请帮助:(我已经被困了好几个小时了，这让我发疯了。

我建议你尝试一些调试。
例如，
$q = "INSERT INTO events (event_date, event_name, event_place) VALUES (?, ?, ?);
INSERT INTO event_pictures (event_id, image_name) VALUES ((SELECT event_id FROM events WHERE event_date = ?), ?);
";
$stmt = mysqli_prepare($dbc, $q) or die( mysqli_error($dbc) );
mysqli_stmt_bind_param($stmt, 'ssss', $event_date, $event_name, $event_place, $event_date, $i);
mysqli_stmt_execute($stmt) or die( mysqli_stmt_error($stmt) );
这将通知您可能的SQL错误。
此外，我认为你应该在这里使用mysqli_multi_query。
希望这有帮助。
和平！的xD

这可能是问题所在：
此处的ssss与您的变量数量不符。
mysqli_stmt_bind_param($stmt, 'ssss', $event_date, $event_name, $event_place, $event_date, $i);
这里有4个s，而你有5个变量。试试这个
mysqli_stmt_bind_param($stmt, 'sssss', $event_date, $event_name, $event_place, $event_date, $i);
