提交表單后，PHP重定向到另一個URL

Question

我有一個包含基本信息（姓名，姓氏，出生日期，電話，電子郵件）的網絡表單

提交表單並將這些字段的數據插入MySQL數據庫后，我希望能夠重定向到其他URL。 我嘗試使用php的標頭函數，但由於某種原因，它不會將我重定向到我指定的URL。

<?php
if ($_POST) {
            $host="23.229.187.201"; // Host name 
            $username="inturuser"; // Mysql username 
            $password="admin123"; // Mysql password 
            $db_name="intur"; // Database name 
            $tbl_name="test_mysql"; // Table name 

// Connect to server and select database.
            $link = mysql_connect("localhost", "inturuser", "hola123")or die("Error"); 
            mysql_select_db("intur")or die("cannot select DB");
// Get values from form the form 

            $name=$_POST['name'];
            $lastname=$_POST['lastname'];
            $email=$_POST['email'];
            $bday = date('Y-m-d', strtotime($_POST['bday']));
            $phone = $_POST['phone'];
            $datetime = date('Y-m-d H:i:s');
            $ip = ""; 
            if (!empty($_SERVER['HTTP_CLIENT_IP'])) {
    $ip = $_SERVER['HTTP_CLIENT_IP'];
} elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
    $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
    $ip = $_SERVER['REMOTE_ADDR'];
}


// Insert data into mysql 
$sql = 'INSERT INTO users (nombre, apellido, correo, fecha_nacimiento, telefono, ip_restaurante, timestamp) 
VALUES("'.$name.'", "'.$lastname.'", "'.$email.'", "'.$bday.'", "'.$phone.'", "'.$ip.'", "'.$datetime.'")';

mysql_query($sql);

mysql_close();

// if successfully insert data into database, displays message "Successful and redirect to a URL ". 
if($result)  

{
        header('Location: http://www.example.com/');;
}

else {
echo "ERROR";
     }

//close connection 

   } 

   else {
echo "NO POST"; 
   }
     ?>

Answer 1

您尚未分配$result變量，因此if($result)始終為false。

您應該打開error_reporting以顯示E_NOTICE，然后需要用$result = mysql_query($sql)替換mysql_query行。

Answer 2

您的代碼：

$sql = 'INSERT INTO users (nombre, apellido, correo, fecha_nacimiento, telefono, ip_restaurante, timestamp) 
    VALUES("'.$name.'", "'.$lastname.'", "'.$email.'", "'.$bday.'", "'.$phone.'", "'.$ip.'", "'.$datetime.'")';

    mysql_query($sql);

    mysql_close();

    // if successfully insert data into database, displays message "Successful and redirect to a URL ". 
    if($result)  

    {
            header('Location: http://www.example.com/');;
    }

請從標題中刪除多余的分號。 並分配$result=mysql_query($sql)

更正的解決方案：

 $sql = 'INSERT INTO users (nombre, apellido, correo, fecha_nacimiento, telefono, ip_restaurante, timestamp) 
    VALUES("'.$name.'", "'.$lastname.'", "'.$email.'", "'.$bday.'", "'.$phone.'", "'.$ip.'", "'.$datetime.'")';

    $result=mysql_query($sql);

    mysql_close();

    // if successfully insert data into database, displays message "Successful and redirect to a URL ". 
    if($result)  

    {
            header('Location: http://www.example.com/');
    }
