Arrays

[Herman Wiid]

I have a menu, where a user picks a drink and then I want to use that price of the drink to do calculations. Help?

Store the price of the drink in a variable? I'm not sure how else you would do something like this. I would honestly consider going over the basics of PHP again. http://hudzilla.org is an amazing resource.

it can be in an array,

maybe you can put something like this on your form:

 

<input type="checkbox" name="pepsi" value="1.00" />Pepsi<br />

<input type="checkbox" name="coke" value="1.25" />Coke<br />

<input type="checkbox" name="sprite" value="1.50" />Sprite

 

then on the php that processes it just do something like this:

 

<?php

$soda['pepsi'] = $_POST['pepsi'];
$soda['coke'] = $_POST['coke'];
$soda['sprite'] = $_POST['sprite'];

foreach($soda as $name => $value){
echo "You purchase a $name for \$$value<br />\n";
}

// if you want to add them....

echo "Your total price is ". array_sum($soda);

?>
