Question

看来我的信息没有正确放入POST阵列。我是php的新手，所以我不太清楚为什么。我不知道你们都需要什么其他信息，所以我只是放置代码和错误信息。您可以提供的任何帮助/建议将不胜感激。

这是渲染后的表格。

这是我提交后的错误。

这是代码片段。我没有包括所有的HTML。我可能是因为我需要抛弃php并在java中编写内容。意见表示欢迎。

    REPLACE
    <form method="post" action="<?php echo htmlspecialcharachars($_SERVER["PHP_SELF"]);?>
    WITH
    <form method="post" action="<?php echo htmlspecialcharachars($_SERVER["PHP_SELF"]);?>">
