multiple forms fro the same php file.

[Anon]

hello

I'm trying to have some sort of plan which include 4 steps. In each of those steps values are being assigned to variables. By clicking next people go through the steps. My problem is that i don't know which variables are gonna be know on the form action sheet. All assigned variables or just the ones on the last step.

can somebody give me a hint

THANX

It might be easier if you use four pages instead of one. Then you could pass values from the earlier pages to the next ones in hidden form fields. You could do that anyway with one big page, but it would be harder to keep things straight.

Just a minor comment. An ok method to pass on variables to a new (or the same) page;

$fields = "field morefield mostfield lastfield testfield";

foreach (explode(' ', $fields) AS $key => $val)
print '<input type="hidden" name="'.$val.'" value="'.$$val.'">';

I am using four pages. on each of those pages (called step1, step2, step3, and step4) variables are defiened using input forms. The variables should be known in the end php file called calc.php They don't have to be known in the the next step files just in the final php file

How should i do that.

could you clarify what you said:

$fields = "field morefield mostfield lastfield testfield";

foreach (explode(' ', $fields) AS $key => $val)
print '<input type="hidden" name="'.$val.'" value="'.$$val.'">';

i'm not sure what you mean exactly. Are you talking about having all php files and than include the defined variables by using the hidden variables.

here's a better expl. of my situation:

I am using four pages. on each of those pages (called step1, step2, step3, and step4) variables are defiened using input forms. The variables should be known in the end php file called calc.php They don't have to be known in the the next step files just in the final php file

Well,

the object of that code is just to build the hidden inputs. If you have 10 textfields looking like this;

<input type="text" name="firstname" value="">
<input type="text" name="surname" value="">
...

And then submit these values to a new php-file (or the same one), you want to bring these variables on to the next page. So, list them all up in one single variable (only the fieldnames);

$fields = "firstname surname email phone";

(add all the ones you want to bring along). Now, explode this text string on ' ', and build a set of hidden inputs from them.

foreach (explode(' ', $fields) AS $key => $val) {
// Now we are working with a single 'word' from the $fields variable.
print '<input type="hidden" name="'.$val.'" value="'.$$val.'">';
}

So for each word in the $fields, this will output the text;

<input type="hidden" name="fieldname" value="(value of $fieldname)">

---

In other words,

step1.php

<form action="step2.php">
<input type="text" name="firstname" value="">
<input type="text" name="lastname" value="">
<!-- add submit button -->
</form>

step2.php

<form action="step3.php">
<input type="text" name="email" value="">
<input type="text" name="phone" value="">

<?php
// Bring along values from step1.php
$fields = "firstname lastname";

foreach (explode(' ', $fields) AS $key => $val)
print '<input type="hidden" name="'.$val.'" value="'.$$val.'">';
?>
<!-- add submit button -->
</form>

step3.php

<!-- add form & new fields -->

$fields = "firstname lastname email phone";
<!-- add foreach explode code from above -->

Hope that helped 😛

Nice technique.

[tomhath]

If you don't store them in Session variables you'll have to carry them along through every form as hidden fields (Terje gave a nice way to code that).

Have each form action submit to the next form in sequence, all the hidden fields will be POSTed along with the ones displayed.

Keep in mind that a user can hit the Back and Forward buttons, although that shouldn't be a real big problem. Also handle what happens when someone just types the page name in their browser instead of posting.
