我尝试做的是查看task1，task2等打印任务的列，并添加yes / no单选按钮，但如果它为null则不打印单选按钮。这是一个开关盒吗？如何在最短的代码中完成整个超过200行。
目前，即使任务为空，也会为所有行添加选项（单选按钮）
这是代码。
$sql1 = "SELECT * FROM PMList where AssetNum= '$AssetNum';";
$result = mysqli_query($con, $sql1) or die(mysqli_error($con));
if ($result->num_rows > 0)
while($row = mysqli_fetch_array($result))
{

请帮忙。提前谢谢！

您可以在循环中检查任务是否为null，执行类似的操作：
if(!is_null($row['task1']) && $row['task1'] != "")
{
// here echo your radio button
}

用非常短的代码检查所有任务：
foreach(range(1,15) as $taskNumber){
if(is_null($row["task{$taskNumber}"]) OR empty($row["task{$taskNumber}"]))
echo "The task number: $taskNumber is null or empty<br>";
}
将此代码放入while循环中，现在您知道其中一个任务是空还是空。
