Hi,

So the normal sort on repeater field is oldest entered goes to top – I want the reverse of this last repeater field entered goes to top.

I have my repeater code with array_multisort

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_header'];
}

/*
*  Use the $column_id array to sort the $repeater array
*/

array_multisort( $column_id, SORT_DEC, $repeater );

/*
*  Do stuff with the repeater... Note: has_sub_field loop will not use the "sorted" $repeater array
*/

		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>';
		}
}

So really the sort here sorts alpha according to the text strings, how would I do this sort by the date and order the repeater field was created.

hi, try if this works: (sort by date-field instead of header)

foreach( $repeater as $key => $row ) {
		$thedate = $row['your_date_field']; 
		$column_id[ $key ] = strtotime($thedate);
	}
array_multisort( $column_id, SORT_DESC, $repeater );
	foreach( $repeater  as $row ){

i assume date field is part of the repeater.
replace your_date_field with name of the date field. (part of my code)

Hi again,
Thanks for your help – actually I didn’t have a date field – but added one and used this

foreach( $repeater as $key => $row ) {
    
    $column_id[ $key ] = $row['date_added'];
}

/*
*  Use the $column_id array to sort the $repeater array
*/

array_multisort( $column_id, SORT_DESC, $repeater );
