php - 使用php将数据输入mysql数据库

Question

客户将填写表格并输入他们希望将 CSV 导出到的路径。使用 php 的顶部部分输入路径(如下):

    <form action="register.php" method="post">
        Enter file pathway where CSV will be saved: <input type="text" name="username" required="required"/> <br/>
        <input type="submit" value="Enter"/>
    </form>
</body>

我想创建一个名为pathway的变量。目前，我可以将文本输入到 mysql 数据库中的正确行中(我可以在数据库中打印 John)，但不能将文本输入到表单中(即 $pathway)。我想创建一个变量，因为在数据库中保存路径后，我还想在 export.php 中使用它。

我假设我也需要这样的东西:

if($_SERVER["REQUEST_METHOD"] == "POST"){
    $pathway = mysql_real_escape_string($_POST['pathway']); 
// but i can't seem to piece it altogether.


    <?php
    $servername = "localhost";
    $username = "";
    $password = "";
    $dbname = "first_db";
    $table_users = $row['pathway'];
    $pathway = "pathway";                                             

    // Create connection
    $conn = mysqli_connect($servername, $username, $password, $dbname);
    // Check connection
    if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
    }

    $sql = "INSERT INTO users (pathway)
    VALUES ('John')";

    if (mysqli_query($conn, $sql)) {
    echo "New record created successfully";
    } else {
    echo "Error: " . $sql . "<br>" . mysqli_error($conn);
    }

    mysqli_close($conn);
    ?>

这应该有效，如果不行，请检查您的用户名和密码...

<?php
$servername = "localhost";
$username = "";
$password = "";
$dbname = "first_db";
$pathway = $_POST['username'];  username - is the name of your input.                                             

// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn)
{
    die("Connection failed: " . mysqli_connect_error());
}

$sql = "INSERT INTO users (pathway)
    VALUES ('$pathway')";

if (mysqli_query($conn, $sql)) {
    echo "New record created successfully";
}
else
{
echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}

mysqli_close($conn);
?>
