php - 无法使用 PHP 脚本更新 mysql 表

Question

我在php中有两个页面，

php_mysql_multiple_edit2.php //表单
php_mysql_multiple_edit.php //包含mysql更新命令的脚本

当测试期间数据库中的条目很少时，脚本运行得非常好并更新了表，但当我添加实际表时没有更新。

我收到以下错误

注意：未定义索引：第 6 行 /var/www/ELP/php_mysql_multiple_edit.php 中的 hdnLine 注意：未定义索引：第 25 行 /var/www/ELP/php_mysql_multiple_edit.php 中的 hdnLine 保存完成。

两者的代码是：

php_mysql_multiple_edit2.php

    <html>
    <head>
    <title>Employee Leave Portal</title>
    </head>
    <body>
    <p style="text-align: center">
        <a href="index.html">Home</a>
    </p>

$objQuery = mysql_query($strSQL) or die ("Error Query [".$strSQL."]");
?>

感谢大家的评论，aefxx 的建议对我帮助最大。我不得不更改 php.ini 中的设置以使其暂时运行，因为我将很快迁移到 PDO。

在 php.ini 中所做的更改：

将 post_max_size 增加到 20M
将 max_execution_time 增加到 -1
将 max_input_vars 增加到 2000
