Help with if else

[stevenjweir]

Hi guys,

 

I'm still learning PHP so bare with me please. I've written a script to change the displayed price of a product based on the currency set in a cookie.

 

The script is:

<?php

if ($_COOKIE["currency"] == dollar) {echo "$";} /* if the cookie is set to Dollar, show a '$' */
else if ($_COOKIE["currency"] == euro) {echo "€";} /* or if the cookie is set to Euro, show a '€' */
else { echo "£";} /* or if the cookie isn't set to Dollar or Euro, show a '£' */

printf ('%02.2f', (($row_getdets['price']) * $row_prices['[$_COOKIE["currency"]']) ); /* Show Price multiplied by the chosen currency rate set by the cookie, set to 2 decimals. */

?> 

 

So basically I just need it to show the currency symbol, ie: £, $ or € and then show the price. The price part works, the bit that doesn't is the if else part. Any help would be really appreciated.

<?php

if ($_COOKIE["currency"] == 'dollar') {echo "$";} /* if the cookie is set to Dollar, show a '$' */
else if ($_COOKIE["currency"] == 'euro') {echo "€";} /* or if the cookie is set to Euro, show a '€' */
else { echo "£";} /* or if the cookie isn't set to Dollar or Euro, show a '£' */

printf ('%02.2f', (($row_getdets['price']) * $row_prices['[$_COOKIE["currency"]']) ); /* Show Price multiplied by the chosen currency rate set by the cookie, set to 2 decimals. */

?> 

 

You missed the quotation marks around the $_COOKIE values. ie 'dollar', 'euro'.

micmania1, thank you. Sorted it.

 

Also I just noticed the price bit doesn't actually work.

 

The line:

 

printf ('%02.2f', (($row_getdets['price']) * $row_prices['dollar']) );

 

where it says dollar, I need it to grab $_COOKIE["currency"] and replace the dollar.How do I include the $_COOKIE data within that ['dollar'] box?

You need to look at the problem a bit differently then.

 

// Guessed rates
$currency = array(
'gbp' => array('symbol' => '£', 'rate' => '1'),
'dollar' => array('symbol' => '$', 'rate' => '1.4'),
'euro' => array('symbol' => '€', 'rate' => '1.1')
);

// Store the currency in the cookie (ie gbp, dollar etc)
if (array_key_exists($_COOKIE['currency'], $currency)) {
$symbol = $currency[$_COOKIE['currency']]['symbol'];
$rate = $currency[$_COOKIE['currency']]['rate'];

// Work out price in new currency
$price = ($row_getdets['price'] * $rate);

// Display price in currency
echo $symbol.$rate;
} else {
// Cookie has invalid vlue
// currency does not exist
die("Invalid currency");
}
