Hi I need help!

Forgive me I am a PHP newbie. I have a small script that enables me to
send
a form from an HTML page. I want to use the HTML formatted form
because the
design of my website is complex, and I don't want to have to mess
around
with formatting a page using HTML within php. So basically the
"action" of
the HTML page sends the form to "ProcReg.php". This is the code:

<?php
/* Script name: ProcReg.php
* Description: Script displays all the information passed
* from a form.
*/
echo "<html>
<head><title>Registration Information</title></head>
<body>";
foreach ($_REQUEST as $field => $value)
{
echo "$field = $value<br>";
}
?>
</body>
</html>

-------

This is what I get as a "return", at the moment to a blank web page:

First_Name = First Name
Last_Name = Last Name
Address1 = Address Line 1
Address2 = Address Line 2
Address3 = Address Line 3
TownCity = Town/City
CountyStateProvince = County, State or Province
PostZipCode = Post Code/Zip Code
Country = 000
e-mail1i = Your E-Mail Address
email1v = Confirm Your E-mail Address
email2i = Your Alternative E-Mail Address
email2v = Confirm Your E-Mail Address
intcode = 000
areacode = 000
telnum = 000000
username = Username
password = xxxxxxx
mailinglist = Yes
clubfbd = Yes
B1 = Submit

---

I just want to know how I can modify the php code in the ProcReg script
so
that the instead of writing the "return" to a web page, it writes it to
variables or an array, so that I can call the data later in the same
script
to be checked?

I am sure I know how to do the checking, but not how to get the data
into
variables or an array.

Hi CB,

$_REQUEST IS an array , you just have to call it whenever you need to.

It is populated with NAMED rather than numbered elements which is
possibly where you are confused

the B1 element is the name of your 'button' and 'Submit' is the text
shown on its face.
the other values are the names of the fields and the values they held
when the submit took place.

If you want to put the values into another array, just use

$myArray = $_REQUEST;

but why bother ?

try
var_dump($_REQUEST);
to see all the details

Thanks Ron,

Let me just get this straight, a from created from just HTML can have the
fields and values from it extracted and processed by a php script? There
is no other php on my original page, just the form action sending the
form to ProcReg.php. I just want to use ProcReg.php to collect data from
an HTML form, check for blank fiels and valid data, then send it to
another HTML page. I think I have the code for blank field checking and
valid data checking, but, I don't quite know how to send the form back to
another fresh HTML page where a user can make edits if needed.

Regards,
C.B.
Ah the plot thickens . . . .

lol!

So what you want to do is retrieve the data from a form and populate
another form ?

Yes, that's correct.

If you want to pass a value into an html form element, you just need to
set its 'value' when you output the form.

From your original example, you have a field called Address1
if we want to send that out to a screen containing a form that the user
can edit we just need to send:
// inside the form construction
echo "<input type='text' name='Address1'
Value='".$_REQUEST('Address1')."'>";

Will this code populate a new form simply with data related to a field, or
will it actually create the field too?

note the string is in two parts with $_REQUEST('Address1') concatenated in
the middle using the dot string operator.

Where things can get a bit tricky is if you have a series of controls -
typically radio buttons or checkboxes with the same name but different
values, here the returned value is another array that has to be examined,
hence my suggestion to examine the incoming data with var_dump() while
debugging.

That is something I may have to look into as I have a couple of Yes/No radio
buttons.

The above example assumes that you know the name of the field, or you
could simply use $key and $value pairs as in your original posting inside
a loop.

OK thanks for your help.

Regards,
C.B.
