一、PHP實現添加mysql數據時,若是字段中含有中文,刷新時php不會報錯,數據不會添加到數據庫?php
緣由:Incorrect string value: '\xD6\xD0\xB9\xFA\xB1\xEA...' for column 'VARIABLE_VALUE' at row 1html
一、自增的話,能夠省略字段。mysql
二、 典型的字符編碼不一致問題jquery
解決:show variables like '%char%';show create table tbname; 查看字符集是否一致。ajax
重要在con鏈接數據庫設置:mysql_select_db("dch_db",$con);
mysql_query("set names gb2312");sql
請求PHP 頁:<meta http-equiv="Content-Type" content="text/html; charset=gdk" />數據庫
<?php
$con=mysql_connect("localhost","root","123456");
if(!$con){
echo "conection fail!".mysql_error();
}
mysql_select_db("dch_db",$con);
mysql_query("set names gb2312");
?>session
<?php
session_start();
include_once("conn.php");
//echo $_REQUEST[user];
?>post
二、要求對數據庫的用戶密碼加密?學習
解決:$pass = $_POST[pass];
//對密碼MD5加密
$pass = md5($pass);
$sql="select count(*) from tb_user where username='".$name."' and password='".$pass."' and display='管理員'";
//執行sql語句
$result=mysql_query($sql,$link);
數據字符長度設密碼長度爲32,
註冊:<?php
if ( $_POST["submit"] <> "" )
{
include("config.php");
$pass = isset($_POST['password']) ? $_POST['password'] : '';
echo $md5_password=md5($pass . ALL_PS);
$sql="insert into user_list (id,m_id,username,password)
values (null,'2','".$_POST["username"]."','".$md5_password."')";
mysql_query($sql);
}
?>
<p>sign up</p>
<form action="" method ="post">
user:<input type="text" name="username" /><br/><br />
passward:<input type="text" name="password" /><br /><br />
<input type="submit" name ="submit" value ="signup" />
</form>
