我已经创建了一个用于标记12行的表/标题，但是如果用户填写或使用的内容少于给定的内容，该怎么办？ 那么我需要对我的php代码进行哪些更改以允许它，因为我的代码要求用户输入所有12行？
这是PHP代码：
<?php
mysql_connect("localhost", "root", "") or die(mysql_error());
mysql_select_db("abc") or die(mysql_error());
$tablename = $_POST['title'];
$cat1 = $_POST['title_1'];
$cat2 = $_POST['title_2'];
$cat3 = $_POST['title_3'];
$cat4 = $_POST['title_4'];
$cat5 = $_POST['title_5'];
$cat6 = $_POST['title_6'];
$cat7 = $_POST['title_7'];
$cat8 = $_POST['title_8'];
$cat9 = $_POST['title_9'];
$cat10 = $_POST['title_10'];
$cat11 = $_POST['title_11'];
$cat12 = $_POST['title_12'];
$mark1 = $_POST['title_1_1'];
$mark2 = $_POST['title_1_2'];
$mark3 = $_POST['title_1_3'];
$mark4 = $_POST['title_1_4'];
$mark5 = $_POST['title_1_5'];
$mark6 = $_POST['title_1_6'];
$mark7 = $_POST['title_1_7'];
$mark8 = $_POST['title_1_8'];
$mark9 = $_POST['title_1_9'];
$mark10 = $_POST['title_1_10'];
$mark11 = $_POST['title_1_11'];
$mark12 = $_POST['title_1_12'];
mysql_query("CREATE TABLE $tablename (
id INT(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,
$cat1 INT($mark1), $cat2 INT($mark2), $cat3 INT($mark3), $cat4 INT($mark4), $cat5 INT($mark5), $cat6 INT($mark6),
$cat7 INT($mark7), $cat8 INT($mark8), $cat9 INT($mark9), $cat10 INT($mark10), $cat11 INT($mark11), $cat12 INT($mark12),
Total INT (200))")
or die(mysql_error());
header("Location: index2.php");
?>
这是界面：
