confused newb...

drag0n

if I want to make this script:

<html>
<body>
<table border = 0 cellpadding = 3>
<tr>
  <td bgcolor = "#CCCCCC" align = center>Distance</td>
  <td bgcolor = "#CCCCCC" align = center>Cost</td>
</tr>
<? 
$distance = 50;
while ($distance <= 250 )
{
  echo "<tr>\n  <td align = right>$distance</td>\n";
  echo "  <td align = right>". $distance / 10 ."</td>\n</tr>\n";
  $distance += 50;
}
?>
</table>
</body>
</html>

Display the Cost side dynamically using the get function to get the type of shipping which will be passed through ther url. So say I want to divide the $distance by $ship, but $ship will have different prices depending on the type of shipment the user choose; overnight, 2nd day, ground. so the url would be something like:

http://yoursite.com/shipcost.php?ship=ground

and depending on that you can caluate the total cost for shipping. What I am confused about is I thought I would be able to use the IF and ELSE IF, but I got stuck there. I hope you can help me out, thanks! Below is a copy of what I imagine the form of the script sould be, but Im pretty sure im wrong!

<html>
<body>
<table border = 0 cellpadding = 3>
<tr>
  <td bgcolor = "#CCCCCC" align = center>Distance</td>
  <td bgcolor = "#CCCCCC" align = center>Cost</td>
</tr>
<? 
$ship = $GET_['ship'];

if( $ship == ground )

{

$ship == 15;

}

elseif( $ship == 2ndDAY )

{

$ship == 10;

}

elseif( $ship == overnite)

{

$ship == 5;

$distance = 50;
while ($distance <= 250 )
{
  echo "<tr>\n  <td align = right>$distance</td>\n";
  echo "  <td align = right>". $distance / $ship ."</td>\n</tr>\n";
  $distance += 50;
}
?>
</table>
</body>
</html>

Thanks in advanced! =)

Who not through in two more variables and use them accordingly?

$distance = 50;

$distance2 = ($distance/10);

$distance3 = ($distance + 50);

Or if you are adding 50 to your distance after dividing it just to get it back to 50, then leave out $distance3 and just call distance again.

Dunno if this is what your looking for, but I would use it.

Could you explain better, like maybe redo the script with hwta you have in mind?

Kudose

<?
$distance = 50;
$distance2 = ($distance/10);

while ($distance <= 250 )
{
echo "<tr>\n <td align = right>$distance</td>\n";
echo " <td align = right>". $distance2."</td>\n</tr>\n";

}
?>

well i fixed everything to this:

<html>
<body>
<table border = 0 cellpadding = 3>
<tr>
  <td bgcolor = "#CCCCCC" align = center>Distance</td>
  <td bgcolor = "#CCCCCC" align = center>Cost</td>
</tr>
<? 
$ship = $GET_['ship'];

if( $ship == "ground" )

{

$ship = 15;

}

elseif( $ship == "2ndDAY" )

{

$ship = 10;

}

elseif( $ship == "overnite")

{

$ship = 5;
}
else
{
echo "...";
exit;

}

$distance = 50;
while ($distance <= 250 )
{
  echo "<tr>\n  <td align = right>$distance</td>\n";
  echo "  <td align = right>". $distance / $ship ."</td>\n</tr>\n";
  $distance += 50;
}
?>
</table>
</body>
</html>

Now everything shows up with no errors, but the cost side of it is blank! Can somnebody please help me out =)

Kudose

Try ('$distance'/'$ship')

drag0n

<html>
<body>
<table border = 0 cellpadding = 3>
<tr>
  <td bgcolor = "#CCCCCC" align = center>Distance</td>
  <td bgcolor = "#CCCCCC" align = center>Cost</td>
</tr>
<? 
$ship = $GET_['ship'];

if( $ship == "ground" )

{

$ship = 15;

}

elseif( $ship == "2ndDAY" )

{

$ship = 10;

}

elseif( $ship == "overnite")

{

$ship = 5;
}
else
{
echo "...";
exit;

}

$distance = 50;
while ($distance <= 250 )
{
  echo "<tr>\n  <td align = right>$distance</td>\n";
  echo "  <td align = right>".('$distance'/'$ship') ."</td>\n</tr>\n";
  $distance += 50;
}
?>
</table>
</body>
</html>

I did that and it still doesnt work...
I used the url
http://localhost/ship.php?ship=ground
And it doesnt work.. Whats wrong with it? Thanks in advanced!

sijis

why the space in:

echo "  <td align = right>". $distance / $ship ."</td>\n</tr>\n";

put them together so php knows you are trying to compute the values.

This should work.

echo "  <td align = right>". $distance/$ship ."</td>\n</tr>\n";

you can optionally add the () between them:
($distance/$ship)

also...

this line:

$ship = $GET_['ship'];

should probably read like this:

$ship = $_GET['ship'];

drag0n

thankS~! so it wasnt a problem with the form of the code, but with the

$ship = $_GET['ship']

Thanks for pointing that out!
Now, i have another problem.. how to I round the cost to the nearest cent or dollar? Do I put like (integer) to it? Sorry Im a newbie, so I have no idea about PHP =)
Thanks in advanced!

drag0n

do I set the variable type or something?
