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

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
