我在Codeigniter中有1054错误,我不知道为什么。我想创建一个登录表单并检查用户是否已登录。
但我只创建一个简单的视图和控制器,并显示以下错误:
Error Number: 1054
Unknown column 'user_data' in 'field list'
INSERT INTO `ci_sessions` (`session_id`, `ip_address`, `user_agent`, `last_activity`, `user_data`) VALUES ('c392322ac31b7fac1c2d79cfbde9edf7', '127.0.0.1', 'Opera/9.80 (Windows NT 6.1) Presto/2.12.388 Version/12.15', 1368010716, '')
Filename: C:\wamp\www\..\system\database\DB_driver.php
Line Number: 330
我只用这个脚本创建了表会话:
CREATE TABLE IF NOT EXISTS `ci_sessions` (
session_id varchar(40) DEFAULT '0' NOT NULL,
ip_address varchar(45) DEFAULT '0' NOT NULL,
user_agent varchar(50) NOT NULL,
last_activity int(10) unsigned DEFAULT 0 NOT NULL,
PRIMARY KEY (session_id)
);
观点:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Anuncios</title>
<link rel="stylesheet" href="/Pruebas/css/estilos.css" type="text/css"
media="screen"/>
</head>
<body>
<div id="contenedor">
<div id="menu">
<label for="home" id="inicio"><a href="http://localhost/Pruebas/index.php/
cindice/">Inicio</a></label>
<label for="acceso" id="login"><a href="http://localhost/Pruebas/index.php/
cindice/publicar">Publicar anuncio</a></label>
<label for="reg" id="registro"><a href="http://localhost/Pruebas/index.php/
cindice/registro">Registro</a></label>
<label for="empresa" id="sobrempresa"><a href="http://localhost/Pruebas/
index.php/cindice/sobempresa">Sobre nosotros</a></label>
<label for="contacto" id="contactar"><a href="http://localhost/Pruebas/
index.php/cindice/contacto">Contáctanos</a></label>
</div>
</div>
</body>
</html>
控制器:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Cindice extends CI_Controller {
function __construct() {
parent::__construct();
}
public function index()
{
$this->load->view('indice');
}
public function publicar()
{
echo "Aquí se publica el anuncio";
}
public function acceso()
{
echo "Esto es el acceso";
}
}
?>
如何解决此问题?
感谢。
答案 0 :(得分:2)
manual表示你的ci_sessions表应该像这样创建:
CREATE TABLE IF NOT EXISTS `ci_sessions` (
session_id varchar(40) DEFAULT '0' NOT NULL,
ip_address varchar(45) DEFAULT '0' NOT NULL,
user_agent varchar(120) NOT NULL,
last_activity int(10) unsigned DEFAULT 0 NOT NULL,
user_data text NOT NULL,
PRIMARY KEY (session_id),
KEY `last_activity_idx` (`last_activity`)
);
请注意表格中缺少的“user_data”字段。
