Using Chrome you can right click - Inspect element to see the html code behind that element: I wonder how to find which php file has generated that html. If yes you have found the template, look at what you have follow the includes/ requires to appropiate files, you'll find your html somewhere either as html or php code creating html.
Maybe there is some tool to put a breakpoint into the html so the php server will stop when trying to generate it again? This might be a good point to mention if you ever create a entire plugin, store files logically and include from a file controller or plugin file. Actually it would be nice a Word Press plugin to add that code at the beginning of every php file.
Hard to really tell without seeing the site, but have you looked at some file uploading/downloading plugins for WP? See if any of them fit your needs, at least should be better than using WP's default media loader which isn't designed for that kind of thing.
Open the post editor and click on the Add Media button. I would suggest to either link it to a text or an image.
If you think you have found the correct template, try a echo to see if it appears on screen.
Store pages in a pages folder so they are easy to find. update: filter to output path on template files hmm you could open every file and write it in with php i suppose, or do it manually, but honestly what i do is the above, i will find template files fairly quickly and then follow require/includes. Should I create a new public with that exact piece of code inside. Not a task for me (yet, as I'm starting with Word Press).
For instance, there are PSD mockups, files, files, and the occasional package that they would need to share. I thought this would be as uploading the media, setting a thumbnail, and then directing the user to right click and save target as.
This seems to work with some file types (easy ones... For example, the files I have uploaded are showing up just fine within the posts, but when downloaded, it will appear to download a file that has zero data, and when you attempt to open the file it will show up as null.
Many companies claim that they host Word Press are scammers, they offer free services just to force people to upgrade their accounts later.
