Actually a Javascript question, but I seem to be in a rare good mood
today, so you're in luck. In the snippet below I've also fixed some
syntax issues that tell me you really don't know what you're doing. On
the other hand it could just be what you wrote in the email and not what
you are actually trying to run. Either way I suggest you Google for a
beginners tutorial on PHP to learn some basics.
?php
$counter = 0;
while(query) //here the query is opened [Stut: If you say so!]
{
?
table
tr
td?php $query-name ?/td // record from database
tdPlease fill in your age:/td //text
tdinput id=age?=$counter? name=age type=text/td
//textbox,
tda href=# onclick=location.href = 'otherform.php?age=' +
document.getElementById('age?=$counter?').value +
'name=?=urlencode($query-name)?'; return false;Save Age/a/td
/tr
/table
?php
$counter++;
}
?
What this is doing is assigning an ID to each age textbox, that allows
the onclick handler for the link (which you had not closed properly or
given some text to display) to get the value and add it to the URL it
links to.
I suggest you run this and compare the source file and the output to see
what is server-side and what is client-side, because I don't think you
understand the difference yet.
Enjoy.

how can i get the value from the textbox? i don't have form tag
if i have 50 records, there are 50 textboxes named age right?
If you want 30 boxes named 'age', then you should name them like:
name=age[] or, possible, name=age[42] where 42 is the ID of the
record whose age is being displayed/input.

Line 79 is not part of a function or class. It is the first reference to
$forum_admin in the script. The other two are within functions and the
first call within those functions. What's being assigned to both of them
are either in the function call itself or globals.
I do have globals turned on.
you mean register_globals? Turn it off unless this breaks things in a
major way... even then you should consider recoding if that's feasible.
Should I worry about any of this? The pages seem to be working fine? Is
this going to slow things down? Should I just turn off the logging of such
errors, if I can?
uninitialized variables + register_globals is usually a bad
combination... especially when we're talking about a varaible like
$forum_admin.
http://.com/forums/post.php?forum_admin=1user=whoever
In a simple case the above can happen and someone gains admin rights...
in worse cases you end up with SQL code dropping databases...
Thanks for any help. My log files are in the gigabytes with 90% of that
over the last month.
ignoring the E_NOTICE errors is a good idea on a production site anyway.
That being said... I would try to fix the code so that the notice
doesn't get produced in the first place.

[PHP] Re: undefined variable notice - how to furn of
Everything works fine, just now I'm getting Notice messages for every undefined variable or undefined index in arrays.. So now I have to use issset() everytime to avoid this messages... you would initialize your variables in the beginning of your scripts. With that, you don't need isset(). ..is there any way to turn this messages off, because if prior versions I never got them..?? ok, the other guys have answered with error_reporting(E_ALL ~E_NOTICE) or error_reporting(E_NONE). But don't you think it would be a best practice to set error reporting to E_ALL and initialize your variables ? your script would work, regardless of the configuration of php.ini, and would be more portable. error_reporting(E_ALL) and register_globals = off are IMHO a good way to have better code. In fact, I use error_reporting(E_ALL) on my test server, and error_reporting(E_NONE) (or a file log) on the production one.

I have been sloppy in teh past and just used if($submit) blah blah blah not sure of ramifications, but seems to work unless $submit is false or not set. again, take with grain of salt, other suggestions (especially isset) are much more certain.
