Hi,
I am trying to reverse sort the repeater rows – currently I can display my repeater rows using
function trs_testimonial_loop () {
//My ACF Fields for reference
//testimonials - field group
//testimonial - sub-field
//testimonial_header - sub-field
// check if the repeater field has rows of data
if( have_rows('testimonials') ):
// loop through the rows of data
while ( have_rows('testimonials') ) : the_row();
// display a sub field value
echo '<article><div class="entry-content testimonial">';
echo '<p>' . get_sub_field('testimonial') . '</p>';
echo '<h2>' . get_sub_field('testimonial_header') . '</h2>';
echo '</div></article>';
endwhile;
else :
// no rows found
endif;
}
But if I try to use the code example for sorting like this…
function trs_testimonial_loop_sort() {
//My ACF Fields for reference
//testimonials - field group
//testimonial - sub-field
//testimonial_header - sub-field
$repeater = get_field('testimonials');
/*
* Obtain a list of columns
* - $column_id will look something like this:
Array
(
[0] => 3
[1] => 2
[2] => 4
[3] => 1
)
*/
foreach( $repeater as $key => $row ) {
$column_id[ $key ] = $row['testimonial'];
}
/*
* Use the $column_id array to sort the $repeater array
*/
array_multisort( $column_id, SORT_ASC, $repeater );
/*
* Do stuff with the repeater... Note: has_sub_field loop will not use the "sorted" $repeater array
*/
foreach( $repeater as $row ) {
// display a sub field value
echo '<article><div class="entry-content testimonial">';
echo '<p>' . get_sub_field('testimonial') . '</p>';
echo '<h2>' . get_sub_field('testimonial_header') . '</h2>';
echo '</div></article>';
}
}
I get no output at all – I know I am missing something fundamental – any advice
would this work? :
foreach( $repeater as $row ) {
$testimonial_p = $row['testimonial'];
$testimonial_h2 = $row['testimonial_header'];
echo '<article><div class="entry-content testimonial">';
echo '<p>' . $testimonial_p . '</p>';
echo '<h2>' . $testimonial_h2 . '</h2>';
echo '</div></article>';
}
thank you very much that now outputs and sorts – I do have a follow up question about sorting by date entered – I’ll post a new thread.
