PHP + JavaScript variable

Anon

Hi all,

I'm fairly new to PHP and i think i have just a minor problem. I want to declare a Javascript variable within a PHP script, is this possible?

example

Javascript blablabla (

javavariable = 1;
var test="<? $phpvariable[javavariale] ?>";

}

Could someone help me with this? That would be a big help, thanks already.

What's to help with? It looks like you're on the
right track. You can have PHP write anything at
all to the output html, including javascript--
or, for that matter, completely invalid html
that will never display properly. PHP itself
doesn't care. :-)

Thanks Kirk for your quick reply.

I tried it but it just keeps me bothering for an hour now, it still doesn't work but i'll keep on trying...

Ahh, what do you mean by "doesn't work"? What
do you see when you look at the source html in
your browser?

Also, you might want to post some of the actual
code here; your original looked like a very brief
excerpt (e.g. I doubt 'blablabla' is really the name of
the Javascript function.)

Thanks for helping me out Kirk.

The tempteller is a javascript variable but i want to recall it within the PHP tags, which are within a Javascript source again...

This code is within the Javascript tags:

var tempteller=1;
var temptellermax=5";

while (tempteller < temptellermax) {

var folder="<? echo $folder[tempteller] ?>";
var link="<? echo $link[tempteller] ?>";
aNode=new Node(folderNode,1,1,folder,1,link,1);

tempteller=tempteller+1;

}

If I was ment (´cause you wrote blablabla as I did but with another RE🙂:
The source is what I wrote.
<? echo ("bla, bla, bla") ?>
and it is exactly the same way written on the browser. The Browser should say:
bla, bla, bla
I presume.
Thanks for your help in advance,
Jo.

You've got some serious confusion going here. 'tmpteller'
means nothing to php. It's not even inside the php
markers, but if you did turn things around and have php
write all the content via echo(), it would still be nothing
but more text as far as PHP is concerned.

You need a clearer understanding of how PHP works. When
the client requests a PHP page, it gets processed by php
at the server instead of just being sent straight from the
filesystem to the browser. But if you called a file .PHP
but didn't include any php tags in it, then it would eventually
flow to the browser byte-by-byte identical to the way it
would be send if it were called .html.

All php is doing is generating (or passing through untouched)
html that gets sent to the browser. Of course that can contain
javascript or anything else you want, but at the stage of PHP
processing it, it's just text being produced as far as PHP
is concerned--it certainly doesn't execute any of the javascript.

Maybe people need to take a short course in 3270/5250 block-
mode terminals before they start web programming. It's very
similar in it the way it operates--the server (or mainframe)
generates a set of data that is sent to the screen. The screen
then allows the user to interact with the data, completely
without the server/mainframe being involved in any way.
Then, when the user presses the enter key/send button,
the entire set of results is sent back to the server/mainframe.
