下面是页面上的所有PHP脚本。该页面可以创建奇迹，直到我的一个用户遇到问题。他们给我发了消息，并说编辑功能不再起作用。通常，当您点击“更新”时您将看到一条消息，表明您的愿望清单已更新，但对于此用户，当他们点击更新按钮时，它只是刷新了页面。它不再更改数据库中的信息。
我尝试从数据库中删除一些条目，然后用户就可以编辑了。一旦他们将这些生物添加回来，但它不再起作用，事实上它在另一个地方爆发了。
第一次愿望清单更新功能突破了162个生物，而这次它突破了168个生物。
什么可能导致这种奇怪的故障？我该怎么办才能修复它？谢谢你！

答案 0 :(得分：0)
问题是我的服务器无法处理页面上的表单条目数。我设置了分页，从那时起一切都很好！
