我正在做一个项目，用户应该可以在表格中的HTML表格中填写数据，然后将其提交到数据库。
在表格中，表格如下所示:(第1张照片的上半部分）
但是，当我添加新行时，我没有下拉列表和无线电选项。对于Langauge名称，我想要一个可选的文本框字段，如果用户选择＆＃39;其他＆＃39;选项。 该表现在看起来像这样:(第1张照片的下半部分） HTML table before and after adding a row
我知道桌面的php代码是问题，但我不知道如何纠正它。
在数据库中，我只接收第一行的数据，但不接收后续的行。应该有2行具有相同时间戳的条目。 （第2张照片） Database entries of the HTML table
代码如下：
Page5.blade.php （javascript在blade.php文件中）
