solved. Thanks Dan, this was pretty much the solution I came up with. Thank you Gunawan for the idea that got the ball rolling as well Onochie On 3/16/07, Dan Shirah <mrsquash2@gmail.com> wrote:
Try something like this: ****Your query here to get your dropdown values**** ** *// This first option value will set your default dropdown to display as blank* echo "<OPTION value=\"\">--SELECT--</OPTION>\n"; *// This will create a loop to return each option of your dropdown* foreach ($query_result as $q) { *// This if statement says that IF the value in your database matches your $_POST(selected) value then mark it as SELECTED*
    if ($q['my_column_value'] == $_POST['my_selected_value'])
      echo "<OPTION value=\"{$q['my_column_value']}\"
SELECTED>{$q['my_column_value']}</OPTION>\n"; *// This else statement will return your default(unselected) dropdown list if it can't match the selected value with a value in your database*
    else
      echo "<OPTION

Hello Gunawan On your first comment, im not sure what you were referring to when
you
said
it is a js problem on your second comment, i am talking about the user entered data.
data
submitted by the first submit button will always be predefined by
means
of
the user using a selection box, the data im concerned with checking
is
the
input boxes he will be seeing. and this wont necessarily be
username/pass.
and im trying to do this in php if at all possible. on your next comment, (6) i am talking about after i vertified the
validity
of the user typed/entered data, i will enter that into my db next comment - i knew this would be hard to describe, but i'll try
again.
this is to be done all on one page. and ive tried using something
like:
value=\"$_POST['name']\"
but i am having problems keeping the initial drop down at the
selected
choice, so whenever either submit button is pressed and the post
goes to
php
self, the drop down is refreshed back to its starting value, which
is
NULL hahaha.. that's simple.. drop down menu always return to the null because u don't give selected on one of option. i have a function (build in) that's answer your problem.. if you on hurry.. i'm sory, i cant give it now.. my skrip in other comp.. <select> <option value="base" selected>sale options</option> <option value="base2" >Buy options</option> </select> try this on offline i believe.. the first you enter the page.. the sale option will be selected now add 2 option then try one of the option you add have selected.. what happen next you will see the default will be change, remember erase selected forgive me.. i think it matter of js but it matter of html. fyi.. try using ajax .. i believe it make your life for comfort.. (since it don't need to refresh the page) and make your skill up.
I hope that helps define my problem a little more Onochie On 3/16/07, Gunawan Wibisono <landavia81@gmail.com > wrote:

Hello, and I would like to thank everyone that attempts to help
me
out.
I
have looked long and hard online before I resorted to this. My problem is that I have a page that relies on multiple submits
and
data
from what was submitted. example: // 1. some sort of drop down // 2. submit button // 3. display data retrieved from database // 4. user enters more information // 5. second submit button, run checks to vertify all data is
entered
u mean when clicked.. the info like username are check whenever is
valid or not?? perhaps u should try ajax
// 6. enter data into database
i don't get it what u mean in here??
The problem is in step 5, when the user hits the second submit
and
data
is
checked before db submission, I am losing the data displayed by
the
first
submit button
hmm i don't get it by reading at the first. i think in the 2nd
page u
should try to make <input type=hidden name=user value=landa> this input contain what previous data enter... foreach($_POST as $nm=>$val){ $txt.="<input type=hidden name=$nm value=$val>"; } echo $txt;
This is what I have tried ive tried using POST and SESSION variables to display the data,
but
this
doesnt work. this is because in my code i have an if isset
statement
to
check if submit has been pressed, then the variables are
retrieved
from
the
db and used. when clicking the second submit button and checks
are
done,
the
top portion of the page of information retrieved by the first
submit
are
nothing but blanks because the first submit is no longer set
(using
isset)
my next idea was to save the variable selected in the first drop
down
(step
1) and requery with this selection at the second submit button
to
retrieve
and redisplay the data. this did not work because this variable
was
set
back
to "" because the drop down resets itself on each submit.
disabling
the
drop
down if the first submit is set and then setting the variable
did
not
work
either because when the second submit is hit, the first submit
is no
longer
set, so the drop down is displayed, the variable is set to ""
and i
get
nothing in my variable. this also was the case if i made it a
global
variable.
i wish to see the offline from your pages.. if able send to me
so basically i have resorted to just googling things and trying
out
different arrangements of code to no avail. I need a way to hold
the
data on
the top half of the screen while the bottom half is being
manipulated.
any,
and i mean any help at this point would be GREATLY appreciated!
Thank
you.
