[SOLVED] Post a variable to the same page

oceans · July 3, 2007

Dear People,

I am posting a form onto itself to verify input entry, I can get the value of text box and combo box, but how can I get the value of a “variable” (don’t use cookie or session)?

That is if I use

if ($_POST["$Variable"]!=1){}

Thanks.

oceans · July 3, 2007

Can any one please help me, thanks.

Not sure if I totally understand what you need, but you could use a hidden field in the form:

<form>
   <input type='hidden' name='variable' value='some_value'>
</form>

Is this what you need?

oceans · July 3, 2007

Thanks, I am trying, give me a while

oceans · July 3, 2007

NOT working,

I will give you my situation..

<?PHP
if ($_POST["Flag"]==1)
{
bla bla bla
}
else
{
bla bla bla
$Flag=1;
}
?>
<input type="hidden" name="Flag" value="<?PHP echo $Flag; ?>">

I want to transfer this Flag value for if else operation that is all

Thanks

no_one · July 3, 2007

Oh,

$flag = $_POST['Flag'];

???

oceans · July 3, 2007

I did this, to do somthing on the first run of the page, than on the second run do somthing else.

I was hasty with my earlier reply, the idea works, but the the process goes to if ($_POST["Flag"]==1)

on the third run not the second. any possible reason.

you want my modified code?

oceans · July 3, 2007

<?PHP
if ($_POST["Flag"]==1)
{
bla bla bla
}
else
{
bla bla bla
$Flag=1;
echo "<input name=\"Flag\" type=\"hidden\" value=\"$Flag\">";
}
?>

no_one · July 3, 2007

What else is there to this code? Or is that it?

oceans · July 3, 2007

Dear Friend,

The page is long thus I did an extract for you.

Actually there is nothing else out of this <?PHP ?>

oceans · July 11, 2007

Dear People,

I tried to use one of the members advice but I can't get to post the value is there any thing wrong?

teng84 · July 11, 2007

teng84 · July 11, 2007

where can i find this $_POST["Flag"]

or the form name flag

oceans · July 11, 2007

Sorry, The Flag was on the old message, please ignore "Flag" and take "Local_session_id"

thanks..

please go through my new code and you will find when I echo the post does not come out..

teng84 · July 11, 2007

echo $_POST["Local_session_id"];

echo "<input name=\"Local_session_id\" type=\"hidden\" class=\"FieldValue\" id=\"Local_session_id\" value=\"$session_id\">";

which is not comming out

oceans · July 11, 2007

value for

"

echo $_POST["Local_session_id"];

" on the second run

because on the first run

"

echo "<input name=\"Local_session_id\" type=\"hidden\" class=\"FieldValue\" id=\"Local_session_id\" value=\"$session_id\">";

"

would have set a value for "Local_session_id"

MY intentsion is very simple, when I post the page to itself I want to carry the value to the same page, pelase help with your method or modify, please do not use session or cookie, thanks

teng84 · July 11, 2007

look this must be already set echo $_POST["Local_session_id"];

because thats where the hidden fields rely so the problem is i guess not on that

page its on the page where you get this echo $_POST["Local_session_id"]; is there a form name

Local_session_id then thats causing trouble

oceans · July 11, 2007

I am doing all this because in browsers when you open many window all the window use the same session file, and one of our member was very kind to tell me to pass session file name to each page but when I do post on to itself passing cannout be done that is why i am trying to retain the faile name this way, can I give you a fuller page and will help me with the code, I am really frustrated because I am infront of my screen for hours getting no where...
