由網(wǎng)頁提交的表單提交寫入數(shù)據(jù)庫 PHP源代碼該怎么寫

把下面的代碼保存為post.php

?

$conn = mysql_connect("localhost","11111","22222");

$action = $_POST['action'];

if($action == 'send'){

$username = $_POST['username'];

$password = $_POST['password'];

mysql_select_db("333333",$conn);

$sql = "INSERT INTO player (username,password) VALUES ('$username','$password')";

$result = mysql_query($sql,$conn);

}

?

html

body

form method="post" action="post.php"

input type="text" name="username"

input type="text" name="password"

input type="hidden" name="action" value="send"

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

php源碼寫入mysql數(shù)據(jù)庫問題

$sql="insert into sfb_zhanghu(Account,Password) values ($zh,$mm)"; // 這出錯

加單引號

values ( '$zh' , '$mm') // 數(shù)字可以不用放，字母一定要

怎么把php源碼數(shù)據(jù)庫導(dǎo)入數(shù)據(jù)庫

可以參考：

一般是單獨(dú)導(dǎo)入的，

在mysql上，要用mysql_import工具 把文本導(dǎo)入

sqlserver上可以用數(shù)據(jù)庫備份工具恢復(fù)導(dǎo)入， 也可以使用其他數(shù)據(jù)庫引擎通過ado到。

不需要源碼，但是需要了解php源碼所需要的庫表結(jié)構(gòu)。一般php源碼里好多都有建立空庫結(jié)構(gòu)的源碼。
