php and javascript together?

gamextremer2003 · #1 (**permalink**) 08-25-03, 10:46 PM

How can I make or send information to php from javascript? Maybe I need MySql help..I dunno.

Here's my problem, I'll make it really simple so that it won't take too much of your time to understand.

HTML----

link to external script
script = javascript src=1.js

JAVASCRIPT----

Make random number
Store number either by making a new array or num = randomnum and setting +num+ to the random number

PHP----
Write $num to text file.

and while all this is going, the page has not lost it's focus on the HTML file. Basically what I mean is that all this happens in the background.

How exactly would I be able to do this?

Any help would be greatly appreciated. Thank you.

Maybe you could have javascript open a window in the background running a php script using a GET variable to pass the $num variable?

To ask a stupid question, why do you want to do something like that in Javascript, when it's easy to get a random number in PHP anyway ?

Agreed, but he may need it to be done a number of times without reloading the page, doubtful but it's possible.

I've got a similar problem..

I have a javascript function that takes an array, but the array is filed with php vars... how do i get the js vars to have the php var values?

There are two issues here:

1. How to put PHP variables into javascript
2. How to put javascript variables back into PHP

Here is how I have done it...

1. Putting PHP variable into your javascript is easy, just echo them into the script wherever you normally would declare your script variables.

2. Putting the variables back into PHP is the tricky part. You need a script that will take the javascript variables and put them into variables that will be posted back to the server when the form is submitted.

Below is a simple example...

Code:

<html>
<head>
	function preProcess()
	{  
		document.tournament.post1.value = document.tournament.var1.value;
	}

</head>
<body>

	<form name="tournament" id="tournament" method="post" action="bracketsave.php" onSubmit="preProcess()">
	<input type="hidden" name="post1">

	// some js goes here using the variable var1

	</form>
</body>
</html>
