I want to display a certain callout on my site (it is an ACF image field), but I want it only to display during a certain time.
I am looking to use a Date Time Picker field for the start date/time and a Date Time Picker for the end date/time. However, how would I check to see if the current date/time is within the start and end time frame?
this is only one possibility
// current unix time stamp
$now = time();
// get field with no formatting
// this will return date time as stored in the db
// to that there isn't any problem with the date format
// when calling strtotime()
$start = strtotime(get_field('start_date_time', false, false));
// same for end
$end = strtotime(get_field('end_date_time', false, false));
if ($start <= $now && $now <= $end) {
// in the middle, do something.
}
Awesome.
And since I am actually using this in conjunction with a javascript function, would the below work?
<script>
var nowTime = <?php time(); ?>;
var startTime = <?php strtotime(get_field('start_date_time', false, false)); ?>;
var endTime = <?php strtotime(get_field('end_date_time', false, false)); ?>;
if (startTime <= nowTime && nowTime <= endTime) {
//do something
}
</script>
Also, I am assuming the PHP time(); function and the Date Time Picker both use the server’s time zone, correct?
You would need to echo the values to get them into the JS
<script>
var nowTime = <?php echo time(); ?>;
var startTime = <?php echo strtotime(get_field('start_date_time', false, false)); ?>;
var endTime = <?php echo strtotime(get_field('end_date_time', false, false)); ?>;
if (startTime <= nowTime && nowTime <= endTime) {
//do something
}
</script>
Oh yeah, of course. Missed that.
Thanks!
And I am assuming the time() function uses the server’s time zone, correct? So the Date Time Picker date/time selected should use that same time zone as the server, correct?
Yes it does, but I don’t know how ACF gets the current time, I don’t really think it needs to get the time because you use fields to set times. There is a function in wp to get the time https://codex.wordpress.org/Function_Reference/current_time, but in the end it’s just a complicated way to call time().
