Php 如果提交了第一个表单，则页面上的第二个表单不会刷新目标页面
我有一个页面，从数据库中检索培训广告列表，并显示在表中。和另一个页面，当点击培训名称时，显示有关培训的详细信息。详细信息页面还允许编辑和删除广告。编辑或删除广告时，页面将重定向到广告列表。问题是，如果我编辑了一个广告，而没有访问另一个页面，如果我在重定向到广告列表页面时删除了该广告，则删除的广告仍在列表中。但是如果我没有编辑就删除了广告，或者在编辑后访问了另一个页面，然后返回并删除了广告，一切都正常。抱歉问了这么长的问题。感谢您的任何帮助。 代码如下 广告列表页：Php 如果提交了第一个表单，则页面上的第二个表单不会刷新目标页面,php,forms,Php,Forms,我有一个页面，从数据库中检索培训广告列表，并显示在表中。和另一个页面，当点击培训名称时，显示有关培训的详细信息。详细信息页面还允许编辑和删除广告。编辑或删除广告时，页面将重定向到广告列表。问题是，如果我编辑了一个广告，而没有访问另一个页面，如果我在重定向到广告列表页面时删除了该广告，则删除的广告仍在列表中。但是如果我没有编辑就删除了广告，或者在编辑后访问了另一个页面，然后返回并删除了广告，一切都正常。抱歉问了这么长的问题。感谢您的任何帮助。 代码如下 广告列表页： $connect = mysq

您应该检查表单操作url：

谢谢你的努力，但没有一个对我有用。当我更新信息并立即删除广告时，培训列表不会刷新您所说的刷新。您正在重定向该页面。如果不工作，则使用位置，并检查数据库您的查询是否工作正常是的，它将重定向到广告列表页面。查询也可以正常工作，因为在重定向到广告列表页面后，我访问了另一个页面并返回到广告列表页面，删除的广告不再出现在列表上尝试：header'Location:personal_ad_list.php'；还添加headerCache控件：无缓存；HeaderFragma：无缓存；名单上page@DincaAdrian也许您对解决方案有一个想法：
