Question

我是php的初学者，我刚刚在php中创建了base64编码器和解码器。它工作正常，但我想要用户尝试存储在数据库中的所有哈希值。它没有显示任何语法错误，我可以发现任何奇怪的东西。请帮帮我。一切都在一个名为的文件中的的index.php

 <?php

$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = '';
$db = 'base64';

$dbconn = mysql_connect($dbhost, $dbuser, $dbpass);
mysql_select_db($db);
?>

    <div class="spinner"></div>
    <div class="template">
    <h1>Base 64 Encoder</h1>
    <form method="POST" action="#">
        <input type="text" name="encode">
        <input type="submit" name="encodebtn">
    </form>

    $text = $_POST['decode'];
    $decodehash = base64_decode($text); 
    $encodehash = base64_encode($text);

    $query = ("INSERT INTO hashes (Encoded, Decoded) VALUES ('$encodehash', '$decodehash')");
}
if (isset($_POST['encodebtn'])) {
    $text = $_POST['encode'];
    $encodehash = base64_encode($text);
    $decodehash = base64_decode($text);

Answer 1

你忘记了

HttpContext

在$ query变量之后键入它;

用此代码替换您的代码

    <?php

$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = '';
$db = 'base64';

$dbconn = new mysqli($dbhost,$dbuser,$dbpass,$db);

?>

            $query = ("INSERT INTO hashes (Encoded, Decoded) VALUES ('$encodehash','$decodehash')");
            $dbconn->query($query);
        }
        if (isset($_POST['encodebtn'])) {
