Posting Javascript to Database Via PHP

[Selacius]

In a previous topic I asked how I could create a script where the numbers were dynamically increased without having to refresh the page. Anyways I have that script all figured out now, and I intend on placing it in a form with other text boxes for which I will need to insert into a database. I am curious, how can I go from a code like:

<tr><td>Strength:<td><center><div id="counters">4</div><td><a href="javascript:increments()"><b><center>+</a><td><a href="javascript:decreases()"><b><center>-</a>

where counters is the actual value of the number I want to insert into the database. So how can I do this using forms? Or rather, how can I supply these variables (counters...) to a php via a form.

You want to insert the icremented number into a database using php without refreshing the page???There is only one way to do this that I know of...welcome to the world of AJAX.Read this article to understand what it is and how it works.http://rajshekhar.net/blog/archives/85-Ras...X-Tutorial.htmlThis is by far the best AJAX tutorial I have found.AJAX is basically a way to interact with teh server using javascript. It uses the HTTPXML object of the DOM to execute server functions from the client.

No I didn't say I don't want to refresh the page. What I said is that my incremental number code does not require the refreshing of the page. The numbers and other user defined variables will be in a form, which will be redirected to a php page when the user submits the form. My question is, what do I change in the code which I pasted in the first post to allow the values to be carried over by the form.

sorry for the misunderstanding.well assuming your final incremented value is now in a javascript variable called x... and you have a hidden field(input type="hidden" id="xNum">) in your form with the id xNum you can do this

document.getElementById('xNum').value = x;

now this will be sent with the form to your PHP page where you can retreive just like any other form field.

Tried it that way and for some reason it doesn't want to work. I don't know whats wrong with it.

Post your code and I'll debug it for you. There has to be something thats getting overlooked.

Due to the length of the code, I sent you a pm with it enclosed. Thanks for taking a look.

I just PM'd you the solution...if you want you could post it here for others to benefit.Good luck.

The code is a lengthy piece of work, but mainly it is a form element in which the user inputs a few user defined values and also can play around with some numbers as well. The numbers in this example take the shape of a character creation system for an online game. There are 5 stats to which the user can increase and in doing so these values also increase the players beginning Hit points. This then all gets submitted to a final page via a form where the information can be inserted into a database for use in the game. If this is in any way/shape/form what you are looking for, feel free to PM me and I will gladly send you the code along with information on how to modify it to suit your needs. Many thanks goes out to aspnetguy on this forum and a few other forum members belonging to other forums.
