Hi!
I’m having a little problem that I think should be solved easily with some kind of unique array or foreach function.
My code looks like this:
<? if( get_field('kontaktpersoner') ): ?>
<?php while( has_sub_field('kontaktpersoner') ): ?>
<?php $arbetsgrupp = get_sub_field('arbetsgrupp'); ?>
<?php echo $arbetsgrupp; ?>
<?php endwhile; ?>
<?php endif; ?>
The $arbetsgrupp can be “Red”, “Green” and “Blue”.
My problem is that if there is more than one “Red” it’s displayed 2 times or more but I want all values to be uniqe. Just one output for each value.
Am I making any sence?
Instead of echoing Red, Red, Blue, Green, Blue I want it to be: Red, Blue, Green.
Hello Henric,
This is untested but this should do it:
<?php
if( get_field('kontaktpersoner') )
{
$arbetsgruppen = array();
while( has_sub_field('kontaktpersoner') )
{
$arbetsgrupp = get_sub_field('arbetsgrupp');
if(!in_array($arbetsgrupp,$arbetsgruppen))
{
array_push($arbetsgruppen,$arbetsgrupp);
}
}
foreach($arbetsgruppen as $arbetsgrupp)
{
echo $arbetsgrupp;
}
}
?>
