Question

我的图像问题应该像分页中的下一个按钮一样。在此页码上，next和previus按钮工作正常。

我希望能够点击图片＆＃34; Naprijed.png＆＃34;它应该将我重定向到＆＃34; smartphone?page=2＆＃34;。当页面为＆＃34; smartphone?page=2＆＃34;时，请点击图片＆＃34; Naprijed.png＆＃34;应该将我重定向到＆＃34; smartphone?page=3＆＃34;等

这是否可能以我想要的方式进行？

目前，在goForward功能中，您有以下代码：

window.location.href = "smartphone?page=$next";

这不起作用。您可以将$next放在PHP字符串中，但在PHP标记之外它只会被忽略。您可以通过将其放在PHP标记中来解决此问题：

window.location.href = "smartphone?page=<?php echo $next;?>";

编辑：此外，您在此代码之后定义了$ next变量。所以你需要提高它。

可以将图像链接为分页中的$ next吗？
