ThinkPHP学习笔记(十二)ThinkPHP的分页以及验证码的使用

CommonAction

<?php /**
 * ThinkPHP中的
 * 让其他的Action继承当前的CommonAction就可以了
 */
class CommonAction extends Action{
	public function verify(){
		//导入验证码类
		//方式一:
		import('ORG.Util.Image');
		//方式二:@代表当前项目的lib文件夹(需要自己复制或者自己写一个新的类)
//		import('@.ORG.Image')
//		Image::buildImageVerify();
		
		//扩展修改 
		/**
		 * @param string $length  位数
		 * @param string $mode  类型(0字母,1数字,2大写字母,3小写字母,4中文,5混合)
		 * @param string $type 图像格式
		 * @param string $width  宽度
		 * @param string $height  高度
		 * buildImageVerify($length=4,$mode=1,$type='png',$width=48,$height=22,$verifyName='verify')
		 */
		Image::buildImageVerify(5,5,'png',80,22);
		//中文验证码(2.0会有一个问题:msubstr有错误)
		//1.修改function::msubstr
		//2.加入字体ttf需要放入image同级目录之下
		//扩展可以去类文件中查看
//		Image::GBVerify();
	}
}
?>


PageAction

<?php /**
 * ThinkPHP中的
 */
class PageAction extends CommonAction{
	public function index(){
		//导入page
		import('ORG.Util.Page');
		$user=M('User');
		$count=$user->count();
		$page=new Page($count, 3);
		//修改提示信息
		$page->setConfig('header', "个会员");
		$page->setConfig('prev', "上一组");
		$page->setConfig('next', "下一组");
		$page->setConfig('first', "首页");
		$page->setConfig('last', "尾页");
		
		//定义主题样式(去看文档)
//		$page->setConfig('theme', '<div>%%</div>');
		
		
		$show=$page->show();
		
		$list=$user->order('id desc')->limit($page->firstRow.','.$page->listRows)->select();
		
		$this->assign('title','page演示');
		$this->assign('alist',$list);
		$this->assign('page',$show);
		$this->display();
	}
	function check(){
		$verify=$_SESSION['verify'];
		if ($verify!=md5($_POST['verify'])) {
			$this->error("验证码错误");
		}
	}
	function next(){
	}
}
?>

    Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

    You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

    Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
