Flexible content inside a repeater field

I did not find on your site and on google, the case of a flexible content inside a repeater.

Unfortunately I can not recall correctly a flexible content that is filed inside a repeatable.

A normal field flexibile activates a great time with foolish examples.

flex_content = field type flex content
1° element on flex content = flex_content_first_element
sub field in to 1° element = flex_content_first_element_subfield
2° element on flex content = flex_content_second_element
sub field in to 2° element = flex_content_second_element_subfield

if( have_rows('flex_content') ){
     // loop through the rows of data
    while ( have_rows('flex_content') ){ the_row();
        if( get_row_layout() == 'flex_content_first_element' ){
              the_sub_field('flex_content_first_element_subfield');
         } 
        elseif( get_row_layout() == 'flex_content_second_element' ){ 
              the_sub_field('flex_content_second_element_subfield');
        }
     }

} else { }

so everything is right. But if the value “field type flex content” was not top level but it is contained by a field riptetitore.
What should I put in “have_rows (?)”

I tried several attempts but do not function.
So, you are the ultma beach ..

I hope you know tell me the right one variable for this to work.

Thank you!

You need to have nested loops for flex fields inside a repeater

if (have_rows('repeater_field')) {
  while (have_rows('repeater_field')) {
    the_row();
    if (have_rows('flex_content_field')) {
      while (have_rows('flex_content_field')) {
        $layout = get_row_layout();
        // and the rest of your flex field output
      } // end second while have rows
    } // end second if have rows
  } // end first while have rows
} // end first if have rows

for more information see the nested loop section of this page http://www.advancedcustomfields.com/resources/have_rows/

thanks, now I understand the concept of recall.
I had not thought because I usually use the foreach statement to retrieve reperater.

I looked back and saw that I forgot something important. My code above will create and infinite loop. Someday I should right a book on how to do it 😛

if (have_rows('repeater_field')) {
  while (have_rows('repeater_field')) {
    the_row();
    if (have_rows('flex_content_field')) {
      while (have_rows('flex_content_field')) {
        the_row(); // forgot this line
        $layout = get_row_layout();
        // and the rest of your flex field output
      } // end second while have rows
    } // end second if have rows
  } // end first while have rows
} // end first if have rows
