使 IPTC 数据可搜索
我对 IPTC 元数据有疑问。是否可以通过 IPTC 元数据(关键字)搜索不在数据库中的图像并显示它们,我将如何执行此操作?我只需要一个基本的想法。
我知道 PHP 有 iptcparse() 函数。
我已经编写了一个函数来获取画廊文件夹和所有子目录中所有图像的图像名称、位置和扩展名(扩展名为 .jpg)。
我需要弄清楚如何提取元数据而不将其存储在数据库中,以及如何搜索它,获取与搜索标签匹配的相关图像(它们的 IPTC 关键字应该匹配)以及如何显示它们。我知道此时我已经有了最终结果(搜索后),我可以使用 src="$filelocation"> 回显图像标签如果我有数组中的最终结果。
基本上,我不确定是否需要将所有图像存储到 mysql 数据库中,并提取关键字并将它们存储在数据库中,然后才能实际搜索和显示结果。另外,如果你能引导我到任何已经能够做到这一点的画廊,那也会有所帮助。
感谢您对这个问题的任何帮助。
I have a question about IPTC metadata. Is it possible to search images that aren't in a database by their IPTC metadata (keywords) and show them and how would I go about doing this? I just need a basic idea.
I know there is the iptcparse() function for PHP.
I have already written a function to grab the image name, location, and extension for all images within a galleries folder and all subdirectories by .jpg extension.
I need to figure out how to extract the metadata without storing it in a database and how to search through it, grab the relevant images that match the search tag (their IPTC keywords should match) and how to display them. I know at the point that I have the final results (post search) i can echo an imagetag with src="$filelocation"> if i have the final results in an array.
Basically, I am not sure if I need to store all my images into a mysql database and also extract the keywords and store them in the database as well before I can actually search and display the results. Also, if you could guide me to any gallery that already is able to do this, that could help as well.
Thanks for any help regarding this issue.

目前尚不清楚具体是什么给您带来了问题,但这也许会给您一些想法:
It is not clear what in particular is giving you problems, but perhaps this will give you some ideas:
如果您没有从图像中提取这些 IPTC 数据,则每次有人搜索时,您都必须:
如果您我想说,如果图像超过情侣,这对表演来说真的很糟糕。
因此,在我看来,最好是:
这意味着您现在需要做更多的工作:您有更多的代码要编写……
但这也意味着当有多个图像和许多用户进行搜索时,您的网站将有更好的生存机会。
If you don't have extracted those IPTC data from your images, each time someone will search, you'll have to :
If you have more than a couple image, this will be really bad for performances, I'd say.
So, in my opinion, it would be far better to :
It'll mean a bit more work for you right now : you have more code to write...
... But it also means your website will have better chances to survive when there are several images and many users doing searches.
