calling a variable in javascript from php or vice versa

[myname]

i need help with referencing variables from php to a javascript or vice versa.

my pages are written in php primarily. i needed a user response - therefore i used javascript and used confirm() to get the appropriate response.
the user response is needed inside the php for further calculations.

does anybody have any idea?

any kind of help would be much appreciated.
thanks,
:confused:

php runs server side and javascript runs client side

There is no point using a confirm as this just makes it harder, use a form and submit the form to a php script. Depending on the submit method (GET or POST) the data in the form will appear in the php superglobal $_GET or $_POST which are arrays the indexes of which will be the names you give your form element.

Hi

You can directly embed php in java script

like

{
<?php

ur php code


?>


}

You are using 2 different scripting languages, PHP and Javascript.

PHP runs server side and Javascript (normally) runs client side so by the time the browser has loaded a page the php has already run, the Javascript runs after the browser has loaded the page.

The effect of your code above is that the browser sees a page with the following in it

[html]
<SCRIPT LANGUAGE="JavaScript">
function test(){
hi }
</SCRIPT>

<a href="javascript:test();">test</a>
[/html]

"hi" is not valid Javascript so it doesn't work. You could have

[php]
<SCRIPT LANGUAGE="JavaScript">
function test(){
document.write(<?php echo '"hi"'; ?>);
}
</SCRIPT>

<a href="javascript:test();">test</a>
[/php]

or

[php]
<SCRIPT LANGUAGE="JavaScript">
function test(){
var string = <?php echo '"hi"'; ?>;
document.write(string);
}
</SCRIPT>

<a href="javascript:test();">test</a>
[/php]

<? $test = "test"; ?>

 <SCRIPT LANGUAGE="JavaScript">
function test(){
    var string = "<?=$test?>";
    alert(string);
}
</SCRIPT>
 
<a href="javascript:test();">test</a> 
 
 

this would be kind of passing a variable..

Hey,

Produce more incredible result if you write your script like this:

print
"<script language=javascript>
function test()
{
var string='$test';
alert(string);
}
</script>
";

<? $test = "test"; ?>

 <SCRIPT LANGUAGE="JavaScript">
function test(){
    var string = "<?=$test?>";
    alert(string);
}
</SCRIPT>
 
<a href="javascript:test();">test</a> 
 
 

this would be kind of passing a variable..
