Question

我尝试使用zend框架连接到mysql数据库，但它无法连接。我跟进了zend文档以及一些关于如何连接到mysql的其他教程，但它在这一行上给了我一个错误＆＃34; $ sm = $ this-＆gt; getServiceLocator（）;＆＃ 34;

错误讯息：

Zend\ServiceManager\ServiceManager::get was unable to fetch or create an instance for Post\Model\PostTable

global.php

return array(
'db' => array(
    'driver' => 'Pdo',
    'dsn' => 'mysql:dbname=zend;host=localhost',
    'driver_options' => array(
        PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
    ),
),
'service_manager' => array(
    'factories' => array(
        'Zend\Db\Adapter\Adapter'
        => 'Zend\Db\Adapter\AdapterServiceFactory',
    ),
),);

local.php

 return array(
'db' => array(
    'username' => 'root',
    'password' => '',
),

）;

PostController.php

public function getPostTable() {
    if (!$this->postTable) {
        $sm = $this->getServiceLocator();
        $this->postTable = $sm->get('Post\Model\PostTable');
    }
    return $this->postTable;
}

//模块/后/ SRC /后/型号/ PostTable.php

<?php
namespace Post\Model;

use Zend\Db\Adapter\Adapter;
use Zend\Db\ResultSet\ResultSet;
use Zend\Db\TableGateway\AbstractTableGateway;

class PostTable extends AbstractTableGateway
{
  protected $table ='tbl_post';

   public function __construct(Adapter $adapter)
{
    $this->adapter = $adapter;
    $this->resultSetPrototype = new ResultSet();
    $this->resultSetPrototype->setArrayObjectPrototype(new Post());
    $this->initialize();
}

public function fetchAll()
{
    $resultSet = $this->select();
    return $resultSet;
}
}

Answer 1

我个人认为，很明显“Post \ Model \ PostTable”根本没有定义，或者它应该定义在哪里。

您的代码库中定义的'Post \ Model \ PostTable'在哪里？这与ZF2的规则相比如何？

Answer 2

在你的Module.php中你应该有＆＃39; Post \ Model \ PostTable＆＃39;注入表

祝你好运：）
