Catching variable's from form

[SmilieBG]

Hello all. My first post, so please be gently to me 🙂

Ok, here we go:

I have 2 pages: input.php and proccess.php

On input.php I have 2 forms, from which:

form1: is a javascript form, with one text input box. User can type a number from 1 to 15 in there. When submitted, form triggers javascript (JS) which creates 3 table elements (3 text input boxes names: input, value_1 and value_2). There three input boxes are then inserted into form 2 on input.php using 3 layers. There layers correspodent to the variables from JS.

Furhter, user fills in those 3 values and form 2 sends those to proccess.php. There I can read them by reading variable's input, value_1 and value_2.

My problem is:

if user types number 3 in form 1 (JS form) on input.php, then will JS create 3 x 3 variables:

input 1:
value _1 1:
value_2 1:

input 2:
value_1 2:
value_2 2:

input 3:
value_1 3:
value_2 3:

JS in form 1 on input.php is doing this by running:

for (i=1, i <= number_given_in_form_1, i++)
{
create input boxes
}

So, the problem is:

how can i determine in proccess.php how many input, value_1 and value_2 variable's do I have to read?

I can not read the value user gave in form 1 as this is not passed. Only info from form 2 goes to proccess.php.

My idea is to put value from form 1 (number from text field), passed through JS into hidden text field in form 2. But question remains, how do i do that?

Geez, I hope you ppl will understand what I ment :-)

If not, please ask I will gladly give more explanation!

Thanx in advance.

Cheers,
SmilieBG

1. YOur post is too large and broad. Start with a simpler problem; If you can express the question well, you'll very often figure out the answer (or the answer when it comes won't be lost on you).

2. Use tools. Start by adding Action="new_window" on the form tag, so that you can keep submitting until you get the problem solved, without hitting back.

3. use this code at the head of process.php:

echo "<pre>";
print_r($_POST);
echo "</pre>";

this will show you the raw form of your post as you upload and make corrections.

4. OK, I see what you want to do at the bottom, on form 2 do this:

<?php
foreach($_POST as $n=>$v){
echo "<input type='hidden' name='$n' value='".htmlentities(stripslashes($v))."'>\n";

}
//note use of the htmlentities and stripslashes function so that your input gets passed cleanly.
?>

5. Anytime you start using extensive JS on your forms, you'll get a good lesson communicating PHP values to JS initial conditions (especially when updating existing data via a form).
