yaopinbiao 这个表的表结构发出来看看,估计问题是与你这个表不止七个字段,而你却只给了七个值,其他没给值的字段又没有设定默认值或没允许为空之类的吧,

如果是数据库没连上肯定会提示 "连接数据库服务器失败。",程序肯定走不下去的了,估计是楼上说的,$number值重复了,因为你是用这个字段来当主键的,表里面主键值是必须为唯一的,重复值是插不进表里面的,你可以这样试试嘛,看看能不能插进去,
insert into yaopinbiao values($number, "$name", "$effect", "$danjia", "$scrq"."$yxq", "$sl");
// 或者这样 加个时间戳试试
insert into yaopinbiao values($number . time(), "$name", "$effect", "$danjia", "$scrq"."$yxq", "$sl");
// 或者是你这里有语法错误吧, $str = "insert into yaopinbiao values('$number','$name','$effect','$danjia','$scrq'.'$yxq','$sl')";
// '$scrq'.'$yxq' 改成 '{$scrq}{$yxq}'
// 试试吧

sql 语句错误
insert into 表名('对应的字段名1','xx2','xx3','xx4') values('$number','$name','$effect','$danjia','$scrq'.'$yxq','$sl')
insert into 表名('对应的字段名1','xx2','xx3','xx4') values('$number','$name','$effect','$danjia','$scrq'.'$yxq','$sl')

改过了但还是没有用呢,你看有可能是不是数据库没有连接上呢?
