点击后分页不显示结果

Question

这是一个简单的分页尝试。以为我会按照我所知道的去做。现在页面运行良好，我可以滚动浏览LIMIT $startfrom、$displayto(amount)

问题是第一页显示图像，但是一旦我单击按钮浏览图像，我就没有图像？但是当我点击返回时，我会这样做，但只有 3 个。

我真的不确定发生了什么，但分页结果应该是这样（0-5 , 5-5, 10,5 15,5 20,5) 等。但是在 0,5 之后 - 没有更多图像了。

我也通过FORM 发布$variables。

另外，当我浏览 DEV 时，我发现动态图像在第一页之后不存在。但是 LIMIT 是正确的，应该会按预期显示，只是由于某些奇怪的原因没有图像。我认为它与手动调用 MYSQ 以再次运行数据库有关，但我不确定为什么它不会通过 FORM POST 执行此操作，因为它会调用整个脚本和页面。

事实上，想想看，我最好只做一个图像滚动而不是分页。我会调查一下。但我绝对想知道如何完成分页。但是，如果有人可以提供简单的图像旋转，我会非常满意。

Answer 1

经过多次反复试验，我最终设法完成了我打算做的事情。代码最初不起作用的主要原因是因为搜索变量是从最后一个数据库 $data 更新为最后一个视频/图像/价格/定位/信息/等。所以变量发送到最后一个图像/视频的表单，而不是搜索字段....我修改了这个以删除被发布到表单的变量，并初始化 !isset & !empty 以在查询之前设置变量并且在 POST 之后，因此使用搜索查询数据而不是图像/视频数据来更新变量。所以最后在对代码进行了一些调整之后，我已经启动并运行了......

感谢您的关注。我希望这个简单的分页能在 1 天后对其他人有所帮助。

这是最终代码..
