forms setting session on completion of a page
Posted on 2004-10-12
Hi,
Please can someone point me in the correct direction. I am building a from from data coming in from any oracle db, from there, a table is build, and I am storing the information on a form. This is fine, and I can move across the four pages, of user input needed for the select statement, on the client site, the variables are being set correctly, and when I use the "get" method of moving between pages, I can see the correct HTTP_VARs being set. But, When I try to add all the information together, so the select can run, the last page can not read the HTTP_VAR information, even though I can read it from ther URL line. I have tired to place the infomation I need into a session file, but as that is set up before the user select the field, it does not contain any useful information. I have attached the code i am using below to build the table.
I am going arround in smaller and smaller circles here. I am using PHP 5 with register_globals off, as per the php suggestion.
Thanks in advance
Tim

If you are trying to get values from the URL (with the GET form method)
You should be using $_GET or $HTTP_GET_VARS
and not $HTTP_SESSION_VARS
is that what you asking?

Are you sure this $HTTP_SESSION_VARS['$sess_
$HTTP_SESSION_VARS[$sess_v
'$sess_val' is the string $sess_val not the content of $sess_val
$HTTP_SESSION_VARS[$sess_v
'$sess_val' is the string $sess_val not the content of $sess_val
Hi minichicken,
sorry, I did not clean up the code completely, I have been tring all diffenet way.
When I change the posted PHP to $_GET I then get on the select Page
select2.php?p-400=w&p-401=
p-411=w&p-412=w&p-413=w&nu
which is want I would expect. But then when I try to read it, via
while (list($key,$value) = each($_GET));
echo "$key = $value"
for example, there is no output
Where I would have expected to get something like p-401=w for example.

i think you should try this to see if there any values posted at all:
print_r ($_GET);
or
print_r ($_POST);
if you get an output like : Array ([p-400] => w , [p-401] => w , .....)
if no value is passed at all then: Array()
print_r ($_GET);
or
print_r ($_POST);
if you get an output like : Array ([p-400] => w , [p-401] => w , .....)
if no value is passed at all then: Array()
Hello,
I get Array ( [p-400] => w [p-401] => w [p-402] => y [p-403] => n [p-404] => w [p-405] => w [p-406] => w [p-407] => w [p-408] => w [p-409] => w [p-410] => w [p-411] => w [p-412] => w [p-413] => w [number_of_sele] => ) =
I get Array ( [p-400] => w [p-401] => w [p-402] => y [p-403] => n [p-404] => w [p-405] => w [p-406] => w [p-407] => w [p-408] => w [p-409] => w [p-410] => w [p-411] => w [p-412] => w [p-413] => w [number_of_sele] => ) =
If you are using each make sure the array pointer is set to the start. So try:
reset($_GET);
while (list($key,$value) = each($_GET));
reset($_GET);
while (list($key,$value) = each($_GET));
hello,
I tried the reset($_GET); i still do not see any of the url line.
I have added
echo $key . "=" . $value . " <b>" ;
echo '$key' ;
echo "$key" ;
just to complete the output, I then get the third one $key outputed to the screen

I think hernst42 is right, you will need to reset the array. Look at this example straight from the PHP manual.
**************************
<?php
$fruit = array('a' => 'apple', 'b' => 'banana', 'c' => 'cranberry');
reset($fruit);
while (list($key, $val) = each($fruit)) {
echo "$key => $val\n";
}
?>
Outputs:
a => apple
b => banana
c => cranberry
After each() has executed, the array cursor will be left on the next element of the array, or past the last element if it hits the end of the array. You have to use reset() if you want to traverse the array again using each.
Because assigning an array to another variable resets the original arrays pointer, our example above would cause an endless loop had we assigned $fruit to another variable inside the loop.
