我已经使用此代码3天了，但仍然看不到为什么它不想运行。但是我很确定这是一个非常简单的错误。

if(isset($_POST['submit'])){    
    $title = $conn->real_escape_string($_POST['title']);
    $author_id = $conn->real_escape_string(trim($_POST['authors']));
    $content = $conn->real_escape_string(trim($_POST['content']));
    $content_folder = date("Y");
    $image = $conn->real_escape_string($_POST['image']);
    $main_page = $conn->real_escape_string(trim($_POST['main_page']));
    $category = $conn->real_escape_string($_POST['categories']);
    $published = $conn->real_escape_string(trim($_POST['published']));
    $keywords = $conn->real_escape_string(trim($_POST['keywords']));
    $description = $conn->real_escape_string(trim($_POST['description']));


    // Insert into DB
    $insert_row = $conn->query("INSERT INTO articles (title, author_id, content, content_folder, main_image, main_page, category, published, keywords, descinfo) 
    VALUES($title, $author_id, $content, $content_folder, $image, $main_page, $category, $published, $keywords, $description)") or die(mysqli_error($conn));

    if($insert_row){
        header('Location: '.$url.'/a/index.php?page=add&msg=ok');
    }else{
        echo '<div clas="error">Something went wrong</div>';
        die(mysqli_error($conn));
    }
}

它给了我语法错误1064。不胜感激。

最佳答案

您缺少单引号：

$insert_row = $conn->query("INSERT INTO articles (title, author_id, content, content_folder, main_image, main_page, category, published, keywords, descinfo) 
VALUES('$title', '$author_id', '$content', '$content_folder', '$image', '$main_page', '$category', '$published', '$keywords', '$description')");
