我是一个相当新手的网站管理员，正在努力为我的用户设置分类广告。（我基本上是在重建一个写得不好的分类广告）
我买了一个便宜的分类广告程序，所以我有一些东西可以学习 PHP，我已经走了很长一段路，但我距离理解如何将所有内容与现有的图像上传功能联系在一起还有很长的路要走，如果任何人都不会介意帮助我，我将不胜感激。
请允许我解释一下；
在这个分类广告的早期，访问者必须添加他们的列表（这是一个婊子）然后访问者必须去寻找他们可以上传他们的图像的地方。不用说，这不是削减它。
快进到现在；现在我在一个页面上有一个带有多个文本输入（即文本、选择、文本区域和一个复选框）的表单，并且在这个表单上我有 4 个图像上传按钮，如下所示。
<form id="generalform" class="container" method="POST" action="addlistingprocess.php" autocomplete="on" enctype="multipart/form-data" >

现在这是踢球者，（很抱歉创建这么长的帖子）
这个分类已经有一个现有的图像上传功能，我想保留它，因为它可以处理调整大小和显示图像，例如可以在这里看到： http ://classifieds.your-adrenaline-fix.com/detail.php?fatherID =10&TypeID=42&ListingID=7
我想将此功能与上面的表格联系起来，但是，该程序需要很多参数，我已经尝试了数周来理解这些参数，但仍然没有。（但是我已经从代码中清除了 sh^$ 以便理解它）
我将使用所有适用的文件作为代码关闭此线程，如果有人可以帮助我，我将不胜感激，我提前感谢大家。
这是images.php。（这是访问者在创建广告后必须导航到的地方，但它也是访问者可以添加或删除与其列表相关的照片的地方，所以我需要保留这个）
