The statement returns false if it shouldn't
The following statement returns false
for whatever reason:
$coin = isset($_GET['market']) ? $_GET['market'] : 'BTC_USD';
echo $coin;
if($this->model->coins($coin) == false):
$coin = 'BTC_USD';
else:
$coin = $_GET['market'];
endif;
Model:
public function coins($coin)
{
$coins = array("BTC_USD","BTC_GBP","LTC_USD","LTC_GBP","BTC_LTC","USD_GBP");
if (!in_array($coin, $coins))
{
return false;
}
}
If i echo
$coin
before the operator if
returns the correct coin, but after the operator it if
returns false
. I know this is a simple solution, it just completely bypasses me. :(
The method coins()
never returns true
. When it doesn't return false
, it returns undefined
because there is no alternative operator return
. Since you are performing a free comparison to the caller undefined == false
. Change the method to:
public function coins($coin)
{
$coins = array("BTC_USD","BTC_GBP","LTC_USD","LTC_GBP","BTC_LTC","USD_GBP");
return in_array($coin, $coins));
}
