Question

我仍然是PHP / MYSQL的初学者，我在将数据插入MYSQL数据库时遇到了困难。（我最初尝试使用我的localhost数据库但是一旦我转移到在线服务器，一切似乎都停止了。）

现在，只要我从index.php页面提交数据，它就会刷新页面，不会添加任何数据。

但是，当我去submit.php时，一切正常，它会在我的results.php中添加一组空数据。

我的代码如下。任何帮助将不胜感激。谢谢！

的index.php

<html>
<head>
<title>POST variables</title>

<link rel="stylesheet" type="text/css" href="css/style.css" media="all">

</head>
<body>

<?php

$con = mysqli_connect('localhost', 'anas12_test', 'a1b2c3d4', 'anas12_test');

if (!$con) {
die('Connect Error (' . mysqli_connect_errno() . ') '
        . mysqli_connect_error());
}

    echo '<div class="container">

            <form id="profiles">
            <div class="header">

            <h3>Hello there!</h3>
            <p>We want to know more about you! Share a few interesting details about yourself using the form below!</p>

            </div>

            <div class="sep"></div>

            <div class="inputs">

            <form action="submit.php" method="post">

            <input id="name" name="name" placeholder="Full Name" required="" autofocus="" autocomplete="on" type="text">

            <input id="email" name="email" placeholder="Email Address" required="" autofocus="" autocomplete="on" type="text">

            <input id="superpower" name="superpower" placeholder="If you had a superhero ability, what would it be?" required="" autofocus="" autocomplete="on" type="text">  

    <button id="submit" type="submit"name="submit" value="added">Submit!</button>


            </form> </div>

            </div>'; 
?>

</body>
</html>

Submit.php

$con = mysqli_connect('localhost', 'anas12_test', 'a1b2c3d4', 'anas12_test');


if(isset($_POST["name"])){
    $name = $_POST["name"];
} else {
    $name = "";
}

if(isset($_POST["email"])){
    $email = $_POST["email"];
} else {
    $email = "";
}

if(isset($_POST["colour"])){
    $colour = $_POST["colour"];
} else {
    $colour = "";
}

if(isset($_POST["music"])){
    $music = $_POST["music"];
} else {
    $music = "";
}

if(isset($_POST["superpower"])){
    $superpower = $_POST["superpower"];
} else {
    $superpower = "";
}

$sql = "INSERT INTO profiles (name, email, colour, music, superpower) VALUES ('$name', '$email', '$colour', '$music', '$superpower')";
if(mysqli_query($con, $sql)){
header ('location: results.php'.$query_string);
} else{
echo "ERROR: Could not able to execute $sql. " . mysqli_error($con);
}

if($name !== "" && $email !== "" && $colour !== "" && $music !== "" && $superpower !== "") {

    $query_string = '?name=' . $name.'&email='.$email.'&colour='.$colour.'&music='.$music.'&superpower='.$superpower;
    header('HTTP/1.1 303 See Other');
    header ('location: results.php'.$query_string);     

} 

?>

Answer 1

您的表单没有action，因此它会将表单提交到您加载页面的网址，该网址为index.php。

你需要这个：

        <form id="profiles" action="Submit.php" method="POST">
                            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

同样注意method部分 - 没有方法，表格默认使用GET

Answer 2

小心你的index.php中有两个表单。

<form id="profiles">

和

<form action="submit.php" method="post">

我认为第一个没用。
