I have a function that checks if today's date falls in between multiple date intervals in an array. The only thing I need is for this function to return the $location value in the checkRange function.
function promoDates(){
$current = strtotime("now");
// Array gives a place, start date, and end date
$intervals = array(
//The $current start time falls between the dates in washington array
array('washington', strtotime("2015-01-08 00:00"), strtotime("2015-01-30 00:00")),
array('california', strtotime("2015-06-02 00:00"), strtotime("2015-06-17 00:00")),
array('texas', strtotime("2015-02-12 00:00"), strtotime("2015-02-27 00:00")),
array('ney-york', strtotime("2015-05-12 00:00"), strtotime("2015-05-26 00:00")),
array('tennessee', strtotime("2015-10-29 00:00"), strtotime("2015-11-12 00:00")),
array('utah', strtotime("2015-09-15 00:00"), strtotime("2015-09-30 00:00")),
array('florida', strtotime("2015-11-12 00:01"), strtotime("2015-11-27 00:00"))
);
function checkRange($location, $startDate, $endDate, $currentDate){
if ($currentDate >= $startDate && $currentDate <= $endDate){
// Successfully echos 'washington' to page
echo $location."<br>";
return $location;
}
}
for ($i = 0; $i <= 6; $i++){
checkRange($intervals[$i][0], $intervals[$i][1], $intervals[$i][2], $current);
}
//This does not echo the location from the checkRange function
echo checkRange();
}
I just need help getting the promoDates function to return what the checkRange function is echoing. Is there a way I can set a variable inside the checkRange function and return it in the promoDates function?
Well you arent passing in any arguments to the checkRange()
function... I would also change the signature of the checkRange function to take an array for interval:
function promoDates() {
$current = strtotime("now");
// Array gives a place, start date, and end date
$intervals = array(
//The $current start time falls between the dates in washington array
array('washington', strtotime("2015-01-08 00:00"), strtotime("2015-01-30 00:00")),
array('california', strtotime("2015-06-02 00:00"), strtotime("2015-06-17 00:00")),
array('texas', strtotime("2015-02-12 00:00"), strtotime("2015-02-27 00:00")),
array('ney-york', strtotime("2015-05-12 00:00"), strtotime("2015-05-26 00:00")),
array('tennessee', strtotime("2015-10-29 00:00"), strtotime("2015-11-12 00:00")),
array('utah', strtotime("2015-09-15 00:00"), strtotime("2015-09-30 00:00")),
array('florida', strtotime("2015-11-12 00:01"), strtotime("2015-11-27 00:00"))
);
// we will use this like a filter
function checkRange($currentDate, $promo) {
list($location, $startDate, $endDate) = $promo;
// return true or false
return (($currentDate >= $startDate) && ($currentDate <= $endDate));
}
// loop over the intervals until we find a match then return it:
foreach($intervals as $promoData) {
if (checkRange($current, $promoData) === true) {
return $promoData[0];
}
}
// return null if we do not find any
return null;
}
And usage would look like:
echo promoDates();
edit: I actually just fixed it by following @prodigitalson advice and checking if each loop iteration is true or false, then returning the value where it is true.
function checkRange($startDate, $endDate, $currentDate, $loc){
if ($currentDate >= $startDate && $currentDate <= $endDate){
return true;
} else{
return null;
}
}
for ($i = 0; $i <= 6; $i++){
if(checkRange($intervals[$i][1], $intervals[$i][2], $current, $intervals[$i][0]) == true){
return $intervals[$i][0];
}
}
and removing the echo checkRange(); at the bottom.
