Carrying Post Variables

geat

I'm developing a web site that involves data being entered by the user over a series of pages (built using a single php script and selecting the appropriate form to display thanks to a posted flag).

How do I carry all of the variables from subsequent pages on right until the end (there's 80 variables in all, over about 7 pages)?

you can post them into either variables (assoc array) or hidden form values, both will do the same trick eg

$formVar["name"] = $_POST["name"];

<input type="hidden" value="<?php echo $_POST["name"]?>">"

Can I take the array of posted variables in bulk and add them to the data that is to be posted when submit is clicked?

Anyone?

JakesSA

You have got to stipulate it. Once you have got all your form variables, post it....the use a loop to populate the new hidden values or variables

//from your first form
<method="post">
<input type="hidden" value="John" name="firstname">
<input type="text" value="">

//your second form

foreach($_POST as $varname => $value)
$formVars[$varname] = $value;

//now you can populate what ever you like

Is that $formVars a reserved array or not? It doesn't seem to work... I need access to the array of variables that will be posted on submittal of the page.

i am lil confuse here is the $HTTP_POST_VARS carry variable to next page

<form method>
$HTTP_POST_VARS['username'];
<submit>
</form>

print("".$HTTP_POST_VARS['username']."");

it will print username right???

Yeah - but I want to post $HTTP_POST_VARS from the second page to the 3rd, without having to loop through the array and creating a load of hidden inputs.

There must be a PHP variable that carries the name/value pairs that are going to be posted, surely?

JakesSA

when you use post ($_POST or $HTTP_POST_VARS) to post to another page, it comes through as an array....all you are doing is reseting the name and the value with the new one, into an assoc array.

Now that you have a wonderful array, there countless ways that you can play with, to poulate fields or $variables

post - > reset -> fill / insert / mail

hope that helps

Check out the "serialize function"... Probably one of the easiest things to do is to serialize the $POST array, shove it into a hidden variable ( make sure to us html_specialchars to change any " to " ), then unserialize the hidden var on the next page, add the rest of the POST to it, reserialize, lather rinse repeat...

Hi.
Is there any way to retreive variables for which you don't know the name? Or even better to get a list of all posted variables passed through?

geat

Yeah, it's pretty easy...

You set up a list loop, try the following:

rest($HTTP_POST_VARS);
while (list($name, $value) = each($HTTP_POST_VARS)) {

You set up a list loop, try the following:

reset($HTTP_POST_VARS);
while (list($name, $value) = each($HTTP_POST_VARS)) {
echo $name .' = '. $value;

This will print the name of the posted variables, and their corresponding values.

If you're using this inside a function, remember to

GLOBAL $HTTP_POST_VARS,

or better still, if you're using PHP4, use

$_POST instead of $HTTP_POST_VARS

That's an auto-global!
