Help converting a short ASP script to PHP

SadGeezer

Hi,

I've tried fixing this myself, but no joy 🙁

All I can think is to offer the problem to you guys and hope that someone can crack it. The first to do so wins a sadgeezer t-shirt of baseball cap - Hey, don't scoff, they're quite rare! 😃

Can anyone help me with a simple php script which would do the same?

The script is called from the following form tag:

 <form action="http://www.affinity-intranet.org.uk/test.asp" method="post"> 
<input type="hidden" name="header-0-28" value="http://www.sadgeezer.com/babylon5/twerp.htm">          

<input type="hidden" name="header-29-38" value="http://www.sadgeezer.com/babylon5/sad.htm">               

<input type="hidden" name="header-39-99" value="http://www.sadgeezer.com/babylon5/manic.htm">

There are 15 questions. Each question is multiple choice and has three different options (radio butttons) eg.:

<input type="radio" name="1" value="1">

Note: Each option has the same 'name' and value is either 1, 2 or 3 depending on the validity of the answer. The 'name' changes for each question number so an example of one of the options for question 14 would be:

<input type="radio" name="14" value="1">

At the end of the form there is a 'Rate Me' and a 'Start Again' button:

<input type="submit" value="Rate Me">
<input type="reset" value="Start Again">
</form>

Once the rate me button is pressed, the script below calculates the totals of each question (ie. it adds up all the 1's 2's and 3's from all the questions and sends the answer back to the form. Sounds simple huh? 🙁

ASP Script called 'test.asp'

<% result=0
for each Item in Request.Form
if isNumeric(Item) then
result=result+Request.Form(Item)
end if
next 
if result<=28 then
redirect=request.form("header-15-28") 
elseif result>28 and result<39 then
redirect=request.form("header-29-38") 
else
redirect=request.form("header-39-45") 
end if
response.redirect(Server.MapPath(redirect))
%>

Please would someone show me a simple php script that could replace the 'test.asp' script and allow me to leave the html tags in my files.

Reason I need the script? - I run the site sadgeezer.com with lots of cult TV sci fi resources including a large number of Purity Tests. Now that I'm all PHP (thank goodness!) my host doesn't have ASP. therefore the Tests don't work and my members and visitors are annoyed 🙁

An example if the Test is at:
http://www.sadgeezer.com/html/Sections+index-req-viewarticle-artid-58-page-1.html

But of course, it doesn't work now.

Any help would be hugely appreciated - I'll even send the first person to crack the problem a sadgeezer.com t-shirts or baseball cap 🙂

I don't know ASP or anything other than PHP (which I still don't know well 😃), but I'm going to give this a shot. You may need to make some minor changes, but I'll try to include those.

Quick notes: this script will not check to see if everything was filled out, try doing that with JavaScript. Notice that the header() function is used. header() can only be used in one of two ways: before any output is created by the page/script, or with output buffering. See http://www.php.net/header and http://www.php.net/ob_start for more info.

ALSO you have a small discrepancy in your code. On your form, one of the names is 0-28 but in your ASP code you have 15-28 and no value for 0. I will go by your ASP.

Contents of whatever page:

<form action="http://www.affinity-intranet.org.uk/test.php" method="post">
<input type="hidden" name="header-15-28" value="http://www.sadgeezer.com/babylon5/twerp.htm">
<input type="hidden" name="header-29-38" value="http://www.sadgeezer.com/babylon5/sad.htm">
<input type="hidden" name="header-39-99" value="http://www.sadgeezer.com/babylon5/manic.htm">

<input type="radio" name="1" value="1"> (etc etc)

<input type="submit" value="Rate Me"> 
<input type="reset" value="Start Again"> 
</form>

Contents of test.php:

<?php

global $total; // Make sure we can use total after our foreach loop
$total = 0; // Sort of a formality, but good form nonetheless


// $_POST is the array of submitted data in PHP
foreach($_POST as $name => $value) {

if(is_int($name))
$total += $value; // Add value to total

}

if($total >= 39) {
header("Location: " . $_POST['header-39-99']); // Redirect to pre-defined page
exit; // Stop executing code
}
elseif($total >= 29) {
header("Location: " . $_POST['header-29-38']); // See above
exit;
}
else
{
header("Location: " . $_POST['header-15-38']); // See above
exit;
}

?>

That should do it. If you are wondering what any of those functions do, look them up like this: php.net/function

I'll run this through right now to check for errors but it should work as-is.

(Edit: forgot some line breaks 😃)

Thanks man!

Very cool coding 🙂

Works perfectly! I had a little trouble with the setting up (hense the lengthy time in replying 🙂 )

I fixed my problem by checking out the links you gave me - helped me learn a bit more about PHP too.

Thanks again dude!

You can see the test working at:
http://www.sadgeezer.com/html/Sections+index-req-viewarticle-artid-31-page-1.html

In fact, I came up with a way of being able to change all my tests without having to write new scripts for each. I changed your code from:

header("Location: " . $_POST['header-39-99']); // Redirect to pre-defined page 
exit; // Stop executing code 
} 
elseif($total >= 29) { 
header("Location: " . $_POST['header-29-38']); // See above 
exit; 
} 
else 
{ 
header("Location: " . $_POST['header-15-38']); // See above 
exit;

header("Location: " . $_POST['header-manic']); // Redirect to pre-defined page 
exit; // Stop executing code 
} 
elseif($total >= 29) { 
header("Location: " . $_POST['header-sad']); // See above 
exit; 
} 
else 
{ 
header("Location: " . $_POST['header-twerp']); // See above 
exit;

All I had to do was change the html form tag to the same. Now I can use the same script for calculating the outputs in all my tests even if the scoring criteria changes!
