Re: [PHP] Re: posting form values doesn't work
Hi Øystein, PHP is interpreted on the server side, JS on the client side. I guess thats what you need to realize. Try starting with less complex stuff and just concentrate on one language at a time, in the beginning. Timo Am Montag den, 2.

If you submit a form, you will POST the variables to the same page (). The parser will only define variables at the start of a page. So, if you POST a page, PHP will define all the variables for you. What you are trying to do, is using the PHP variables before the form is submitted. That means that the parser did NOT define the variables for you. That makes sense, because the parser is running on the SERVER, and this Javascript code is running on the CLIENT. The client doesn't have the parser, so it can't define the variables for you. So getting variables using Javascript and PHP is NOT equal. Getting them in Javascript can be done by the client, like you do in your validation function. Getting them in PHP can only be done by the server. You cannot use these variables in Javascript code as $some_var.

Yes, you were right. Now a natural question. WHY? I don't understand your
explanation, since I thought it was equal, getting a field value using
document.answerform.name.value in javascript AND the variable $name in php.
I still use php in the location.href-part (it is as follows, the other was
faked: location.href=groups/answer.php
This opens the file groups/collectanswer.php.
So, why does it work some time mixing javascript and php, and not every
time?

[ CUT Javascript code ]
At first I thought is was JavaScript/HTML code, but I can see a little bit
PHP now ;-))
The reason that it doens't work is simple. The variables are only available
AFTER posting the form. Not during validation!
You should just use Javascript to fill in the name and group into the URL.

This is not Javascript or HTML's newsgroup. You should read some docs about
PHP/HTML before doing that, you're currently using Javascript for nothing.
