我的博客网站结构内的大家好,我有一个名为posts.php的页面,其中有一个表格可以让我添加新的帖子,除了图像不会显示在数据库中之外,其他所有内容都可以正常运行 但已上载到目标目录。如何在数据库中显示?这是用于处理add_post.php页面上的表单的代码/ * funtion的示例* /  函数add_post(){      全局$ connection;

 if (isset($_POST['submit'])) {

     $file = $_FILES['file'];

   $filename =$_FILES['file']['name'];
   $fileTmpName =$_FILES['file']['tmp_name'];
   $fileSize =$_FILES['file']['size'];


   $post_title =$_POST['post_title'];
   $post_content =$_POST['post_content'];
   $post_author =$_POST['post_author'];
   $post_category =$_POST['post_category'];
   $post_category_id =$_POST['post_category_id'];
   $post_status =$_POST['post_status'];


    $date = date("l d F Y");
    $post_views =0;
    $post_comment_count=0;

    $target_dir = "../images/";
    $target_file = $target_dir . basename($filename);
    $uploadOk = 1;
    $imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));

    if ( $fileSize > 1000000) {
        header("location:../posts.php?source=File is large");
        exit();
        $uploadOk = 0;
    }else {
        (move_uploaded_file($fileTmpName, $target_file));
    }

    $sql="INSERT INTO posts (post_title,post_content, post_image ,post_author,post_category,post_category_id,post_status,post_date, post_views,post_comment_count) 
    VALUES (?,?,?,?,?,?,?,?,?,?)";
     $stmt= $connection->prepare($sql);

     $stmt->bind_param("ssbssissii",$post_title, $post_content,$target_file ,$post_author, $post_category,$post_category_id,$post_status,$date,$post_views,$post_comment_count);
     if (!$stmt->execute()) {
         echo $connection->error;die;
     }else {
         header("Location:../posts.php?source=add_new");
     }

    }

}

将图像保存在服务器上的公共目录中,并且在数据库中仅保存已保存图像的目录。使用此目录,您将生成一个URL来访问文件。
