As seen on UPS...

[LordShryku]

UPS has a tracking site that was done in CGI.
http://www.ups.com/tracking/tracking.html
When you click on the Enter More Numbers button, it looks like it does some server side scripting along with the get method in the form to open up 5 more slots to enter information while bringing the old input to the new page. I was wondering if anyone knew an easy way to do this in PHP? I'd like to be able to add something like that to a couple of my big forms to try to bring them down to size.

Thanks!

i just posted a corrected version... here it is - works fine for me:

<?php
if (isset($track)) {
    print "data submitted<BR><BR>";

foreach ($InquiryNumber as $key => $value) {
    print "$key: $value <BR>";
}

}

else {

if (!$startVal) {
    $startVal = 0;
}

if (isset($moreOptions)) {
     $startVal += 5;
}
print "<FORM ACTION=\"$PHP_SELF\" METHOD=\"POST\">";

for ($i = 1; $i <= $startVal+5; $i++) {
    print "$i" . ". <INPUT TYPE=\"TEXT\" NAME=\"InquiryNumber[" ."$i" . "]\" VALUE=\"$InquiryNumber[$i]\"><BR>";
}

print "
<INPUT TYPE=\"hidden\" NAME=\"startVal\" VALUE=\"$startVal\">
<INPUT TYPE=\"SUBMIT\" NAME=\"moreOptions\" VALUE=\"More Options\"><BR>
<INPUT TYPE=\"SUBMIT\" NAME=\"track\" VALUE=\"Track\">

</FORM>";
}
?>

i still have one problem here i ran into a bunch of times already - why cant i pass a value of a variable thet is "0"?

$startVal=0;

print "<INPUT ... VALUE=\"$startVal\">";

results in an http output like this:

<INPUT ... VALUE="">

instead of this:

<INPUT ... VALUE="0">

why? is it NULL and not 0? what can i do about it?

Damn, you guys are good!

Thanks a bunch!

one more thing:

put this line right after the

for (...) {

line:

$InquiryNumber[$i] = htmlspecialchars(stripslashes($InquiryNumber[$i]));

depending on what your input is this might be nexessary to keep the stuff formatted in the right way...

Here's yet another question(just tell me when I'm a pain in the a$$). One of my original forms passed the info to a confirmation page using the GET method. How could I change the first if statement to work with this setup?

[LordShryku]

Here is an example. This was all originally done in html. I'm just wondering if there's a way to plug this code into the original HTML file....

Okay, I figured all of this out, but one question remains. Is there a way to disable the More Options button here after it has hit a certain number, like 10?
