這篇文章主要介紹了淺談php提交form表單的2種方法和簡單的樣本，十分的實用，有需要的小夥伴可以參考下。
處理GET請求
實現的功能是輸入姓名後頁面顯示“Hello XXX”
建立html檔案hello.html：
?
| 1 2 3 4 5 6 7 8 9 10 11 12 13 | <!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> <title>歡迎</title> </head> <body> <form action="hello.php" method="get"> <input name="name" type="text"/> <input type="submit"/> </form> </body> </html> |
建立PHP檔案hello.php：
?
| 1 2 3 4 5 6 7 8 9 10 11 12 13 | <?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']){//如果有值且不為空白 echo 'Hello '.$_GET['name']; }else{ echo 'Please input name'; } |
Get請求把表單的資料顯式地放在URI中,並且對長度和資料值編碼有所限制，如：http://127.0.0.1/hello.php?name=Vito
處理POST請求
實現一個簡單的加法運算功能
建立html檔案add.html:
?
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | <!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> <title>相加</title> </head> <body> <form action="add.php" method="post"> <input name="num1" type="text"/> + <input name="num2" type="text"/> <input type="submit" value="相加"/> </form> </body> </html> |
建立PHP檔案add.php：
?
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 | <?php /** * Created by PhpStorm. * User: Administrator * Date: 2015/6/30 * Time: 18:02 */ if($_POST['num1']&&$_POST['num2']){ echo $_POST['num1']+$_POST['num2']; }else{ echo 'Please input num'; } |
Post請求把表單資料放在http請求體中,並且沒有長度限制
form action=""意思是：form是表單，action是轉向地址，即form表單需要提交到哪裡
