Hi I’m having a problem that i am curious if it is possible with repeater field. please see illustration below. Basically my maximum item should be 6 items so

if i have input only 2 items the output should be:

[1] [2]

then if i have 3 only:

[1] [3]
[2]

if i have 4 only:

[1] [3]
[2] [4]

if 5 only:

[1] [4]
[2] [5]
[3]

and finally if i have 6 items which is the maximum, this should display:

[1] [4]
[2] [5]
[3] [6]

any help for them to display inside table with 2 columns? Please help me. thank you

You’re not going to be able to do this without some extremely complex coding.

Is there a reason that you’re using a table?

If a table is the only way you can do this then I would suggest putting each row of the repeater into html and then output that html in the order you want based on the number of rows.

$row_html = array();
while(have_rows('repeater')) {
  the_row();
  $index = get_row_index();
  $row_html[$index] = '<div>';
  $row_html[$index] .= get_sub_field('my_sub_field');
  $row_html[$index] .= '</div>';
}

You’ll still need some creative logic, but at least you won’t be trying to do it inside of the loop.

hi I’m wondering why code won’t work when I put else if? I’m planning to do it manually since it will only have maximum of 6 items

<?php $row_html = array();
 while(have_rows('repeater')) {
  the_row();
  $index = get_row_index();
  $row_html[$index] = '<div>';
  $row_html[$index] .= get_sub_field('repeater_sub');
  $row_html[$index] .= '</div>';
} ?>
<?php if (($row_html[$index])<=2) {
  echo 'test 2 items';
} else if (($row_html[$index])<=3) {
  echo 'test 3 items';
} else {
  echo 'Test';
} ?> 

please help. Thank you

Your if/else should look something like this

if (count($row_html) <= 2) {
  echo 'test 2 items';
} elseif (count($row_html) <= 3) {
  echo 'test 3 items';
} else {
  echo 'test';
}

you could make that simpler to type and read by doing

$count = count($row_html);
if ($count <= 2) {
  echo 'test 2 items';
} elseif ($count <= 3) {
  echo 'test 3 items';
} else {
  echo 'test';
}

you can simplify it more by using a switch statement which is easier to read when you have a lot of conditions than an if/elseif statement

switch (count($row_html) {
  case 1:
    echo '1 block';
    break;
  case 2:
    echo '2 blocks';
    break;
  case 3:
    echo '3 blocks';
    break;
  case 4:
    echo '4 blocks';
    break;
  case 5:
    echo '5 blocks';
    break;
  case 6:
    echo '6 blocks';
    break;
}

Hi thank you. but I’m wondering, even if I have more than 2 items , the output is still 2? even though I set a condition if there are 3 items but still at your example it echoed 2. also switch case seem not working for count function. I don’t know but I really tried count function for repeater but doesn’t show correct output. it always shows “1” even if i have multiple rows. please help me. More important is that it counts the repeater rows then get each item that will put manually. thanks

Hi Finally figured it out. I realized that mistyped repeater sub name. Anyway since it’s only 6 items, for now this is my solution. Thank you for helping to start!

<?php
 
 $row_html = array();
 while(have_rows('repeater')) {
  the_row();
  $index = get_row_index();
  $row_html[$index] = get_sub_field('repeatersub');
 }
 
 $count = count($row_html);
 
 if($count==1) {
  echo 'Im 1';
 }
 
 elseif($count==2){
  echo 'Im 2';
  echo $row_html[2];
  echo $row_html[1];
 }
 
 elseif($count==3){
  echo 'Im 3';
  echo $row_html[3];
  echo $row_html[1];
  echo $row_html[2];
 }
 
 elseif($count==4){
  echo 'Im 4';
  echo $row_html[4];
  echo $row_html[1];
  echo $row_html[2];
  echo $row_html[3];
 }
 
 elseif($count==5){
  echo 'Im 5';
  echo $row_html[2];
  echo $row_html[4];
  echo $row_html[3];
  echo $row_html[5];
  echo $row_html[1];
 }
 
 elseif($count==6){
  echo 'Im 6';
  echo $row_html[5];
  echo $row_html[6];
  echo $row_html[3];
  echo $row_html[2];
  echo $row_html[1];
  echo $row_html[4];
 }
 
 else {
  echo 'None';
 }
 
 ?>
