基本上我有2个简单的表...第一个叫做“user”,它是父表。 PK是索引自动递增。第二个表称为“useradvert”。 “id”字段充当不自动递增的索引键。每当我尝试插入数据时,它都不会进入表格(useradvert)。我的PHP页面上完全没有错误。我打开了错误报告。我设法创建一个没有错误的关系表。我试图解决这个问题好几天,并在网上搜索答案,但仍然无法找到并理解问题。问题是由于子表中的索引键(id)不是自动递增的吗?这两个id键是否应自动递增?
谢谢..真的需要你的帮助tqs ..
下面的表格定义为“users”-parent table和“useradvert”-child table;
useradvert

ALTER TABLE useradvert

这是用户页面(useracc-test.php),用户希望将数据插入表“useradvert”。页面显示以前注册的数据(来自表“user”,此页面还允许用户插入新数据(进入表“useradvert”)。

索引键不需要自动递增。相反,您应该将记录插入users
表,抓取该记录的id
,然后在id
表上手动插入useradvert
。
我怀疑你的错误是外键约束失败。如果在运行每个插入后检查错误,您可能会看到它。您提供id
的{{1}}必须首先在useradvert
表格中以id
的形式存在。

问题解决了..我忘了if(isset($ _ POST ['submit'])).. LoL.I做了一些小改动只是为了添加上面的isset ..现在一切正常..
