[HELP] Making a simple multiply script - not so simple :(!

colleyboy · November 29, 2010

Hi pplz...

I am designing a carpet website for a friend but am having a problem.

http://www.ircdirect.co.uk/FTPServers/supremecarpets/carpets.php?id=1

On this page ^^^ I want to make a simple script so that a person can enter a number, press calculate and it calculates the cost of the flooring.

I.E: This flooring is: £17.88 per metre (its stored in the database under price).

maybe something like:


<?PHP 

echo "<FORM><input type=input></FORM>*.$row['imageloc'].";
echo"<INPUT TYPE=SUBMIT></FORM";

?>

TBH I dont know, any help is very much appreciated as google couldnt help

Many Thanks,

Ian

If you are having difficulty with this it may behoove you to pick up a beginners MySQL/PHP book. Alls you are doing is taking a POST value, doing a query against the database, multiplying the two values, and displaying the result to the user.

colleyboy · November 29, 2010

Well so far I have done the following:

$a=$row['price'];
$b=area;
$total=$a*$b;

echo "<FORM action=carpets.php?id=".$row['id']." method=post />";
echo "<input type=text name=area WIDTH=30 />";
echo "<input type=submit value=Calculate values />";
echo "</FORM />";

but for some reason when the page refreshes it doesn't come back with any value... still "0" always at the moment.

Any help?

That cannot be the entire code because I don't see a query...you should invest in a book.

Sorry, but negative critisism isnt helpful. I can only do my best. I came on here for help... not for people to write scripts for me, but to help me correct any mistakes. I am only human.

This is the script below:

<HEAD>

<?php

include ('dbconnect.php');
