Question

    <?php

    if($_SERVER["REQUEST_METHOD"]=="POST")
    {

        $connect = mysqli_connect("localhost","root","");
        mysqli_select_db($connect,"tegate");


        $subject = $_POST["subject"];
        $name = $_POST["name"];
        $size = $_POST["size"];
        $content = $_POST["content"];

        $query = "Insert into exampaper(subject, name, size) values ('$subject','$name','$size');";
        mysqli_query($connect, $query) or die (mysqli_error($connect));


        $sql = "INSERT INTO exampaper (content) VALUES (?)";

            $stmt = mysqli_prepare($connect,$sql);

            mysqli_stmt_bind_param($stmt,"s",$content);
            mysqli_stmt_execute($stmt);

            $check = mysqli_stmt_affected_rows($stmt);

            if($check == 1){
                echo "Image Uploaded Successfully";
            }else{
                echo "Error Uploading Image";
            }
        mysqli_close($connect);
    }

    ?>

我收到以下错误 - ：注意：未定义的索引：第13行的C：\ xampp \ htdocs \ TEGATE \ uploadpaper.php中的内容上传图片时出错我已经看到了所有相关问题，但我仍然无法找到错误。

$ content = $ _POST [“content”]; content字段的类型为mediumBlob，我想上传一个txt文件。我正在使用chrome的Postmaster应用程序检查php文件是否正常工作但是通过上面的行$ content = $ _POST [“content”];数据未与变量内容相关联。

注意：第13行的未定义索引
