我有一个网站，我使用PHP和MySQL数据库以及Apache服务器，并且我有一个记录页面，并且它有一个唯一的record_id号，每个记录都有一个唯一的record_id号，我从记录中进入我的画廊页面 页面，并且唯一的record_id编号转到图库页面并抛出URL，在图库页面中，我可以上传图片 到我的服务器上载图像（image_name）和缩略图（image_thumbnail_name）的文件夹，并且唯一的record_id号和标题以及record_date和filter_date以及image_name和thumbnail_name进入我的数据库，在record_images表中有七行，分别是image_id和record_id和record_date和filter_date以及标题和图像和缩略图。当我上传图像时，它通过使用PHP将图像的名称更改为rand号（image_name = rand（1000,9999）。“。”。fileExt;）一切正常，但我需要唯一的record_id号要添加在RAND编号的前面，因此图像的名称将类似于（record_id = 1_5826）和（record_id = 1_thumbnail_5826）或 像（record_id = 2_9631）和（record_id = 1_thumbnail_9631）这样，我就可以按图库页面中的record_id号过滤图像，这样您就只能看到该记录的图像，并且在需要的页面中有所有记录集他们输入ID号，然后我在Dreamweaver中建立了这个网站。
这是用于从记录页面转到图库页面的链接的代码，该页面具有唯一的record_id号，并且其中具有所有其他ID号以及用于向后导航的所有条件和属性。

这是在图库页面中将图像上传到服务器和数据库的功能，它从计算机上传图像，并在其中添加标题，ID号，标准和属性也随之添加。

这是image_upload_script文件的PHP代码，RAND函数是我试图将record_id号添加到RAND号前面的函数，它从secondary_upload_code.php文件中获取辅助代码都很好，但是添加了记录到RAND函数的record_id号。
