在Codeigniter 3发布之后,从这个
tutorial发布
我有一些问题
我想使用Eloquent并执行此步骤
>安装Composer
>使用此json文件安装依赖项
{
"require": {
"illuminate/database": "4.2.6"
},
"autoload": {
"classmap": [
"application/core",
"application/models",
"application/libraries"
]
},
"config": {
"vendor-dir": "vendor/"
}
}
>成功安装
>在下面进行一些配置:
一个.更新autoload.php =>上的库$autoload [‘libraries’] = array(‘database’);
湾update config.php => $config [‘composer_autoload’] = TRUE;
C.更新database.php
$active_group = 'default';
$query_builder = TRUE;
$db['default'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'ci3',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => TRUE,
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
use Illuminate\Database\Capsule\Manager as Capsule;
$capsule = new Capsule;
$capsule->addConnection(array(
'driver' => in_array($db['default']['dbdriver'], array('mysql', 'mysqli')) ? 'mysql' : $db['default']['dbdriver'],
'host' => $db['default']['hostname'],
'database' => $db['default']['database'],
'username' => $db['default']['username'],
'password' => $db['default']['password'],
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => $db['default']['dbprefix'],
)
);
$capsule->setAsGlobal();
$capsule->bootEloquent();
$events = new Illuminate\Events\Dispatcher;
$events->listen('illuminate.query', function($query, $bindings, $time, $name) {
// Format binding data for sql insertion
foreach ($bindings as $i => $binding) {
if ($binding instanceof \DateTime) {
$bindings[$i] = $binding->format('\'Y-m-d H:i:s\'');
} else if (is_string($binding)) {
$bindings[$i] = "'$binding'";
}
}
// Insert bindings into query
$query = str_replace(array('%', '?'), array('%%', '%s'), $query);
$query = vsprintf($query, $bindings);
// Add it into CodeIgniter
$db =& get_instance()->db;
$db->query_times[] = $time;
$db->queries[] = $query;
});
$capsule->setEventDispatcher($events);
d.创建一个名为ci3和表用户的数据库而不是它
这是我的模特
<?php
if (!defined('BASEPATH')) exit('No direct script access allowed');
use \Illuminate\Database\Eloquent\Model as Eloquent;
class Users extends Eloquent {
protected $table = "users";
}
和我的控制器
<?php
if (!defined('BASEPATH')) exit('No direct script access allowed');
class User extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->model('users');
}
public function index($page = 1) {
$users = Users::all();
foreach ($users as $user) {
echo '<li>' . $user->username . '</li>';
echo '<li>' . $user->password . '</li>';
echo '<li>' . $user->email . '</li>';
}
echo '</ul>';
}
}
这是我的错误报告
Fatal error: Class ‘Illuminate\Database\Capsule\Manager’ not found in C:\xampp\htdocs\ci3\application\config\database.php on line 88
A PHP Error was encountered
Severity: Error
Message: Class ‘Illuminate\Database\Capsule\Manager’ not found
Filename: config/database.php

我不知道怎么放胶囊类
最佳答案 这是问题…你错过了laravel的’events’库,将以下行添加到你的composer.json:
“照亮/事件”:“5.0.28”
就我而言,我使用的是Laravel 5,所以,我的composer.json看起来像:
{
"require": {
"illuminate/database": "5.0.28",
"illuminate/events": "5.0.28"
}
}
请检查我是如何实施here的.
