Why Facebook Like button load large js files? - javascript

To integrate Facebook Like button, I included a piece of js code according to Facebook Developer guide, but found it loaded several js files, and in total, it consumes 273kb which is even larger than my SPA js.
Could anyone explain this and advice on how to reduce it?
Thanks a lot!

Can't figure out how to make a registration script work

So I am a newbie, making a website for a school project.
I am trying to make a registration script work, but it doesn't work, and I can't figure out why. I have looked through the scripts, and I can't see anything that should be different :(.
Therefore I come looking for help to you guys :).
Thought that a pop-up window would be nice, so that's what I went for (coded in pure css first, then decided I wanted it to actually work.).
Everything is in the same directory.
I am using Xampp, so I access the main page with localhost/stronaszkolna/main.php
Here is a link to the entire website folder, that I uploaded to Google Drive, so it's easier for you to see: https://drive.google.com/drive/folders/1CXzzpLK-D0mYlIZI5sZDwRErj2FJnHfO?usp=sharing .
Tried putting the code in here too, but using snippet the main.php didn't load correctly.
When using "Code sample" parts of the code were being shown as normal text, so I just decided to upload the whole thing to google drive.
Here is how the table in my db looks like:
Sorry for not uploading it correctly. New to stackoverlow :D.
Thanks in advance!

Contact form with file uploader solution

I'm building a website (no CMS or framework) that needs a contact form with a file uploader. I've already written a PHP script for a standalone contact form, but I'm not sure how to go about connecting it with a file uploader that will store the files on the server and will also work on mobile devices.
Since I'm not very experienced in this topic, my questions are:
Would this be too difficult to manually write and implement?
Are there any existing solutions I can use?
Considering the website is almost done (structure/design have been built), should I switch to WordPress and use a plugin? I got 3/4 into converting the HTML into a theme, but I'd really prefer to continue this way
Any advice would be greatly appreciated. Thanks!
Uploading files without a framework is made quite easy with w3's guide:

Webbrowser not loading page content on Windows Phone 8

I'm building somewhat of a caching mechanism for some webpages, so that if the webpage is already stored in IsolatedStorage, then it's not necessary to fetch it online. However, when I'm loading the page, the content (CSS, js, images) arenĀ“t being loaded, although the files are already in the appropriate paths and the paths in the files all seem correct.
When I try using a very simple html with just an image in it, the content is loaded properly.
The more complex webpages have multiple sub-directories but all the paths to the content seem to be pointing correctly.
Any ideas on what may be happening? I've tried pretty much everything I've found on google, with no success. Is this just another buggy issue of the Webbrowser control on WP8 that I'm not aware of? I'd really appreciate if you have any suggestions.
Thank you in advance!
I managed to fix the problem. Apparently the main html file needs to be at the root of the folders' structure. Would be nice to have that information on the official msdn page. Hope at least this helps anyone that may have the same problem when loading local pages.
Thanks!

How to build GWT standalone offline application?

I need to design SPA with GWT technology, but I do not understand clearly how to make (compile) only one page with all JavaScript code in it.
So, for example my task is to make simple page with button and div. You click on button and div appears on page. Simple.
When I did this on GWT, I can not find a way to compile this page in simple index.html with all JS code inside (or in one .js file). Page should work in offline mode.
GWT do it for you. compile it to one .js file?
Here is simple tutorial http://code.google.com/intl/en/webtoolkit/doc/latest/tutorial/gettingstarted.html
If you have any other question, please ask
