php表單提交代碼_如何用PHP實現表單提交

A. 由網頁提交的表單提交寫入資料庫 php源代碼該怎麼寫

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">
</form>
</body>
</html>

B. PHP怎麼把表單提交到本頁

PHP把表單提交到本頁,這個的話，我們是通過<form action="提交的文件名">來實現的，還有一個傳值的方式，post或者是get可以通過METHOD來實現的，這里我寫一段代碼：
<html>
<head></head>

<body>
<form action='文件名' method="post">
姓名<input type='text' value="">

密碼<input type='text' value="">
email<input type='text' value="">
</form>

</body>

</html>

C. PHP 表單提交數據到mysql

PHP 提交表單，然後保存資料庫示例：

1.sql腳本：

createdatabasecompany;
usecompany;
createtableemployee(
idint(11)notnullprimarykeyauto_increment,
emp_namevarchar(20)notnull,
emp_novarchar(30)notnull,
emp_jobvarchar(50)
);

2.index.php代碼：

<?php
header("Content-type:text/html;charset=utf-8;");
//判斷是否提交表單
if(isset($_POST['btn'])){
//連接資料庫
$conn=mysql_connect("localhost","root","root");
if(!$conn){
die("資料庫連接錯誤！".mysql_error());
}
mysql_select_db("company");
mysql_query("setnamesutf8");
//獲取表單提交元素
$emp_name=$_POST['emp_name'];
$emp_no=$_POST['emp_no'];
$emp_job=$_POST['emp_job'];
//驗證表單元素，然後入庫操作
if($emp_name&&$emp_no&&$emp_job){
$sql="insertintoemployee
(emp_name,emp_no,emp_job)
values
('{$emp_name}','{$emp_no}','{$emp_job}')
";
$int=mysql_query($sql);
$suc_msg="<fontcolor='green'>數據插入成功!</font><ahref='javascript:history.go(-1);'>返回</a>";
$err_msg="數據插入失敗";
exit($int?$suc_msg:$err_msg);
}else{
exit("提交數據全部為必填項！");
}
}
?>
<html>
<head>
<title>PHP表單提交示例</title>
<metahttp-equiv="content-type"content="text/html;charset=utf-8"/>
</head>
<body>
<formid="myform"action="<?phpecho$_SERVER['PHP_SELF']?>"method="post">
員工姓名：<inputname="emp_name"type="text"/><br/>
工號：<inputname="emp_no"type="text"/><br/>
工作職責：<inputname="emp_job"type="text"/><br/>
<inputname="btn"type="submit"value="提交表單"/><br/>
</form>
</body>
</html>

3.運行效果：

D. php表單提交到資料庫。請問如何寫r_save.php的代碼

<?php
$username = xxx; //資料庫用戶名
$password = xxx; //資料庫密碼
$con = mysql_connect("localhost",$username,$username);
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("my_db", $con);
mysql_query("INSERT INTO person (id, name, sex, phone, room_id, seat, date1, opinion)
VALUES ('$_POST[id]', '$_POST[name]', '$_POST[sex]', '$_POST[phone]', '$_POST[room_id]', '$_POST[seat]', ''$_POST[date1]', '$_POST[option]')");
mysql_close($con);
?>

E. PHP寫一個代碼怎麼做一個提交表單

樓上的Javascript方法可行，但如果用戶關閉Javascript支持就不起作用了。補充PHP代碼

<?php
if(!empty($_POST['str'])) {
header("Location: http://www.abc.com/qq/".$_POST['str']."/sina");
}
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<input type="text" size="16" name="str" value="" /> <input type="submit" value="Submit" />
</form>

F. 用php語言編寫提交表單的代碼急求求高手解答

加密的方法是md5()加密
密碼+常量方式
define(ALL_PS,"php");
例如echo md5('admin'.ALL_PS);
然後把列印出來的密碼串插入資料庫
資料庫和表的結構就自己創建吧，很簡單的

下面是方法是讀取資料庫中的密碼，然後開始登陸的密碼再加密和資料庫中讀取的比較，如果比較結果相同，則登錄成功
public function Get_user_login($username, $password) {
$username= str_replace(" ","", $_POST[username]);
$sql="select * from register where `username` = '$username'";
$query=$this->query($sql);

$us=is_array($row=$this->fetch_array($query));

$ps = $us ? md5($password.ALL_PS) == $row[password] : FALSE;
if($ps) {
$_SESSION[uid]=$row[uid];
$_SESSION[user_shell]=md5($row[username].$row[password].ALL_PS);
echo"<script>alert('登錄成功 ');location.href='admin.php'</script>";
}else{
echo"<script>alert('密碼或用戶名錯誤');location.href='admin_index.php'</script>";
session_destroy();
}
}

H. 如何用PHP實現表單提交

創建go.php,代碼如下

<?php

@$username = $_POST['name'];
@$usermessage = $_POST['message'];
if(!empty($username) || !empty($usermessage)){
echo "您的姓名：".$username.",您的留言內容：".$usermessage;
}else{
echo '<form action="go.php" method="post">
您的姓名：<input type="text" name="name"><br><br>
留言內容：<input type="text" name="message">
<button>提交</button>
</form>';

案例截圖：

I. PHP表單提交後出現的是自己的PHP代碼

像你表單應該是HTML的吧，提交給PHP做處理，像顯示代碼的話，好像APA沒處理啊？你應該在「瀏覽器」中打開表單，就應該可以了，還有，你可以加入，if語句，如果登陸成功，顯示登陸成功，否則，顯示失敗。我能答的就這么多了！答對的話，給分吧！！

J. php表單怎樣提交到當前頁面，並用$_POST獲取其值

<?php
$username=$_POST['username'];

?>

<form action="" ><input type="text" name="username"><input type="submit" name="submit" value="提交"></form>

form的action屬性留空的話就直接提交到當前頁面了後台直接$_POST獲取前台傳過來的表單域啊
