Question

下面提到的代码是 localhost / uploads / gallery.php 文件。我将它包含在另一个页面中，因此它可以成为页眉和页脚的一部分，包括我的所有样式。我是通过 include（'uploads / gallery.php'）; 进入div的。

除标题位置外，一切正常。当我进入包含图库的页面时，“localhost / index.php？page = media”（localhost / views / media.php）。它不显示缩略图。我必须刷新页面才能看到缩略图。注意：编写代码时会生成缩略图而不刷新页面。

我对提问的顾虑是，为什么我必须刷新页面才能加载缩略图。我的标头位置没有正确传递变量。我是一个完整的菜鸟。请帮我解决一下这个。 Shukriya。

图像库将变量传递到标题位置不起作用？
