【中文标题】Codeigniter 将部分 CSV 数据插入到 MYSQL 中,只有 id 和 date【英文标题】:Codeigniter inserts partial CSV data into MYSQL only id and date 【发布时间】:2015-12-15 03:46:30 【问题描述】: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); 所以得到了这个
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] => )
控制器:
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', $data);
观点:
<?php if (isset($error)): ?>
<div class="alert alert-error"><?php echo $error; ?></div>
<?php endif; ?>
<h2>CI Addressbook Import</h2>
<form method="post" action="<?php echo base_url() ?>csv/importcsv" enctype="multipart/form-data">

请检查我的代码并帮助我解决此问题。当我上传 csv 时出现错误:
消息:未定义的索引:id 消息:未定义的索引:sip_id 消息:未定义的索引: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,而其他字段则没有!
我面临的错误:
【问题讨论】:
查看查看if(!empty($users)) foreach ($users as $row):
我要改成这个吗?
是的,因为如果 return FALSE;
来自您的模型,则意味着您的 $users
数组为空
对吗?
我从模型代码中得到了这个 else 部分:Nothing To Show
【参考方案1】:
如果您的模型 return false
用户 $users 数组为空。所以在视图中你有你检查空
<?php if (!empty($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; ?>
【讨论】:
您好,这解决了空数组错误,但我的控制器或未定义 id、sip_id、sip_pass、key 的模型仍然出现错误....... 另外数据没有被导入mysqlprint_r( $csv_array)
并粘贴它的值
我得到了每条记录的数据库值数组
$csv_array = $this->csvimport->get_array($file_path);print_r( $csv_array)
【参考方案2】:
消息:未定义索引:id 消息:未定义索引:sip_id 消息:未定义索引:sip_pass
当变量未定义或没有相关数据时会发生此错误
确保您的 $users
数组名称与此名称一致
$row['id'];
$row['sip_id'];
$row['sip_pass'];
$row['key'];
$row['name'];
$row['status'];
$row['email'];
$row['password'];
$row['phone'];
$row['balance'];
$row['created'];
$row['modified'];
$row['date_inactive'];
$row['reset_date'];
并且在视图表中应该是
<table class="table table-striped table-hover table-bordered">
<caption>Address Book List</caption>
<thead>
<tr>
<th>Id</th>
<th>SIP Id</th>
<th>SIP Password</th>
<th>Key</th>
<th>Name</th>
<th>Status</th>
<th>Email</th>
<th>Password</th>
<th>Balance</th>
<th>Created</th>
<th>Modified</th>
<th>Date_Inactive</th>
<th>Date Reset</th>
</tr>
</thead>
<tbody>
<?php if (empty($users)) //use empty()
?>
<tr><td colspan = "4" > There are currently Users </td ></tr>
<?php
else
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
?>
</tbody>
</table>
在模型中
function get_users()
$query = $this->db->get('users');
$result = $query->result_array();
$count = count($result);
if (empty($count))
return $result;
else
