用PHP批量添加数据到Mysql
首先接受过来的数据都在$_POST里，通过foreach我们来处理，我举个最简单的例子。
比如一些处理sql注入或js注入的函数叫check();
return 的是被处理后的结果，而非真或假。
下面是例子：
foreach($_POST as $key=$value){
$data[$key] = check($_POST[$key]);
$sql = "INSERT INTO test_table values('{$_POST[$key]}')";
mysql_query($sql);
}
html通过php把数据写入mysql
meta http-equiv="Content-Type" content="text/html; charset=utf-8"
form method="post" action="?do=ok"
ul
li用户名input name="yhm" type="text"/li
li电话input name="dh" type="text"/li
liinput name="提交" type="submit" value="提交"/li
/ul
/form
?php
if($_GET['do']=='ok'){
mysql_connect('localhost','数据库用户名','密码');
mysql_select_db('数据库名');
$result = mysql_query("INSERT INTO 表名 (用户名字段,电话字段) VALUES ('".$_POST['yhm']."','".$_POST['dh']."')");
if($result){
echo '插入成功';
}else{
echo '插入失败';
}
}
?
保存为php文件
php源码写入mysql数据库问题
$sql="insert into sfb_zhanghu(Account,Password) values ($zh,$mm)"; // 这出错
加单引号
values ( '$zh' , '$mm') // 数字可以不用放，字母一定要
php向mysql写入数据
if(!$sql)
{
echo('注册失败!');
}
else
{
echo('注册成功!');
}
这个判断明显是错误的，$sql 这肯定是有值的，它的值就是你给的sql语句。所以不管你怎么注册，都是输出注册成功。而应该判断它的反回值$query=mysql_query($sql,$con);如果注册不成功，$query=flase;否则反之.
php把数组写入mysql的方法
您好，您可以参考如下代码：
?php
/* 获取HTML表单提交的数据 */
$id = _POST["id"];
$catid = _POST["catid"];
$ly = array("data***");
/* 连接数据库，如果出错显示消息结束程序，否则继续执行数据库命令 */
$con = mysql_connect("127.0.0.1","user","password");
if($con == false)
{
echo "错误：系统数据库连接失败！错误信息：".mysql_error($con);
exit();
}else{
/* 选择需要操作数据库 */
mysql_select_db("mydb",$con);
/* 根据ly数组的长度决定执行多少次SQL语句 */
for($i=0;$icount($ly);$i++)
{
/* 设置SQL查询语句 */
$sql = "INSERT INTO `biaoge` VALUES('{$id}','{$catid}',".$ly[$i].")";
/* 如果SQL语句执行失败，返回错误代码； */
if(mysql_query($sql,$con) == false)
{
echo "数据库查询出错！错误代码：".mysql_errno($con);
mysql_close($con);
exit();
}
}
mysql_close($con);
echo "记录添加成功！";
}
?
至于遍历数组，有很多种方式，如楼上用的foreach语句也是可以的。这里用for的原因是为了方便提问者理解。如果代码仍有不足或不明白的地方，请您继续追问，直到给您一个满意的答复为止~
