I’m trying to do a count of the total number of post objects selected so that if it’s 1,2 or 3 it shows them in a certain method;
e.g. 1 = full width, 2 = half width etc.
My code is;
<?php
if( have_rows('featured_developments') ):
$count = 0;
?>
<?php while( have_rows('featured_developments') ): the_row(); ?>
<?php
$post_id = get_sub_field('development', false, false);
$rows = get_sub_field('development');
if( $post_id ):
$count++;
?>
<?php if ($count == 1) { ?>
1
<?php } else if ($count == 2 ) { ?>
2
<?php } else { ?>
3
<?php } ?>
<?php endif; ?>
<?php endwhile; ?>
<?php endif; ?>
<?php wp_reset_query(); ?>
However the just outputs 1 2 for some reason, despite only 2 being selected in the back-end.
$count = count(get_field('featured_developments'));
// use this number for the count of rows
if (have_rows('featured_developments')) {
// etc....
}
Hi John,
Thanks for getting back to me, I tried that and didn’t work the “echo $count = 2” was correct so I used this code;
<?php
$count = count( get_sub_field('featured_developments') );
echo '<strong>The total is '. $count . '</strong></br><br>';
if( have_rows('featured_developments') == 1 ) {
?>
<?php while( have_rows('featured_developments') ): the_row(); ?>
<?php
$post_id = get_sub_field('development', false, false);
?>
<div class="lg-col-12"></div>
<?php $count++; ?>
<?php endwhile; ?>
<?php
} elseif( have_rows('featured_developments') == 2 ) {
echo '2';
?>
<?php while( have_rows('featured_developments') ): the_row(); ?>
<?php
$post_id = get_sub_field('development', false, false);
?>
<div class="lg-col-6 md-col-6"></div>
<?php $count++; ?>
<?php endwhile; ?>
<?php
} else{
?>
<?php while( have_rows('featured_developments') ): the_row(); ?>
<?php
$post_id = get_sub_field('development', false, false);
?>
<div class="lg-col-4 md-col-4"></div>
<?php $count++; ?>
<?php endwhile; ?>
<?php
}
?>
<?php wp_reset_query(); ?>
It outputted “lg-col-12”, when it should’ve outputted “lg-col-6”
In your case there is not a reason to increment count $count++ as $count already has the total number of rows in your repeater.
I removed that thanks, but still no change;
<?php
$count = count( get_sub_field('featured_developments') );
echo '<strong>The total is '. $count . '</strong></br><br>';
if( have_rows('featured_developments') == 1 ) {
?>
<?php while( have_rows('featured_developments') ): the_row(); ?>
<?php
$post_id = get_sub_field('development', false, false);
?>
<div class="lg-col-12">
</div>
<?php endwhile; ?>
<?php
} elseif( have_rows('featured_developments') == 2 ) {
?>
<?php while( have_rows('featured_developments') ): the_row(); ?>
<?php
$post_id = get_sub_field('development', false, false);
?>
<div class="lg-col-6 md-col-6">
</div>
<?php endwhile; ?>
<?php
} else{
?>
<?php while( have_rows('featured_developments') ): the_row(); ?>
<?php
$post_id = get_sub_field('development', false, false);
?>
<div class="lg-col-4 md-col-4">
</div>
<?php endwhile; ?>
<?php
}
?>
<?php wp_reset_query(); ?>
$count = count(get_field('featured_developments'));
if (have_rows('featured_developments')) {
$class = 'lg-col-4 md-col-4';
if ($count == 1) {
$class = 'lg-col-12';
}
if ($count == 2) {
$class = 'lg-col-6 md-col-6';
}
while (have_rows('featured_developments')) {
the_row();
?><div class="<?php echo $class; ?>"><?php echo $class; ?></div><?php
}
}
Perfect thanks John, I can see now where I was going wrong 🙂
