PHP - 删除按钮单击不起作用

Question

I need to make a delete button that only the admin can see. The button needs to delete an item in my database but I'm having troubles with the last part.

I used this code to create the button and to call the delete function when it's clicked

if ($_SESSION['UserID'] == 1) {
    echo '<button name="featureDelete"> Delete </button>' . '<br>';
    if (isset($_POST['featureDelete'])) {
        $deleteFeature = $feature->Delete($row);
    }
}

And this is my delete function in my class

public function Delete($row)
{
    $db = new db();
    $sql= "DELETE FROM features WHERE FeatureID ='".$row['FeatureID']."'";
    $db->conn->query($sql);
}

So I can see the button, but when I click it nothing happens, I even tried echo'ing something, but didn't get a result. What am I missing?

You have no form. Only a button.

echo '<form method="post"><button name="featureDelete"> Delete </button></form>' . '<br>';
