ThinkPHP完成对数据的添加以及表单数据的收集

数据添加分两种方式,一种是数组的方式,另一种是使用AR的方式添加,其实这两种方式添加的方式是相同的,就是一个规范的不同而已,所谓AR,就是:

//一个数据模型代表一张表。
//一个对象代表一条数据。
//一个字段代表一个对象的属性

这样也符合传统的思维习惯,下面是数据模拟添加的实例代码:

 

		$temp=D('User');
		// $arr=array('id'=>11,'name'=>'add_1_xuning','password'=>md5('123456'));
		//下面是通过AR的方式进行数据添加
		//一个数据模型代表一张表。
		//一个对象代表一条数据。
		//一个字段代表一个对象的属性
		$temp->name="add_xuning";
		$temp->password=md5('456');
		$res=$temp->add();
		// $res=$temp->add($arr);
		if($res){
			$info=$temp->select();
			$this->assign('info',$info);
			$this->display();
		}else{
			echo "添加失败";
		}
	}

然后就是收集表单数据进行添加:

 

1:{$smarty.const.__SELF__}表示当前问价的控制器路径。

2:收集数据添加有三种方法:

 

public function add_data(){
		if(!empty($_POST)){
			$arr=$_POST;
			$temp=D('User');
			//$res=$temp->add($arr);//直接添加
			// $temp->id=$_POST['id'];//AR添加
			// $temp->name=$_POST['usename'];
			// $temp->password=md5($_POST['password']);
			$temp->create();//create添加
			$res=$temp->add();
			if($res){
				echo "添加成功";
			}else{
				echo "添加失败";
			}
		}else{
			echo "内容为空";
			$this->display();
		}
	
	}
其中,如果对第数据有特殊的要求,可以使用第二种方式,高效安全的话就是用第三种方式,一般不建议使用第二种方式

 

 

这样的话,就完成了对数据的添加工作

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
