PHP提交表单为何一次提交两条记录
前端是一个form中有两个submit，通过js来实现点击两个button，一个提交到另一个页面，一个提交到自身。提交到另外一个页面实现插入数据库操作后再返回本页面显示。但是一次插入就会有两条记录。这怎么解决呢？
------解决思路----------------------
这个应该是你的JS提交了一次，然后submit这个又触发了一次，导致触发了2次
所以如果你要用JS来触发，那么你要先限制submit本身的触发
------解决思路----------------------
估计楼主的意思是这样的。
提交到后台，同时在本显进行展示
其实有两种方法
1，提交到后台，然后再跳转到当前页面（等于重新查询获取一次）
2，无刷新提交并展示，可以用Ajax
