Function and If Statement Problem

ryanhami

Hello,

I am having a problem with a function that I have made. Below you can see it.

function routedemand ($price, $distance, $averageprice) {

if (($price/105*100) < $averageprice) {

$routedemand = 80;

return $routedemand;

} elseif (($price/110*100) < $averageprice) {

$routedemand = 85;

return $routedemand;

} elseif (($price/120*100) < $averageprice) {

$routedemand = 90;

return $routedemand;

} elseif (($price/125*100) < $averageprice) {

$routedemand = 95;

return $routedemand;

} elseif (($price/130*100) < $averageprice) {

$routedemand = 100;

return $routedemand;

} elseif (($price/95*100) > $averageprice) {

$routedemand = 70;

return $routedemand;

} elseif (($price/70*100) > $averageprice) {

$routedemand = 60;

return $routedemand;

} elseif (($price/65*100) > $averageprice) {

$routedemand = 50;

return $routedemand;

}

}

I am wondering first if it is actually possible to do the division and multiplying in the if statements and whether this does actually work. Because any $price I use always outputs the $routedemand as 80.

Any help would be much appreciated.

Thanks,

Ryan

well, first off you have a lot of redundancy going on. You might want to consider looping through and incrementing your values by 5

otherwise, during your multiplication you need to encapsulate.


if (($price / (105*100)) < $averageprice) { 

$routedemand = 80; 

return $routedemand; 

}

Thanks, however it does not seem to work still. Its still giving me the 80.

can you display the query you're trying to execute?

ie: $prices/$averageprice...

Also, where does $distance come into play?

What I am trying to do is get the $routedemand to be inserted into a mysql database.

The price comes from a form that is submitted and then it uses the average price to work the $routedemand out.

The averageprice comes from -

function averageprice ($price, $distance) {

$averageprice = $distance/5;

return $averageprice;

}

Lets say the $distance = 10,000;

So the $averageprice = 2,000;

If I submit a $price of 1,000, the $routedemand should come back as 100;

But it comes back as 80.

Thanks.
