Re: calculations based on checkbox value

<?php $ad = ereg_replace ("\"", "&q&", $ad); # prevents an error when sending $ad through an HTML form $ad = ereg_replace ("'", "&a&", $ad); # prevents a mysql error $ad = ereg_replace ("%", "&p&", $ad); #prevents a mysql error $ad = ereg_replace ("\\\\", "&bs&", $ad); #prevents a mysql error # splits the ad into an array called $words $words = split(" ", $ad); # counts the number of expressions in the array $num = count($words); # variable used to check how many of the expressions are really spaces $count2 = 0; for($i = 0; $i < $num; $i++){ # determines if any variables are empty and if they are $count goes up one to determine how many spaces there are in the expressions if ($words[$count2] == "" ){ $count = $count + 1; } $count2 = $count2 + 1; } $num = $num - $count; #gets the new number of words $price = 5.00; if ($num > 10) { # if the users ad has more than 10 words in it than $quarters = the extra words times .20 $subtractor = $num - 10; $quarters = $subtractor * .20; } $subtotal = $price + $quarters; # price plus the number of words over 10 $total = $papers * $subtotal; # new price multiplied by number of papers $total = $total * $weeks; # new new price multiplied by number of weeks $total = sprintf ("%01.2f", $total); ?> Here is part of my function thus far, and the output is a simple $$ based on the number of words, I just need to add an IF statement to determine whether or not I will need to subtract a certain amount if a checkbox is checked. I am assuming that the IF statement would be something like... IF $variable = 1; { $variable - $total = $total2 ) Else do the rest of the code... I am still a newbie to php so any help would be great.
