PHP中怎樣把表單單選按鈕的值寫入數(shù)據(jù)庫中

p代碼中獲取表單中單選按鈕的值：（單選按鈕只能讓我們選擇一個，這里有一個“checked”屬性，這是用來默認選取的，我們每次刷新我們的頁面時就默認為這個值。）

例：form name="myform" action="" method="post"

性別:

input type="radio" name="sex" value="男" checked /鋒讓男input name="sex" type="radio" value="女" /女

input type="submit" name="submit" value="提交" /

/銀雹局form

?php

echo "您的選擇是：";

echo $_POST["sex"];

?

如果你選擇的是男，則出來的值就是“男”，要是你選擇的是女肆旁，則出來的值就是“女”。

如何通過PHP把html的表單提交到mysql數(shù)據(jù)庫？

首先，你得在diaocha.php這個文件，接收表單傳的值州橡

$radiogroup = isset($_POST['radiogroup'])?$radiogroup:'';

isset用來掘或檢測是否有選中提交，然后就是數(shù)據(jù)庫的鏈接

$con = mysql_connect('localhost','root',''); //三個參數(shù)，分別是，連接的主機名，mysql的賬號，mysql密碼

mysql_query('set names utf8'); //設置連接的字符集，如果頁面是utf8的編碼，就是utf8，如果是gbk的話，那就寫 set names gbk

mysql_select_db('xxx',$con);nbsp; //xxx就是你要選擇的數(shù)據(jù)庫名稱

插入數(shù)據(jù)

$sql = "insert into xxxx set xxx = $radiogroup" //xxxx 是你要插入的表名，xxx就判跡伍是字段名

mysql_query($sql);
