我的单选按钮有问题，我可以编辑和插入，但它没有显示任何内容。我做错了什么？预先感谢您的帮助

单选按钮

<input type="radio" name="visible" value="0"<?php 
                if ($id['visible'] == 0) { echo " checked"; } 
                ?> /> {no}
                &nbsp;
                <input type="radio" name="visible" value="1"<?php 
                if ($id['visible'] == 1) { echo " checked"; } 
                ?> /> {yes}

ID

enter if(isset($_POST['id'])){
$id=$_POST['id'];
}else{
$id=$_GET['id'];
//echo $id;
} here



@$query  = "SELECT * FROM photographs WHERE id = '$id' ";
    //pokazuje co zostalo zmienione
    echo $query;

    $result = mysqli_query($connection, $query);
    if (!$result) {
        die("zapytanie sie nie powiodlo");
    }
    $row = mysqli_fetch_array($result);

?>

您的数组$row应该$id['visible']更改为$row['visible'].

<input type="radio" name="visible" value="0"<?php 
                if ($row['visible'] == 0) { echo " checked"; } 
                ?> /> {no}
                &nbsp;
<input type="radio" name="visible" value="1"<?php 
                if ($row['visible'] == 1) { echo " checked"; } 
                ?> /> {yes}

旁注：您的代码容易受到SQL Injection的攻击。考虑切换到Prepared Statement。
