Hello!

Does anyone knows how to "copy" content of variable from java script to PHP
variable.
For example:

JAVASCRIPT:
<SCRIPT>
....if (something...blabla)
{
name="JACK";
}
</SCRIPT>

Now I want to copy "JACK" into PHP variable $name.
Can I do that?

THANK YOU FOR REPLY

it all depends on what you are trying to do, I mean you can't just
copy it, you must send it, the usual way is with a form, or using XHR,
or an iframe, or a script tag, or an image.

<form id="form" action="php_script.php" method="get">
<input id="name" name="name" type="hidden" value="" />
<input name="submit" type="submit" value="submit" />
</form>
<script type="text/javascript">
//name = 'JACK';
document.getElementById('name').value = name;
document.getElementById('form').submit();
</script>
if you dont want the page to change, then submit to an iframe

<iframe src="" name="iframe" style="visibility:hidden" width="0"
height="0"></iframe>
<form id="form" action="php_script.php" method="get" target="iframe">
<input id="name" name="name" type="hidden" value="" />
<input name="submit" type="submit" value="submit" />
</form>
<script type="text/javascript">
//name = 'JACK';
document.getElementById('name').value = name;
document.getElementById('form').submit();
</script>


XHR is too boring to write out, google AJAX.

<iframe src="" id="iframe" style="visibility:hidden" width="0"
height="0"></iframe>
<script type="text/javascript">
//name = 'JACK';
document.getElementById('iframe').src = 'php_script.php?name=' + name;
</script>

<img src="" id="img" style="visibility:hidden" width="0" height="0"/>
<script type="text/javascript">
//name = 'JACK';
document.getElementById('img').src = 'php_script.php?name=' + name;
</script>


then there's the script include in the heade

<script type="text/javascript">
name = 'JACK';
document.write('<script type="text\/javascript" src="php_script.php?
name="'+name+'><\/script>');
</script>

take your pick. Of course I should be in bed so all this could be
rubbish!

JavaScript isn't Java, the only thing they have in common is the four first
letters in their names.

You can't do that without reloading the whole script.

As shimmyshack points out there are a couple of different methods to do it,
AJAX is good if you only have to update a smaller area of your page, a form is
easy to make and quite good when updating the whole page.

THANK YOU!!
I have solved the problem,
I used "form":

<form id="form" action="php_script.php" method="get">
<input id="name" name="name" type="hidden" value="" />
<input name="submit" type="submit" value="submit" />
</form>
<script type="text/javascript">
//name = 'JACK';
document.getElementById('name').value = name;
document.getElementById('form').submit();
</script>

It works just fine.
