basic php/html question..

netooio

I have a webpage with an html hidden form field..

I set its value when the page loads...

<INPUT TYPE=HIDDEN Name=TutorialNumber Value=<?php echo $_GET['Hidden1']; ?>>
This statement works correctly, i have checked..

I want to know if farther down in the same page, i can read the value of that Hidden form field in php that I set at the beginnng
of the page..
somethin like:

<?php if ($TutorialNumber == 1)
do this;
else if ($TutorialNumber == 2)
do that;
?>

Obviously i have tried doing it the above way and it doesnt work...
I've tried playing around with it quite a bit and i am stuck..
Is it possible to even read the value of the hidden form field?

manjit

if i understand it correctly the code will look like this

<?php if ($GET['Hidden1'] == 1)
do this;
else if ($GET['Hidden1'] == 2)
do that;
?>

I know that I can use the $_GET['Hidden1'] in the if statement...
but I need to use the TutorialNumber hidden form field for a reason.

I want to be able to use the value assigned to the HiddenFormField in this currentpage i'm working on which is called TutorialNumber...

Hidden1 is a hidden form field I have in a previous page I use it to set the value of TutorialNumber when this current page loads.. sorry if that is a little confusing...

Here's what i'm doing..
I create a new hidden form field when the page i'm working on loads called TutorialNumber assigning it the value of Hidden1 from the previous page.

What I need to know is if I can read the value of TutorialNumber in php using the TutorialNumber hidden form field somehow.

If that is still confusing, i can try to post a little more code on what i'm doing.

Hey I dunno whether your problem is as simple as I thought but, if you are trying to get the value you have previously set in TutorialNumber hidden field, dats easy, bcoz the value of TutorialNumber is derived from and the same as $_GET['Hidden1'], isnt it?!

Yeah, its IMPOSSIBLE to do what you're asking without a form submit.

Seriously though, look at what people are telling you... the value of that hidden form field MUST be the equal to be value of that $_GET variable... unless you changed it yourself.
