Question

我不是专家开发人员，但我创建了一个发布我的新闻的编辑器。但每次我更新页面（使用f5或其他）我在我的数据库中发现了一篇新文章。所以我的数据库充满了一篇文章。有一个例子：https://image.prntscr.com/image/3z0d-9I5S9OUdGBCaytz2Q.png 这是我的代码，我错了吗？

 <?php

require_once('../db_conf.php');

$id = $key;

    $titolo = addslashes($_POST['titolo']);
    $immagine = addslashes($_POST['immagine']);
    $anteprima = addslashes($_POST['anteprima']);
    $testo = addslashes($_POST['testo']);
    $autore = addslashes($_POST['autore']);


mysql_query("INSERT INTO news (titolo,immagine,anteprima,testo,data,autore) VALUES ('".$titolo."','".$immagine."','".$anteprima."','".$testo."','".$date_full."','".$autore."')") or die(mysql_error());



?>

您需要提交按钮。如果单击该按钮，您的代码将会运行

<?php

    require_once('../db_conf.php');
    if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $id = $key;

        $titolo = addslashes($_POST['titolo']);
        $immagine = addslashes($_POST['immagine']);
        $anteprima = addslashes($_POST['anteprima']);
        $testo = addslashes($_POST['testo']);
        $autore = addslashes($_POST['autore']);


    mysql_query("INSERT INTO news (titolo,immagine,anteprima,testo,data,autore) VALUES ('".$titolo."','".$immagine."','".$anteprima."','".$testo."','".$date_full."','".$autore."')") or die(mysql_error());


    }
    ?>


            <main class="col-sm-9 ml-sm-auto col-md-10 pt-3" role="main">
            <center>  <h1>Inserisci News</h1></center>
