首先直接做成一页,中间步骤的数据处理用JS,然后就可以正常提交,交给原系统的注册处理页面
怎么用php把html表单内容写入数据库
1:首先要使用PHP的超全局变量 $_GET 和 $_POST 用于收集表单数据(form-data)
2:然后使用INSERT INTO 语句用于向数据库表中插入新记录。
具体示例:
(1)首先创建了一个名为 "Persons" 的表,有三个列:"Firstname", "Lastname" 以及 "Age"。
?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("my_db", $con);
mysql_query("INSERT INTO Persons (FirstName, LastName, Age)
VALUES ('Peter', 'Griffin', '35')");
mysql_query("INSERT INTO Persons (FirstName, LastName, Age)
VALUES ('Glenn', 'Quagmire', '33')");
mysql_close($con);
?
(2)其次创建一个 HTML 表单,这个表单可把新记录插入 "Persons" 表。
html
body
form action="insert.php" method="post"
Firstname: input type="text" name="firstname" /
Lastname: input type="text" name="lastname" /
Age: input type="text" name="age" /
input type="submit" /
/form
/body
/html
(3)接着当用户点击上例中 HTML 表单中的提交按钮时,表单数据被发送到 "insert.php"。"insert.php" 文件连接数据库,并通过
$_POST 变量从表单取回值。然后,mysql_query() 函数执行 INSERT INTO 语句,一条新的记录会添加到数据库表中。
?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("my_db", $con);
$sql="INSERT INTO Persons (FirstName, LastName, Age)
VALUES
('$_POST[firstname]','$_POST[lastname]','$_POST[age]')";
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
echo "1 record added";
mysql_close($con)
?
php怎么从表单接收数据
PHP 可以通过POST、GET方法获取到表单提交的数据
获取到的POST、GET是数组形式的值,需要通过键值来详细获取相应的值
比如: index.php 页面
下面是POST方法
form name="form1" method="post" action="index.php"
input type="text" name="contents" value=""
input type="submit" value="提交"
/form
?php
//获取表单提交的数据
$contents = $_POST['contents'];
echo $contents;
?
也可以是下面是GET方法
form name="form1" method="get" action="index.php"
input type="text" name="contents" value=""
input type="submit" value="提交"
/form
?php
//获取表单提交的数据
$contents = $_GET['contents'];
echo $contents;
?
POST相对于GET方法,更好一些,可以提交大量数据,以及更安全些。
