[PHP知识库]magento2 简单使用

文章目录

magento2

magento2

m2的核心源代码通过composer install后，存放在vendor/magento里

db

在app/etc/文件夹下会多出config.php和env.php两个php文件，config.php可以看到magento2加载了那些模块；env.php保存了连接的数据库的一些信息

eav

1、eav_entity_type 表：
eav_entity_code：代表实体（表名）
attribute_model：实例化model
entity_table：实体所对应的最关键表（XXX_entity表）

2、eav_attribute 表：
eav_entity_id：关联eav_entity_type表
attribute_code：代表属性（字段名）

3、xxx_eav_atrribute 表：
eav_attribute 表的属性的具体设置

4、eav_entity_attribute 表：
作为 eav_entity_type 和 eav_attribute 的中间表

5、XXX_entity 表:
记录一条数据

6、XXX_entity_{type} 表：
记录 XXX_entity 数据的各个属性（字段）值

1、2、3、4为表结构设置表；
5、6为对应的“数据—值”表

search

1、时间（时区）格式化

$timezone = ObjectManager::getInstance()->get('Magento\Framework\Stdlib\DateTime\TimezoneInterface');
var_dump($timezone->date($sourceData)->format('Y-m-d H:i:s'));

CRUD

app/code/重写目录/重写插件/Setup/

1、update

<?php

namespace MxGenki\ProductList\Setup;

use Magento\Eav\Setup\EavSetup;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Framework\Setup\UpgradeDataInterface;

class UpgradeData implements UpgradeDataInterface
{

    private $eavSetupFactory;

    public function __construct(EavSetup $eavSetupFactory)
    {
        $this->eavSetupFactory = $eavSetupFactory;
    }
    
    //改变属性值
    public function upgrade(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        $setup->startSetup();
        $this->eavSetupFactory->updateAttribute(4,82,'is_visible', 0, null);
        $setup->endSetup();
    }
}

<?php


namespace MxGenki\ChooseStore\Setup;

use Magento\Framework\Setup\UpgradeSchemaInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\SchemaSetupInterface;
class UpgradeSchema implements UpgradeSchemaInterface
{
	// 改变表字段类型
    public function upgrade(SchemaSetupInterface $setup, ModuleContextInterface $context)
    {
        $setup->startSetup();

        if (version_compare($context->getVersion(), '2.0.2', '<')) {
            $setup->getConnection()->changeColumn(
                $setup->getTable('inventory_source'),
                'email',
                'email',
                [
                    'type' => \Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
                    'nullable' => false,
                    'default' => '',
                    'comment' => 'email'
                ]
            );
        }
        $setup->endSetup();

    }

}

2、add\delete

<?php
namespace MxGenki\Menu\Setup;

use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Exception\LocalizedException;
use Magento\Framework\Setup\{
    ModuleContextInterface,
    ModuleDataSetupInterface,
    InstallDataInterface
};

class InstallData implements InstallDataInterface
{
    private $eavSetupFactory;

    public function __construct(EavSetupFactory $eavSetupFactory) {
        $this->eavSetupFactory = $eavSetupFactory;
    }

    /**
     * @throws \Zend_Validate_Exception
     * @throws LocalizedException
     */
    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
		
		// 删除属性
        $eavSetup->removeAttribute(\Magento\Catalog\Model\Category::ENTITY, 'jpa_name');
        // 增加属性
        $eavSetup->addAttribute(\Magento\Catalog\Model\Category::ENTITY, 'jpa_name', [
            'group' => 'Display Settings',
            'type' => 'varchar',
            'backend' => '',
            'frontend' => '',
            'sort_order' => 10,
            'label' => 'Jpa name',
            'input' => 'text',
            'class' => '',
            'source' => '',
            'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_STORE,
            'visible' => true,
            'required' => false,
            'user_defined' => false,
            'default' => '',
            'searchable' => false,
            'filterable' => false,
            'comparable' => false,
            'visible_on_front' => false,
            'used_in_product_listing' => true,
            'apply_to' => ''
        ]);
    }
}

常用命令

在/magento目录下执行

1、数据库/模块变更

php bin/magento setup:upgrade

2、di.xml 依赖关系变更

php bin/magento setup:di:compile

3、强制部署静态文件（清楚缓存后）

php bin/magento setup:static-content:deploy -f
// 合并执行
rm -rf ./pub/static/*/* && sudo rm -rf ./var/view_preprocessed/* && sudo php bin/magento setup:static-content:deploy -f && sudo php bin/magento cache:clean && sudo chmod 777 var -R && sudo chmod 777 pub -R

清缓存

php bin/magento cache:clean

刷新缓存

php bin/magento cache:flush

删除缓存文件

sudo rm -rf ./pub/static/*/* && sudo rm -rf ./var/view_preprocessed/*

4、修改为开发模式

php bin/magento deploy:mode:set developer

5、禁用二重验证

php bin/magento module:disable Magento_TwoFactorAuth

layout

1、联动隐藏节点

重写插件

请添加图片描述
1、模块声明
app/code/重写目录/重写插件/etc/module.xml

File: app/code/MxGenki/ChooseStore/etc/module.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="MxGenki_ChooseStore" setup_version="1.0.0">
    </module>
</config>

name：module的名称
setup_version： module的版本号

2、注册模块
app/code/重写目录/重写插件/registration.php

File: app/code/MxGenki/ChooseStore/registration.php

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'MxGenki_ChooseStore',
    __DIR__
);

执行php bin/magento setup:upgrade命令后，可在app/etc/config.php查看到该激活模块

3、路由声明
app/code/重写目录/重写插件/etc/(adminhtml | frontend)/routes.xml

File: app/code/MxGenki/ChooseStore/etc/adminhtml/routes.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
    <router id="admin">
        <route id="admin_choose_store" frontName="admin_choose_store">
            <module name="MxGenki_ChooseStore"/>
        </route>
    </router>
</config>

<router>标签说明:

id = standard 表示前端路由;

<route>标签说明:

id : 对于router的唯一标识名;

frontName : 前端URL的控制名称;

<module>标签说明：

name : 声明module的名称;

before : 表示在定义module之前加载;

after : 表示在定义moduel之后加载;

备注：“before” et “after” 在创建module时不是必须的

4、创建控制器
app/code/重写目录/重写插件/Controller/(Adminhtml | Index)/xxx.php
请添加图片描述

<?php
namespace MxGenki\ChooseStore\Controller\Adminhtml\Source;

use Magento\Framework\Controller\ResultInterface;

class Save extends \Magento\InventoryAdminUi\Controller\Adminhtml\Source\Save
{
    const ADMIN_RESOURCE = 'Magento_InventoryApi::source_save';

    public function execute(): ResultInterface
    {
    	// ...
    }
}

再将di.xml的依赖关系改写，调用原有save方法时，将改调新的save方法

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/ObjectManager/etc/config.xsd">
    <preference for="Magento\InventoryAdminUi\Controller\Adminhtml\Source\Save" type="MxGenki\ChooseStore\Controller\Adminhtml\Source\Save" />
</config>

注意： 若改写的class文件在其他文件的__construct()构造方法中，则不能直接改变依赖。需将上一层的class文件的__construct()拓展。

<?php

namespace MxGenki\AmastyNotifications\Model;

use Amasty\PushNotifications\Model\Builder\NotificationBuilder;

// 将NotificationProcessor在di.xml改写依赖
class NotificationProcessor extends \Amasty\PushNotifications\Model\Processor\NotificationProcessor
{
    /**
     * @var NotificationBuilder
     */
    private $newNotificationBuilder;

    public function __construct(
        NotificationBuilder $notificationBuilder
    ) {
        parent::__construct(
            $notificationBuilder
        );
        // 重写NotificationBuilder注入，该类不需要再在di.xml改写依赖
        $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
        $this->newNotificationBuilder = $objectManager->get('MxGenki\AmastyNotifications\Model\NotificationBuilder');
    }

5、创建block
app/code/重写目录/重写插件/Block/(Adminhtml | Frontend)/xxx.php
真正与浏览器页面最相关的还是由对应的Block输出数据。

<?php
namespace MxGenki\ProductList\Block;

use Magento\Checkout\Model\Session;
use Magento\Framework\Exception\LocalizedException;
use Magento\Framework\Exception\NoSuchEntityException;
use Magento\Framework\View\Element\Template;

class IsInCart extends Template
{
    protected Session $_checkoutSession;
    public function __construct(
        Template\Context $context,
        Session $session,
        array $data = []
    )
    {
        $this->_checkoutSession = $session;
        parent::__construct($context, $data);
    }

    public function getCartProductQty($_product): int
    {
        $qty = 0;
        return $qty;
    }
}

第二种：单独引入js

<?php
namespace MxGenki\ChooseStore\Block\Adminhtml\Form;

class ApplyChange extends \Magento\Framework\View\Element\Template
{
    protected $_template = 'applyChange.phtml';
}

6、创建Layout布局文件
app/code/重写目录/重写插件/view(adminhtml | frontend)/layout/xxx.xml

布局文件的命名规则为：<Router Name>_<Controller Name>_<Action Name>

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>
    	<!-- template: module.xml配置的"name":: templates文件下的"路径"  -->
        <referenceBlock name="category.products.list" template="MxGenki_ProductList::product/list.phtml">
            <block class="MxGenki\ProductList\Block\IsInCart" name="genki_catalog_isincart" cacheable="false"/>
        </referenceBlock>
    </body>
</page>

第二种：单独引入js

		<container name="page_initialize" sortOrder="50">
            <htmlContent name="html_content">
                <block name="apply_change" class="MxGenki\ChooseStore\Block\Adminhtml\Form\ApplyChange"/>
            </htmlContent>
        </container>

7、创建模板文件
app/code/重写目录/重写插件/view(adminhtml | frontend)/templates/xxx/xxx.phtml

<?php
use Magento\Framework\App\Action\Action;
?>
<?php
// genki_catalog_isincart: layout.xml <block>注册的name
$isInCart = $block->getChildBlock('genki_catalog_isincart');

?>

<p>Qty: <?=$isInCart->getCartProductQty()?></p>

第二种：单独引入js

<?php
/**
 * @var $bolck \MxGenki\ChooseStore\Block\Adminhtml\Form\ApplyChange
 */

?>


<script>

require(['jquery'], function ($) {
    'use strict'
    $(function () {
        console.log("hello world");
    });
})
</script>
