浅谈php提交form表单，浅谈form表单
处理GET请求
实现的功能是输入姓名后页面显示“Hello XXX”
创建html文件hello.html：
<!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> <title>欢迎</title> </head> <body> <form action="hello.php" method="get"> <input name="name" type="text"/> <input type="submit"/> </form> </body> </html>
创建PHP文件hello.php：
<?php
/**
* Created by PhpStorm.
* User: Administrator
* Date: 2015/6/30
* Time: 15:03
*/
header("Content-type: text/html; charset=utf-8");
if(isset($_GET['name'])&&$_GET['name']){//如果有值且不为空
echo 'Hello '.$_GET['name'];
}else{
echo 'Please input name';
}
Get请求把表单的数据显式地放在URI中,并且对长度和数据值编码有所限制，如：http://127.0.0.1/hello.php?name=Vito
处理POST请求
实现一个简单的加法运算功能
创建html文件add.html:
<!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> <title>相加</title> </head> <body> <form action="add.php" method="post"> <input name="num1" type="text"/> + <input name="num2" type="text"/> <input type="submit" value="相加"/> </form> </body> </html>
创建PHP文件add.php：
<?php
/**
* Created by PhpStorm.
* User: Administrator
* Date: 2015/6/30
* Time: 18:02
*/
if($_POST['num1']&&$_POST['num2']){
echo $_POST['num1']+$_POST['num2'];
}else{
echo 'Please input num';
}
Post请求把表单数据放在http请求体中,并且没有长度限制
form action=""意思是：form是表单，action是转向地址，即form表单需要提交到哪里
