo"Nothing To Show";
        return FALSE;
    }
}

function insert_csv($data) {
    $this->db->insert('users', $data);
}

View :

   <?php if (isset($error)): ?>
            <div class="alert alert-error"><?php echo $error; ?></div>

请检查我的代码并帮助我解决这个问题。当我上传 csv 时出现错误:

Message: Undefined index: id Message: Undefined index: sip_id Message: Undefined index: sip_pass

和所有其他字段。但是有些 id 和 date 是如何插入到表中的，而其他字段却没有!

我面临的错误:

最佳答案

如果您的模型返回 false，则用户 $users 数组为空。所以在 View 中你有你检查空

<?php if (!empty($users)): ?>// check empty array
    <tr><td colspan="4">There are currently Users</td></tr>
<?php else: ?>
    <?php foreach ($users as $row): ?>
        <tr>
            <td><?php echo $row['id']; ?></td>
            <td><?php echo $row['sip_id']; ?></td>
            <td><?php echo $row['sip_pass']; ?></td>
            <td><?php echo $row['key']; ?></td>
            <td><?php echo $row['name']; ?></td>
            <td><?php echo $row['status']; ?></td>
            <td><?php echo $row['email']; ?></td>
            <td><?php echo $row['password']; ?></td>
            <td><?php echo $row['phone']; ?></td>
            <td><?php echo $row['balance']; ?></td>
            <td><?php echo $row['created']; ?></td>
            <td><?php echo $row['modified']; ?></td>
            <td><?php echo $row['date_inactive']; ?></td>
            <td><?php echo $row['reset_date']; ?></td>
        </tr>
    <?php endforeach; ?>
<?php endif; ?>
