Im using this code

<?php

// check if the repeater field has rows of data
if( have_rows('repeater_field_name') ):

 	// loop through the rows of data
    while ( have_rows('repeater_field_name') ) : the_row();

        // display a sub field value
        the_sub_field('sub_field_name');

    endwhile;

else :

    // no rows found

endif;

?>

I want to print all the sub_fields values, without knowing their names. how can i do that easily?

I was trying to populate an array with the repeater object and get it out, but i suck at php.

thanks for help! 🙂

Hi

instead of using a while loop, if you get the field directly via the get_field function, it will actually return you an associative array with all the sub fields value. Then you can just run a normal php’s foreach on it to do whatever you want.

<?php
    $values = get_field('repeater_field_name')? : [];
    foreach ($values as $key => $value) {
        // do what you want here
    }

Cheers 🤓

thanks for your help. I still don’t understand it. I tried removing the while loop and using your solution and I’m able to print all the keys and value but onyl from the first row of the array:

if($check['type'] == 'repeater'):
									if( have_rows($name) ):
											$values = get_field_object($name)? : [];
											foreach ($values as $key => $value) {
       											$content .= "key: $key - value: $value </br>";
   											 }
									endif;
								elseif($check['type'] == 'wysiwyg'):
									$content .= $value;
								else:

								endif;

and what I’m actually trying to exactly do is this:

if( have_rows($name) ):
										
										while ( have_rows($name) ) : the_row();
										
											// write method to print subfields without knowing their names.
											$content .= get_sub_field('effect_name') . "</br>";
											$content .= get_sub_field('effect_magnitude') . "</br>";
											$content .= get_sub_field('effect_description') . "</br>";

										endwhile;
									endif;

but without knowing the names ‘effect_name’, ‘effect_magnitude’ and ‘effect_description’

ok i solved this thank you so much. finally it worked for me like this to print all the values in subfields:

if($check['type'] == 'repeater'):
									if( have_rows($name) ):
											while ( have_rows($name) ) : $the_row = the_row();
    											foreach ($the_row as $key => $value) {
        											$content .= "$value </br>" ;
   													 }
   											endwhile; 
									endif;
								elseif($check['type'] == 'wysiwyg'):
									$content .= $value;
								else:

								endif;

Hi vandelay, do you still use this method? and if so any chance of the exported JSON so can see how you have set it up please
