You created a CSS class name .bgimg-1 , but you haven't used it anywhere. 您创建了一个CSS类名.bgimg-1 ，但尚未在任何地方使用它。 You likely want <body class="bgimg-1"> in order to assign that CSS to it. 您可能需要<body class="bgimg-1">以便为其分配CSS。
You should also make sure that file exists at the path specified. 您还应确保文件位于指定的路径。 You can find out in Chrome dev tools by inspecting the <body> and clicking the background URL to open it in a new tab. 您可以通过检查<body>并单击背景URL在新选项卡中将其打开，以在Chrome开发工具中查找。 Either an image will display, or you'll get a 404 error. 要么显示图像，要么会出现404错误。

Add the class you created to the body element. 将您创建的类添加到body元素。
<!DOCTYPE html> <?php session_start(); if(!isset($_SESSION["username"])){ header('location: ../index.php'); }else { ?> <html> <head> <title>GED</title> <link href="../paginaIniziale/css/bootstrap-4.0.0.css" rel="stylesheet"> <link rel="stylesheet" href="https://www.w3schools.com/w3css/4/w3.css"> <link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Lato"> <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css"> <style> .bgimg-1{ background-attachment: fixed; background-position: center; background-repeat: no-repeat; background-size: cover; background-image: url("https://i.stack.imgur.com/TYX0B.png"); min-height: 100%; } </style> </head> <body class="bgimg-1" bgcolor="blue" background="images/sfondo.png"> <div class="w3-top"> <div class="w3-bar w3-padding w3-card" style="background-color: #ffc107"> <h1>GED - SALC</h1> </div> </div> <div class="w3-display-middle w3-contener" > <a class="w3-center w3-padding-large w3-black w3-xlarge w3-wide" style="margin-left: 22px;">Seleziona un operazione</a> <div class="w3-center" style="margin-top: 40px;"> <a href="../pagineHtml/inserimento/inserimentoGenerale/inserimentoCantiere.php" class="w3-bar-item w3-button"><i class="fa fa-home"></i>Milano </a> <a href="azioniVisualizza/sceltaCantiere.php" class="w3-bar-item w3-button"><i class="fa fa-home"></i>Roma </a> </div> </div> </body> </html> <?php } ?>

You already set bgimg-1 class. 您已经设置了bgimg-1类。 All you need to add the class to the body tag. 您需要将类添加到body标签。 Also, you don't need to force it using background ="images/sfondo.png" in the body tag. 另外，您无需在body标签中使用background =“ images / sfondo.png”强制使用。
<body class="bgimg-1" bgcolor="blue">

First of all, the attributes "background" and "bgcolor" are old methods and are non-conforming, so you should use CSS background / background-color properties instead. 首先，属性“ background”和“ bgcolor”是旧方法，并且不符合要求，因此应改用CSS background / background-color属性。
Second, reading the comments it seems that your path is not correct. 其次，阅读注释似乎您的路径不正确。
Good luck! 祝好运！
