arrays question

[Anon]

Hi all
I have a form that submits to PHP_SELF storing the collected data in an array and then displays the form again with the intention of storing more data in the array.

Will it work like this
arrayvar[1] //data from form 1
arrayvar[2] // fata from form 2

Or do I need to use sessions or someething?

Thanks

Nick

Hi,

you need to store the data of form 1 in form 2 e.g. into a hidden input field...

something like this should do it....

<form action=< ? echo $PHP_SELF ?>>
<input type="text" name=arrayvar[]>

<? while (list ($key, $val) = each ($arrayvar)) {
echo '<input type="hidden" name="arrayvar['.$key.']" value='.$val.'>';
} ?>

</form>

Yep, thats what I thought would come back from asking, I can see that working if the script ends with form 2 but what if the script keeps throwing up the forms untill the user decides it's time to quit?

I think sessions will have to be the way forward unless I want to commit the input to the DB on each submission (possible but wasteful in this case).

I'm building a class for this section of the site and have heard it's possible to send the object through sessions (then I could access the array regardless)

If you have any further comments or insights let me know

Otherwise thanks for the help!
