passing javascript variable to PHP

[Anon]

I'm trying to pass some javascript variables to php. Is there any way to do this w/o forms, w/o cookies?
I tried it with an IMG-tag:
<IMG SRC="test.php?id=24323&showme=true">
doesn't seem to work.

I'd like to set up my logging-script for other people who ain't got no php-possibilities on their server.

Any idea?
thanx a lot!

You can pass javascript vars via a url.....have the script append to the url and then the vars will available to php as normal.

<script>
document.write("<a href='test.php3?var1=" + var1 + "&var2=" + var2 etc..);
</script>

then php can use these as $var1 etc.

hey scott
that's not what I'm looking for
I don't want to click on a link to run the script. my javascript schould send the variables as soon as you enter the page without any interaction. Why does my IMG-Tag not work?

here's how thecounter.com does it. - probably no php-script:

document.write("<IMG BORDER=0 SRC=\"http://c1.thecounter.com/id=425413"+x+"\">")

where x="&referer=&size=1024&colors=16&java=true"

Actually....i think the counter.com has changed to php....anyway....it should still work.

I think there is a column on PHPbuilder by Tim, about having a counter on non php pages....which uses the 1x1 pixel image idea. Whether you have php physically create the image or not it should still work nicely.

Once you have set up your image tag with all it's vars tacked on to the end, php should be able to use them quite easily.

Check out Tims column.

hey Scott
thanx a lot! you were great help!
that's a nice article!

actually it was working all the time... dumb as I am, I didn't recognize it.
the 1x1 pixel trick was what I was looking for. Sorry about making such a big thing out of it, it was working from the beginning. 🙂

just one more question: I'd like to return an image from the php-script. how should I pass it over?
echo("<img abc.gif>"); wouldn't work as I cannot print any html-stuff inside an IMG.

thanx

Without using a php server to create the image I doubt that you can....hence the reason for making it a 1x1 pixel gif.

Are you sure you can't just echo an image from a php enabled server and have it displayed in the html page?

The counter do it using javascript.

How about if you go

<script>
document.write('<img src=blah.php3?var1 etc etc');
</script>

The have the php script print out a javascript which prints something like;

print("<script>document.write('<img src=counter.gif>');</script>");

I guess its no dif to just printing the image using php.
