Do I have a way to retrieve post data submitted via HTML form? Particularily in Firefox, on Windows XP. I suppose Firefox holds it in it's directory inside Application Data, but they are bunch of files which names do not give any clue. They don't even have extensions, some of them are text, some binary.
Just don't tell me that post data is not stored anywhere locally.
Of course it isn't stored locally.
Do you really want Firefox to store all of your passwords and credit card numbers?
Submitted form data is not stored locally or remotely unless you have software built to do something with it. With some of the new HTML5 additions (local storage) you could code up something in JavaScript to store your posted form data but this would only be on your computer. Generally you want to post data to a remote server for processing and/or storage using one of the many server-side programming languages.
Hope this helps and sorry to give you the answer you didn't want to hear. :-)

I'm learning to code and encounter a problem with making a form using HTML.
In the book, it stated that "every <form> element requires an action attribute and its value is the URL for the page on the server that will receive the information in the form when it is submitted."
But I thought about it for a long time, and I couldn't figure it out. What is meant by "the URL for the page on the server". If I got a site uploaded to a web hosting company, I would need to get it there? Or I need to rent a server elsewhere so that I will get one? Or it just fine to be store on a local file? Because I saw the data need to be processed by PHP, although I don't know whats that.
Can anyone help me with this? Really appreciated.

An HTTP(S) URL will include a hostname (which identifies a computer (acting as a server) on a network) and a path (and possibly some other components which don't matter for this question).
When you type a URL into the address bar of a browser, the browser will make a request to the server and ask for whatever is at the path.
The server will respond (typically with some data like an HTML document).
The server has to perform some logic to decide what to respond with. Typically this will either be:
Reading a file from its hard disk and returning the contents or
Executing a program and generating some content programmatically
When you submit a form, you are making a request to a URL with some data attached to it. Almost all of the time you will want the server to execute a program and do something with that data (such as put it in a database).
The program that gets executed can be written in any programming language you like (such as Perl, PHP, JavaScript, Java, or whatever).
If I got a site uploaded to a web hosting company, I would need to get it there?
Typically, if you have web hosting already then you will use that web hosting for any server-side programming you need to do.
If the hosting service doesn't provide you with any server-side hosting options (i.e. if it is just static hosting such as you might find from Github Pages). Then that isn't an option. Likewise if the server-side options they program aren't suitable for you (e.g. they only support PHP but you want to run something written in Node.js) then you'll have to find an alternative.
The two alternatives you have are:
Move everything to hosting that provides the features you want
Host something elsewhere and keep the majority of your site in the original hosting
(There is nothing wrong with the latter option, I have one site which uses Amazon S3 static hosting for most of it but has a couple of web services running in Heroku).
Or I need to rent a server elsewhere so that I will get one?
Dedicated hosting is almost certainly very expensive overkill for your purposes.
Or it just fine to be store on a local file?
It isn't possible to do server-side programming with a file: scheme URL. There's no server to execute the program.
If you are only working locally then you can install a web server on your computer. This is normal for development purposes.
It is probably worth mentioning that there are a few common server-side programs which are available prewritten with hosting services (e.g. contact forms which email you when someone fills them in). These typically come with advertising and require that the <form> and its contents are constructed with the specific fields the service expects. If you look for one of these be careful to follow their instructions precisely.
Aside: The statement that the action attribute is required is flat out wrong. It is an optional attribute and in its absence the form will be submitted to the URL of the current page.
HTML is a front-end tool that allows you to take inputs using a form from the user. once the user clicks the submit button a post request is sent to the back-end tool (PHP in this casse; PHP is a back-end programming language). the back-end tool handles the information given and deals with it to your liking. the action attribute is basically telling the front-end (HTML) where to give the information to the back-end(PHP) which is in the form of a URL.
i highly suggest trying out this example on W3schools :
https://www.w3schools.com/tags/att_form_action.asp
I see you want to send your HTML form data to a PHP script. You can use WAMP server or XAMP server to do this locally. You should use the PHP script file path as the input for the .
For instance,
Home.html
<HTML>
....
<form action="process.php">
...
</form>
</HTML>
So, when you submit the form , the form data is passed onto the PHP file which you can access using a $_[SUBMIT] super global array in your PHP script.
Check github for projects on HTML,JAVASCRIPT,PHP.
Here's one to start: https://github.com/kristej/Uniform-Database-Management.git
If you are sending the data to an online server, you need to own it to process it. Hence try it out locally first.
I have lots of images with filename as an identifiers. Each image has to be seen by users online and they can give a score/rating. How can I collect the data?
I have done it through Excel and collected the data manually. But now I am looking for an online based method as I know basic html and have access to a webserver. Please someone point me in the right direction or place for information.
For this you need to run some backend script where you will pass the value of the image clicked and doing some database function you have to store it in your database.
This is a vast subject. For example you can store data in database (MySQL for ex.) and generate html pages using server-side language (Python, Ruby, PHP, ext.). And users interact with the server through the html pages. Your images information will be stored in database and change with script on server-side.

I'm building a Phonegap application and i'm planning to set it to work in both Offline and Online mode, the idea is to get JSON Data from a PHP server side script and show it in the application, these data contains text, images so my question is is there anyway to set a dynamic cache manifest or any other way in a way that the user can see the already loaded data when he's offline, like caching the json result itself or anything else you can help me with
thanks
What do you mean by "work in both Offline and Online mode"? Are the users able to only see the user created data or can they modify it too? Is it correct to use a Manifest to control caching of user created data? I would have thought you should only really use it for caching the application templates and code. In any case I think you'll probably need something that you can exert more control over, something based perhaps using WebSQL, IndexedDb or LocalStorage.
I have been working on the modify-it-too question for many months and have a solution in the form of javascript(phonegap) <-> server synchronization that works somewhat like a version control system, with version numbers and conflict resolution. There's some pretty great docs and demo on the GitHub page and you can even see a presentation courtesy of SkillsMatter / LondonAJAX.. Currently there is only a JS/Node based server but I will probably do PHP based server because that's my day job If you look at the server code it's pretty easy to implement.
BTW I would use a different method to store the images, why not just download them and store them in a File, I don't know the storage limits, but I bet that is the way that Phonegap will let you get away with most.
I am building a website with ROR 3. I need to provide a page to my clients wherein he could edit his pricing info regarding the application. I am quite confused on how to do this. The pricing page needs to be displayed as an html table with different columns which has got the pricing info.
I am thinking of different ways to do this.
1) Allow the client to create and upload an html page and then save it as a file in my public directory and render as an when the client clicks on the pricing link.
2) The clients may not have bare technical knowledge, hence make the client upload some other formats like Word, Excel etc and then parse it and store it as an HTML file in the public directory.
3) Provide the client with some real time editing tools where in the client could edit in a fixed format, and after wards save the file and render it later.
Also, I wouldn't like to store these infos in my database. There would be quite a few number of clients and hence managing all these data in my database would become cumbersome. Storing all these as plain html files and rendering it later would be the most ideal thing for me.
There might be other better steps in doing this as well. Could you please suggest which might the better, or any other option that could suit my needs? Basically I would want my clients to have a mechanism where they could provide there pricing details, edit it later and display it back as an html table, all this without using an Database backend. Any suggestions would be mostly appreciated.
Good way is Excel(csv format).
You can do PHP with Excel. I thing this is the best solutions for your requirement.
Try this.
http://php.net/manual/en/function.fgetcsv.php
If you are give authority to user to change edit contain and you have to used " CSV or Excel" please see these links:
Importing CSV and Excel
Exporting CSV and Excel
If you really don't want to use database then you can use YAML as a structured storage.
e.g. ( you, most probably, could come up with a better structure )
SMS_Pack:
Sl_No:
1: 10000
2: 25000
3: 50000
You can read those .yml files and parse them as hashes. Should be fairly easy to represent that hash as a HTML table.
For the creation, I'm sure you can come up with some dynamic form input. Or to just let the client send this kind of file ( which might not be the best solution ).
But it just might be easier to manage all of this information within a database.
I have created a HTML5 webapp that runs quite nicely on most smartphones. Program can accept input from a user, store the information, display it, edit it, delete etc. Works fine.
I was wondering if there is yet a standard way fo sychronising this information with a remote MYSQL server, heck at this point I would settle for being able to post the information directly to a remote server, completely skipping localstorage.
I have looked at the websqlsync on github, but having limited success getting it working.
Any guides, working examples, tutorials or general pointers or best practice at getting html5 localstorage onto a MYSQL server greatly appreciated.
Why don't you save the localStorage object as a JSON string, and pass that to the remote server? What do you want to do with the data on the server?
