Question

我是PHP的新手。我必须更新特定ID的数据。我正在使用准备好的语句进行更新。但是出现很多错误...任何人都可以帮助我解决这个错误。

我尝试了正常的更新查询。它工作正常。但是当我使用准备好的语句时。我遇到了错误。

<?php
    if (isset($_POST['submit'])) {
        // Assigning to variables
        // Assigning to variables
        $domain = $_POST['domain'];
        $project_name = $_POST['project_name'];
        $contact_number = $_POST['contact_number'];
        $contact_person = $_POST['contact_person'];
        $domain_setup = $_POST['domain_setup'];
        $hosting_setup = $_POST['hosting_setup'];
        $expiry_date = $_POST['expiry_date'];
        $period = $_POST['period'];
        $cpanel_name = $_POST['cpanel_name'];
        $cpanel_password = $_POST['cpanel_password'];
        $wp_username = $_POST['wp_username'];
        $wp_password = $_POST['wp_password'];
        $domain_mails = $_POST['domain_mails'];
        $domain_host = $_POST['domain_host'];
        $domain_username = $_POST['domain_username'];
        $domain_password = $_POST['domain_password'];
        $place = $_POST['place'];
        $extra_notes = $_POST['extra_notes'];
        // mysqli_connect() function opens a new connection to the MySQL server.
        $conn = mysqli_connect("localhost", "root", "", "mydomain");
        // SQL query to insert information of register table.
        // prepare and bind
        $sql = $conn->prepare("UPDATE domin_register 
                    SET domain= ?, project_name= ?, contact_number= ?, 
                        contact_person= ?, domain_setup= ?, hosting_setup= ?, 
                        expiry_date= ?, period= ?, cpanel_name= ?,
                        cpanel_password= ?, wp_username= ?, wp_password= ?, 
                        domain_mails= ?, domain_host= ?, domain_username= ?, 
                        domain_password= ?, place= ?, extra_notes=?  
                    WHERE domain_id = ?");
        $stmt = mysqli_stmt_init($conn);
        mysqli_stmt_bind_param($stmt,'ssssssssssssssssss', 
                $domain, $project_name, $contact_number, 
                $contact_person, $domain_setup, $hosting_setup, 
                $expiry_date, $period, $cpanel_name, $cpanel_password, 
                $wp_username, $wp_password, $domain_mails, $domain_host, 
                $domain_username, $domain_password, $place, $extra_notes);
        mysqli_stmt_execute($stmt);
        $stmt->execute();
        $stmt->close();
    }
?>

我想用错误更新数据

我的错误如下：

警告：mysqli_stmt_bind_param（）：第213行的D：\ Xampp \ htdocs \ mydomain \ updatedata.php中的无效对象或资源mysqli_stmt

警告：mysqli_stmt_execute（）：无效的对象或资源mysqli_stmt位于214行的D：\ Xampp \ htdocs \ mydomain \ updatedata.php中

警告：mysqli_stmt :: execute（）：第215行的D：\ Xampp \ htdocs \ mydomain \ updatedata.php中无效的对象或资源mysqli_stmt

警告：mysqli_stmt :: close（）：第216行的D：\ Xampp \ htdocs \ mydomain \ updatedata.php中的无效对象或资源mysqli_stmt

使用准备好的语句无法更新行，更新时出错
