我是php的新手。我创建了多个表单。当我点击提交按钮显示＆＃34;提交成功＆＃34;。我创建了多个查询，以便将数据插入到不同的五个表中。
创建数据库连接时，我在...＆＃34;中出现了未定义的变量错误。我解决了这个问题后，我又出现了另一个错误＆＃34;未定义索引...＆＃34;。然后我修复了它，但再次显示＆＃34;未定义的变量...＆＃34;错误。
所以我使用以下代码来修复未定义的索引和未定义的变量错误。但是现在当我提交数据时表格没有很好地更新。正确填充了两个表。（contact_details表，extra_curricular_activity表）。一个表没有两个字段（academic_details表，Z_Score字段和A_Grade1字段）。其他两个表都是空的所有字段。但是在单击提交按钮时添加新行。（课程详细信息表，personal_details表）
数据库和错误字段的空字段是相同的......所以如何修复此
我使用以下代码修复未定义的变量和未定义的索引
