JScript Value to PHP

[Rilt]

Hi! How do I move a JScript Value into a PHP Variable? Can somebody help?

[pyro]

Either submit a form, and read it via $_GET or $_POST (or $HTTP_GET_VARS and $HTTP_POST_VARS in PHP < 4.1.0) depending on the method you used for the form, or refresh the page with a query string attached and read it with $_GET...

Sorry but Im really new in JScripts. I have to ask you another question:

What do you mean by "or refresh the page with a query string attached and read it with $_GET... "? How should I do that?

[pyro]

First of all, do you mean JScript or JavaScript? I'm going to assume JavaScript as that is what I know, and that is much more common.

To get the value 10 into your PHP script, you could do it like this:

<script type="text/javascript">
var = 10; //variable to send...
window.location.href = "somepage.php?var="+var;
</script>

And then in the PHP script:

<?PHP
$var= $_GET[var];
echo $var; #will echo 10
?>

Hello pyro,

thanks for the quick reply.

I've tried your suggestion - but its not really what Im planning to achieve. Upon activating the script, it only jumps into the next page - 'somepage.php' (for example). I wanted that the value from the Javascript Variable would only be passed once I clicked on the submit button. Is that still possible?

Sorry for asking too much...

Yes, you can use either the POST or GET method with the form, and access the variables with $_POST or $_GET as I said earlier. I would use POST as it is more secure.

For example:

<form action="<?PHP echo $_SERVER['PHP_SELF']; ?>" method="post" name="myform">
<input type="text" name="field1" value="somevalue">
<input type="submit" name="submit" value="Submit">
</form>

and then this bit of PHP to get the value:

<?PHP
$field1 = $_POST['field1'];
?>

and, you can use javascript to set the form fields value...

<script type="text/javascript">
function setVals() {
document.myform.field1.value = "a value set with JavaScript";
}
window.onload = setVals;
</script>
