Thanks Johnathan, yes tested that and it outputs the list – now i’ll see if I can hook that in. Appreciated.
Hi @jonathan yes the actual text from the selections, so only if selected in the backend.
Wow you do know your stuff! – Many thanks that works perfectly, the only thing that i don’t grasp 100% is
$row_count--;
I do understand by its use we are moving from zero based index to get the last proper row.
You said earlier that:
$rows--; is short form of $rows = $rows-1;
So in the code that works, instead of using $row_count--; i tried $row_count-1;
but that outputs nothing, I was wondering for my own curiousity how to use arithmetic operator on the row count so for instance I could output the 2nd last one.
tried to this using
$rows = get_post_meta( 348, 'testimonials', false ); // get number of rows (8 but in a array)
$row_count = $rows[0]; //get row number out of array (8)
echo $row_count--; // because first row start with 0 not 1 subtract one from row number (8-1 =7)
//now you could use $row_count to get last row (7)
$lastrow = 'testimonials_'.$row_count.'_testimonial'; //you need to replace echo by a variable and use that
echo $lastrow;
What i get front end is
8testimonials_7_testimonial
okay result i get from
echo '<pre>';
print_r( $rows);
echo '</pre>';
is
Array
(
[0] => 8
)
Which is the 8 repeater rows current in the array.
how do i use $rows--; ?
and/or how would i always echo the last row after more rows where added?
ok thanks – so I can get a specific row output like so…
<?php
$rows = get_post_meta( 348, 'testimonials', false ); // get all the rows
$end_testimonial_content = get_post_meta( 348, 'testimonials_4_testimonial', true );// get the sub field value
$end_testimonial_header = get_post_meta( 348, 'testimonials_4_testimonial_header', true ); // get the sub field value
$last = '<blockquote>' . $end_testimonial_content . '</blockquote><p>' . $end_testimonial_header . '</p>';
echo $last;
?>
I also tried with end function but couldn’t get it to work, but as a fallback at least I have something on the page.
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 );
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.
