1.form表单默认情况下提交数据的方式为get方式。
2.PHP脚本用来处理表单数据的预定义变量是$_GET,$_POST(区分大小写)
代码示例:(特别注意复选框属性name的时候加数组)
simpleTest.html
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Insert title here</title> </head> <body> <form action="simpleForm.php" method="post"> 用户名:<input type="text" name="username"><br> 密码:<input type="text" name="password"><br> <!-- 复选框 --> 学过的编程语言是:<br> <input type="checkbox" name="language[]" value="PHP">php <input type="checkbox" name="language[]" value="java">java <input type="checkbox" name="language[]" value="C#">C# <input type="checkbox" name="language[]" value="C++">C++<br> <input type="submit" value="提交" > </form> </body> </html>
simpleFoem.php
<?php if(!empty($_POST["username"])){ if($_POST["username"]=="zhangsan"&&$_POST["password"]=="123"){ echo "欢迎您:".$_POST["username"]."<br/>"; echo "学过的编程语言:"; foreach ($_POST["language"] as $value){ echo $value; } }else { echo "用户名密码错误"; } } ?>
