1.构建思路
路由 noahbuscher/macaw
数据模型 catfan/medoo
视图 twig/twig
分页应用库 jasongrimes/paginator
文件图片上传 brandonsavage/Upload
图片水印 Intervention/image
单个文件自动加载helpers.php
2.构建框路由
composer require noahbuscher/macaw:dev-master
官方相关文件
https://github.com/noahbuscher/macaw
2.1在根目录下创建文件index.php，添加路由调用。如果还未设置自动路由需要手动composer dump-autoload
<?php
require('vendor/autoload.php');
use \NoahBuscher\Macaw\Macaw; //加载路由
Macaw::get('/', 'controllers\demo@index'); //案例
Macaw::get('page', 'controllers\demo@page');//案例
Macaw::get('view/(:num)', 'controllers\demo@view');//案例
Macaw::get('temp/lists', 'controllers\temp@lists');//案例
Macaw::dispatch();
3.自动加载控制器+单个文件加载
"autoload": {
"psr-4": {
"controllers\\": "app/controllers/", //自动加载控制器
"models\\": "app/models/"
},
//这种模式需要手动加载执行composer dump-autoload
"classmap": ["src/", "lib/", "Something.php"]
"files": ["app/helpers.php"] //单个文件加载
}
4.模板扩展加载 https://twig.symfony.com/doc/3.x/
composer require twig/twig:^2.12
4.1在控制器中创建Temp
<?php
namespace controllers;
class Temp
{
public function lists(){
$loader = new \Twig\Loader\FilesystemLoader('app/views');
$twig = new \Twig\Environment($loader, [
'cache' => '/path/to/compilation_cache',
]);
$navigation = array(array('href'=>'www.baidu.com','caption'=>'百度'),array('href'=>'www.baidu.com','caption'=>'百度'));
echo $twig->render('temp/lists.html', ['navigation' => $navigation]);
}
}
4.2在模板文件app/views中传教temp/lists.html文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<ul id="navigation">
{% for item in navigation %}
{{var_dump(item)}}
<li><a href="{{ item.href }}">{{ item.caption }}</a></li>
{% endfor %}
</ul>
<h1>My Webpage</h1>
{{ a_variable }}
</body>
</html>
4.3记得在index.php中添加路由
Macaw::get('temp/lists', 'controllers\temp@lists');
4.4效果图
4.5以上代码冗余过多，以下是优化为公共代码后，创建BaseController控制器，提炼出assign，display方法
<?php
namespace controllers;
class BaseController
{
protected $twig;
protected $data = array();
public function __construct()
{
$loader = new \Twig\Loader\FilesystemLoader(dirname(__DIR__).'/views');
$this->twig = new \Twig\Environment($loader,[]);
}
/**
* @param $var
* @param null $value
*/
public function assign($var,$value=null){
if (is_array($var)){
$this->data = array_merge($this->data,$var);
}else{
$this->data[$var] = $value;
}
}
/**
* @throws \Twig\Error\LoaderError
* @throws \Twig\Error\RuntimeError
* @throws \Twig\Error\SyntaxError
*/
public function display($template){
echo $this->twig->render($template.'.html', $this->data);
}
public function success($url,$mess){
echo "<script>";
echo "alert('{$mess}')";
echo "location.href='{$url}'";
echo "</script>";
}
public function error($url,$mess){
echo "<script>";
echo "alert('error:{$mess}')";
echo "location.href='{$url}'";
echo "</script>";
}
}
直接赋值
public function lists()
{
$model = new TempDao();
$navigation = $model->select('meiyou_admin', '*', ['nickname' => '测试']);
$this->assign('navigation',$navigation);
$this->display('temp/lists');
}
5.模型增加
官方文档https://github.com/catfan/Medoo
composer require catfan/medoo
案例，把temp中list方法的数据获取切换为以下代码，页面输出正常
//获取数据
$options = [
'type' => 'mysql',
'host' => '47.107.65.114',
'database' => 'meinian',
'username' => 'root',
'password' => 'gqa123'
];
$model = new Medoo($options);
$navigation = $model->select('meiyou_admin',
'*'
, [
'nickname' => '测试'
]);
5.2优化代码创建BaseDao继承Medoo,同时需要增加composer配置
"autoload": {
"psr-4": {
"controllers\\": "app/controllers/",
"models\\": "app/models/" /
},
"files": ["app/helpers.php"]
<?php
namespace models;
use Medoo\Medoo;
class BaseDao extends Medoo
{
function __construct()
{
$options = [
'type' => 'mysql',
'host' => '47.107.65.114',
'database' => 'meinian',
'username' => 'root',
'password' => 'gqa123'
];
parent::__construct($options);
}
}
<?php
namespace models;
class TempDao extends BaseDao
{
public function getList(){
$data = $this->select('meiyou_admin','*', ['nickname' => '测试']);
return $data;
}
}
6.分页模型
https://github.com/jasongrimes/php-paginator
composer require "jasongrimes/paginator:~1.0"
7.图片上传
https://github.com/brandonsavage/Upload
//图片上传
composer require "codeguy/upload"
//添加水印
composer require "Intervention/image"
``
在app文件夹下面传教uploader用于图片存储
案例代码如下在根目录下创建upload.html
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form method="POST" enctype="multipart/form-data" action="/temp/fileupload">
<input type="file" name="foo" value=""/>
<input type="submit" value="Upload File"/>
</form>
</body>
</html>
在temp控制器中添加方法
//注意 这个命名有重复需要用别名
use Intervention\Image\ImageManagerStatic as Image;
public function fileupload(){
$path = dirname(__DIR__).'\uploader';
$storage = new FileSystem($path);
$file = new File('foo', $storage);
// Optionally you can rename the file on upload
$new_filename = uniqid();
$file->setName($new_filename);
// Validate file upload
// MimeType List => http://www.iana.org/assignments/media-types/media-types.xhtml
$file->addValidations(array(
// Ensure file is of type "image/png"
new Mimetype(array('image/png', 'image/gif','image/jpg','image/jpeg')),
//You can also add multi mimetype validation
//new \Upload\Validation\Mimetype(array('image/png', 'image/gif'))
// Ensure file is no larger than 5M (use "B", "K", M", or "G")
new Size('50M')
));
// Access data about the file that has been uploaded
$data = array(
'name' => $file->getNameWithExtension(),
'extension' => $file->getExtension(),
'mime' => $file->getMimetype(),
'size' => $file->getSize(),
'md5' => $file->getMd5(),
'dimensions' => $file->getDimensions()
);
// Try to upload file
$file_name =$path.'/'.$new_filename.'.'.$data['extension'];
try {
// Success!
$file->upload();
//添加水印裁剪
// // open an image file
$img = Image::make($file_name);
// // resize image instance
$img->resize(320, 240);
// // insert a watermark
$img->insert($path.'/watermark.gif');
// // save image in desired format
$img->save($path.'/'.$new_filename.'_1.'.$data['extension']);
} catch (\Exception $e) {
// Fail!
$errors = $file->getErrors();
dd($errors);
}
}
总结：
此框架还有许多为完善的地方后续会进一步更新，这是一个长期的过程，文中相关源码地址
